Have you tried another MB dealership? Bring it to another shop and have another mechanic to work on it.
this thread could help you with some ideas, seems like the guy has the same problem and it doesn't sound too uncommon

Just curious, they replaced your plug wires but not the plugs??? That's bad practice if it's the case. I guess it's a warranty job so they would replace as few parts as possible. If you are paying, they might recommend to you as well. |
