Just bought a used 2003 A8L, never looked at interior lites during the day. Well I should have. Domes rear and front, floor don't work no matter what you do. Remote key doesn't activate lites. No warning chimes if lites are left on. Checked fuse, looks good. Talked to previous owner I found thru the nav system(always erase these!!) He said they were working as far as he knew before he traded it in. Had mirror work done, but that isn't directly connected to rear, chimes or floor? Help. Love car, but this is driving me nuts.[&o]
