S5 TPS ? which is which
Standing in front of the car facing the engine, Which sensor is the narrow range and which is the full range.
Here is the problem I have two TPS's one with a bad narrow one with a bad full according to the codes my car throws.

You can tell by looking at the cams that move the TPS plungers.
The long range plunger rides on a spiral cam.
The short range plunger is pushed in by an arm on the throttle shaft.

the narrow-range is closer to the front of the car. the little actuator arm loses contact with it at a certain opening point (hence narrow-range) while the other one (described by sureshot as "spiral cam") continues to wide open throttle (hence: full-range).
