Most likely you need to recharge your A/C reservoir

He said the velocity was weak so the temp is probably OK. Time for a new microfilter.

yes i agree with you mark, replacing the microfilter is first to do...if filter is restricted, it can also affect the blower final stage unit to prematurely fail intermittently

How often should the microfilter be replaced? Is it something you can do yourself?
My air velocity is quite weak in comparison to when I bought the car.
Can any mechanic replace it?

How often is a matter for discussion, can you do it yourself? Yes.
On my E36 (USA version) the filter comes out into the passenger side footwell. Remove 8 screws holding the govle box in, take a connector block out of the way, and the filter slides out from the center console area into the footwell. You guys that drive on the wrong side of the road have to find the filter on your own.

if its never been replaced you should now replace the filter.

I also have a filter that should be changed on my E36 (3128ti-'98) but I am just wondering. I have no allergies so is this filter important? I could remove the old filter and not replace it. Then I would have good flow and less maintenance. My garage service manager says some of the newer cars come with a filter housing but no filter installed at the factory. That is left up to the owner.
Maybe the filter isn't needed if it doesn't protect the A/C sytem?
Thanks,

I had the same thought. If you are not allergic to pollen, and don't regularly drive in a dusty environment, do you really need a filter at all?

Sorry, didn't see your post, makes mine sort of out of place.

The filter is just a paper filter, very similar to what is used in the intake. It will block dirt particles and what not, so you could leave one out but at under 30 bucks, I think it is better to put a new one in and breath cleaner air, although it is all up to you.
