Was bedeutet der Fehlercode?

- Break in the supply wire between the cornering lamp and the left main headlamp control unit (LHCU)
Was Sie tun können

- 3With the ignition off, check the wire to the lamp for chafing, pinching and loose connections, especially at the lamp housing
- 4With the ignition off, use a multimeter to check whether the supply wire to the lamp is broken or has contact with earth (the body)
- 5Remedy the fault and clear the code. Switch the ignition off and on to check the lamp. If the fault remains, have a workshop check the control unit
