BMW Microfilter Service Light Reset Instructions | Cabin Air Filter

Every time you replace the cabin (a/c) air filter or a microfilter, you need to reset the service light to eliminate the warning message on the dashboard.

This guide provides instructions on resetting a BMW microfilter reminder via the instrument cluster. You must replace the cabin air filter before you reset the BMW microfilter service interval.

Procedure

1. Insert the key in the ignition and turn it to position II until all the dash lights are on. In the case of a smart key, insert it into the ignition. Press the “Engine Start/Stop” button without pressing the brake pedal.
2. Wait for the service warning light to disappear.
3. Press and hold the trip odometer reset button on the instrument cluster.
4. Wait for one of the service lights to appear. First, you should see an orange triangle; after that, you will see an oil can or air filter symbol.

6. Press and hold either the trip odometer reset button or the “BC” button at the end of the stalk to reset the interval.
