Im having an issue getting my cabin filter to go back into its housing. A week ago i dropped the filter to check how dirty it was and then slipped it back in w/o issues. I just purchased a factory OEM replacement and now none of them will fit back in. I have aligned the angled part of the filter in the right orientation but it almost seems like the top of the filter is hitting something and leaving about 1/4 in that wont slide in. I have a b8.5 A4 if that helps. For right now im running it w/o a filter, but would like to figure out whats going on. Ive tried messing with the fresh air/recirc to see if the flap was getting in the way, but i dont even think now that its related. Thanks in advance!
