a question for all u guys who have the new 4.4tdv8
when accelerating and letting off throttle do you hear a loudish wooshing noise
sounds like turbo wastegate
dealer said its normal on the new twin turbo but i,m not convinced
can someone try theirs and see if it,s the same

If its a twin turbo there will be a lot of pressure built into the system and air volume that will get dumped through the recirculating dumpvalves so it should be louder than say a TD6 or the older 3.6 tdv8 as the turbos are bigger IIRC for the 4.4.

but then sound insulation should sap most of it up.

Is it down on power at all?
have you compared to another 4.4tdv8 as surely the dealer must have a demo car in?

not tried another at dealers yet but will this weekend
just don't sound right

Yes get the same. Like a big powerful fan sound?

exactly
can hear it with window open but not closed
its probably right what the dealer says about the 2 stage turbos but just wasnt sure

Mine has the woosh, although I wouldn't say it was excessive.............but then I can't remember how loud the older engine was as I only test drove one briefly with the window shut !

Certainly can't hear this one with the windows up.

Mine is audible with windows closed too...makes me think something is up with mine now! It's mostly when just setting off from a standstill. Right?

To be honest I usually have the radio or cd on, so even with that quiet I can't really hear mine.

Next time I'm going out I'll have a proper listen & report back my findings !

With radio on mine isn't audible either

cant hear it with windows up and radio on
just with windows down and letting off throttle
perhaps dealer is right

Had a good listen today and all I can hear is a slight, brief whistle at the start of acceleration & that's only with the window down and not constant. Kind of get just a little blip of a whistle - I guess as the air gets sucked in & blown out.
The engine does roar (or purr), but it is a diesel after all.
