Active Body Control (ABC) Repair – OEM Level
Active Body Control (ABC), including Magic Body Control (MBC), is one of the most advanced and complex hydraulic suspension technologies used in high-end vehicles.
The system combines high-pressure hydraulics, electronic control, and precision mechanics, making correct repair possible only with specialized equipment and real engineering know-how.
AirTec provides complete OEM-level repair of all ABC / MBC system components, with full testing, verification, and long-term reliability.
ABC / MBC Shock Absorbers – Complete Mechanical & Hydraulic Repair
AirTec performs full repair of ABC / MBC shock absorbers, including:
-
the shock absorber itself
-
the integrated ABC / MBC hydraulic system
We do not perform partial repairs.
Each unit is restored as a complete system, both mechanically and hydraulically.
Seals, Bushings & Protection
As part of the repair process, all seals, bushings, and dust covers are replaced.
These components are critical for:
-
correct suspension behavior
-
elimination of vibrations and noise
-
protection of the hydraulic system from contamination
-
long-term reliability without leaks
The ABC / MBC hydraulic section is rebuilt using OEM-equivalent sealing components, ensuring:
-
long service life
-
stable operation under high pressure
-
elimination of recurring hydraulic leaks
Testing & Verification 
-
the shock absorber is tested on an electromagnetic EMA shock absorber dyno
-
the hydraulic section is tested on a dedicated hydraulic test bench, in combination with the EMA dyno
➡️ This allows real operating conditions to be reproduced, not theoretical or incomplete tests.
All test benches and specialized equipment are described in detail in our Workshop section.
ABC / MBC Valve Blocks – No Half Measures
Repairing ABC / MBC valve blocks requires far more than standard online “repair kits”, which typically provide only temporary results.
Our approach
-
use of OEM-equivalent sealing components, not universal kits
-
full restoration of the solenoids, not just resealing
-
replacement of all critical seals, bushings, and protective elements
➡️ The result is a valve block that operates smoothly, precisely, and fault-free, exactly as designed by the manufacturer.
Every rebuilt valve block undergoes complete functional testing on a dedicated test bench.
The testing process and equipment are detailed in the Workshop section.
ABC / MBC Hydraulic Pumps – Rebuilt and Tested Under Load
AirTec operates a dedicated hydraulic pump test bench, allowing us to:
-
fully rebuild ABC / MBC hydraulic pumps
-
test them under real operating load, not just at idle
-
verify pressure stability, flow rate, and overall performance
➡️ Every rebuilt pump is tested in actual working conditions, which is essential for the reliability of the entire ABC / MBC system.
Our hydraulic pump test bench is described in the Workshop section.
ABC / MBC Hydraulic Hoses – In-House Repair & Manufacturing
Hydraulic hoses in ABC / MBC systems operate under extreme pressure and are critical for system safety and reliability.
AirTec performs:
-
in-house repair and manufacturing of hydraulic hoses
-
use of high-quality hoses and fittings
-
crimping with a world-class professional hydraulic press
➡️ This guarantees:
-
absolute sealing integrity
-
resistance to pressure and temperature
-
long and reliable service life
The hydraulic press and hose manufacturing process are detailed in the Workshop section.
