At throttle peddle (on some models at throttle cable end in engine bay, same item though, early use carbon pots, later
has 2 (electronic) pots together (forgot the proper name, age)
1 is a redundancy saver

On your W210 the potentiometer seems to be at the engine bay. Integrated to the gas pedal on later models:

That code is telling you that the throttle cable/ switch needs adjustment
