    I have the same problem with my 2002 Audi A4. By "Heater Core" do you mean the "Heat Exchanger" located in the firewall of the vehicle?

    I have a similar problem in my 2002 A4 (1.8T). Heat would come out
    initially but would gradually go cold within like 30 seconds. I've had
    the following replaced:

    A/C Servo

    Water Temperature Sender

    Water Temperature Sensor O-Ring

    Coolant flushed

    I still have no heat! I just bought a replacement Climate Control head

The heater cores in these cars get clogged up very commonly. pull the heater hoses off of the heater core in the engine compartment, and use a regular garden hose to backflush the heatercore. spray in one way, then the other, untill clear water is coming out. then refill your coolant reservoir and see if that helps.

I get no heat from my audi A6 1997 car my blower works ,I changed thermostat and radiator still not working.

I had no heat after replacing the water pump on my 96 Audi A6 quattro. After reading the last post, I found a bleeder on one of the hoses going to the heater core. I just turned it and it allowed the air to escape. Then I had heat.

A6 2.4 heater problem

mcdevito75 here, Your speaking about the Heater control valve, this allows hot water (antifreeze) into the heater core so as too give you heat, (hot air thru the dash vents). This valve could be sticking, you can try to tap on it with a wrench see if it helps. Before you just change it check all associasted vacumn lines to and from this valve, also check all vacumn lines to the firewall and at the intake manifold for bends, breaks etc.

Audi a6 heaters not given out hot air

this is more than likely a problem with your thermostat in the cooling system .heres a few things to check to be sure make certain your blower fan is on high and temp setting is in the hottest setting check to see if   air is coming from your heater ducts  also be sure to thoroughly let the engine warm up 10 to 20 minutes  before checking. if the air is blowing but  luke warm still your thermostat is stuck in the open position  and will cause the engine to run to cold and performance will also suffer as will your heat will not be sufficient  to heat the passenger compartment  this repair should cost no more than $150 max to replace buy a repair shop    this is a  common problem in older cars and this is generally   a quick  repair to be made  for almost any repair facility  should take under 45 minutes to complete once repair is started

Air only gets cool and the heat only gets warm

Found this on another website from someone else with the same problem. Hope this helps.

"This is the second year for lukewarm air coming from heater. Last year I changed t-stat and add new coolant ,also new radiator cap. It helped a little but not enough. Took it to a mech. and had it flushed ,that seemed to help alot but not as hot as it used to be."

My heat won't work! Air blows out, new thermostat

The hot water from your engine cooling system is not getting into the heater core. Check out the valve that admits water into it.
