Hello,
New to all this so apologies in advance if this problem has been talked about before.
I have a 2006 w203 c180k and the engine light came on and the revs started to “pulse” when stationary in drive so took it to a local garage.
Engine codes came up with MAF & breather pipe. On inspection, breather looked new so just changed MAF.
Engine light was still on so checked and found the Lambda sensor was at fault and changed it.
Engine light was still on so they changed the breather pipe BUT the engine light is still on and this time with no codes on the machine.
Mechanics have checked over the electrics and fuel system and can’t find any faults and they don’t know what they can do and apparently the revving is still happening but not as bad.
I am stuck as the MOT is due and booked it into a merc specialist. Has anyone had the same problem or some advice what it is??
properly frustrating!!!!

Here in the USA the engine light can also point to transmission trouble. Any issue that can affect L/km. I think the shop didn't have a good code reader.

^^^ What he said! ^^^ (y)

They must use a Mercedes savvy device that can read all modules. I guarantee that if the CEL is on, there are codes. They just cant read them with their tool.
