Little to no heat from vents. Heater control valve?
I've flushed the heater core several times with hot water through the inlet and outlet. Used CLR and let it sit in the core for 20 minutes then flushed again both ways and used compressed air both ways. Flushed with clean water and air and each time, both ways the water flows hard and strong with a full stream of water. There is definitely no blocks in the heater core.
The temperature control flap motor (pink lever) works as it should.
Where re is the heater control valve located? Is it under the windshield cowl behind the firewall?
Any other ideas???

The manual is on a computer that is 600 miles away from me. Sorry.
Best to have your own in order to work on these vehicles. I buy them as soon as I buy a car. My son got his TT about four years ago; As soon as he bought it, he ordered the manual (on CD-Rom) From Bentley Publishers for installation on our garage computer. It paid for itself within the first month. Now it has paid for itself a hundred-fold as he replaced his clutch and then later rebuilt a replacement engine. R & R'd the engine which not a simple task on this vehicle. Then a steering rack replacement, Headlight issues, cooling system work, brake system repairs and the beat goes on....

Unless the thermostat is faulty but the car comes up to operating temperature like normal.
