Replacing BMW E60 Microfilter (cabin air filter)

The cabin micro-filter is normally replaced some time around every oil service. Once your car is out of the free maintenance period, you will have to do this yourself. This is easily done on the new BMW E60 (5 series) model. There are two filters and they are both located near the windshield under the hood.



Remove the filter covers. Each is held in place with a snap bar spring and a hex lock. Use a 13mm hex socket to unlock it with a half turn hand twist.


The passenger side cover has a hood switch that need to be disconnected first.












When replacing the filter, make sure you fit it snugly inside the housing. Here, the previous dealer service did a sloppy job fitting it so air leaks around the circled area.

Here is a good fitted filter.















Reassemble in reversed order.
