Plese Help....

I have just fitted a pair of xenon headlights from another Audi and all the lights work fine (indicator, sidelights,main beam) but the dip beam (the one you drive at night with) does not seem to work on the passengers side. The driver side is woking fine. I orderd a pair of DS1 bulbs which is currently working in one of the lights but not the other.

I wouldappreciate if anyone has any tips, THX

 

Are you using bi-xenon lights? A4s use D2S bulbs for the dip, low beam.
