Mercedes: SBC control module, independent mechanic, sbc

Question
I read this code error (C21F7) What is the problem in my SBC and what should i do?

Answer
abdillahi,
There is not model year or chasis information on your message. HOwever, I searched this code and it is not in any of my data.
I suggest you contact a mercedes independent mechanic and ask about this code. It may be particular to the SBC on your car.
You may also want to visit www.benzworld.org and post your request to the forums.
Sorry I have no other information.
Good Luck
Rob
