Hi Guys Please help. Im a technical guy and i do mercedes benz key programming. My problem is i've to a C240, w203 and i damaged the EIS and ESL. Now i recently found a complete Lockset for a 200 Kompressor. So i only need to use the ESL, EIS and the key from the 200 kompressor lockset onto the C240. Now, how do i match the ECU from the 240 to work with the other stuff

How did you manage to damage the eis and esl?
you need to make the ECU virgin

Not sure on how to make it virgin but you can go to http://www.mercedesecm.com/c240-ecm.html and they can program an ecu for Mercedes c240 to work with your VIN and keys.
