Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. The check engine light can come on for any number of reasons. It can be anything from a loose gas cap to a series of more serious problems. If the engine is running good then it shouldn't be anything too terrible. If you want to know what is going on then you need to know what the codes are in the computer. If you do not have a computer scan tool then you should have the computer scanned. Most auto parts stores will do this for free. If you can have this done then bring me the codes and I can tell you what is going on and what would need to be done to fix it.
