Abs asr traction control and engine light
On a recent trip, all four lights came on after fueling up my 2016 Thor Synergy, Mercedes sprinter. It still drove fine but wasn’t able to use cruise control. The next day however, the engine went into limp mode, wouldn’t shift out of first gear. Luckily I was near a Mercedes van dealer. It turned out to be a wheel speed sensor. Mercedes had me back on the road within the hour, no charge, all covered under warranty. Appears to be a frequent problem with sprinter models. So get to a dealer as soon as the lights come on.
