S4 b8 self levelling lights problem

Who did you buy the car from?
 
Third party dealer. Not sure if it's ok to mention they name?

I think you already have done that by showing their courtesy car :icon thumright:
 
True. Forgotten about it

Think we bought from the same dealer on that basis.
 
Neither of my headlights on my A4 B8 are moving and the sensor looks like it is fine. However moving it doesn’t affect the headlights at all. Any suggestions?
