This problem started after i was driving hard when the car was warm but now its doing it more or less all the time now. Its like a boost leak but its not because i have checked. Changed spark plugs a few times, new maf sensor, new ignition amp, new fuel filter, n75 bypass and its still there. Havent changed coilpacks because i have heard there reliable on the agu engines. Some one help please. Got told by a audi specialist near me it could be the flywheel??
