View Full Version : Heater Problem

11-12-2010, 07:05 AM
I have a 1996 A4 Quattro, and the heater blows "barely warm". I ran the diagnostics test that I got from this forum somewhere (press in the recirc button and the fan "up" button) and got a code of .0 Which I assume means the system couldnt detect any faults. I'm going to try to "flush out" the heater, with water, using a tuturial I also found somewhere on here. Hopefully its not the heater core, because I don't want to tear open the dash.

Here is my question (it may sound dumb)
What does "bleed the system first" mean?
