Vibration and whine at certain RPMs, particularly in this case when I was crawling at about 10mph in 1st or 20mph in 2nd gear - exactly what I didn't need going up the Parkway into the city!!
I know the MKV is a different set up, so will hopefully get a go in someone's - I'm not spending that money + fitting to find it annoys me... although I'm sure it wouldn't.
