The issue is it's f*cking shit design. When driving the car will lose power if you pump the pedal it will pick up again, also sometimes when starting the car the revs will go up to 1.5k and sit there. Turning the ignition off and on again sometimes sorts it.

I'm not sure but the below is how I understand it.
Not sure about the GTI ones but I think the HDI ones are a bit more complex because it's the sole control over the throttle. By that I mean the GTI still has a physical link to the throttle butterfly and the TPS is for the ECU to know what the butterfly is doing but with the HDI are fully throttle by wire. There are two circuits, one is the main and the other as a check. When they don't correspond there is a fault logged and the car drives like shit.
Nail, have you taken a GTI one apart? I was wondering if they are just a wiper on a track? The HDI ones are two magnets passing over two coils.
