How to reset 2002 Mercedes C240 service due dates

 

Hello and welcome to the forum! To reset the service codes, you would either need to take it to a mechanic, who will use their scan tool to do so. If you have your own scan tool/code reader, you're able to reset them yourself. The tool is a good option to have - it will let you read error codes and alert you to where possible issues are coming from. I've attached a link to a great scan tool for your Mercedes, please let us know if you have any other questions.
