The car currently makes a whooshing noise (like a hoover) everytime I push the revs past about 2k, a bit like if you had all your heater fans turned up to max. It only happens when the car is in gear and I think it feels like the turbo isn't kicking in. The sound is definitely coming from the front, likely in the engine somewhere, but I don't have any way of putting the car "up on bricks" so to speak to rev it while stationary.

Any ideas on the problem? Also need to know if driving the car is going to make things worse, even though I'm keeping the revs low enough to avoid hearing the noise.

this is most likly a split in the large rubber hose from the egr valve, when it loses boost pressure the turbo will not spin up fully, you may also see an increase in black smoke.

Someone else has said similar, although suggested that the hose may have come off completely as the noise is like having a hoover on. I will try and have a look later. Any idea roughly where I should be looking?

Thanks!

also check the intercooler its at the front, bottom of the radiator. unless it the older type then its on top of the engine bay

I've just had a look under the bonnet and haven't been able to find any disconnected or split pipes, but it's pretty tight in there, so I can't check every angle.

Here's a few pics of the engine, could you kind folks point me in the direction of the turbo and the intercooler on my car?

the intercooler its at the front, bottom of the radiator. the turbocharger is a VNT (variable nozzle turbocharger)its at the back of engine bottom of exhuast manifold. there is a rubber pipe on the turbo inlet that gets forgoten about its hard to see.

Haynes have a manual that will cover you car "No 4807 from 2005 to 2009 (54/09)" its only £20 from halfords..

Did I mention I know hardly anything about cars.



The turbo and intercooler both sound like something I might need to be underneath the car to see, is that right?

Appreciate all your help!

yes you get a good view for underneath, you have remove the shield from under the car frist.

It turned out to be a split pipe attached to the turbo in my case, as suggested. It's happened to me twice now on different pipes.

Unless you're handy at repairs, get it to the garage pronto and keep the revs down in the meantime.

Just had my 2nd one fixed at a dealer for £120 all in.

However, if your car doesn't have a turbo, it may be something else.

check the 90 degree rubber turbo pipe.

its located to the left, top of the engine as you look at it from the front. it may have a split on the inside bend. costs around £40 from dealer.

Brilliant replies to the whooshing noise. I've been trying to figure it out for ages. I've posted 2 shots of my car, wide and close up where you can see the split, for future sufferers and attached them as well. Luckily for me the split was on top and easy to see.
