Well I got an E36 thinking all my worries would be halved (how wrong I was)
my car has now picked up a very strange electrical problem, every time I turn my lights off my dash stays illuminated my rear number plate lights stay on and the indicators go mental for about 20 mins, my handbrake light works but doesn't come on and if I open and close the boot a few times it all goes out but comes back on after 5 mins, I thought it may be a loose connection somewhere but its pretty much to the second every time


Any ideas lads I really don't want to go to the stealers to get it sorted



Cheers guys

I would check the wiring loom near the boot hinge, the wiring often breaks and shorts together. Pull the rubber protection off the loom and take a look, a good place to start.

Apparently on E36's with the on board computer, dodgy wiring here can even stop the thing from running by sending an errant command back to the OBC and spiking the OBC immobiliser - I find that a bit hard to believe but it's on good authority. The classic fault where you lock the door and it immediately unlocks itself is normally due to that. BMW do a new loom but in the past I've chopped a section of loom from another car and soldered it in behind the boot side trim. It's pretty obvious when the boot loom needs changing as it looks shagged. Unlike the E30/E34/E32 it doesn't plug into the main loom but is part of it..... :x
