Hi guys,

I was searching a lot but I could not find the exact values.
I need to calibrate the airmatic suspension on my W212 350d Bluetec 4Matic Airmatic. I tried to find the OEM values for ride height measured from center of wheel hub to fender but I could not find.
Can someone tell me what are the exact values?
380-385-390 mm? Should all 4 sides be the same height?
I have set them all to 390mm but car looks a bit high.

Thank you.

Hi there is no such value available
if you need to calibrate the airmatic you must use diagnosis equipment that is able to do so .
Then you need to measure the angle of the lower control arm as specified in wis . the tool suggested by mercedes is the romess . (there are cheaper and better alternatives just ask)
The angle you measure need to be entered in the calibration sequence to get it right , then the ride Hight will correct itself automatically after the calibration process .

Thanks for your reply. I have Xentry but I don’t have the Romess inclinometer.

So, when calibrating, I should set all the wheels height to 0 mm (zero) and then measure and enter the measured angles in Xentry?

I have ordered one from Aliexpress, here is the link: LINK

Do you have another recommended tool for measuring the angles of inclination?

Where are you supposed to measure the suspension angles at? I have the tool, but I don't see where it's supposed to be placed.

For the front wheels, you place the inclinometer on the front lower control arms, for the back wheels, you place the inclinometer on the real axle shafts.

when you start the calibration procedure on xentry it sets the base hight automatically or on older models let you set it up manually showing a green bar indication. After that it let's you input the angle values .
in my workshop i use a more proffesional tool than the one you orderd , also you will not be able to correctly position it . This is the one I'm using it's called ASAT Link it is super popular this days .
the measuring points are described in wis .

When calibrating my car specifically, does the height sets automatically or should I manually set it higher or lower using the buttons?
