A charge pressure test will confirm, your local indie or dealer should be able to do this and tell you the result inside 1/2 hour
thanks thanks for the reply steve,would that be anything to do with the turbo boost censor sending to much pressure to the turbo ? thanks daren
My Turbo whistled had a bit/lot of black smoke the fix was a £3.20 O-ring from MB on the inlet side of my Turbo.
turbo hi thanks for the reply, mine is not smoking yet but the exhaust smell is not as it woz, had a look at the turbo this morning and there is no play on the impaler/empaler!!!!!!! blade
It is quite common for turbos to whistle when cold. Usually goes away when hot. I found that using heavier engine oil (15/40) made the whistling worse. Mine has been doing it for years with no issues.
