Evening all

Last week, my A4 told me the right rear light bulb needed replacing. Had a check and it appeared the inner bulb for the red rear lights was out (there is a single filament on the inside and dual filament that doubles as a brake on the outside). Got round to buying a bulb this morning, whipped the light out and the bulb was fine?? Replaced bulb anyway but still no luck.

Thos makes me think it is a wiring fault but I don't know where to start other than using the left side as a source and splicing a wire to the right light, but I guess this wont help the computer telling me there is a bulb out. Anyone else had a similar problem?

Sorry, should have explained better. The bulb works but not in that particular bulb socket. The contacts are all corrosion free too.

I had a similar issue like yours and it turned out the contacts on the bulb holder needed a bit more bending out to make better contact with the bulb..

I had a similar problem this year with a few of my rear bulbs not working. I even bought new bulb holders but it turned out to be a J519(I think) central control module. This part only comes from Audi and has to get coded to the car with vagcom. I had mine done at a local vag specialist and was about £375 all in. Hope this helps.
