Was bedeutet der Fehlercode?
The code is set when the front fog lamp relay is switched on and the central electronic module (CEM) finds the front fog lamp in contact with battery voltage. The fault is intermittent, so it may not be present at the moment.
Mögliche Ursachen
- The front fog lamp relay circuit is short-circuited to supply voltage
Was Sie tun können
- 1Check that the fog lamp relay is correctly fitted and that its contacts are clean and tight
- 2Look for chafing or loose contacts at the relay wiring, especially if the electrical system has recently been worked on
- 3With the ignition off, use a multimeter to check that the wire to the relay has no voltage
- 4If the fault returns, have a workshop check the relay and the circuit, since intermittent faults can be hard to find
Symptome, die Sie bemerken können1
- The front fog lamps do not work
