Was bedeutet der Fehlercode?

The module has been told that the additive dosed into the main fuel tank is too small to make sure soot in the particle trap burns off completely. The code can also be set when the module cannot communicate with the ADM. The fault may therefore lie in the ADM or in the CAN communication.

Mögliche Ursachen

Fault codes are set in the additive dosage module (ADM)
CAN-related fault codes in the central electronic module (CEM)

Was Sie tun können

1Read the ADM fault codes first, then the CEM codes, and note which are stored
2Remedy the ADM faults and the CAN-related codes in the CEM first; this code is cleared once they are remedied and erased
3Check that the ADM connectors and CAN wires are fully seated and free from oxidation, and look for chafing in the harness
4Clear the fault code once the faults are remedied and road test the car to see whether it returns
