BAS/ESP Light keeps coming on and it says visit workshop. I put on the scanner and it says these codes

C1332-
C1200-
C1504-
C1406-


I can not turn on or the ESP! What parts do I need and what will it cost? Is this anything serious?

C1200 is the easiest....brake lamp switch

C1504 is for re-initialization of the steering angle sensor. Turn steering wheel from lock to lock.

C1332 is for a BAS release switch on the booster(not replaceable)..can set that code due to bad brake lamp switch.

C1406 is also for the other sensor on the brake booster. IF the brake lamp switch doesn't fix that code, a new sensor on the booster should.

My 210 showed the same BAS codes when there was a bad connection at the BAS sensor connector. Just cleaned it up and no more codes. I can't take credit for finding the problem. The dealer tech found it rather quickly.
