We had a thread about this but I can't remember what it was called. You can see it in measuring blocks in the ECU though. The switch needs to be completely compressed when the pedal is on the stop, and then be released as soon as the pedal is touched.

Great, thanks for that. I only have VCDS-Lite so not sure if I have access but I'll have a look at the sensor itself and adjust.
