Technical product information

Customer statement I workshop findings
Rear window blind unexpectedly stops mid cycle

Technical background
A component change in the rear side window blind mechanism has left the system with the potential to
'electrically lock up'. This function anomaly can manifest itself when a request is given to the door
control module to reverse the blind direction of travel during an opposing up or down cycle. This
request may originate from the manual switch in the door or from the key fob remote control.
On each occurrence of this failure an ignition cycle will unlock the system and reinstate blind
functionality. A permanent solutions is now available via a software download and parameter coding
change this can be performed using VAS-PC

Production change
Revised software incorporated into the door control module

Measure
Please advise customers who experience this phenomenon that a permanent solution is now available

Ensure a suitable battery charger is correctly connected to the vehicles electrical system for the
duration of this procedure
1. The procedure is only possible utilising VAS PC running on Bentley brand CD version 19.04 with
Bentley Brand CD update V2.0 patch installed (download from BICs)
2. Connect the Bentley diagnostic tool VAS 5052A or later approved equivalent, to the vehicle On
Board Diagnostic socket. As an SVM is required the Bluetooth connection is not recommended
