2.0t quattro 2006 8ec lost heat in cabin
when it started:
i changed the timing belt and water pump. Got them from Audi so hoping it’s the right parts. Certainly looked good.
after that no heat at idle in the cabin. Ok if revved. All bled using the hole on pipe at heater matrix and pipe across engine.
since then I have changed the thermostat, reverse cleaned the matrix. No restriction there / I could breath through it.
just seems to have very slow flow at idle.
Any clues for this car?
