It's limited but i'm sure it's more like 3,200 on the 2.0 TSI. I don't know the reason, maybe to stop you overheating the the turbo etc when at standstill?
Anyway, this is NORMAL! At least on the GT. If you had a petrol with revo fitted you wouldn't have stalled
2200 rev limit in neutral on a 170TDI sounds right, if it's 3200 on the 2.0TSI. The TDI is geared much higher and red lines much earlier than the TSI. With all the torque generated, the limiter is in there to stop you frying your clutch and tyres primarily. If you could attempt to pull away at 4000rpm, you'd shred through your tyres in no time, the car would have no traction, and you'd be wheel spinning on the spot.
Would you really want to pull away from a standstill at 4000 revs in anything other than an "Airfix" Corsa 1.2 and a section of oil pipeline pipe where the exhaust should be?
