E60 520d Rear Lights

During the last week, the warning light indicating that a rear foglight has gone came on intermittently. Today I embarked on a 300-mile drive and, over about 200 miles, the rear right cluster bulbs went one by one. Fog, side, brake, turn, reversing. So eventually I had no lights in that cluster. This sounds odd to me. Do I buy a full set of replacement bulbs and fit them or is there some more sinister problem here? Anyone experienced this before?

Sounds like a short or something. I'd get it checked.

Cheers. Sounds like a call to BMW this morning then! Better get my wallet out....

A cheaper option would be to replace all the bulbs and see if they all pop again... just sayin because that would cost sub £20, whereas an hour of BMW tech is like £100 to start with. I'm also sure that a normal auto electrician/indy would be able to have a decent stab at it, rather than BMW. So could potentially save you from BMW labour rates, unless you have money to burn that is.

Interestingly it now appears that the bulbs haven't blown. I switched on yesterday and the rear indicator flashed twice when I tried it then said the bulb had gone. It's some other electrical fault. It's going in to BMW for another issue (ongoing with engine warning light since two years ago so they'll be paying) so just asked them to look at lights too. Sounds like I do indeed have money to burn!
