Using Star Diagnosis to adjust suspension height
The following procedure has worked for me on several R230s spanning model years '03 and '04. Likely it is not possible to adjust the level on an '07 or newer car without access to Mercedes-Benz, and that restriction may apply to '05 and '06 model years as well.
From the Star Diagnosis main menu choose:.
Now you will be asked to enter control arm angles you supposedly measured with a "Romess" gauge. Here enter "-8.0" for the left and right front and "-2.0" for the left and right rear. Press "F2", then press "F3" on the confirmation screen which follows. You should be finished, though it may be necessary to perform a "load adjustment", and this is simple procedure is found under the same sub-menu as the level calibration.
From the Star Diagnosis main menu choose:.
Control units > Chassis > ABC > Control unit adaptations > Level calibration > Raise and lower the suspension struts at low speed.
Read the instructions on the next screen and then proceed by pressing "F2". Now you use your PC function keys to raise/lower the suspension at each wheel to your liking with this constraint: the four level sensor voltages must all read 2-3 volts DC. When finished press "F2". Now you will be asked to enter control arm angles you supposedly measured with a "Romess" gauge. Here enter "-8.0" for the left and right front and "-2.0" for the left and right rear. Press "F2", then press "F3" on the confirmation screen which follows.

This is great!!
Can this be done with a Star clone (non original version) or it requires a dealer/shop with full featured, fully licensed Star instance to made these changes?
Thanks!

Will it retain modified height after Ignition/Engine shut off?

You appear to have the developer version, since at the bottom of the main ABC menu is an item titled "Development data / Diagnosis to plant specifications". If you go into that you should find additional menu items which are all listed in German.
In early '17 I hooked Star Diagnosis up to a friend's '09 SL550. I thought we adjusted the height on his car, but I must be mistaken. I'm going to edit the 1st post in this thread to reflect that likely the level can not be changed on an '07 or newer car.

I am very eager to try this "mod" (I hate the SUV wheel gaps on my SL) but i want to make sure that i have all the necessary steps and new settings/values down before i start and then get stuck with a half-messed up ABC suspension.
Thank you!

To perform a load adjustment you park the vehicle on level ground and click a button on the Star Diagnosis PC. The adjustment completes transparently and instantaneously.
