Hi don't know if anyones had tis prob but here goes, I let my mate drive my car round workks car park the other night and he stalled it when parking i then started the car up and reversed and it didn't sound healthy, the car then just switched off. I then treated the car as if the engine was flooded and it started fine. now it revs on its own and floods its own engine so it won't always start first time! Anyone got any idea's?
Likewise, I'm not that great with the working of a car/engines but could be to do with something like the throttle sensor? (if there is such a thing!) causing it to rev more than it should thinking the engine needs more fuel than is necessary?
C'mon chaps, help this poor bloke out...also tell me if I'm wrong!

Sounds like it could be the throttle position sensor, or the actator the other end - my mates Ka 
has roughly the same symptoms, and it was diagnosed as this.
Flooding like you're saying only occurs with carb cars, it's in the nature of how they work, and it can't happen to injected cars (this isn't to say that the symptoms aren't similar)
As the polo has a fly by wire throttle, and has it's air/fuel controlled by the ecu, it's very unlikely that it's overfueling - one way to check for this, is if there is a strong smell of petrol in your exhaust after trying to start...
The problems I can think of are ecu problems, sensor problems (timing, air/fuel etc, throttle position), crap fuel, blocked fuel filter/lines, or something might be wrong with the ignition (i.e. spark plugs, ignition leads, distributor etc).
Other than that i'm clutching at straws - someone will eventually know what it is... good luck, and don't let VW bend you over on the repairs

!Hopefully its a temporary thing caused by it stalling. Its adpative and if its been under much load at idle, it will have increased the mixture on its own, so when the loading isn't on it again its too rich. It should sort itself out after a bit of TLC. You could try removing the battery for a couple of hours. But you'll have to ask someone else how this works on the GTi, am not sure how to adapt the ECU to the throttle again, presumably you just drive it.
