Newbie here...first post! I am also not very mechanically inclined when it comes to autos. However, thought I would post my problem and see if there is anything I could check before I incur a costly repair bill. BTW, I do have the Bentley service manual. My problem is that the air flow on the A/C is cold, but very low volume. With the current temps in the Denver area exceeding 100 degrees, driving is unbearable. Any thoughts on what the problem(s) may be? Thanks... :(

Not very fun to change the microfilter, but well worth it.

I saw that in the Bentley and thought that could be the problem! Thanks guys. Can you run it without a filter until I can get one?

Doesn't look like it!! Are they also called ACC Cabin Filters...about $25 online??

Would you run your house A/C without one?

Considering that many e34s didn't even come with a microfilter, I don't think it's a terribly bad Idea - unless of course you are sensitive to allergies, etc in the air.

You mean I could spend the time tearing out the glove box, trim panels, etc. and find out that I don't even have one?

No, you don't have to tearing it apart...just to find that your bimmy doesn't have m/c equipped.

Refer to the service bulletins, only the models after 1991 are equipped w/ m/c.

So, I guess if you do the math, Jack's 1995 525i should probably have one.

My E34 has a label just inside the glovebox that tells me in a multitude of languages (German first, of course) that my car is fitted with a microfilter.
