    What does this fault code mean?

    Third gear gives a ratio that is close to that of another gear, even though it is selected. The code is event-driven and does not indicate a fault in the control module where it is active. It is an information code.

    Possible causes

    • Faulty operation of the solenoid circuit for third gear
    • Damaged or worn clutch
    • Poor fluid quality
    • Mechanical faults in the transmission
    • Contact resistance or poor contact in the connectors to the linear pressure solenoids

    What you can do

    1. 1First check whether the transmission has other fault codes; if so, they are the root fault
    2. 2Clear the code and road test in third gear to see whether it returns
    3. 3If it returns, have a workshop assess the oil and the condition of the clutch

    Symptoms you may notice4

    • Harsh or jerky gear changes
    • No automatic gear change
    • Gear changes that take a long time
    • No manual gear change

    What the fault can affect3

    • Adaptation function is blocked
    • Neutral check is blocked
    • The transmission selects a safe gear and holds it for a while before a new one can be requested

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