Hi everyone. Am having an issue with my 2006 E61 520d M Sport touring.
The right reversing light doesn't come on and I get a warning every time I start the car regarding right reversing light failure. There is nothing wrong with the bulb and the local BMW dealer said it is an issue with the wiring system in the rear somewhere which would have to be totally replaced, which costs a fortune...
Does anyone know of any DIY ways around this or is the replacement of the whole wiring loom the only way to go?

Alternatively, does anyone know if there is a way to disable the warning at engine start alone as that would be more than enough for my liking

Cheers!
Stan.

 

I think this might be related to a break in the tailgate wiring loom, which houses that wire, and there's a DIY for it. Do a search on the forums about it. Lots of posts.

 

Here is a link for it:

I fixed mine yesterday, the wire for that light is yellow and white. I have had 6 wires in total that have broke, wiper, wiper park signal, number plate light, reversing light, defroster and button for boot lid. I was going to change them all was my first plan but, they where a lot thinner than the ones that I bought so I decided just to chnage the one I found broken. So now I have done the operation 3 times instead :-(

 

Thanks for the link Robbie, much appreciated!
