Re blowing your engine. The powertrain covers you for 5yrs 60k, so no-one here with a mk7 is past the 5yrs anyway in that a 3rd party would kick in for such an extensive repair.. 3rd party is only going to say its for VW to repair under the powertrain warranty. Unless you're over the 5yrs 60k and maybe have a CPO up to 6yrs 72k. Where a very small number maybe approaching, then they may step up to the plate. So this is all a moot point anyway, if a 3rd party would cover. They'll fix a HPFP as that's not powertrain, or an ac compressor that's gone out.. and they'll do all that on the word of the dealer / indy.
