I've only stalled this GTI once, and it was when I tried to take off in 3rd at a light when I first got the car.
The car itself is almost impossible to stall out of first. I think it's because of the electronic throttle which may give it more gas when the clutch is being let out. That's just me spitballing though.
I stalled the ms3 when I test drove it, started up a hill in 3rd by accident... I also stalled my gti once I wasn't thinking and didn't even realize the car was on since inside our cars are stealthy quiet. Let my foot off the clutch with the pb on (thank goodness) and just lurched forward a bit in my parking spot.
I have never stalled my gti, since it is a DSG, but in my last car, and all my other cars, I used to do it occasionally. It was usually when I was distracted, for instance, pulling into a parking spot, then reaching for my phone, and forgetting to put the damn thing in neutral before letting the clutch out. Good thing I always had my foot on the brake pedal, but it always still scared the hell outta me.
like 4 months ago... was waiting to make a left, reached back to grab something and accidentally pulled my foot off the clutch... a soft stall b/c other foot was on the brake. I don't even think the people behind noticed lol
