Hi Guys this is my first post here.
I have the E46 318 like the title says and the boot button has stopped working. I understand this is a common fault, and the main cause which is broken wiring in the rubber gromet which I have checked and not found a problem with. I have removed the complete boot lip complete with number plate lights etc and found a little rust on the connections but nothing else. I tested the microswitch and I got sometime like 3.2volts and when pressed it goes down to 0.4volts. Not sure if this is correct or not. has anyone got any pointers they would like to share.
