Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order to be able to try and help you with this issues I need to know what year your Mercedes is as well as the engine size. It would also be very useful if you could have them scan the system and see what the fault code is that should be setting when the warning light comes on.
