All relevant coding and adaptation values have been transferred
from the OLD (ORIGINAL) cluster to the REPLACEMENT (NEW or USED)
cluster. Immo 3 Audi vehicles typically use adaptation channels
060, 061 and 062 for the internal installation list since they do
not have address 19-CAN Gateway. If in question, run a complete
AdaptationControl Module Mapwith the old module installed. Immo 3
VW vehicles typically use short coding in address 19-CAN Gateway.
If the original value is 00006, which is common, recode the new
unit to the same value to refresh the internal gateway installation
list. Make sure to have BOTH PIN's, from the OLD (ORIGINAL) and the
REPLACEMENT (NEW or USED) instrument cluster. Make sure to have the
Radio Code (for factory radios only).

Guidepenbryn18-01-10, 23:16Rating:(1 votes - 5.00 average)
I am prompted to write this short guide due to the general
misinformation and unjustified 'fear' people seem to have with
regard to the Siemens/VDO immobiliser and it's use in the T4 1.9TDI
conversion. In short, if it worked in the donor car then there is
absolutely no reason why it should not work in your van.
Before I give a detailed description of the Siemens/VDO type
immobiliser (commonly known as Immobiliser 2) as fitted to most
late 94->2000 VAG cars, here's a quick overview:
Passive Immobilisation
The introduction of passive vehicle immobilisation by the major
car manufacturers came about because the brokers for the Insurance
Federation of Germany began to refuse to underwrite vehicles that
did not have passive electronic immobilisation systems fitted. The
use of the word 'passive' meant that no direct intervention was
required by the user to 'activate' or 'deactivate' the system. Some
of you may remember Peugeot marketing an immobiliser in their
vehicles in the 1990's which required the user to input a PIN on a
keypad before starting the vehicle - this is an example of an
'active' system as it requires user intervention.
So how does VW Immobiliser 2 work?
The passive Siemens/VDO transponder system fitted to most VAG
group cars at least between late 1994 and 2000 comprises of three
primary components: 1) The immobiliser control unit, 2) The key (a
transponder or RFIC device - you may hear people call it a 'chip')
embedded within the body of the key or fob, and 3) The key reader
antenna attached to the ignition barrel. The immobiliser 2 control
unit interacts with the ECU and instrument cluster, (and body
electronic systems on some vehicles). It is important to note that
the key is paired (or matched) to the immobiliser not the ECU.
The Siemens/VDO immobiliser control unit:
The transponder RFIC (found inside the key):
The key transponder reader antenna array:
When an attempt is made to start the vehicle, the control unit
transmits a burst of RF (Radio Frequency) energy at a given
frequency - to the key reader antenna around the ignition barrel.
The RFIC or 'chip' in the key contains a tuned circuit which is
matched to the frequency of this burst of RF, as a result a small
voltage is then generated by induction within the transponder
device. This small amount of induced RF energy is used to charge a
capacitor, which is used to power the RFIC device. The RFIC then
responds by transmitting (again by RF), a unique individual thirty
two (32) digit identifier (number). This all happens seamlessly and
in microseconds, so the user never noticesIf the immobiliser 2 unit
'recognises' the identifier transmitted by the RFIC as a 'known'
vehicle key, it then sends a message to the ECU to allow it to be
'unlocked' and hence allow the vehicle to start. A common sign of a
faulty immobiliser system is that the vehicle will start but will
only run for 1 or-so seconds.The two main manufacturers in
immobiliser transponder (RFIC) technology are Philips (see pic
above), and Texas Instruments - both of which are used on VAG
vehicles. Although it is Philips devices which are used in most of
the immobiliser 2 systems.
So what do I need to know when wiring the immobiliser for the
1.9 TDI conversion?
From the donor car, you will need:
1) Siemens/VDO immobiliser control unit (as pictured above),2)
Original key (or RFIC device from the key as shown in pic above -
not strictly required, but makes life easier - see FAQ )3) Key
transponder reader4) The ECU.
There are two connectors on the control unit:
One is a 3 pin connector the other is 6 pin.
