DIY - Replacing Cabin Filter 2009 E350
If anyone notices updates or corrections that are needed I can re-post it. Next I'll do the oil and filter...after that the air filters.

The filter was $31.95 from my MB dealer. Part No. A-211 830 00 18 64
Some comments:
1) Unlike the photos provided above for later models, on the 2003, there is no cover with screws over the filter housing. You have direct access to the housing. It has a decal on it saying the battery is in the trunk
2) The only fastener was the 10mm nut on the front. Access to the nut is perfectly easy
3) The "clips" mentioned did not need much persuasion with a screw-driver. It lifted out quite easily. I was surprised
4) This filter simply cleans the air as it enters the cabin. If you are recirculating air, it will not pass through this element. Therefore, don't expect replacing THIS filter will clean cigarette or other odors from the cabin
5) The hardest part, and it isn't really at all hard, is removing the filter element from the filter housing once you have removed the pair from the car. There is another clip on the housing that you need to lever apart a bit to get the old element out and to get the new element in to go in. Not that difficult.
If this job takes you more than 15 minutes, I'd be surprised.

I can't find them if they are there. See picture.
How do you get rid of the cigarette smell? It's been detailed by the dealer, but I don't know if they smoke between times. I can smell it on the MBtex seats.

I too have the same car as you and thanks for an informative procedure for the cabin air replacement procedure.
I would like to add the following. After releasing the "clip" on the right side , I tilted the box upwards towards the underside of the hood and while doing so pushed it to the left. This released the box assembly quite easily. Space sure is tight on the left side even for my small hands!

+2 on this question? Is the cabin filter ONLY on the passenger side engine compartment? I replaced that already but someone mentioned somewhere else that there was one located under the glove compartment... is this true with 2009's?
Thanks,
