Bi-Xenon headlights not dipping after adjustment

[rcg412]

Hello:

In my 2003 996 C2, with factory installed bi-xenon headlights.

Yesterday I adjusted the vertical adjustment on my left beam as it was too high - pain to do, pulled out assembly and did it that way.

All was easy enough, but when I put the assembly back in and did the bi-xenon dip test (light switch on, then turn on ignition), only the right headlight dips, the remedied left does not. :huh:

Any ideas? I read one post where there is a high voltage wire which could get snagged... Any help much appreciated. Thanks, Ross

Probably a bad contact in the connector on the rear of the unit, pull the unit out and check the pins for damage or bad contact.

You've probably solved the problem by now, but it's the placement of the wire so that it loops to the outside of the car. If it loops inside, the auto leveling won't work.

rcq412 - did you solve your problem,? if so, what was the fix

zegypt - I'm having the same problem on my car after removing and reinstalling the headlight assembly. Can you give more detail on "it's the placement of the wire so that it loops to the outside of the car. If it loops inside, the auto leveling won't work. " I'm not sure what wire you do you mean the wiring harness ? My car is a Canadain car with factory day time running lights, not sure if that is important or not

Thanks
