Diagnostics – The Foundation of Every Correct Repair
The solution to every problem lies in accurate diagnosis.
During the development of high-end vehicles, manufacturers aim for maximum reliability and long service life of every component and system.
It is well known that in luxury and top-class vehicles, suspension technology is engineered without compromise.
Nevertheless, even the most advanced air and adaptive suspension systems can develop faults over time.
Very often, the failure of one component is the result of a problem in another part of the system.
For example:
-
the most common cause of air spring failure is a leaking shock absorber, whose hydraulic oil damages the rubber bellows
-
air suspension compressors often fail due to a slowly leaking air spring, forcing the compressor to operate excessively
-
compressors may also be damaged by contamination, caused by faulty or clogged air filters
In all such cases, correct diagnosis is absolutely critical.
Without identifying the root cause:
-
unnecessary repairs are frequently performed
-
only the failed component is repaired, while the underlying problem remains
-
repeated failures occur shortly afterward
If the root cause is not correctly identified and eliminated, the same problem will inevitably return.
Professional Diagnostics at AirTec
At AirTec, you are supported by a highly qualified team, equipped with dealer-level diagnostic systems.
Combined with our specialized test benches and measurement equipment, we are able to:
-
precisely identify faults in air and adaptive suspension systems
-
analyze both mechanical and electronic system behavior
-
locate complex, system-related issues that standard workshops cannot diagnose
We do not guess.
We measure, test, and verify.
Electronic Calibration and Suspension Setup
All modern air and adaptive suspension systems are controlled by an electronic control unit (ECU).
This module defines:
-
vehicle ride height
-
suspension behavior
-
system response in different driving modes
Very often, even when all mechanical components are in perfect condition, electronic calibration is required.
During calibration:
-
the base ride height of the vehicle is set
-
the ECU uses these values as reference points for suspension operation
Without correct electronic calibration, the suspension cannot function properly, even if all mechanical components are intact.
