Dealer installed the incorrect mircofilter
Factory filter was changed two years ago and I paid my Center to perform the task at the time. A total waste of money! This go around I performed the task myself. The mircrofilter that was installed two years ago was the filter for E90s without Auto A/C (64319142114). Why they even carry this filter is well beyond me, especially given all NA BMWs are equipped with A/C. Nevertheless, the new filter I installed this evening is the correct filter, carbon (64319142115).
