C230 Check Engine light stays on - PeachParts Mercedes-Benz Forum

The Check Engine light on my 1997 C230 came on, so I took it to the dealer, who performed some tests and recommended that I change the air mass flow meter. They "think" this will solve the problem.
My questions are:
What other failures could cause the Check Engine light to stay on?
How can I be certain that the air mass flow meter is in fact defective?

if they performed some tests,then they are probably correct seeing as how this is common problem with these cars about every 80k mls.

Any thing that ever comes up as being defective or suspected as being defective will cause that beautiful light to come on and stay on until you get the code cleared either by dealer or indy mechanic. If u took it to the dealer and they said its the MAF....u might as well do it. Don't worry I'm on my 3rd MAF in the last 8 years. Paid $900 from Mercedes Canada for the first one......and got the last one for really cheap from Auto House Arizona...like $300 something. Just buy it and swap it out ur self, its that easy.
