- Mercedes-Benz E-Class: How to Replace Cabin Air Filter
Step by step instructions for do-it-yourself repairs
DIY: Mercedes e550 cabin filter
[QUOTE=El Cid;5486995]You need to understand that most MB drivers DO NOT service their cars. The dealer makes more money for a job that they do as it takes more time than just 10 minutes. I bet a MB technician can do this close to 10 minutes but I bet they charge 1 hour for the job.
I do understand that most owners do not service their cars.
My point is that American and Asian manufacturers make it very easy and intend for owners to replace the cabin filter, if so inclined. that's why the instructions are in the owner's manual under owner DIY section. Simple or NO tools required. Ironically, changing air filter and oil are not in DIY sections.
BTW, dealerships make more profit off service than they do off selling new or used cars. However, I still use only dealerships for vehicles I purchase-bad experiences with independents in past.
I do a lot of DIY household projects and used to do maintenance on my cars, so I have lots of tools. Not sure what a Torx wrench set is though. Cars got too complicated now. Also, can get oil & filter changes from most American and Asian dealerships for $25-40.

There's no reason to swap out 7 quarts of synthetic every 5kmi. it's not "cheap insurance", it's just recreation. You're not getting 7 quarts of synthetic changed for $25-$40.

I do think in principal the 'job' is easy to complete, but given the location of the filter in the footwell, it's pretty hard to get at and makes the job harder just by nature of the difficult access.
Anyhow, thanks again for the DIY - very useful.

The panel can alternately be removed with a sharp tug, but in my case, this method made a couple of small cracks in the panel near this hook.
My 2012 E350 had developed a sour odor emanating from the AC upon startup. I noted this odor on the old filter, too. A thorough application of Lysol disinfectant "White Linen" into the fresh air intake just forward of the windshield while the AC was running on max and filter replacement has eliminated the noxious odor.

Can someone post a picture of where the evaporator is?
H
So posted pictures of the process..
Pull back carpet
3 screws T20
One hole with plastic hook finger in to release or just pull, mine was broke.
Pull down
2 outlets to unplug
Unplug foot light
Ac sensor twist whole thing quarter turn, counter clockwise, and will pull out
Pull out cover it's now loose
Remove metal clips 2 one each end, mine was missing one and you will lose one if not careful.
Slide white plastic and filter will pull straight down and out.
Hope it helps...
Next time it will take me like 5 minutes




I had no metal clips at either end of the filter frame and don't even understand why there would be any. The frame is quite stiff and the white plastic locking part should hold the parts together just fine. At least on mine it seemed to be in place just fine without the clips.
I spent most time to get the 3 screws back in place. The screw ends had to be worn out as the screws, all of them, did not want to sit straight on the tip of the there brand new T-20 keys I have. The opening for the screws is so big in plastic but the actual hole where the screws need to go thru is small compared to the indentation the screws with big heads go thru. Some thick grease on the tip of the T-20 key helped a lot.

Thanks for any replies

And yes, the air compressor for the Airmatic probably has one too in the back of the car...
Thank you again for taking the time for your block of instruction.
Be Well
