Microfilter?

[Huge]

Help?

Is there a microfilter in the E30 heater/fresh air system?
My 1990 318is has an odd smell (!) which I can't get rid of so I wondered if there's a manky old microfilter buried deep inside the dash somewhere.

If there is one, how do you get it out?

Any other ideas?


Thanks,

there are no filters in the heater blower system.

what does it smell off ?

Just a bit of a stale smell really that seems to be coming through the ventilation system..?

Apart from a microfilter, I couldn't think of anything else in the air system that could give off a smell?

check your carpets for moisture. Also check the vents next to the windscreen wipers. It is also possible that there are leaves trapped against the heater matrix.
