Who are you insured with?
Some insurance companies, I know Brentacre do this, won't charge you any extra on your premium for most mod's and, with proof of purchase, will replace any of these parts in the event of them being damaged in an accident etc.
I'm certain as long as you notify them along with receipts, they will replace it for exactly the same when or if the time comes.
They're even pretty lenient with tuning. They will give you a certain horse power limit, again, without your premium going sky high!
....And a VW specialist..!
