Just noticed a whine that seem to be related to turbo but unsure,
its really annoying at low rpm sounds like a USA type police siren
is it a sign turbo is on its way out?
cars only done 42500 mls with full service history any help

Sounds like the turbo or EGR valve but worth checking the exhaust for any leaks. What year is your car? Do you know the engine code? It can be found in your handbook or on a sticker in the boot near the spare wheel, usually something like BXE or BKD etc
I am looking into a new EGR as its the cheaper option I have noticed that on idle it runs ok with no whine, then the whine comes in after a couple of minutes on idle if i blip the throttle it goes away. hopefully the change of EGR will sort it, will post back when i get it changedQuote:

On inspection of old turbo slight amount of play on the bearings,geuss it would have run on for a few more mile before it let go
cars only done 42500 mls with full service history. Thats pretty poor milage from a turbo - do you just switch it strait off after driving it ?? instead of letting it idle for couple of mins so that turbo gets a chance too cool down With oil still lubing the bearings ???
Yes I know its not good at allQuote:

Yes always give it time to cool down etc
Just a thought --it may be worth replacing the turbo oil feed pipe-from fillter housing to turbo-- just incase it has suffered the dreaded baked oil in pipe, its not uncomon for that too happen-and it would explane the Very premature fail of turbo !!!
Yes both oil feed /outlet pipes were changed
