When my climate control is set to low it closes of the outside air recirculate flap ?
when i noticed this last night it would open again if i pressed econ button , or turned temp upto 20 c ,
my climate has had a musty smell when i first start it for a while now ,
Even though its had a audi aircon service last yr and ive put a couple of treatments through it my self ,New Pollen filter
So the question is how if poss can i tell the HVAC unit to stop doing it ?
i have VCDS FulL hex Can Cable and in measuring blocks it was the hvac unit telling it to open close , so im thinking it may just need coding ?
any help much appreciated
