Thanks everyone for the info on this. My E60 4dr boot started not working intermittently for a few days and then stopped completely. Luckily I found this post and similar ones. Discovered that the brown wire in the harness running through the boot tube was broken...

Thank you all for this thread. I was also having locking issues on my 2008 528i, so I popped out the trunk side panel to check... The entire wiring harness appeared intact but after some close inspection the brown wire was completely broken in half. I am so glad to find this. I fixed my trunk release in less than 10 minutes start to finish.

Broken trunk release ground wire fix
I spliced in about 6" of spare brown 16/18 gauge copper wire that I had laying around in the garage. I used (2) 16-22AWG butt splice connectors to splice the wire in line and connect it on both ends and crimped them on with pliers. I then wrapped the connections with black electrical tape and then re-wrapped the wire bundle/harness so it looked semi-professional.
Here is a thing I mocked up to give you a better idea of the in-line splice: http://imgur.com/5fUrbjJ
If you don't already have this stuff laying around your house; butt connectors, electrical tape, and 12" of wire should run you about $5-10 at Lowes or Home Depot.

As far as you could tell, did the wires get pinched somewhere or did the insulation just bust open from fatigue?

Something I do find strange is that it seems to be the brown ground wire that is breaking in all of our cases; even though there are several wires in that harness/group. Maybe there was some type of quality control issue with that brown wire or coating from the factory?
