Hi all, hopefully some one can help.
I’m having problems with the upper lid opening on its own at random. The handle wasnt working so I opened it up and tried to clean the little sensors but managed to completely break them, so I just took them out and relied on the key fob or inside switch to open the boot. It was fine like this for a couple of months and now the upper lid just opens randomly, even when driving it just unlocks, hit a bump and then it locks again. I looked up on RealOEM and it gave me the part number and decsription for the sky blue relays so I bought two new ones but when trying to put them in they spark and blow the fuse. It was the purple relays that are in and when I take the fuse out for the upper lid I can hear it clicking away, obviously this would be the upper boot lid opening.
Thoughts ideas anyone?
Thanks, Sean.

You have a short in the wiring somewhere. That's is why you have a spark when you plugged in the relays and why the fuse blew out. That could also be why the trunk pops open when you hit a bump.

Thanks for the reply.
The lid locks when hitting bumps, it opens randomly when stationary.
I’ve read about the wireing and not a job I want to tackle, is there a reletively easy way to check the wireing?

I should also state that its a 2006 N62 that I have, if that happens to make a difference in anyway.

Did you replace the tailgate button? mine was going bad, then went completely dead but sometimes when I turned the car off, it would open the tailgate. Changed the handle assembly (with the switch and plate lights) and now its back to normal.

Havent done anything with the button, waiting on new rear handle assembly coming. I’m wondering if because I broke all the micro switches in the handle when I tried to clean it, if thats whats now causing it to open randomly.

It could very well be it... You'll have to wait for the handle assembly to know.

Replaced handle assembly and all seems to be good, no more lid opening on its own!!
