Anyone know if "A Circuit" is referring to specifically one of the 4 speed sensors? Or is it something else entirely?
Cannot seem to find anything anywhere to help pinpoint where this fault code (P0500) is coming from..
get yourself a foxwell nt410 or something that can monitor the 4 wheel speeds. View the real time speed readings and youll see which sensor is at fault.

I have had both of my left wheel speed sensors go bad as have others, more than likely you have a bad speed sensor..

Thanks, sounds like I went too cheap on the scanner I bought!
yes, you are going to need a better scanner that can give you a more descriptive fault code or read out each wheel speed

Update: the more specific BMW code is 2B13, and apparently came from the right rear speed sensor. Replaced that, cleared the code, code is back again. Any thoughts? Something else that could cause the sensor to be unable to get a reading?
if its not the sensor, then the wheel bearing itself as it houses the magnet which triggers the wheel speed sensor.

May want to double check your connections and wire loom to make sure nothing is open.

Did you ever figure it out?

Yes the Answer was get a proper scanner or use ista to pinpoint the issue.

Pretty much. All sensors and wiring checked out at the shop, eventually determined it was a stored code that was not fully clearing from the system. Full reset to factory settings solved it.
