Probably one of the 2 sensors on the throttle pedal itself from the sounds of it. Do you have the actual code number or full description of the fault code?
Edit: If you have vagcom then you can check the values of the 2 sensors in group 62 of the "engine" module. The 2 sensors both have different ranges.... The one in "box 3" reads between approx 10%-98% (according to how far you have the pedal pressed) The one in box 4 only reads in the range of 5%-49% (49% being pedal to the floor)
The sensor shown in "box 3" of group 62, should be approx twice the value of the one shown in "box 4". Also they should both change evenly, and at the same rate, as you press down on the pedal. So for example, if "box 4" is showing 25%, then "box 3" should be showing 50%.
Hope that makes sense and is some use to you buddy.
