Have Mercedes Questions? Ask a Mechanic for Answers ASAP
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.Any time the computer sees a system fault it will turn the CEL on and set and store a fault code. In order to determine what is causing the CEL to come on you need to scan the system again and retrieve the fault code and or codes . If you can get this done, post back with the results and I will advise you from there.
The code P2068 indicates a fuel level sensor B problem which usually means you have a failing sending unit in the tank. I find to reference to the code P20CC which in most cases means it s not valid.
Im not finding any reference to it so I have assume he is correct.
