car brakes too right side and esp/bas light comes on
The bas esp and engine light is on cruise control does not work loss of power
Just replace the brake light switch. It's a pain to do but with patience it solves the problem.
BAS ESP light comes on and stays on for 10 to 20 minutes then clears. It happens every few days and sometimes stays off for longer periods. I first noticed it after a service at my mechanic and he said I should ignor it and it will go away.
ASR idiot light comes on, cruise control stops working, brake light switch near brake pedal failed.
