Sensor malfunction in the primary hydraulic system.
Check the position sensor in the primary hydraulic circuit, the connectors, and wiring.
What you'll see
It is no longer possible to diagnose the primary hydraulic system for power steering - as a safety precaution, the electro-hydraulic pump of the secondary hydraulic system is started whenever steering is needed. * A warning will be displayed in the ICL. * If a simultaneous sensor or hydraulic malfunction in the secondary hydraulic system is present, a (different) warning will be displayed in the ICL.

Diagnostic depth
Faulty position sensor in the primary hydraulic power steering system – it indicates a flow though there is not any.
• Defect wiring o loose connectors o open circuit • Defect connectors • Defect position sensor (power steering driven by engine).
