    Changed spark plug - no change
    Swapped coil pack - no change
    No oil in plug well so can rule out arching

    Any other suggestions?

    Check the coil pack loom as these deteriate due to the heat in the area, the insulation cracks and breaks down ;)

    I had to replace mine awesome gti do a replacement loom to splice in if this is the case with yours, think it's £30 iirc

    If its an AGU engine it will more than likely be your ignition amplifier on the side of the air box. A very common failure.

    Cyl 1 is at the Drivers side of the engine.

    I guess its possible the A3 is wired differently, but on the A4 its almost always cyl 2 that drops out first when the ICM dies.

    It's cylinder 2 that died on mine as well! How much will the ignition amp cost? Thanks!

    Thanks. Have anyone tried the 2.0t coil pack conversion on an AGU? Any idea / guide on what is involved?
