In my industrial experience, plastic fittings, plugs,etc are not suited to this type of application - you don't normally get any "feel" from the threads as you tighten up. Best if the mango-tree blacksmiths in these Stealerships actually learned what a torque wrench is for, and how to use it!
The second page of that same TSB was even more revealing. What the hell have these blighters been doing up till now, then? I think we know.........
It demonstrates the tragically low general levels of common sense and engineering practice in these dealerships that VW finds it necessary to issue a TSB to cover how to fill a car up with oil...... The correct procedure for that hasn't changed since cars were invented!
Perhaps I'm just an old cynic, though!