* The 3 pin goes to the transponder key reader antenna array.*
The 6 pin connector is numbered (as you can see) pins 1 to 6
So starting at the start:
Pin 1 - Black , connect this to an ignition switched +12v
supply
Pin 2 - Grey/white, goes to the ECU (pin 61 for Bosch 68-pin
ECUs)
Pin 3 - Grey goes to the OBD II diagnostic socket, but changes
to a grey and white at the diagnostic socket end.
Pin 4 - Brown, ground
Pin 5 - Not connected
Pin 6 - Brown, ground
Pin 1 was originally connected to the donor vehicle instrument
cluster and got it's +12v supply from there.If you removed the
cluster( therefore no +12v to pin 1) the immobiliser will not
function - engine will start and run for a second and then
stop.
Alternatively, if your donor vehicle came with the above
immobiliser (usually made by TEMIC or Sagem, but Siemens/VDO also
made them), then usually they will have an 8-pin connector for the
power and diagnostic functions rather the the six pin connector
outlined above it is connected as followed:
Pin 1 = B+ (12V)
Pin 2 = +12_IGN
Pin 3 = N/C
Pin 4 = GND
Pin 5 = GND
Pin 6 = N/C
Pin 7 = Engine k-line
Pin 8 = k-line diagnostic socket
FAQ
1. Is there any way I can bypass the immobiliser
Simple answer: 'No' otherwise this would defeat the purpose of
the manufacturer fitting an immobiliser to begin with.
More complex answer: 'Yes' - you can have the firmware of the
ECU modified such that it does not expect to receive a message from
the key via the immo box thus doing away with the immobox reader
coil and key altogether. This can be expensive however ~85GB at the
time of writing (11/2010).
Another "solution" is to fit a immobiliser emulator, which are
available from a 3rd party companies, cost at the time of writing
is about 55. However it may just cheaper and easier to buy a
key/immo box pair from a local scrapyard
Personally, I do not understand why anyone would want to remove
the immobiliser. It will after all make your van harder to steal
which for me at least is a always a bonus.
2. I bought an engine/harness/immobiliser but I didn't get any
key/key was lost/incorrect etc.. Is there any way I can get a new
key(s) programmed?
Yes, some locksmiths/dealers/independents will do this but only
if you have the SKC (Secret Key Code - comes on a tag with the car
when it was new - most have long since been lost). Others
locksmiths/dealers/independents can do it without the SKC, but they
charge accordingly ~50-80.
If you have the SKC and a fully registered copy of VAG COM/VCDS
you can do it yourself.
Alternatively, for a small fee (strictly to cover costs), If you
send me the immobiliser I can extract the SKC from your immo box so
that new keys can be coded to your immobiliser, or if you send me a
new key I can adapt that to the immo. (PM me for details)
Troubleshooting
You will not be able to do any diagnosis without a copy of
VAGCOM to interrogate the immobiliser
The immo system (apart from a power supply) essentially depends
on two things: 1) A good signal from the key and 2) A reliable link
to the ECUThe only way to test the integrity of these is with
VAGCOM
When installing the antenna (which is often incorrectly
described as a coil because of its shape),you should never put the
key 'in-the-middle' of the antennato test the immo, this will only
result in a poor/no signal to the immo box. The best way to ensure
a reliable signal is to fit the key reader to the ignition barrel
in the van and the correct transponder to the key. The reason for
this is that the RF signal that the transponder generates is so
small that positioning is critical. In addition to this, the
ignition barrel acts as a ground-plane for the antenna array to
improve the propagation of the transponder signal. VAGCOM will
report 'intermittent of poor signal from key' type faults if you
problems in this respect.
If you have problems with the datalink k-line to the ECU, then
either the immo will report a comms failure or the ECU will give
you a 'Engine start blocked by Immobiliser'.
Hope this helps with understanding and wiring of the immobiliser
system and clears up any mystery that surrounds the 'magic' of VW
immobiliser 2.Removed/Reinstalled Instrument Cluster - Now
Immobilizer Will Not Let Car Start
I removed my instrument cluster two weeks ago, had some LED work
done on it, and have reinstalled. Now the Immobilizer-3 light
blinks, and when I try to start the car, it does the typical
running for 2 seconds and dies.
