Hva betyr feilkoden?
The central electronic module (CEM) has logged an incorrect reading from the left xenon lamp. The fault may be caused by a defective control box for the lamp or a damaged control unit for the gas discharge lamp (GDL), since the control box supplies the lamp with the correct voltage and current.

- 3Look for looseness, corrosion and damage in the connectors to the control box
- 4Use a multimeter to check that the supply wire to the control box has voltage with the ignition on
- 5If the fault remains after these checks, have a workshop replace the left headlamp
