My A3 also smells not good when turning airvon on and then off. And in the wet weather it smell more than dry one.
I have this one cleaner: Amazon product
It has to be used directly by spraying on the evaporator. But how to get to it? Through the cabin filter? Center vent. holes?
Morning folks
When I put my car on low and put the fans on first few mins I get a musty smell like a damp smell...any idea what it could be?