I followed the troubleshooting found
here:http://www.myturbodiesel.com/1000q_h...mmobilizer.htm
Specifically, I've done the following with no success:
- Charged up my battery and checked voltage is greater than 12.5
V (I still have the original OEM battery with 86,000+ miles and 6+
years on it)
- Tried to start the car with both of my keys/fob
- Leaving the key in the ignition to "ON" but not start for a
few minutes to see if the immobilizer light would stop flashing
- Disconnecting BOTH negative and positive terminals of the
battery, and then touched the cables to each other for about 1
minute, while not attached to the battery
- Ran VCDS, which gave me plenty of faults related to the
immobilizer

Choices are:
- Procedure for matching keys to vehicles with Immobilizer in

- BRAND NEW ECU (doubt this one, since I did not swap my
ECU)
- Used ECU (doubt this one, since I did not swap my ECU)

with Immobilizer III (doubt this one, since I did not swap my
instrument cluster)
Can anyone help, PLEASE!!!__________________Links:2003 Jetta GLS
TDIwith DeutschlandGnther-Tunespecific to my performance
modifications-Platinum GrayThe original codes were probably stored
as a result of turning the car on when the instrument cluster was
not in the vehicle or not properly installed, as the CAN gateway
and the Immobilizer are all physically present in the instrument
cluster.
Clearing the codes and trying it again seems to have pointed to
the issue : The immobilzer donut (black circular thing around
ignition key slot) has having an issue reading the key. The donut
cannot read the RFID key tag, therefore it can't compare that value
to the values stored in the EEPROM as authorized keys.
Easy stuff: I'd verify that the connectors on the instrument
cluster are plugged in properly for starters. I'm assuming they
are, they are pretty hard not to get correct.
Second, I'd look for damaged pins in the cluster housing and
damaged pins or wires on the connectors going to the cluster. I
gave up my MkIV Bentley, so I have no wiring diagrams, however the
donut has a connection to the cluster.
If neither of those work, I'd see if you can get your hands on
another Immo3 instrument cluster, even temporarily. Your car will
likely not start, but it would tell you if the donut that reads the
keys are still having issues. (You'd get a code about unauthorised
key if the donut can read a key when connected to a different
cluster, not a signal too low from key.) This will determine if you
have a cluster problem or an immo donut problem. Any 1J0 920 xx6
cluster or 1J5 920 xx6 cluster will suffice for this test, gas or
diesel, etc..
I say try a new instrument cluster first as I'm assuming you did
nothing while the cluster was down and out to the wiring or
connections to the immo donut or anything else in the steering
column. Depending on what resources are available to you, it might
be easier for you to trace down the wiring from the cluster to the
immo donut than get your hands on another instrument cluster.
If you did happen to be poking around in the steering column,
ensure that all the grounds are good. There's a grounding post in
there that has a bunch of brown wires connected to it. Make sure
it's not tarnished / corroded and that the screw/bolts are
tightened.
This is a crappy situation.
BTW: Do you happen to know your 4 digit Immo
SKC?__________________- Don'97 Jetta TDI - 135K - R.I.P.

Sold.'09 Jetta TDISedan - Sold!'14 Passat TDISEL - Blue / Black
LeatherAs for your proposed solution, I don't think this is going
to be the smoking gun fix.
The cluster isn't saying the key isn't authorized, it's saying
that the signal from the key is too low to get a reading.
Re-Matching keys isn't going to do you much good if the immo donut
/ cluster can't get the ID number from the key. See where I'm going
with this? If the keys had become unmatched you would get a fault
indicating "Unauthorized key". This means that it successfully read
the ID from the key, however it did not match one of the key IDs
that were in the EEPROM as adapted.
If the ground for the Immo donut is weak or bad, it would cause
this issue. Broken wiring as well as a bad donut would also cause
this fault.
The Immo donuts have been known to go bad on occasion, and there
was an issue in early NBs with Immo with some kind of a loose
connection or bad immo reader causing the same conditions you are
seeing.
