I have tried adjusting steering angle sensor (turned wheels lock to lock) to no avail. I have also cleared all codes using BavTech tool, and then error still pops up (the transfer case clutch position unknown errror). I can't recall if I've checked all the fuses. I think I have but I can re-recheck.
I think it may be that servo motor. Has anyone changed theirs? Can you get to it without removing the transfer case?
