A4 Se Tdi(130) Auto Stalling and Juddering

[Spuddy_spud_spud]

Hello

I have a 2004 A4 Se Tdi Auto Estate that keeps stalling when pulling off, and if it doesnt stall it can judder like crazy, almost kangerooing off the line. Hill starts are a nightmare.. If im very gentle on the flat i can pull off with no problems, but we're talking very careful... Is not as bad when cold..

Have had the gearbox oil changed but that hasn't cured it. Garage think its just the gearbox thats causing it; They didnt notice anything out the ordinary on live ecu data either.

Does any one have any ideas? It almost feels like a fueling/air problem to me.. Swirl flaps or something maybe? (If it even has them) 

Cheers in advance!
