Question about 2005 Mercedes-Benz Mercedes Benz CL500
Mileage 44,000 I have a check engine light that keeps coming on and going out. Every time I am about to take it in for service the light goes out and the car continues to run fine. If my car runs fine and the light is out why would I take it in when I know they are going to charge me regardless.
Check 02 sensor--not a big problem

Might be a defective trans control module,have seen stored codes for this that will when current,set a check engine light-have them check for any stored codes and to check the fault frequency of these faults,the one with the mose frequency is most likely you cause,usually a check engine light will still set a stored code in "ME control unit" even though the light has gone out-

Have had similar problems with a 2001 C320. Turned out to be the fuel cap wasn't put on correctly. The fuel cap alignment is a little tricky, and sometimes requires adjustment of the locking mechanism.

I know the problem there is a car sensor in your Vechial that is bad it is near the engunie. Thats what triggers off. This happen to me and the guy go this thing that he pluged it in fuze box. Yes that means that there are errors you should take the vechail to a Mercedes Benz Dealer tell them that this the problem. Tell them if you guys could use the computer to correct any errors and can you check my Electrinc system sensor to make sure that is okay because that does trigger it off.

Your car has many systems on board, that require monitoring. All sensors need to be operating. Having your own code reader is a nice tool to diagnose this kind of problem. The code readers that are available today are hand held and plug right into the OBD2 computer link inside your car. You scan your car yourself and retrieve the error codes. The scanners usually come with a chart that lists the codes and their respective components.
