C32 AMG ESP

I got the ESP error fall of 2013 then I stored the car for the winter.

I took the car out of storage in April and I've been driving it ever since. Then yesterday I go to start my car and I have the ESP and a CEL at the same time.

P0120 and P0221.

Is it a big problem? The car hunts on idle then other times it idles perfect. I also have no response with my pedal but if I restart the car it works but plays in and out of limp mode. Any information on this problem?

This sounds like a problem with the accelerator pedal, there is an electronic box inside that intermittently fails with the same symptoms you are having. Causing ESP errors and limp mode

Sounds like engine wire harness.
Will mess up communication between ECU, TB, ESP, TP. You will get all sorts of errors even replacing the above items.

We're all just guessing.. what more do you want? a definitive answer to a problem none of us have physically seen in person? Try changing the accelerator pedal (its not very expensive afaik) if that doesn't work... move on to something else.. It's all guesses unless you get star diagnosis.

If it's the engine harness, Star will not pick it up, it will lead you to wild goose chase.
I've tried it. But you should try the cheapest item first, gas pedal is a good start.

agreed, the star scanner will not spit out: engine harness <-- this is your problem.
any good technician will know when a scanner is throwing them through a loop.
