    What does this fault code mean?

    Shift fork B shifts itself out of the N position without a request from the control module. The cause may be a hydraulic fault or a damaged position sensor.

    Possible causes

    • Fault in the hydraulic system
    • Damaged position sensor

    What you can do

    1. 1Read and clear the code, then road test the car to see whether it returns
    2. 2Have a workshop check the hydraulics and the position sensor; both fault sources are in the mechatronic unit, which is replaced in that case

    Symptoms you may notice5

    • The malfunction indicator lamp (check engine light) comes on or behaves abnormally
    • Yellow symbol and text message in the display
    • No movement forward or in reverse with a gear selected
    • Shifts occur too early, too late or too often
    • Automatic engine start and stop does not work, including at idle

    General guidance for car owners. Diagnosis on the car can point to a different cause.
