AIRMATIC Pressures information
Hi friends, I just replaced front strus Code: 489 AIRMATIC Dual Control/semi-active air suspension
any one has the data for the front on how much psi / bar they should have from factory ?
my local mechanic has Autel
The objective is to check the values and if necessary adjust them but I do not have the references
thanks in advance

You set ride height based upon the inclination angle of the control arms or axles. The pressure is used to raise/lower the ride height until the inclination angle is within acceptable parameters and the voltage sensor values are also in an acceptable range. So, pressure will vary depending if your car is lower or higher in ride height.
Will not apply to your car but on my W211 a range of 5-6 Bar pressure will set the inclination angle within factory specs. I might write 5-6 Bar, but the pressures between the fronts and the pressures between the rears will generally be within 0.1 Bar of each other.
