I need some help determining the root cause of some warning lights. I have a 2006 330i sedan, auto trans. I have the following warning lights illuminated: Stability Control, Yellow Handbrake light and Tire Pressure light. The ABS light is NOT illuminated. My cruise control is NOT functioning, it gives an error when I try to use. My wipers, turn signals and everything else on stalk and steering wheel work fine. Checked all fuses, none were bad. I replaced the right rear wheel speed sensor, did not fix issue. I removed the SAS unit and cleaned the code disk and optical sensor, did not fix issue. I hooked car up to INPA and DIS to recalibrate SAS but I get errors (one saying something about a wheel balancer and another saying it cannot communicate with DSC module). Thinking my DSC module died, I took car out in the snow and tested the ABS. The ABS works. The SAS and DSC modules are super expensive so I don’t want to spend a ton of money on guesses. Has anyone had this issue and been able to successfully resolve? Thanks!

Do you have a cable to your car? It can be really easy to diagnose using it instead of guessing.

I have a cable and have tried to read the error codes with INPA and DIS and only one is coming up (5E40)?

Tool32 is your friend. Try the steering angle recalibration in tool32 (Google procedure, i posted it so many times on here). If it succeeds with the job then DSC module is not fried.

Ok, I will give it a shot. Thanks!
