Electrical Help!

[tomhunt85]

I've got a problem with my headlights and backlighting on the dash not working. They have randomly come on once or twice when it's been raining as though that's affecting it but only for a few seconds. Spoke to a friend who used to work for Audi and he reckons it's the grounding. Anyone know where would be best to start looking or have any other ideas or solutions?

Just my luck I've got the MOT next week as well lol.

Bump! Come on, need to find out if there's any grounding points that aren't that obvious?.... Anyone?

Theres grounding point behind each headlight iirc, they'll probably need to come out to get to them. Checked all fuses? Bad connections?

 

[tomhunt85]

All fuses are fine mate, can't see any dodgy connections either. It started with just my dash lighting not working. Then the rear lights stopped but fogs, reverse and indicator still work. Then a few days later the headlights stopped working? Didn't know whether it was a loom or wiring problem.

Cheers for the info

Hmm could be a possible UCH problem as well if its effecting all of those.

^^agree, I had some intermittant problems with my electric window. Since it went into renault for other reasons and they had to reset the UCH its been fine *touches wood*.

What's the UCH?

 

[bmh.01]

Black box in the passenger footwell under the dash, controls pretty much all the auxillary electrical systems. Can go wrong and won't be cheap to fix.

I think it was £80 for the diags on my xenons, since it went in the windows have been fine. I didn't let Renault replace the ballasts as they wanted £600 so I replaced them myself at a cost of £250.
