Hi guys, I have this weird whistling sound coming from the front of the car when it’s under a load or when you goose the throttle … I just replaced the serpentine belts they need it and I thought they might be the problem. NOT… My next thought was maybe it’s an exhaust leak because I can smell exhaust under the hood. There is no leak from the turbo back I had a friend that works for a Monro test the system and he found nothing. I’m afraid that it’s coming from the turbo. Oh and i almost forgot the CEL came on yesterday. I haven't had the code pulled yet but i will.
Any suggestions???
As great as a new turbo sounds.... It's not at all in the budget.

There is a problem that crops up on the 2004.5 and up S40/V50 involving the crank case breather box and causes a nasty whistle/screech. Though as I recall, it is present at idle and goes away when you open the throttle.
For what you are describing, I'd check the vacuum lines.

Not familiar with these codes but after some google I find ppl are talking about the EVAP system.I had a whistling noise once it was caused by a half way clogged up catalytic converter.It even sounded good but the CAT had to go anyway.

That is probably the breather box. Volvo actually extended the warranty for that item.
Well all I can say is the video was made with the CAT on then soon as it was removed the whistling was gone too.
Clogged CAT robbed a great deal of power too.Guess we dont know what kinda sound hes getting perhaps he could post a sample or something but the codes probably in there because of the EVAP so there is something to look around there..
Well thanks Guys. I broke down and it is at the dealer now. I can't imagine that it would be the Cat because that was replaced when i go the down pipe back around March.
I just got the call from the dealer.... It's coming from the turbo. F***K!!

No they said it's coming from the turbo. It's still working but on the way out. I have an extended warranty but with the aftermarket stuff i have he has to check with his manager to see if they will cover it. Fingers crossed!!
If not I guess im in the market for a bigger turbo... Any suggestions?
