the dealer should be able to identify the fault very easily - nearly all VW/AUDI AC systems allow diagnostics of pressures/sensors etc for quick analysis.
It sounds like a refridgerant level/pressure problem - i.e. low level of refridgerant, loss of compressor function, blocked expansion valve, etc etc.
My previous job was development manager for the AUDI A6, A8 and Phaeton A/C system - I dont know the Touareg AC too well, however if the dealer is no use, let me know what they say and I can try to give you some pointers.
