Worst part about it is if you accidentally end up pushing the recirculating flap past it's end stop resulting in poor air flow and even a slight air resistance/whistle that can be heard during fan operation. Ask me how I know because I did it last week when I serviced my microfilter. I've done thousands of micro filters and the G01 apparently is the only one you can possibly do this with. Yesterday I had to remove the complete glove box, passenger knee airbag and the blower fan to be able to access the flap and flip it back over. This is a known issue and there is an SIB for it. According to the SIB replacement of the complete air conditioning box is necessary. I wasn't about to take my car back to my own dealer for that lol.
