Your supposed to get free punctures repairs for the life of your car from vw dealers. Have you asked?
That's the first I've heard 
That's only if you bought some dealer Bullsh!t package. They tried to flog me it but I can't recall the name.
Punctures are fine to repair, location permitting, have probably had over two dozen repairs during my commuting days and only ever had one leak. I had a roofing bolt go through my 19" Pirelli about 1000 miles in. Still fine now, fitter did a brilliant job.
