Before you go throwing parts at it here is some info you may not know.
The gas pedal position pot is a dual potientiometer that the DME uses for throttle control and feedback from the second pot.
There is also a dual pot inside the throttle body. The DME compares the voltage reading of both, if they don't agree you get the error you have.
When you replace these parts they need to be calibrated (GT-1 or MoDic) so the DME knows what's what.
I have got the some of the same codes for the pedal position pot in the past.
I popped off the side cover on the throttle body and sprayed the pot with volume control cleaner. Haven't had the problem since.
I spoke to the BMW shop foreman about this problem, he said that it can sometimes occur if you mash the gas pedal to the floor real quick.
The pot is under the clock spring.
