P05B0

Symptoms

• Check Engine light on
• Incorrect positioning of the blinds (do not open or close completely)
• Reduced accuracy of air flow adjustment
• Possible reduction in fuel efficiency
• The system may go into emergency mode

Causes

• Displacement or loosening of the position sensor
• Mechanical wear of blind travel limiters
• Deformation of the blind mechanism, limiting full travel
• Foreign object blocking end position
• Need for recalibration after replacing components

How to Fix

1. Read codes and check sensor data in real time when manually moving blinds
2. Inspect the position sensor mount for any play or displacement
3. Check the physical range of travel of the blinds - they should open and close completely
4. Make sure there are no foreign objects or deformations in the mechanism
5. Carry out the training/calibration procedure through a dealer scanner
6. Replace the sensor or blind assembly if there is mechanical wear
