Whooshing/whistle from driver side of car when accelerating
Hi
I get a whooshing/whistling noise on acceleration from the driver side of the engine. I could understand if the air filter is in that side of the car but it's on the other. It sounds like an induction noise. It can only be heard when in drive. I've tried revving the engine in park with the bonnet up but it doesn't make the sound. Does the turbo spin up when revving if it's not in drive ? The noise reminds me of the induction roar from a k and n filter. I've checked the intercooler and pipes but there is nothing obvious and it's annoying I can't get it to make the noise with the bonnet up stationery. Is it something to worry about or is it normal ? Otherwise the car seems fine, mpg is 28 mpg and pulls fine with no black smoke. Any advice would be appreciated.

The turbo will spin but it won't be under any load. Noises like this are so anoying to try and find. My wife's car has a vibration at certain reves when driving only. The turbo does whistle under load or at least mine does. If it's not really anoying you then just monitor the car for any signs of trouble such as black smoke or a drop in mpg.

I'd start by checking the turbo hose pipes and all jubilee clips first. Making sure that there is no splits leaks.

Mine makes a lovely whooshy noise due to a split intercooler. Mines gone at the bottom, easy to spot due the dirt and oil around it.
If the pipes are ok check the cooler. £250 from Volvo or a pattern part from eBay is £90. Not too bad to change either.

When driving, usually when max boost is (about 2500 upwards). It also has a lack of power lower in the rev range and occasionally smokes quite a lot when I get a "Engine service required" message on the dash (due to a lack of boost, the sensor throws a hissy fit).

Update
Took it to a local Indy Friday and they said they couldn't hear the noise and it was fine.
Today, engine service warning, limo mode, big turbine whoosh when revved. Convinced the Rac to remove the under tray (he didn't want to as it was big and heavy). The resonator to the turbo had come away. The top orange seal had a split and the big plastic pipe that goes under the sump from the intercooler to the turbo's bracket has broken as well. All this was mentioned in a thread I had read last week. So got the car flatbedded to a local garage now waiting until Monday to order bits from Volvo. The lesson is, if you hear a induction whoosh that doesn't sound like a turbo normally does , check the resonator as it could be a common problem as our cars get older.

At least you've found the cause now. Hope the repair goes ok.
