Failure of the component

If one of the components on the valve block fails, the following behavior is to be expected:

• Fault memory entry in the control unit for vertical dynamics management (VDM)
• Check Control message in the instrument panel

If the oil level switch fails, the following behavior is to be expected:

• Fault entry in the VDM
• Output of a Check Control message in the instrument panel
• Failsafe function, also applies to power steering

General notes 

On checking the oil level, the influence of the oil temperature must be taken into account (volume expansion). There is a "MAX" mark on the oil dipstick. The mark indicates the maximum permitted oil level measured at room temperature (20 C). Due to thermal expansion, at oil temperatures of 50 to 70 °C the oil level is approx. 15 mm above the mark. With regard to the oil level, follow the repair instructions.

Vehicles without active roll stabilization can be recognized by the lack of oil-level switch.
