There is at least 2 different threads on this forum (with multiple pages, mind you) of people complaining about the same thing. There is clearly something wrong with the transmission program in the '12's, and it doesn't take a rocket scientist (or PHD - no offense guys) to realize that VW changed the program from the '11's to shift earlier and stay in lower gears for better fuel economy (as they have been clearly marketing). Makes total sense actually. Unfortunately they probably didn't study this "tweak" long enough, and here we are today. If this wasn't the case then why would VW of Canada have already acknowledged the problem and be preparing to issue a TSB?? They would've told us all to piss off if they hadn't confirmed the problem for themselves
And regarding your comment about the "abundant low-end torque" of the 2.0... This isn't a 3L V6 we're talking about here, you know that right? Even still, there's not a 3L V6 on the planet w/o a 150-shot of N02 that has an "abundance of torque" at 1,200, especially a medium displacement 4-cylinder engine with a turbo choking up the exhaust. You do know what "spool" is, right?
So sit back, shut the fvck up, and keep driving your Tiguan the way it is until you rattle all the bolts loose from the engine bay... That way you can proudly say that you "fended off PCM updates because the car drives like it drove on the test drive!"