It could be coincidence that your Immo donut went bad at this
time, however it's pretty unlikely. Thats why my first suggestion
would be to get a new cluster, then to trace wiring. If no other
cluster is available, check wiring.__________________- Don'97 Jetta

Blue / Black Leather VW and Audi key, remote, and immobilizer FAQ
and troubleshootingThis FAQ article describes how the immobilizer
system works, how to replace the smart key in your VW or Audi
remote, and troubleshooting steps/and how to bypass/delete the
system.
The immobilizer is a theft deterrent system located in the
instrument cluster, the main car computer, a radio frequency
identification (RFID) transponder chip in the VW or Audi smart key,
and an antenna at the ignition cylinder. You cannot do an
immobilizer bypass with normal "car theft" tools so don't bother
asking. If your VW is 1999 or earlier and sold in North America, it
shouldn't have an immobilizer. If your car has the yellow car/key
symbol on the instrument cluster when you turn the key to "ON",
(shown activated below) it has an immobilizer. This light comes on
for a second but quickly goes out when turning the car on and all
is normal. If it stays on, you have an issue.
When buying or programming a new key, you must use a key that
corresponds to the same immobilizer generation and keyless entry
type and sync it to the immobilizer. If you need a new key, read
the summary below and refer to the detailed instructions at1000q:
mk4 key programmingor1000q: mk5 key/remote FAQ. If you have an Audi
A3, the steps in VW mk5 mostly apply. If you have a mk3 VW you
don't have an immobilizer if you're in North America but
here's1000q: mk3 key programming FAQanyways. Audi have the same
immobilizer systems but in different generations than VW so the
same general procedures apply.
The main symptom of a faulty system or activated immobilizer is
that the engine shuts off after a second or the yellow car/key
symbol on the dashboard flashes. A very low car battery or car
battery removal could also cause the immobilizer to become active.
On rare occasions it's triggered for unknown reasons - see the rest
of this page for troubleshooting. Below is a video demo of the
immobilizer shutting off the engine. If it doesn't act like this
it's not the immobilizer. See the starter troubleshooting
pages.
The immobilizer chip has a range of about 1" through plastic and
about 3" when out of the key (bare chip). Although the computer
constantly monitors if the chip is correct or not, it won't shut
off the engine after the first few seconds of the car engine
starting. I'm almost certain that it won't shut off the engine if
the chip signal is interrupted after a few minutes. (I didn't want
to test it by driving around without the chip signal). If you want
to be very careful, don't let the key get exposed to high strength
microwaves. Standing next to a microwave won't do anything but
putting the key into a microwave will damage the chip. One nice
thing about the immobilizer system is that if a key is stolen/lost,
having the keys reset by the dealer or someone with the correct key
matching tools will prevent the lost key from operating the car as
normal. After the keys are reset, the old metal key can still open
the doors and start the engine but the immobilizer won't let the
engine run for more than 1 second. Because of this, when you reset
the immobilizer, all keys must be present or else the old ones
won't work as intended anymore.
The first step in getting a new Audi or VW Smart Key / remote
key fob
The remote has 3 main components: the keyless entry circuit
board, the metal flip key to open the doors and insert into the
ignition, and the immobilizer chip which talks to the immobilizer.
Each is a separate system. The immobilizer chip is glued in the
flip key half and cannot be purchased from VW separately. You can
buy them on ebay as the megamos chip. Each must be correct for the
Smart Key to work as intended. For example, even if you buy a cut
metal key, the unprogrammed immobilizer chip will shut the engine
off after a second. The immobilizer has nothing to do with
unlocking the doors, the alarm, or the starter - it still lets you
start the engine but if it's not programmed it will shut the engine
off.
Here is a mk4 key 1998-2009. As you can see, the immobilizer
chip (white arrow) uses no battery - it's an RFID chip energized by
the pick up antenna on the ignition coil.
2010 and newer keys look like this. They changed the key to work
with KESSY, the keyless entry and start system. Even if you don't
have KESSY, the key still looks like this. The immobilizer chip is
the long black rectangle soldered to the board. At this time, I
have no idea where to buy the chip by itself.
