bmw door locks

Using a test light is quicker, faster and more efficient and if the truth were known, most techies and pros still use them! BUT you have to know where and when! I have a pal who uses a power probe, I'm too scared to get one. The 07 vehicle worries me, I'd have used a DB-ALL or similar for locks, lights and door triggers.

But the dB-All isn't supported for the 07 X3...? At least not in the US. You think the BCM might be the same? I could try it and see what happens...No question is stupid or not worth asking. You were once a noob, right? :)

Yes, go to Xpresskit, top right, click on US, you'll get regions on top left, select Europe, then do the usual, you'll still need a "key in a box" though.

Oops, not listed, I'm uploading the Directwire info right now, I'd either probe the wires at the lock or hit on the motor wires at the "general module" (5 wire).

Go to Downloads/Manuals, key in BMW X3.

Well, I have 4 different diagrams. All but one tell me it's the yellow/red wire from the switch, and for both lock and unlock. The other says the WHITE/ black and the blue/red. I have probed the wires at the driver's door lock, and found two that 'spike' to 12V, depending on lock or unlock, and they rest at gnd. The X3 also has the two step unlock (first time drivers, second time the other doors) from the key hole in the driver's door. I was hoping I could leverage this, since the factory remotes don't work. The locks will begin to move slowly if I attach +12V on them, but will eventually blow a fuse (I've only went up to 20A, but I think the fuse in the box is 30A).No question is stupid or not worth asking. You were once a noob, right? :)

Going to the switch won't give you comfort close. Either probe all the wires going into the door, not the twisted pair or check at the window switch in the door; what you found are the motor wires.
