Hello all, i have a 2002 ML500 which I have been having problems with the BAS/ESP warning light. I took the car to the dealer and the SDS returned codes C1000, C1042, C1022 and C1040. A new ESP/BAS control module was ordered and later installed. Fast forward one month. The light is back....intermitantly of course, about once a day after driving for a while. Took it back to the dealer today and when scaned with the SDS....no codes. Are there any faults that result in a code but get erased when the ignition is shut off? I love this truck but this is becoming a real hassle.
