This is good info to have. Does it imply that you need to have the car running and in recirculation mode when you replace the filter or can you shut the car off once it's in recirculation mode and then replace the filter?
The reason I ask is that some systems have 'home' positions for flaps like these on power down and then revert to last setting positions when powered up again. If you shut the car down the potential exists for the flaps to move to such a 'home' position, I.E. away from whatever recirculation position it may have been set to when running. Barry |

Anyway, unless you can figure out a way to change the Cabin Air Filter without opening either front door (the only kind of door I have on my 430i) you're going to be in 'Standby State' by virtue of having an open door so you can enable Recirculation and select a slow fan speed and the HVAC system would remain in that operating mode while the filter was changed. That works! Barry |

Yeah, this is good info. The first time I tried to change my cabin air filter I didn't do this. Luckily I didn't force it in. I just assumed the filter I had didn't fit right and I would exchange it. So I procrastinated, then came across a YT video explaining this procedure. Glad I did. Changed it out last week and it was easy. Though, why in the world would BMW do it this way, I have no idea.
