    Hi guys

    I have a 2005 B6 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!

    Hi guys

    Sorry I screwed up. It's a B7 not B6. I'm going to re-post this in the B7 section.

    Sorry guys!!!

    Hi there

    I don't think they are self-levelling, but it has Daytime Running Lights.

    Oh, and bi-xenon. Takes D1S bulbs for main beam.

    Shall I move this to the B7 forum?

    That reads like your DRL bulb has gone.

    Take it you've actually cleared the fault 1st & cycled ignition & scanned again when car running & drl's/headlights on?

    If so then check the contacts for any corrosion 1st, try swapping bulbs around L to R etc.
