    Channel numbers for dual ECU C6 S6

    Hello, would someone be able to provide me the channel number (I assume same number for both ECUs) for short and long term fuel trims. This is for a 2007 S6

    Specifically need to monitor idle and full load trims on Bank 1 and 2, which are both on pass side, 3 and 4 being on driver side.
    Have B1S1 lean and B2S1 rich codes pop up. All new lambda sensors, suspect bad injectors or air leak?

    Have you looked in advanced measuring values? the PIDs are shown in a drop down list.

    2007 should be pretty standard:

    Long-term in MVB 032, Short-term in 033.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Advanced measure values has always been greyed out for me, on every single dual ECU car (multiple S8 and S6s)

    on some older modules, that is the case. Uwe has given you the fuel trim block numbers you need.
