This is not necessarily true. VW will not warranty work that is completed by another company, or work that alters the manufacturer's specs on the vehicle. Just because somebody tunes an ECM doesn't quite make them a loyalist, but perhaps somebody who just wants to increase performance.
Not warranting work completed elsewhere is an industry standard in all retail markets, especially altering the vehicle. However, flashes and air intakes should not affect any warranty work unless the problem is deemed to be created by the work completed. I have not had any warranty work turned away for performance upgrades, even Brent's 1.8T Jetta that chewed through transmissions after his stage 2 upgrade!
Devon, best of luck with the upgrades!
