Yep your right about waterpumps. The cable on the polo is a self-adjusting type, but there is a spring that tensions on the release lever, this was not tight enough(not enough spring tension). So there was too much play on the clutch bearing. Still makes me laugh, Wheelbase ridiculed my dad for suggesting that the problem was clutch or gearbox related, they said it must be the waterpump mounts. Even though the noise disappeared when the clutch was depressed! no had to be waterpump mounts. Stay well clear of Wheelbase of Hersham, they are crooks and scumbags.
