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. :?
Its' probably nothing if the messages reset themselves. Call your service dept. and explain what happened. If they think it is serious they'll have you come in. At least it'll be under warranty. Good luck.
It's nothing to worry about unless it keeps on coming on every time you start the car. I had this problem, and I happened off and on for a few months. My car has 13000 miles (got it in 11/01), and it has not done it recently ( last time was probably 4 months ago??... knock on wood). When the messages went on I didn't experience an difference with the car. The traction control was still activated ( im not sure about the BAS or ESP stability though). It usually happened when I drove on local streets, so I would just pull over, pull out the key, and restart. This reset everything.
The BAS/ESP fault is due to the ground wire connecting to the BAS/ESP module. It seems that the connectors keep poping out, that is why you are getting a malfunction.
MB told me that the connectors are going to be recalled. So you and every C230 coupe owner will get a recall notice in the near future.
My MB dealership is ISO 9001 certified, so they guys were throrough in their analysis.
I would bring your C230 in and get the BAS/ESP module replaced. Tell them your situation, so they can check out the problem and order the parts, otherwise you will be waiting a few weeks for them to come in from Germany. Its been 2 weeks and I am still waiting for the connectors.
