Default 2000 A6 Avant - Cold Heat?

Hey guys -

Question I'm hoping you might be able to help with. I've got a 2000 A6 Avant. The heat is blowing lukeworm. I can fiddle with the settings and get it blow hot for a sec, but then it switches over and blows lukewarm at best. Weird. Would appear that the heat is getting generated, but can't get it to blow hot out of the vents. Wondering if it's the Heater Control Valve? Anyone with experience on this - would be appreacited. If it is the heater control valve - is it difficult to replace myself? Thanks again.

T.

Use vag-com to check the hvac control system.

Could even be faulty thermometer in the climate unit, reporting the air is hotter than it is. So the automatic climate unit adjusts the temperature to colder.

Vag-com would be helpful here.

Bleed the air out of the system.
What work was done since the heat last worked?
