A true nightmare if ever there was one. Who said they would love a white Xmas?
And be careful of the Accident Management Co. R32 will no doubt have a higher spot rate than a Gti (although I could be wrong-would have to check). You are entitled to a like for like replacement as this is a non fault incident but the third party insurers may kick off. Having said that, that should be the AMC's look out, they take the risk.
Sorry, I'm an Insurance Broker Claims Manager

ill shut up now.........
Hope you get the GTi back quickly pal.
