On my BMW M6, if you put the car in neutral at speed and then pulled both paddle shifters back for 10-15 seconds, this would recalibrate the clutch.

Is there such a procedure on the Porsche PDK paddle shifters?

the m6 uses an smg system - 1 clutch

pdk utilizes 2 sets of clutch plates

so to answer your question, likely no

What is wrong with your PDK? Your dealer can download any program changes.

Nothing wrong with my PDK, its fine...

I was just asking this question thinking this might be a DIY "maintenance" type of thing once in a while...

Nope no need to do that and your PDK is very different than your BMW SMG.
