BMW E53 X5 models utilize an HVAC fresh air cabin microfilter. The microfilter helps eliminate dirt and dust particles from entering the vehicle interior. It also protects HVAC system components from contamination. A dirty heater core would not provide sufficient heat and a dirty evaporator would not provide sufficient cooling. The microfilter is located in the wiper cowl area beneath a lid. BMW recommends replacing the fresh air cabin microfilter every 10,000 miles or every other oil change. In this article, I'll go over the steps involved with changing the cabin microfilter. It is quite easy and can be done in a few minutes.

The cabin microfilter is located at the center of the wiper cowl, behind a lid (green arrow).

Working at the wiper cowl, rotate each retainer (green arrows) 90° counterclockwise to disengage.

Working at the wiper cowl, rotate each retainer (green arrows) 90 degrees counterclockwise to disengage. Then pull them away from the cowl to be sure they are disengaged. If one comes out, as shown here (inset), this is OK, they can be reinstalled when reassembling.

With the lid open, remove the microfilter from the housing by sliding it out toward the engine.

Clean any debris (green arrow) from microfilter housing, this will prevent premature filter failure.

Comments and Suggestions:
Ty Comments: Thanks Nick...I found the location where the air filter I inquired upon goes. Now I am seeing bunch of dirt and leave like debre in the housing unit where the air filter is to be placed into. Will that cause any serious damage being in there? I don't want to drive it until get all of it cleaned out I don't own a wet dry vacuum to do job now. I recently bought this vehicle. I'm going through it before i register it.

  Followup from the Pelican Staff: Get it clean before you put the new filter in. You can remove the blower motor and clean that end too. - Nick at Pelican Parts

Scooter Comments: 2006 BMW X5 3.0. Front passenger carpet soaked in heavy rain, car just sitting on level driveway. Checked air cabin filter and it was wet towards the bottom. Poured water on cowl and it drained through front wheel wells. Think cabin air filter drains may be restricted in that it allows some water to drain but pools up in heavy rain. Any thoughts, suggestions? Carpet stays dry in light to moderate rain. Also, what is the correct orientation of the filter, should the flapped piece at the top of the filter open up or down? Do you sell the plug-in nut for the cowl lid, part # S1711947419? Thanks.

The filter should have an arrow, the arrow goes in the direction of air flow. - Nick at Pelican Parts
