Hi, I have a 2002 320d. Ever since I got it it has been very smelly in the car when cold especially if stood running. Its a fumey smell, almost as if the cars fans/heaters etc are drawing in the fumes. Any ideas on how to fix???

Maybe a microfilter change? Charcoal based one.

Will be worth checking the pollen filter box is attached properly to the bulkhead and the drains are intact. The box is screwed to the bulkhead with T30 Torx screws
