It's on due to the oil change. Oil change was made (not at dealer), but the CEL is still up. How do you reset it?

Thanks!

 

Do a search for resetting the maintenace page. I'm not exactly sure how to but I know its posted.

 

My CEL came on a while back and it ended up being a crack in a wiring harness. The light was shorting out b/c oil was getting into the pins of the connections. I had to get it checked out at the MB dealership to tell me this. Ended up being quite expensive to fix, but they covered it under warrenty.

Only way I know to check a warning code is go in to a mechanic who has a cpu to hook it up to. Then they can tell you what's up.

Good luck
