    Sorry I don't get it - the starter is in the othe side but I thought the ring gear is in the same relative position on both flywheels?

    Nope, friction plate is different too, and the ring gear sits further away from the engine.

    Doesn't fit no matter how large your hammer is ! The s3/transverse flywheel has a different trigger for the crank sensor compared with the longitudinal engine...

    no 1.8T has its crank trigger on the flywheel, they're internal.

    Still doesnt make a difference though, it wont fit!
