Thanks. I bought the Haynes book for my car and it stated that either the heater core (what you're calling the heater matrix?) is plugged or the heater control valve is stuck. I think this is the same as what you are calling the "heater matrix shut off solenoid" Do you have pictures? There...

Does any one know where the heater control valve is located on an 1997 A4 (2.8 quattro)? I bought the Haynes book and it doesn't show where this is located, just that it is my problem.

I'm wondering if anyone has had the heater in their A4 go out? Last winter I noticed the heat seemed cooler than it should be, but this year it blows cold air. Is this something I can fix on my own or am I going to be at the mercy of the dealer?
