There is an obvious issue with the actuator motors and transfer cases of the X drive BMW's. I am looking for a transfer case for a 2007 X3 and if anyone knows a reputable place for a rebuilt one, great. No desire to buy used since it will likely suffer the same fate. Actuator motor already repaired a few years back, now replaced but still the same set of 3 warning lights. We got the codes and a new TC is what is needed.
