    even though the dpf has been removed the pressure sensors are still retained in the delete pipe , it could be one of these failed , these normally give a fault code though .
    phone up or take it back to the remappers is probsbly your best bet :cool:

    As said above, if the pressure sensor is caked then you will need to change that for the light to go off your DIS.

    upside is your not in limp mode..

    Yet! I had the DPF light and emissions light on despite the DPF delete, turned out to be a dodgy wire on the pressure sensor.

    From memory yes, there's not much else other than the software that can bring on the light now the dpf is gone.

    if you bought the sensor from Audi take it back to them and if its faulty they will change it for free.

    it is the one at the top of the engine bay.
