I can't find ANY information online or YouTube etc about where the cabin air filter is on the w223. I have a 2022 S500 and although it might not be time, there's an odd smell that I'm hoping a new filter will help. Any information on where it is and how to get it out would be appreciated!

 

There are two, one is where the battery is in the front, the other is under the glovebox passenger side. This is just like other mb models. The first one filters air from outside then the second filters the air that was filtered by the first filter before delivering to you.

 

The cabin air filter on your W223 is not in the glovebox. It's hidden behind the lower dashboard panel on the passenger side.
To get to it, you must remove that entire lower trim panel. This is a complex job with many hidden clips. It's very easy to break the panel if you don't know what you're doing.

Because of this, most people take it to the dealer for this specific filter change. It's not a straightforward DIY job.

 

Yes like other models, did not say it is in the glovebox, I said under the glovebox sorry for the confusion.

It is really not that difficult although it does hurt your back.

 

Cool, I appreciate all the information! I think I can handle the job. I recently installed the S63e front clip because I wanted it blacked out and the blank rectangle distronic cover would have looked hideous. I'm actually surprised how they went about designing the front grille on the 500/580.

 

Enjoy your ride

 

I am 73 years old and have been working on my cars for the last 55 years. For once, I think that I have been beaten.

I am on day 3 of replacing the dust filter (in the engine compartment) and the cabin air filters under the passenger side dash of my 2022 S580. The dust filter is relatively easy once you spot the 2 release clips on each side of the dust filter holder. The cabin air filters require the removal of 2 screws (2 and not 3j for removal of the under dash panel. Please note that the panel has an attached air duct on its top side that runs from the console side. I disconnected it from the panel while removing the panel. I am not sure if the panel can be removed without doing so but maybe. The case that holds the 2 filters has a “door” with 1 locking tab (not 2 like in prior versions) to release the filters. The filters can then be removed and new ones inserted.

This is where I am after day 3. I can’t get the filters fully in the case so that I can close the door. Whoever designed this system should be shot. I finally gave up for the day and replaced the filters in my Porsche 911 Turbo (3 minute job) and the wife’s Volvo XC90 (5 minutes).

By the way, I purchased these 3 filters at the dealer (stupid) for $295 but refused the pay $400 for their installation. Maybe try again tomorrow or leave the car in a bad neighborhood with the keys in it.
