I'm not sure if this is normal or not but most of the time my car tics over nicely at around 800revs and at the odd times if I pull up at the traffic lights or i'n traffic it will tick over normally then randomly it will raise it's revs to around 900-950 some times it stay like this over times it will do it for a couple of seconds

Also I've realised some times when I first start the car it revs up then drops to normal tick over or if it's been funny tics over at 900-950 revs

Is this a sticking choke ? Or a possible maf fault

Or is this normal with the cold weather

Thanks i'n advance

Hum that is strange, I can't remember off the top of my head what my TDI idles at but it sure doesn't go up when stationary! Not sure why it would be a MAF fault, it could be all sorts of things, for example if the coolant temperature sensor was faulty it might tell the ECU the engine is cold and therefore needs a higher idle. It's probably more cost effective to get your car plugged in to a Vag-Com, see if any faults have appeared, clear them and see what comes back again to make sure it is a current fault.
