Btw it also confirms the compensation for aging...
"Tolerance Adaptation
The damper force is diminished as part of the operating time function. Diminishing damper forces are compensated by current (amperage) reductions which are calculated by the tolerance control. This also individually compensates for mechanical damper wear on each axle."
...as well as reset/clearing adaptations:
"Notes on Service
Mechanical wear causes the dampers to weaken over the service life, therefore a running time memory adapts the damper curves towards a harder setting (over time). Faulty dampers must be replaced together (in pairs) on a single axle. After a replacement, the running time memory for the front or rear axle must be reset with the BMW diagnostic equipment"
Interestingly it speaks only about function over time rather than mileage. I would have thought mileage/driving have a greater impact than potentially parking over long time, good to know.