-If the car has no immobilizeryou can program the keyless entry
yourself and have a new key cut anywhere which does a "reverse cut"
side milled key found on VW - Audi. Again, if your instrument
cluster doesn't have the yellow car/key symbol you don't have
immobilizer.
-If the car has an immobilizer and you have an existing broken
key(broken remote or flip key), remove the immobilizer chip from
the old key and swap it into another new or used key to prevent the
immobilizer from acting up. The chip looks like a small grain of
rice, pictured above and below. Then you can program the keyless
entry yourself. If you need a new metal key, just take the key
apart and swap the bad switchblade key with a new cut one. You can
cut the new metal key anywhere which does side mill/reverse
cut/laser cut VW - Audi sidewinder keys.
-If the car has an immobilizer and you don't have an old keyto
salvage the chip out of, you must read the notes below about the
SKC code and key variations.
For generation specific information on keys including how to
take them apart, refer to the links at the top or search this FAQ.
Audi followed different generations but the articles will work for
them.
How to use a remote starter with an immobilizer equipped
carRemote starters still require a valid immobilizer signal just
like a regular key. If you buy a remote starter system, make sure
it has the relay signal box approved for VW/Audi signals. You must
place the key or just the half with the chip inside the relay box.
The relay box is then hidden somewhere in the car. When you use the
remote starter, it relays the immobilizer signal inside the hidden
box to the antenna around the ignition cylinder ring and works like
OEM. They will work with any 1998-present system.
How the immobilizer works and immobilizer differences by yearIf
you have the yellow car symbol pictured at the top on the
instrument cluster, you have an immobilizer. When you turn the car
on, the antenna around the ignition switch induces a voltage in the
RFID transponder chip. When the key is recognized, the immobilizer
module, part of the instrument cluster, sends a random number to
the key. The module and key both do a simple calculation and if
they match, normal engine starting is allowed. Immo 3 also tells
the ECU to do a calculation. Because of this, you can swap ECU on
immo2 cars but not immo3 or above.
The three main types of TDI immobilizer are immo2, immo3, and
immo4. VW up to 1999 sold in North America don't have an
immobilizer. Cars sold in Europe or the rest of the world may have
immobilizer 1. These used a separate physical immobilizer box.
1999-2000 should have immo2. 2001-2005/6 use immo3. 2005/6-present
use immo4. Around 2010, VW keys changed their design even though
they still use immo4. As of this writing, immo5 is only found on
the newest Audi. Immo2, 3, 4, and 5 keys are not compatible. In
other words, if you have an immo2 car, you can only use an immo2
key because the chip is different.
Immo 4 uses no module - the immobilizer is a function built into
multiple parts.
As late as 2001, there were some B5 Passat that didn't have any
immobilizer. All Jetta, Golf, and Beetle definitely had them by
this point.
Cabrio and Eurovans have no immobilizer warning light and the
immobilizer module is a separate physical box from the instrument
cluster.
Telling the difference between immobilizer 2 and 3If your car is
in a transition year and you're not sure if you have immobilizer 2
vs. 3, connect a ross tech VCDS to the obd2 port and access the
immobilizer module. Go to measuring block 81. If you see your VIN
number it's 100% not immobilizer 2.
-If you have no immo- you can swap keys, ECUs, and instrument
clusters without any special programming. This assumes that the
part numbers and software coding (settings) are the same.
-If you have immo2- you need the SKC to use a new key or
instrument cluster but you can swap the ECU without any special
programming. It has an emergency drive function that will let you
drive to the dealership or mechanic for them to fix but you must
know the SKC code. You can buy a used key and it will work if you
reprogram the immobilizer chip using the SKC.
-If you have immo3- you need SKC to use a new key, instrument
cluster, or ECU. You cannot use used keys from another car since
the immobilizer chip can only be set once to a car (unless you swap
out the chip with your current one). Again, the chip-key half is
separate from the remote keyless entry half.
-If you have immo4- found on mk5 and mk6 Volkswagens and newer
Audi. You need SKC to use a new key, instrument cluster, or ECU.
