Here is an image of my boot wiring loom once I opened it I found that 8 wires needed repairing.

I was having problems with the following issues..

No reverse lamps
No interior boot lamps
Boot release not working correctly

I fixed all the wires using crimp terminals from maplins.

Bit of a common problem due to wear and tear on the hose and cables running through it. It is usually the brown cable that seems to break first.

I fixed mine last year with a new cable kit I bought on fleabay. The cable kit is made by GEWIE in Germany:

They do these for all sorts of Bimmers, as well as other makes of car. It takes a little while to fit, but it's an easy DIY and you end up with nice new cables and rubber hose. I've had no problems since doing it.

Wow how did you find them? That's a far better solution than the bodge job I just did lol... Thanks for the info.

Most people do it the way you've done, and as long as it works, it's ok.

I was doing a search about the boot wiring and and came across a US BMW forum (can't remember which one) on the subject where a chap from Denmark mentioned the GEWIE solution. I thought I'd try it and got mine from here:

It was, in simple terms: disconnect the battery, cut the old wiring off behind the carpeting inside the boot, thread the new cables through and connect and heat-shrink them. Do the same at the boot lid end, then sling out the old one. Reconnect the battery and test. Worked first time for me. It just takes a bit of time and patience hooking up the cables.

The instructions and colour coding for the cables is in German, but an online translation sorted that out. That reminds me, I did a write-up with photos on this I meant to finish off, with the GEWIE instructions roughly translated in English. I ought to finish it and post it on here.
