I've seen a number of posts regarding the inside of cars steaming up, etc. Well my car was very guilty of this even when there was no in the car other than me. Well last week I was changing the oil and the oil/air/fuel filters but also changed the pollen filter. The difference is unbelieveable it hasnt steamed up inside since. Over the years of bringing it to Audi it was probably never changed. According to Haynes its only supposed to be changed every 40K, but for the sake of a few quid I for one will be throwing one in every 10K!
