Hi Keith, this one wasn't making any strange noises (probably because the shaft had sheared & the exhaust turbine wasn't spinning) We've also seviced this car from new, always with genuine filters & correct oil and at the correct intervals. We've changed many T5 turbo's that have suffered the usual clouds of smoke & grinding noises which as you say, you can tell how a good one or bad one sounds. Should have investigated further before posting I know. Thanks for your advice though.
Cheers, Ian.
