Air suspension calibration
Calibration tells the control unit which body position should be considered normal.
Symptoms
- The body sits uneven, and the suspension operates outside its normal range after a repair or sensor change.
What's included
- It is required after replacing level sensors, air springs or the compressor, after suspension repairs, and after any intervention that changes body height. Without calibration, the system uses old values: the body sits unevenly, the suspension works outside its correct range, errors appear, and the vehicle may change level by itself while driving. We perform the procedure with a scanner according to the manufacturer's method, measuring actual heights at control points rather than estimating by eye. After calibration, we check every suspension mode.
Additional checks
- Error codes in the control unit
- Operation of all suspension modes
Why it matters
Without calibration the system relies on old reference values, and the car can shift its ride height on its own while driving. It's done with a scan tool, measuring actual heights at control points rather than by eye.
More details
Calibration tells the control unit which body position to treat as normal. It needs to be done after replacing the height sensors, air springs, or compressor, after suspension repairs, and after any work that changes ride height. Without calibration the system relies on the old values: the body sits unevenly, the suspension operates in the wrong range, fault codes appear, and the car can change its ride height on its own while driving. We carry out the procedure with a scanner following the manufacturer's method, measuring the actual heights at the reference points rather than doing it "by eye." After calibration we check the operation of every suspension mode.
