Volvo V70 D5 (163) engine whine #volvo

Broken turbo

I have a non turbo petrol... also a whine from something on the serpentine belt when RPMs go up... What is it? All pulleys align, and run smooth

normal noise

Mine dose exactly that when cold

That may by the turbo or the downpipe that leaks. Mine leaks ans do the exact same noise

Normal.

Mine starts to do that when i put sports filter.
Looks like some air intake tube is off

I’d say that most D5 engines have a really loud turbocharger somehow, this might be normal

VNT vanes on the hot side of the turbo are sticking , just need cleaning :)