You cannot use used keys from another car since the immobilizer
chip can only be set once to a car (unless you swap out the chip
with your current one). Same restrictions as immo3.
-Immo5- found on 8T generation Audi A4 (2007/2008+) and 8k
generation Audi A5 (2007+).
The cheapest and easiest way to get a replacement VW or Audi
Smart keyBecause of the variation in build dates, immobilizer
generations, and remote compatibility, the easiest way to get a
replacement key is from the dealer. Dealers are expensive but they
can match the key to the car and if it's the wrong part they'll
take it back. If you buy an ebay replacement key for an immobilizer
car you have to figure out how to program the immobilizer, if your
car was a transition year, and there are no refunds once you cut a
key. Some won't touch ebay keys.
The cheapest way to get a new key from the dealer is to buy a
cut key from an online OEM parts dealership and take it to the
local dealer for programming. The online dealership can cut it if
they have your VIN number. Regardless of the number of keys, they
typically charge for 1 hour even though it really only takes less
than 15 minutes of actual work. If they charge you for 1/2 hour,
it's very fair. The smart key immobilizer must be programmed in
person with someone who has access to the SKC.The part numbers
below are only a guide, double check the correct part number with
your parts vendor, this website is not responsible if you order the
wrong key!
The absolute cheapest way to get a new key is to buy the
programming tools yourself, buy a cut key online, and when you're
done, resell the programming tools. The initial investment in the
tools isn't cheap and most people end up keeping their VCDS tool
since it's so useful. If you can get the dealer to only charge a
half hour for programming, that is the cheaper route.
NOTE: The newest keys 2007+ on most VW models and all 2010+ keys
use additional encryption on the immobilizer chips. As of this
writing, there are no aftermarket tools to program the immobilizer
key yourself. In this case you must to go to the dealer.
Technically speaking, you can use a qualified locksmith as a result
of a class action lawsuit about smart keys but these specialized
shops are few and hard to find. Due to the expensive equipment they
have to rent from VW, they're usually not any cheaper than the
dealership.
-If you have a car with build date 11/98-09/00, (about model
year 1998-2001) your remote probably looks like#1pictured below,
part number should be VW# 1j0 959 753 f-If you have a car with
build date 10/00- 05/01 (about model year 2000-2002), you probably
have the remote that looks like#1, it should be VW# 1j0 959
753t.
-If you have a car built after 05/01 (about model year
2001-2002), you should have remote #2, it is either VW# 1j0 959 753
am or 1j0 959 753 dc
-If you have an mk5 body VW up to around 2006-2007, you have
immo4, your Jetta remote is either VW# 1j0 959 753p, or 1k0 959
753h.
-If you have a mk5-mk6 body VW 2010+ your key is a new style and
you can't do much with them since there are no aftermarket tools to
get the SKC. Go to the dealer.
How to disable or bypass the immobilizer system in your VW or
AudiLong story short, you have to bench flash the ECU with new
programming to completely delete the immobilizer system. The immo
light will still blink but the car will always start.. If you have
an immo2 car and know the SKC code you can do an emergency bypass
so that you can drive to the dealer. You can also order bypass
boxes online. I've never used one since I've never had to and they
are reported to be buggy/not always work.If it was too easy and
fast to bypass it wouldn't be a very effective anti theft device,
would it?
If you wish to remove the immobilizer function from the car you
can only do this through a specialized chip tune. This requires you
to remove the ECU from the car and ship it to

Problems that are NOT related or caused by the immobilizer
system-If the starter does not engage or the engine does not "turn
over" at all, this is not an immobilizer problem. You probably have
an ignition switch or starter problem. For mk3 and mk4 cars,
see1000q: starter FAQ and troubleshooting. For mk4 Passat,
see1000q: B5 Passat starter fix. For mk5 Jetta or Golf, see1000q:
mk5 starter.
-If your car shuts off more than 3 seconds after engine start it
has nothing to do with the immobilizer. The immobilizer shuts the
engine off in the 1st second.
