ok, have you ever had the co checked out?  one thing thats free to try is to unplug the 5th inj, possibly its sticking open and overfuelling

ideally you want to get a proper k-jet fuel pressure gauge on it, then you can see exactly what is going on in the metering head.  The WUR is responsible for setting the fuel pressure and hence the mixture while its warming up, but without a pressure gauge you cant really see what it is up to.  Has the car suffered from rust in the fuel system due to a rusty filler neck in the past?

dpends on how good the tuner is, a VAG specialist should presumably have the kit.  The gauges can be bought reasonably cheap, theres a group buy over on cgti:
