So, when the CEL reported trouble after you replaced the MAF sensor, what was the trouble code? It may very well be a different problem.

8 years old is kind of middle aged for most cars today, particularly a Mercedes. It is a bit unusual for anyone, particularly a Mercedes owner, to be doing their own repairs and troubleshooting. You have a fine pedigree vehicle that seems to me to be just starting to show its age. What could be next, almost anything or nothing.

ACTUALLY...YES THE CAR HAS BEEN A REALLY GREAT CAR...NO COMPLAINTS TILL NOW..AFTER HAVING OWNED A CORVETTE THAT GAVE ME SENSOR PROBLEMS EVERY WEEK ...I LEARNED THAT ITS BETTER TO KNOW WHAT THE CODES ARE TELLING YOU BEFORE YOU TAKE IT TO A DEALER WHERE THEY CHARGE YOU FOR THINGS IT DOESNT REALLY NEED.. THANKS

Soooo,

If you interrogate the car today, what trouble codes does it give you?
