Hi theABS warning light came on tonight with message ESP not available. Does anyone know what this could be as I've just spent $5k on the balance shaft and a few other repairs and now this happens! Not happy
I had exactly that same error a while ago, after the battery had got a little low (several back-to-back short journeys after it and been standing for a while, plus SmartTop use for each journey too, during the summer)... after driving it for a few miles the error went away, and hasn't returned since.
Edit: If I remember correctly, I couldn't use cruise/speed limiter while I had the error too.
It could also be any one of the sensors which feed data to the ABS/ESP computer. As noted above, a session with STAR will clarify things. The lateral acceleration sensor and brake pedal sensor are common failure points and not terribly expensive to replace. I've had both go out on my C230; the brake pedal switch has gone out twice in the 15+ years I've owned the car.
