    What does this fault code mean?

    The voltage from one of the transmission's three driver stages, which control the gearbox solenoids, is too low. The cause may be a damaged driver stage or a damaged control module. The other two driver stages can take over, but the function may then be limited.

    Possible causes

    • Damaged driver stage in the transmission control module
    • Damaged transmission control module

    What you can do

    1. 1Read the fault code, clear it and road test the car to see whether it comes back
    2. 2Check whether the central electronic control module (CEM) has fault codes, since they can show that the supply voltage to the transmission module is too low
    3. 3Check the wires and connectors between the transmission control module and the CEM for oxidation and loose contacts
    4. 4Have a workshop road test the car with gear changes and replace the mechatronic unit if the fault remains

    Symptoms you may notice5

    • The malfunction indicator (Check engine) lamp comes on or behaves abnormally
    • Yellow warning symbol and text message in the display
    • The automatic gearbox shifts harshly or jerkily
    • No automatic shifting
    • The car does not move forwards or backwards in gear

    What the fault can affect1

    • Shifting may be limited, depending on which driver stage is damaged

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