    I just ran a vag-com check on my s4 out of intrest and its come up with:
    16538 - Oxygen (Lambda) Sensor B2 S1: No Activity
    P0154 - 35-00 - -
    17536 - Fuel Trim; Bank 1 (Mult): System too Lean
    P1128 - 35-00 - -
    17536 - Fuel Trim; Bank 1 (Mult): System too Lean
    P1128 - 35-00 - -
    17528 - Oxygen (Lambda) Sensor Heating; B2 S1: Open Circuit
    P1120 - 35-00 - -
    Anyone know which bank of cylinders theese codes are reffering to?
    and better still which sensor?
    Thanks :think:

    have you tried clearing them then going for a run then scan again. Could have been an old fault

    bank 1 is drivers side, plugs numbered 1 to 3 (front to rear
    bank 2 is passenger side, plugs numbered 4 to 6 (front to rear)

    B2 Lambda is a real pig to do, you definately need an O2 sensor socket to remove it, i did mine by cutting down a 22mm spanner but if you don't have a few kicking around that you can butcher you're fecked.

    once you've changed it and cleared the fault codes i'd guess the lean faults should go, that's assuming you're using decent fuel, i used to get all sorts of fuel trim readings before i knew better and changed to v-power
