Esp warning light on
esp and bas malfunction lights come on at will, then reset when car shut off. Sometimes, this does not happen for weeks, then almost everyday, then is stops again for long periods.
I had the BAS, ESP lights come on. Cruise had stopped working, also sometimes the car had stopped shifting gears when in drive, it would take a a few seconds after being put into drive for the throttle to kick in. And finally it used to jerk sometimes right after engaging into reverse or drive.
The culprit for all this was the brake (stop) light switch. A simple enough replacement, not that expensive and everything seems to be fine now!
Your friendly dealer should be able to take care of it for you. Mine charged me 80 bucks. But if you want to do it yourself use this https://www.youtube.com/watch?v=AWjIZBuPLZ0

ABS, ESP, BAS warning lights come on constantly, car goes in to limp mode. ABS module has been replaced twice. Still having the same problem. Bought the car new in 2001 C240. It's been a lemon.
