awesome post Mujahid

Many thanks for this. I had same symptoms - front passenger door stopped working (sometimes at first then gradually not at all) with the remote and had to open it from inside but then wouldn't unlock from inside eventually.

Read your 'hot wire' post but also heeded your warning about not doing it unless confident. So I got a replacement (salvaged) module instead but it made no difference when I fitted it. Then wondered if it was the actuator that was faulty?

Anyway, plucked up the courage to try your hot-wire. Got it right second attempt when I realised it was the black AND the white wires together (not the black/white wire) and the blue. Spliced the 3 wires and fitted them to a terminal block (blue in one and the black and the white in the other) then used an electrical cable offcut to connect to the terminal block and then to 12 v power. Also used the big black connector to power it and.....voila! open sesame!

The remote still isn't working but at least the door opens from inside again. I think the salvaged module must have been faulty also.

Thanks a million :-)

Just a wee update peeps. Got a replacement module but it did not fix the fault so will have the actuator swapped over next. In the meantime have had power cable to actuator disconnected to prevent deadlocking again. Lock works fine manually.

My BMW specialist/indie mechanic friend was knocked out by Mujahid's hot wire trick.
