The dealer sounds clueless. I used to work for Bosch who designed the Mercedes KE-Jetronic Emissions System and there are several routine things that wear out, like Oxygen Sensors ( $200 ) etc, etc. What is the code that is setting the Check Engine Light. if I knew that, I could help you with your problem. I have and do work on lots of Mercedes Emissions problems. I do Gold Shield Emissions work in N CA. where the State pays me to solve tough Emissions issues for people so they can get their car to pass the Emission Test and get registered.
