Can anyone tell me how to test if the headlight levelling sensors are working, the headlights used to be constantly self levelling even when stationery but they are fixed but seem to be a bit low, any help much appreciated.

 

I suppose the easiest way is to disconnect the lower links of both front and back Sensor arms from the wishbones. Then move Sensor levers to a different position before engine start and see if the beam level changes. Probably easier with both left hand wheels off.

 

Thanks for that, I’ll have to try that when I get chance, I did notice that the plastic arm is cracked but doesn’t seem to be broken, yet “. On the front sensor.
