Hi, i brought this car back in 2011, at the time i was not told was a cat d and it was my first car so i did not do a hpi check as it was from a dealer, anyways having spent £1000 in a month repairing it, i had a rattling/vibrating sound coming from the drivers side, i was told this was the coil pack, having the coil pack change the noise is still there!! any ideas!
