| Exhaust gas recirculation system: engine code AWC |
WARNING | When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |
| t
| Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions. |
| t
| Ensure that there is sufficient clearance to all moving or hot components. |
|
Note | t
| The function and regulation of the exhaust gas recirculation system is checked by self-diagnosis of the Motronic control unit -J220-. |
| t
| Pulsed control enables every conceivable valve position. |
| t
| The exhaust gas recirculation valve with cone shaped plunger ensures that various aperture cross-sections are possible at different plunger lifts. |
