Hi,the malfunction lights came on 2 weeks ago, indicating problems with ESP, BAS,and ABS, 3 Problems, it happened after finishing a conversation on a mobile while at the traffic lights, it has not come on again until now, but once i turn of the engine and restart, it does not come on.
Could it be some electrical glitches or something more that needs sorting out, car drives a1 and brakes work ok , any ideas thank you
