The filter you are talking about is the Micron-Filter - located behind the center console at the bottom against the firewall. Kinda of screwy to change out, but not difficult. Will cost about $10 for the filter and about 45 minutes the first time you swap it out.
Check out www.bmwe34.net - has the procedure on there.
