Common ECU Failures

Mercedes W204 ECUs can develop internal electronic faults resulting in:

• Crankshaft sensor signal not processed correctly

• Injector driver failure

• Ignition coil driver failure

• Cylinder 3 misfire faults

• Internal circuit board faults

• Water damage

• Communication failures

• Power supply circuit faults
   

It is common to see vehicles where the crankshaft sensor, ignition coils or injectors have already been replaced but the fault remains due to an internal ECU issue.
