BMW E31 CHANGING THE TWIN MICROFILTERS

This one is pretty simple, no tools needed except those in the tool tray. Open the bonnet, using the 10mm box-spanner and screwdriver shaft remove the three self-tapping bolts on the cover just in front of the windscreen:

Slightly lift the moulded gasket from around the cover and lift the cover away. You will find two microfilters, a bunch of leaves and a few bumblebees. Give it a good hoovering before removing the filters (I should practice what I preach really):

The microfilters are held in with spring-catches. They both need to be pulled away from the microfilter at the same time so that the filter moves forward:

The filter can then be lifted upwards and out....replacement is the reverse process. All done, time for a cup of tea......
