One clutch is always fully "disengaged" with no clutch plate contact, a slipping clutch is just starting to bite (friction plates just making contact ) and this "slipping" causes heat and wear until fully engaged, typically as in when a car is sitting in drive but not moving, or when it initially moves off from a standstill or is ins slow moving traffic, so the main victim for this wear is the clutch on 1,3,5 &7 shaft, iirc thus overheating was the cause of the many early DSG failures, and there were lots of them.

Normally leave it on, stops car slipping (DSG) clutch when stopped.

You need the front facing camera mounted in front of the rear view mirror. Sounds like you don't have it.

😬Got it fitted, excellent, think it uses the GPS to identify cars location so does not use full beam in town. You activate the auto main beam by pushing the headlamp stalk forwards, activation confirmed by white headlight symbol in dash. It's better than manual control, it never looks away to fiddle with the radio, talk to passengers or adjust the multitude of driver aids, Use t always.
