Does anyone know if a E12 528i has a pollen filter for the aircon and if yes where does it reside?
Or any other common Ventilation problems.
This car blows fresh air but recirculate or aircon on hardly blows any air.
I can hear the aircon pump kick in and that common older car aircon hissing noise inside the car.
Car stood for 6 month's

Please and Thank you.
