How to calibrate Airmatic Suspension on W211 using Xentry DAS?

Simple overview of calibrating my W211 suspension using the inclinometer app on my smartphone instead of Romess tiltmeter. I did not have a picture to calibrate the front suspension, but only the photo of the rear calibration. In the photograph showing the rear voltage value at 2.34 volts, it was confirmed that the rear axle was -1.2 degrees. The original value was close to 3 volts, the rear part of the car was 1 1/2 “lower and the rear axle was -2.8 degrees.

-Straightened steering wheel by adjusting tie-rod ends (was offset to 1:30 o’clock). Set front toe to 0.5mm toe-in each side using string measurement.

-Calibrated suspension using Xentry DAS. Rear suspension sitting too low causing too much negative camber. Right front suspension lower than left front. Corrected.

-Before: ** = “Axle Inclination” (rear) or “Control Arm Inclination” (front) Left Rear Right Rear Left Front Right Front Camber -2.3 -2.3 -1.3 -1.2 Height 25 3/8” 25 3/8” 26 ½” 25 5/8” ** -2.8 -2.8 +2.6 +2.4

-After: ** = “Axle Inclination” (rear) or “Control Arm Inclination” (front) Left Rear Right Rear Left Front Right Front Camber -1.6 -1.7 -1.1 -1.2 Height 26 3/4” 27” 26 ¼” 26 ½” ** -1.2 -1.2 +3.1 +3.1 Note: Rear inclination measured directly off of drive axles; front inclination measured off of “nubs” on lower control arms. Confirmed voltage values within range, then entered new inclination values into Xentry DAS for programming. Successfully programmed suspension control module.

A brief overview of calibrating the suspension on my W211 using an inclinometer app on my smart phone in lieu of a Romess inclinometer. I did not have a photo of calibrating the front suspension, only a photo of calibrating the rear. In the photo showing the rear voltage value at 2.34 volts, I was under the car confirming the rear axles were at a -1.2 degrees. The original value was close to 3 volts with the rear of the car 1 1/2″ lower and the rear axles were measuring at a -2.8 degrees. 2005 E55 AMG -Straightened steering wheel by adjusting tie-rod ends (was offset to 1:30 o’clock).

As you can see, Xentry DAS calibrate Airmatic Suspension on W211 successfully.
