Err I wouldn’t even try it. For two reasons:
A hole not properly repaired (unless you are an expert how can you define?) may weaken or lead the tyre letting go at 90mph in the fast lane. Ever seen a blow out go badly wrong?
Secondly, what happens if they investigate the accident for cause and found that you tampered with the tyre (and concluded that you knew it was defective)?
If you look through the bumpf on the VW, it’ll probably have lots of disclaimers and I bet it isn’t a normal/stock tyre either (reinforced sidewalls?). Plus the emergency sealant kit (I have one incase of double-punctures) is designed for <50mph and drive straight to a tyre depot asap.
Experiment with something else!
