I have noticed that my xenons are only lighting the road about 5 metres in front of my car. Driving on unlit roads has become a real problem. So I took the front and rear drivers side wheels off to check the auto levelling sensor arms. Unfortunately the front arm was hanging down. It seems the metal bracket that attaches the sensor arm has corroded and sheared off. So I need to source a replacement. I've looked on rimmers and it appears they only sell the sensor unit as a whole and want over £100! Does anyone know if you can just buy the arm and bracket?
