All I know is after changing my filter my AC is like night and day. Before I would have to put it on Full Blast for only 1 person to be a lil comfortable now its I keep it on Auto it stays on 2 dials and it keeps the entire car cool. When I took my filter out it was like a birds nest was laying up in there. It was crazy.
SAme here man, mine was even dirtier than a nest, the car has 208,000 on it and i dont think it was ever changed, i changed it and the ac is like if i put it on 3 u feel cold in the car, i gotta keep it on 2 to keep the car cool enough and not to catch cold, haha.. do u think the ac systems are different in the 6cyl BMw's and the 4cyl BMw's
the micro filter should be replaced if you arent getting good air flow, doubt its your hotness problem... but you buy a new microfilter pretty much like you would an air filter and just replace it instead of cleaning it...
