Power Trunk

Hello I'm new to the forum and I have a 99 528i. My power trunk does not operate I can open it with the key but the button in the door jamb does not work. I have read the fuse diagram in the glove box but their are other fuses in the trunk that I have no diagram for. Any help would be greatly appriciated.

Best place to start is check all the fuses. One fuse may be tied in to the door looks but not be listed. Also fuses may appear okay but actually be dead. Best also is to check them with a multimeter. If all the fuses check out okay, take a look at the wiring loom that comes into the trunk by the hinge. Sometimes they get frayed and short out.

I had exactly the same problem with my '98 528i from 3 years ago when I bought it. Did the usuals like checking fuses etc, no joy. However, yesterday, in a moment of brilliance I stumbled on a similar thread which also mentioned checking the wiring, so I did. The rubber concertina (sp?) that leaves the car above the boot (trunk) and enters the bootlid contained 3 snapped wires.
£5 later on wire connectors, I now have remote boot opening, a boot internal light, a boot that now opens from the drivers seat button and a big smile on my face!
Thanks very much!
Next job is to get the ABS/DSC light off (ABS sensor on order as old one was very tired looking) and PDC to work. They currently beep for a while when you put the car into reverse but then will happily let you reverse into stuff without so much as a squeak!
Thanks again and keep up the good work!
