A little help please
Got "check engine" light. No messages to explain any faults. Car seems to be running properly. Oil level is good. Any other place to check? or go to the dealer.



It was done on mine and everything seems ok. If it does not correct the problem, the source of trouble is then "pins" of a connector.
The problem is reported and known by Mercedes and frequent on M177 engines.
