Hi,

Should I be concerned about a whirring noise that comes from the
vicinity of the turbo when I switch off? You can feel the vibration
in the gear lever and hear the noise in the cabin (doors & windows
shut).

It always does many people wouldn't noice it but occasionally it is
really loud. I normally have to do some slow manouvering parking up
this is done with the engine at idle, though the ECU does adjust the
fuelling to stop it stalling of course. I can't reliably reproduce the
loud version of the whirr and the "normal" level one doesn't appear to
be affected by switching of quickly or after the obilgatory 10s of
idling.

It is your oil rotor slowing down !!!!

Perfectly normal

I have a similar noise which became louder after changing the oil
filter. It is the centrifugal filter that some examples exhibit.

No. It's the centrifugal oil filter spinning down, perfectly normal.

The quiet version I can just about accept as normal, though feeling
the vibration is a bit off putting. The loud one, well it is LOUD and
the noise is so much like something just catching that perhaps
shouldn't.

Still if the turbo isn't going go phut because of it I'm happy but if
it is going to go phut it better do it before mid November when the
warranty runs out...

Thanks chaps.

It can be quite loud. I was on the phone to the dealer the first day I had
mine, but in the end I rather liked it. It's a bit like the car saying "OK,
I can have a rest now".

I'd have been straight on phone if it had done the LOUD version on day
one... I'd still like to know why it varies so much from "Is that a
whirr I can hear?" to "WTF is that!".

Naw, that comes from the air suspensions gentle phisssssssschnk 30s to
a minute after shutdown. But you wouldn't know about that. B-)

The air sus on the Disco didn't do this, but the Rangie did. It waited
until you were several yards way and then set about the chunka-chunka psssst
tic tic routine as the suspension computer sorted itself out. It reminded
me of a dog turning round and round in its bed before settling down for the
night.
