If it needs throttle to keep it running until warm, then it could be something as simple as a faulty coolant temperature sensor making the ECU think the engine is already warm and leaning off the fuelling. Any proper mechanic should be able to check this by looking at live data on a diagnostic machine.

I happened to meet a mechanic today who also suggested this

We've decided to pull the car from VW and sell it for scrap/take it or leave it but I may ask the garage if they have checked this.
