I don't *think* we have just hot air flap like most cars, I *think* it works by water valves letting water into passenger and driver heater matrix and you can see these under the windscreen wiper cowl.
It might be worth doing a VCDS scan. Has this happened more than once? Mine does this about twice a year and the next time I drive the car it's fine, yet the time before it is blowing cold with both sides set to HI.

Happens all the time has been doing it for about 3 months. On a very long trip say 2 hours or so the car heats up gradually. But it dose not heat up in the first 20 mins and in this weather im struggling to clear the windows to see where im going..
How do I check on vag com about these valve thingys then ? .. can they be changed ? Do they just regulate the flow of coolant to them ?

The auxiliary water pump is part of the same unit if that's relevant.
Does that work if you use the "rest" function, you should hear it? I've had problems with mine (noisy) and disconnected it. Still warms up OK though.

Ah, I was referring to D2, but I thought they were very similar in that area. I guess not....

Have you done VCDS scan for errors? Very possible some of the flaps are not working correctly if that's the case it will show error codes on VCDS.