-The chip inside the key does not have a battery or other
internal electricity source. It's an RFID chip and is "excited" by
the antenna around the ignition switch. Shaking the key or changing
the remote fob's battery will not fix any problem with the
immobilizer. Just look at the pictures above - there are no
batteries for the immobilizer chip. In the case of the 2010 and
newer keys, if the battery dies you just hold the key next to where
the ignition should be. The RFID signal will still be read.
-The immobilizer system has nothing to do with opening or
unlocking the doors. The immobilizer will not be activated by the
alarm system - the alarm system affects the starter. The
immobilizer's ONLY action is allowing the engine to stay running a
second after starting it. Again, the keyless entry and immobilizer
are separate.
-It has nothing to do with the power of the car. If your car has
poor performance or fuel economy, it has nothing to do with the
immobilizer. See1000q: limp mode for the TDIand1000q: constant low
power or can't revfor more details.
More detailed information below is separated into immo-2 and
immo-3 sections because they have different procedures. I'm working
on an immo-4 section, please refer to immo-3 and your bentley
manual for now. Remember, to work with the immobilizer, you MUST
have a vag-com/VCDS tool. You cannot use a generic code scanner,
you must use a VCDS cable. You can only use an emergency start
without a VCDS and even then you must know the SKC code.Basic
immobilizer troubleshooting1.First, make sure the car battery is
charged. A low battery can cause problems with the immobilizer. It
also results in low cranking RPM during engine start - this will
cause the ECU to prevent fueling.
2. Try another key - you should have a valet key and spare key
that also have an immobilizer chip in them. If they work, then you
have isolated the problem to the key. Again, there is NO battery
for the immo chip, it gets power from the ignition switch
transmitter. You can try reprogramming the chip with the procedures
linked to below.
3. Check for error codes - scan the car with a VCDS to see if
there is a problem with the system and refer to the appropriate
procedure below.
4. You can try just leaving the key in the ignition to "ON" but
not start for a few minutes. Many people report that the light just
goes away after 10 minutes as if nothing ever happened. This and
the next solution appear to have something to do with a capacitor
discharge or something resetting. It sounds strange but many report
that it works.
5. Disconnect the battery negative terminal and step on the
brake pedal - this turns on the brake lights and discharges any
stored electricity. This may reset the immo system. I've heard that
disconnecting BOTH negative and positive terminals of the battery
and then touching the cables to each other only, while not attached
to the battery can also reset it. I think that it takes more time
and does the same thing as disconnecting the negative side and
turning on the brake lights. Again, don't touch the cables to the
battery, touch them only to each other while both are disconnected
from the battery - you don't want to short the battery out.
6. Check wiring and plugs at instrument cluster and pickup coil
at the ignition switch, there is a chance it could be faulty. You
could try wiggling the key in the slot in case there's a problem
with the pickup coil. However, the range of the antenna/chip is
about 1" so it's definitely not a range problem.
7. Put a trickle charger on the battery, put the key to the "ON"
position and leave it for a few hours. If it didn't reset after 10
minutes it's been known to reset after a few hours and never appear
again.

cluster swapping: this is where the immobilizer is located, resets

a VCDSGeneral immo3 information and troubleshootingThe immobilizer
is an anti-theft device located in the instrument cluster using a
chip in your key with an antenna or "pick up" at the ignition
cylinder. This chip is pictured below. It's not possible to bypass
the immobilizer with normal "car theft" tools so don't bother
asking. If you have an immobilizer 3 key you can only replace it
with an immobilizer 3 key. If you're looking only to replace the VW
smart key, see1000q: VW key/remote FAQfor more details. This page
details the other parts of the immobilizer system and immobilizer 3
specific procedures.
The main symptom of a faulty immobilizer system is the car
shutting off after two seconds or the anti-theft light on the
dashboard flashing. A very low car battery or battery removal could
also trigger the immobilizer. Some people report certain computers
with wireless internet activated in the car interfering with the
transmitter in the key of the immobilizer. If you want to be super
careful, don't let the key get exposed to high strength microwaves.
