Hi all, new to the forum but looks like this is the place for S6 info and/or help!
Had a couple of (hopefully simple) questions about my 2007 S6. First off, i was wondering if anyone knows how to manually adjust the headlights. Meaning adjust the beam height or vertical adjustment. I have the xenons with integrated fog lights and the adaptive function (beams turn with your steering wheel).
I’ve done some browsing for info but a lot of it seems confusing or more model specific to the A6. When I pop my hood I see two white, hex style adjustment screws on the headlight assemblies. One closer to the front of the car, one closer to the rear. I’m very familiar with VAG-COM and have a hex-can cable so I can put the car into learning mode and all that good stuff but I’m not sure which screw is for the height/vertical adjustment. Hoping someone has done this before I go down the trial-and-error route.
My second question is about an issue that seems to be somewhat common on the earlier C6 models (as far as I could tell), but not a lot of info on it. Anyway, the issue is that sometimes (maybe once every 4 months) the car will not start. The push button start does nothing (no cranking, no sound, nothing) and using the physical key does nothing. The MMI does come on, but no other dash lights. After the first time this happened I did some code scanning with my VAG-COM and found a circuit fault in module 05 “Acc/Start Auth.” I don’t recall the code off the top of my head, but I’m sure I have the code saved somewhere. Anyway, after resetting the fault the car starts up without any issues.
I did some searching on this issue about 6 months back or so but could only really find that people claim it’s some transponder problem that is inside the steering column and the whole column needs to be replaced. After looking at the price for a new steering column I decided to just toss an old laptop into my trunk along with my vagcom cable instead, lol. Has anyone encountered this and maybe knows a workaround instead of just replacing the whole column?
Thanks!
