I was at the bank in the drive thru and then all of a sudden on the display says ESP malfunction then it blinks over to BAS malfunction and then it repeatedly went back and forth on ESP and BAS then when i turned my car off then turned it back on it stopped and never came on again. The transmission was in Park the whole time. What happened? Should i hurry and visit the MB shop ASAP or do i just wait till my Service A is due which is in 3000 miles. :?
