4.4 Levelling the measuring station
WARNING: This page is about a different car, the 2007 BMW 530xi, 2007 BMW 525xi, 2006 BMW 530xi, and 2006 BMW 525xi. However, it is still accessible from the selected car via links, so may be relevant.
The manufacturers of the BMW KDS (Beissbarth/Bosch) are able to measure the measuring area to the required accuracy using levelling devices. Any "normal" water level is not suitable for this. Lifting platforms must be levelled under load so that the uneven deflection in the travel rails is taken into account.
IMPORTANT:
Adjustment work for the lifting platform concerned must be executed by a specialist (manufacturer's after-sales service).
