    As u may have caught on the odd post i have a dodgy idle when it coughs like it tries to misfire but then goes back to normal when it does this there is a clunk as obviously its kicking back to normal i tried to explain but was hard to so popped the phone under the car and let it idle for a while did a 15 min vid and selected a min where it was doing it (sometimes does it more often then others)
    The two little clunks you hear is when it coughs and tries to misfire...Is this my bottom end going etc or is this literally the misfire sound from underneath
    If i put small amount of revs ie 1.5k instead of 1 it wont do it at all

    to be fair even if its incredibly small revs so the idle is constant it doesnt make this sound

    Have you scanned the car with vagcom to see if it's logging any error codes?
