Simon, You need to read the DTCs stored in the Central Electronic Module (CEM) and Rear Electronic Module (REM) to see exactly what the problem is. As been suggested, it sounds like the CEM or REM has either sensed a problem with the voltage from the now not fitted Xnenon lights and/or an issue with the self leveling system (in the REM). The CEM (and possibly REM) will need to be reprogrammed so it now knows the Xenon lamps are no longer fitted. The CEM stores the configuration file for the car, i.e. what modules/options are fitted. You will need either the dealer or Autlogic to do this. HTH Sean
