Heads up for TD1 flagged members in the GTA (that's Greater Toronto Area for those not from the region).
My '10 GTI threw the ever so common P02015 code. I took it to Mississauga VW and Georgetown VW (G-town being the dealership that originally loaded the APR Stage 1 tune on my car), both did their diagnostics and confirmed the intake manifold failure. But VW Canada and Georgetown VW will NOT honour the extended warranty on the intake manifold due to the APR tune. Even though it was Georgetown VW that originally did the freakin' tune. The invoice was on VW stationary with their information. The G-town VW tech that did the tune assured me that VW wouldn't have any issues with it. Or I might have had second thoughts about getting the tune in the first place. Jump ahead a few years, a notoriously unreliable part fails on my car that has nothing to do with the tune, but G-town VW now backs away. They say it's not their responsibility and will not stand behind their work. Tough luck to me.

Hope you guys have better luck with your VW dealerships. A new intake manifold is less than $300 and I can install it in a couple of hours in my garage. But that's not the point. It's the principle behind a dealership that will take your money and lie to you when getting paid, but will turn the other way and not honour or stand behind their work. In retrospect, the thought that both Mississauga VW and Georgetown VW actually tried to sell me a new VW when I was in for previous services is disappointment and borderline offensive. I almost even fell for the sales pitch. But this will be my last VW me thinks.
