    DPF trouble code P242F Audi A5 3.0TDI sporadic

    A5 2008 8T30H9 engine code CAPA transmission KMU

    This has a intermittent fault along with other faults which I have repaired with DPF pressure sensor and updated engine software.
    The remaining issue is dpf light comes on only for a few seconds then goes back off and causes reduced power, until he stops and cycles the ignition and all is ok until the next glitch.
    Looking at ash/soot levels there are no issues, but in freeze frame data there is some text saying "Exh t Adapt TP Flt us -270 degrees C
    I presume it could be one of the exhaust temperature sensors showing a fault intermittently, if so any ideas which one from the info we have?
    If it is a sporadic fault on one of the sensors, I would expect to see a fault code relating to one of the sensors, but there are none.
    See the scan attached..
