This bulletin applies to 2013 Volkswagen Passat sedan models. It may be noted during a Guided Functions or Vehicle Self Diagnosis scan that address word 04 for the steering angle sensor displays active. A direct communication to the steering angle sensor is not possible through this view.
A concern with the G85 steering angle sensor should be diagnosed through the fault code listed, or using MVB 7 in address 44 Steering Assistance, or MVB 4 in address 03 Brake Electronics.
The sensor should read 0 degrees (+/- 3 degrees) in the straight ahead position, and over 500 degrees at each end stop. The end stop readings should be close to each other, where one stop will be a positive reading and the opposite stop a negative reading.
