Next Up - Troubleshooting my PDC

[garrett.fell]

So here's my next mini-project. Restoring the PDC to operation.

Here's what I've got. Under most circumstances as soon as I throw it in reverse I get a beeping sound and flashing PDC light by the gear shifter. I press the PDC button and it shuts up. This is getting a little old so it's time to fix it.

I've read about "listening" for a ticking to figure out which one is bad, but I don't hear any ticking at all. Is this to be done with the ignition in a certain position or with the car running?

BMW scanner 1.4 seems to be telling me it's the front right, but there are two front right ones really. There's front-front-right and front-right-right. Listening for an audible click would help, but I hear no clicking from any of them.
