Hi guys

I have a 2005 B7 S4 Avant with a bit of an odd issue...

The main beam nearside headlight was doing odd things. It would flicker on and off, and then switch off for 5-10 seconds before coming back on as normal. No pattern - completely random.

So, I've replaced the bulb with a brand new one (Phillips or Osram, forget which), and now with 0 and 15 minutes of driving the warning light will come on the dashboard for that bulb.

The bulb is now rock solid (no flickering etc) - but the damned warning light is now causing the issue.

Any ideas at all as to what this could be???

Many thanks!

 

Know what the error says? "Dipped Headlight" by any chance? I've heard ballasts can go bad, since it doesn't seem like it is the bulb. Do you have the bi-xenon self-leveling headlights?

 

ballast is probably bad

 

Hi guys

It turned out to be a double-issue!

I replaced the headlight bulb which was flickering. That fixed that, but the headlight warning light was STILL coming on the dash!

Ran it thru Vag Com and it said there was a Daytime Running Light issue.

So, changed the bulb (even though it worked perfectly!) and hey presto - fixed!

Weird to have two bulbs go weird like that at the same time!!!
