    Audi A3 8v 2015 error 19226 and 20169

    got these two codes but no eml light on.....
    are they related ?
    will the particulate trap bank 1 error 19226 trigger exhaust pressure sensor 1 error 20169 ?
    what would be the best way to determine using VCDS and values expected on a CRKB engine May 2015 ?

    Hi!
    1) Post a full autoscan, in Code tags
    2) Check measured value of exhaust pressure sensor with engine not running (just ignition on), engine idling, and @ 3000-3500 rpm

    Open the engine ECU, select the function for Measuring Blocks (or Advanced Measuring if your controller is UDS) and choose the appropriate measuerment value

    You have UDS based ECU, so You will have MVB grayed out. Use Advanced measured values instead. Use search window in this mode, type in "exhaust", for example
