Heater matrix - no hot air!!!
Guys,

I have got no hot air...... i have been away for a week, got into the car and all appeared fine.... as i have been out in -30'c conditions, i wacked the aircon on "LO" as i was red hot!! anyway... when changing it back to 18 upto 28 its cold... the air con turns off but only a tindy bit of heat... checked the simple stuff.. ie coolent...

Going to get my laptop out and check VAGH-COM... however i think tjhe heater matrix has gone...

Do any one know how to fit one on a A4 - B6??

Cheers

You can't check the heater matrix with VAG-COM, If you are loosing coolant then it could be the matrix leaking you usually notice the smell in the car though assuming you have coolant in there as well as water.

The heater Matrix can't go, it can leak, but rarely gets blocked, more likely that the hot/cold flap motor is not working. If you are loosing coolant, then you may have a matrix leak, is there anything wet inside the car?
