Mercedes W212 | Most MB Owners Don't Change This Filter

How to change airmatic / self levelling suspension air filter for compressor. This filter is used on all Mercedes-Benz E-Class W212 2009-2016 Estate models. Sedan only have it if you have airmatic option.
This is not in any service schedule so don't worry to much about it, but I like to check the condition because if the filter would have been clogged is a indication that's something is bad and the system probably about to break.
That hose was also worn so is good sometimes to have a regular check and change out bad parts. Then you know the car going to run great : )
