Call your local MBCA (Mercedes-Benz Club of America) section and see if they have the name of the regional rep also. If you are a MBCA member, you can ask for assistance through the ombudsman program as well. I hope this helps. Lisa,

They have exhausted all their resources and can not figure it out. We are still having issues. It has been back to MB twice between July and October. Ken, I am sure that your 07 will not have the problems we have had with the 03. MB has most definetly taken care of this issue in the newer vehicles, which may be the problem with the technicians not knowing how to correct ours. Everything that they could have done, they apparently have done and we still have the issues. We are thinking about bringing it to another mechanic who works on the high end foreign cars to see if they can figure it out. Other than that we are very puzzled by these issues and MB's inability to pin point the issue. Thanks, Lisa Greg,

I have not experiened any problems like you described. If the problem has been identified by MB and there was a recall such as mentioned by Faisal, shouldn't your MB service department know about it?

Replacing the regulator with correct MB part no.; (Bosh) will solve the problem.

After I came in with the second battery having lost its charge, my tech did some research and came up with the fact that the voltage regulator on many of the 05 models, including the C Class (my C55) and SL Class cars with the 5.5 engine was some sort of non-Bosch brand, and that there had actually been a recall memo on them for the SLs. Apparently, the regulator would get confused and stop charging at 11.5 volts. Not good/ He replaced mine on my C class under warranty (which had three weeks left to run), and everything seems to be copacetic, now. Certainly have them check your voltage regulator output. Bet it's not uniform and may be constantly too low. I only have his word on the recall info, so don't know how much of that is factual, or the service memo number or whatever, but that could be your problem.

The dealership here has been unable to fix or diagnose the problem. It has been in the shop 4 times in the past 18 months. We are having the same issues with his 2003 SL55 AMG and would love to know if anyone else has been able to resolve the problem. Thanks, Lisa Richard:
