    Get this every now and then, usually when nailing it in 1st and 2nd. Did it when I had a stock tune, still does it with Stage 1.
    it is hard to replicate as it happens so rarely and on all different roads and conditions. There is plenty of fuel in it when it does it.
    i guess it could be ESP but one would think it wouldn't be so rare an occurrence if that was the case?
    Same goes for ignition and fuelling as surely it would be more common if I had issues with those systems.

    Car is 2.0T FSI, DSG.

    It loses power for a full second before it kicks back in.

    Camfollower to be checked asap mate just to be safe. VCDS scan would be helpful too

    Nothing on scan last time I checked. Cam follower, fuel filter, spark plugs, coil packs, DV and the usual maintenance all done in last 4k miles.

    friend of mine had same problem but as far as I remember no one could work out what was wrong with the car. Gets even more difficult when you already maintained all fuel related parts. Sure its not the remap causing it? Who did it for you out of interest.

    As mentioned it did it before the remap too. Remap was done by APR.

    Check g410 low fuel pressure sensor
    Check fuel pressure in morning when car has been parked over night
    Meas. blocks for fuel pressure for hpfp and intank fuel pump with car at idle / car being driven
    Check voltage for intank fuel pump
