Cabin Air Filter Issue

scoobdawg · 04-19-2021, 08:22 AM

Have a 2012 535 I Xdrive - Went to replace my Cabin Air Filter this weekend, when I took out the old Air filter (installed by a BMW specialty shop) there was only 1 filter - I was under the impression there should be 2 filters? When I went to install 2 filters back in, I could only fit 1 no matter what I did - Guessing the BMW tech had the same issue - These are non OEM Hengst E2978LC-2 filters - A few questions

1- Should there be 2 filters???
2 - Should they fit easily?!?!
3- Did I buy the wrong filter???

If so would the MAHLE LAK 467/s be correct or should I waste the $$$ at BMW

Any help is really appreciated..

Thanks!

There are two filters. They are parallel to each other. It should look similar to this.

Do they look like this?

Thank you both! I didn't realize there were two separate compartments - 20 minutes later and I'm all set! Looks like the filter in the back hasn't been changed in who knows how long - It was nasty - Thinking the Mechanic who changed my filters last didn't have a clue - But from now on I'll do it myself

Thanks again!

The filters are also directional. If they have a tab, the tab should face TOWARDS direction of travel (aka nose of car). If they do not, the arrow should face AWAY from direction of travel (aka trunk of car). There's a lot of bad info on the direction of the filters.
