At least I thing so. I have to change my brake pads soon so I will report if I was successful.
After a longer period of forgetting, here are my results:
Because I have a 320d touring "only", I haven't those two-phase sensors, but the simple one (just a single wire), even only one per axle.
I had it wear already, so here was no soldering option and I had to buy a new one as others.
