To turn off the check engine light(CEL),you must clear the diagnostic trouble code (DTC).This can be done with a scan tool.If you do not have a scan tool,you can disconnect the NEGATIVE battery terminal.Do this for a minimum of 20 minutes to clear the keep alive memory (KAM).Reconnect the battery terminal.If the CEL comes back on again,you have not fixed the problem,or another problem has cropped up,requiring a scan tool to see what DTC has set.

Hi there,i have a c200 elegance 2005,i seem to be having problem after problem and my pride and joy is becoming a money pit!! well here goes,it wont rev past 3000 revs, i was told this would be the mass...


You must be having a check engine light or maintenance coming up on the dashboard, if yes the best way to start troubleshooting this problem is to run a diagnostic test on the vehicle.Also after changing the mass air flow meter did you reset the ECM ?If not then this is required after any repair you do.Hope this helps.

Air flow meter


The turbo uses a completely different air flow meter than the non-turbo.

Pulling the fuel hose off and checking that way is ineffective as there is no pressure on the pump so you need to put an in line fuel pressure gauge to be 100% sure you have operational pressure.Have you got a pulse at the injectors?You will need to plug in a noid light tester to determine if the pulse is good and exists.You could spray engine start up the intake before the air flow meter and see if it wants to run.If it trys to run then its likely a fault in the fuel system.Im assuming that the other repairs were done correctly.
