I got message to service Stability Control system. TC light and abs light came on and stayed on until I restarted the car. After a mile or two the message again. The car ran ok but next day nothing happened. When I first got the car the tc light came on and the car would not accelerate. Had to tow to a garage. This happened two more times 3 months later. The car has 127,000 miles. V8

Code 0208 comes up but does not seem to be affecting the sprinters performance. It is however keeping the engine light on preventing me from getting it inspected...

rough and surging idle. tried shutting off and restarting and same issue. drove home 9 mi in reduced performance mode (30mph max on flats, slower on uphills). tried to troubleshoot but started fine and ran fine. code was stored but not currently flagging. going to wait until it happens again and try to scan when it happens. not a vacuum leak, i checked everywhere for one and there isn't one. pulling codes confirmed the lack of vacuum leak codes.


Mill light coming on drive ok

code check only
