    I'm having some problems with the car at high revs - 4500 and above.

    I did a few logs and have screenshots below.
    I never lifted my foot during the logs, yet it seems the throttle angle changes.
    It sounds and feels very much like a misfire, but I have new coilpacks, and plugs, so not sure what else could cause a misfire.
    No fault codes

    You either didn't get the engine up to temp or you have a goosed Coolant Temp Sensor.

    Failing CTS is a really common problem on VAG cars, & if the output to the ECU has gone down it'll cause incorrect fueling.

    Yes you are correct I hadn't looked closely, & didn't notice you were on measuring block 118.

    Have a look in measuring block 011 for coolant temp just to make sure it's ok.