Standing next to a microwave won't do anything but putting the key
into a microwave will quickly damage the chip (and possibly the
microwave).For immo3: you need SKC to use a new key, instrument
cluster, or ECU. You cannot use used keys from another car since
the immobilizer chip can only be set once per car. The reason why
is because it uses a rolling immobilizer code instead of a simple
transmit 1 code like earlier systems.The immobilizer chip has a
range of about 1" through plastic and about 3" when out of the key.
Although the computer constantly monitors if the chip is correct or
not, it won't shut off the engine after the first few seconds of
the car engine starting. I'm pretty sure that it won't shut off the
engine even if the chip signal is interrupted during driving. (I
don't want to test it by driving around without the chip
signal).
VW Smart key replacement part numbersThe part numbers below are
only a guide, double check the correct part number with your parts
vendor, this website is not responsible if you order the wrong
key!-If you have a car with build date 10/00- 05/01 (about model
year 2000-2002), you probably have the remote that looks like#1, it
should be VW# 1j0 959 753t.-If you have a car built after 05/01
(about model year 2001-2002), you should have remote #2, it is
either VW# 1j0 959 753 am or 1j0 959 753 dc, it should have immo 3.
You don't have immo 4 unless you have an mk5 car.
Telling the difference between immobilizer 2 and 3If you still
can't figure out if you have immobilizer 2 or 3, use a ross tech
VCDS to access the immobilizer module. Go to measuring block 81. If
you see your VIN number it's 100% not immobilizer 2.

despite the immobilizerRemote starters will work but they must have
a booster box approved for the VW/Audi chip. You put the key or
chip inside the booster box and hide the box in the car. When you
use the remote starter, the booster box uses the immobilizer chip
in it to pass a valid signal to the immobilizer antenna on the
ignition coil pickup. It will then work like any other remote
starter. Make sure that the car is in park or neutral (if manual)
whenever using a remote starter.Problems that are NOT related to

ProceduresMirrored from ross tech's siteRecoding a new key
without a VCDS OR recoding it with a VCDSWhen you buy a replacement
key, you must have it matched to work with the immobilizer. The
remote unlock/lock, etc., has nothing to do with the immobilizer,
so that must be matched separately. You can either use a VCDS to
recode it or you can take the old key apart and just remove the old
RFID chip and put it in your new key. The RFID chip is just glued
in place, there are no batteries for the chip. The only batteries
are for the remote unlock.To reuse the existing immobilizer chip,
pop it out (pictured below) and swap it with the new key's chip.
Use some water based glue to help hold it in place. See1000q: mk4
key FAQfor a detailed procedure, this article is more about the
immobilizer.Image of key disassembled - note that the immobilizer
chip (white arrow) uses no battery - it is energized by the pick up

change back to miles. To do this, consult the Factory Repair Manual
for your vehicle. Here is an example:
[Select][17 - Instruments][Recode - 07]Change the 3rd digit from
a "3" (Canada) to a "2" (US)[Do It!]
Confirm that the odometer in the car now shows miles, not
kilometers. Make sure that the mileage reading is correct.Note: If
you are installing an instrument clusterthat has ever been
installed in another car, you must insert the following step. Also,
bear in mind that you will not be able to change the mileage of a
cluster that has more than 100 km on the odometer):
8.5 [Login - 11][Use 7-digit PIN/SKC]Enter the 7-digit PIN for
theUSEDInstrument Cluster, Date on which the PIN wasgenerated by
the dealer,along with the Workshop Code (WSC) and the Importer
numberof the dealer that generated the code.[OK]This should
effectively "wipe out" the previous matching.Immobilizer 3

Immo-3 knows your car's VIN. Access 17-Instruments (or separate
25-Immobilizer on vehicles that are set up that way) and look at
the first "Extra" field.
If you see something like: "Immo-ID VWZ7Z0W0648696" You've got
Immo-2 (or maybe even Immo-1 in earlier non-US models).
If you see something like "WVZKB58001H231169 VWZ7Z0W0648696"
You've gotImmo-3. The first 17-digit string is the VIN. The second
14-digit string in the Immo-ID.022Engine Start PermittedECU
