    Hello people,

    This-morning driving to work (VW Scirocco GT TDI 170) I had the engine management light come on, when I arrived I plugged in my VCDS cable and software and it reported the following fault:

    Address 01: Engine (CBB) Labels: 03L-906-022-CBA.clb

    VAG Error Code: 08598/18628/008598/5119/5120/5121

    EOBD II Error Code: P2196

    Fault Location:
    Oxygen (Lambda) Sensor 1 (G39), Bank 1 - Signal Stuck Rich/Signal too High (Rich)

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Excessive Fuel Consumption.

    Vacuum leaks.
    Wiring/Connector(s).
    Oxygen (Lambda) Sensor 1 (G39).
    Fuel pressure.
    Injectors.
    Air intake restricted.

    Possible Solutions:
    Check/Replace all faulty Wiring/Connector(s).
    Read Measuring Value Blocks (MVB).
    Check/Replace Oxygen (Lambda) Sensor 1 (G39), Bank 1.

    Description:
    The front Oxygen (Lambda) Sensor 1 (G39) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The Oxygen (Lambda) Sensor 1 (G39) has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The Oxygen (Lambda) Sensor 1 (G39) signal is sent to the Engine Control Module (ECM). The Engine Control Module (ECM) adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

    I cleared the code at lunch time and took the car for a 20 minute spirited drive to get temperatures up, incase of buildup of carbon.
    Anyway.... no return of the code yet but it's early days.
