EGR Adapter Audi/VW 3.0L Part No. 069-3391
EGR System Consists of:
• ColdsideEGRvalve(afterEGRcooler)controlsexhaustgasesforproperemissionscontrolofNoxgases
• EGRcooler(controlstemperatureofexhaustgasestotheairintaketotheengine)• EGRcoolerbypassvalve(controlsexhaustflowtemperaturetotheairintakefromtheexhaustthrough
theEGRcooler)• EGRtemperaturesensor(measuresEGRcoolerexhausttemperatureandefficiency)• Swirlflaps(controlairflowunderdifferentenginespeedandloads)–closedwhenengineisatidleandat
lowenginespeeds–below1250rpm
These items are critical for proper emissions management control and must be cleaned on a regular basis for optimum efficiency.
First steps before any service can be performed:
1. AddPart#400-3012DieselTune™MaxStrengthFuelInjectorCleanertothevehicle’sfueltank.2. Removeplasticenginecover.3. Ifengineishot,theEGRcoolermustbecooled–seestep9.4. SpecialtySocket–seenextpage

Note: If no scan tool available unplug and reconnect the EGR bypass valve actuator vacuum hose (see figure below) several times through out this step.
14.Usingascantool,commandtheEGRvalveandswirlflapsopen.Note: If no scan is available reconnect the EGR wire connector, raise engine rpm to 1500 this will allow the EGR and the swirl flaps to open.
15.Openfluidvalve.ContinueserviceuntilEGRtoolisempty.Note: At any time during the intake service (step 15) you hear a diesel knock sound, turn fluid valve to closed position for 2 minutes. After two minutes then turn fluid valve to open position and continue service. Let the vehicle operate for an additional 5 minutes and rev the engine several times to clear all residual fluid.
