Was bedeutet der Fehlercode?
The engine control module (ECM) keeps watch on the exhaust gas recirculation (EGR) function. The code means the EGR control is not right, that is, more exhaust gas is being recirculated to the intake than the engine management has requested. The fault lies in the EGR valve or its wiring and can be read while the engine is running.
Mögliche Ursachen
- The EGR valve is seized, for example from dirt or soot
- Damaged EGR valve
Was Sie tun können
- 1Check the intake system for leaks and damage
- 2Check the EGR valve and its connections for soot and dirt, and clean the valve if needed
- 3Check that the valve connector is fully engaged and free from oxidation
- 4Have a workshop activate the valve to check it is not seized; after replacing or cleaning it, the valve needs adapting
