Thanks M.B.DOC. To GVB: I am not getting any codes and the CEL is off. I replaced the air filter two weeks ago. This problem has occured since I bought it.

Now the second part of my question is where is the ECU located on this car? I want to check the part number before I take it to the dealer. With my old 190e, it was located behind the battery, along with the ABS controller. Is it in the same general location under the hood of my c280?
