Hi, it sounds like a belt or a bearing ... could be any of the following ...

turbo bearing, a/c compressor bearing, water pump bearing (although its usually a grumble)

any aux belt either too tight or starting to break up .... if its more a Zinging sound that varies with engine speed I'd have a look at the timing belt.

Hope it helps :)

is your turbo boost gague working ?
could be the pipe has come off the manifold or has an ole in it ? could as stated be the bearings also check all the pipes from the turbo to the intercooler & from the intercooler to the inlet manifold for holes & leaks .does the boost still work or does it feel down on power could the waste gate be stuck open ? good luck !.
let us know what you find ok !

This is how my Espace IV sounded just before they had to replace the Turbo!

It could be one of a number of things but needs checking out sooner rather than later.
