This strange sound you hear when changing gear, is it like a "PSHHH" or "TSHHH"? If so it will be the turbo dumping boost when you let off the throttle, it does this so the turbo doesn't stall when the butterfly closes in the throttle body. There might be a leak somewhere, usually the excess boost is dumped into the airbox, have a look around there or any pipes leading to and from it.

I hate to say it, but if your turbo's sucking oil from the sump then it sounds like it's a dead un. The car's at the garage now right?

Hi Jeff, i meant your turbo. If it has sucked all that oil from the sump then it's quite safe to say it's gone. Saying that though, I've heard that when the turbo takes the oil like that it causes the engine to rev really high and you can't turn it off. Did this happen to you or your mechanic?
