What are you reading it with to get those codes? That doesn't look like BMW codes.

Generic reader because I don't have access to any other method. I disconnected the JB4 so can't read it that way.

That makes it difficult. Sometimes the faults a generic reader pulls are nowhere close to the BMW code. For example thermostat faults are read as cruise control faults with some scanners I've seen. It might be a pain, but could you hook up the JB4? Otherwise it sounds like you would have to take it to a BMW shop.

I am getting the P15C8 code as well. I just replaced the right rear wheel speed sensor and now the left rear sensor seems to throwing the code.

Those are SAE DTCs. P15xx codes are related to P=powertrain, 1=BMW, 5=vehicle speed and idle control. unfortunately my book (Bentley) doesn't have your specific codes, it ends at P15B3.

Generic codes. . . Grab a dcan cable from a reputable vender, and buy either Protools, Carly for BMW, or MHD. All 3 great options and fairly cheap for diagnostics (I recommend protools)
