Was bedeutet der Fehlercode?

The fault is intermittent: the CEM registered a break in the signal to the front washer relay on an earlier occasion, but the break is no longer present. Front washing may then fail.

Mögliche Ursachen

Break in the signal wire
Break in the power supply to the relay
Faulty relay

Was Sie tun können

1Clear the code and check whether it returns with the ignition on
2Check that the relay for the front washer motor sits firmly and is not loose
3Check that the contacts are clean and free of oxidation, and that the connector has no play
4Use a multimeter to check that the supply to the relay has no break, with the ignition on
5If the fault returns, have a workshop replace the relay if the contacts and wiring are in order
