    Interesting! Do you remember if there was a fault code or not?

    A4 1.8T -Idle speed fluctuating and Camshaft Position Sensor fault!

    I recently found that my a/c compressor was siezing and putting a strain on the engine causing the revs to bounce all over the place... could be worth checking. Mine has just been disconnected for now undtil I find a second hand replacement. Good luck!
