A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Listed login code must be entered under Access/authorization before coding is attempted. After completing coding, G85 steering angle sensor basic settings must be performed before cycling key. To perform G85 basic settings manually in Vehicle self-diagnosis (VAS PC) or Control Module OBD (ODIS), start by entering access/authorization code 40168. After code is accepted, turn steering wheel 1 turn left and back to center, one turn right, and then center steering wheel. Select basic settings and enter group 1. Once display changes to ?Sensor OK? or ?Calibration OK?, basic settings have been completed. Cycle key OFF and then back ON. Clear faults to verify repair.
TT4508022023-07-10. Service bulletin. Fault code 02543 000 ?Brake Vacuum Sensor no Display? may be encountered in the ABS module.

All Passat Wagons (including 4motion) and 3.6L equipped sedans with front drive should have this function turned on (value = 1). Change the adaptation value and verify the fault has cleared. Additionally, it may be necessary to lock the vehicle and allow the modules to go to sleep to clear the fault.
