So out of nowhere this evening, our 2005 V50 started making this whining whistly noise at idle. It goes away with only a little throttle, but after about a half hour, it started getting more noisy. When I got home, I left the car running and opened the hood, and the noise is definitely coming from behind the engine, by the firewall. Is our turbo going bad, bad seal or something? Any help is greatly appreciated.

Thanks,
Matt

Possibly the PVC issue that is very common for our cars, it could be covered under warranty or the recall, call Volvo and give them your VIN to find out. Good luck!

Is there a thread regarding the PVC issue? If that is the problem, should my wife not drive the car? Damn, I feel like I grew up spending my teens and early 20s working on cars all the time, and now I know nothing about them.

Pull the dipstick a little and the noise should go away. I wouldn't drive too long in this condition. Get it fixed ASAP.

If you are out of warranty. Here is how to do it yourself:

Put another way: Perform a test by pulling the dipstick out a little, enough to break the pressure seal. If the noise goes away or changes, then you have a serious issue, very likely the oil trap/breather diaphragm. Get the car to service immediately.

Volvo has recently extended the warranty on this part to ten years for many potentially affected cars. Your dealer can look yours up, and quite possibly repair it at no cost.

+1 for the "pull the dipstick" method of diagnosis.

It is a fractured elbow in the EGR line. I had this fixed a week ago in my V50 T5 at the dealer (still under warranty). He said it's pretty common and diagnosed the problem before I even shut off my engine as I was pulling into the garage. I wish I could tell you how much the fix was, but my billl came to $0, and it was fixed same-day.

Re: (KyleBrightman)

That's another possibility, and indeed also common. That one is easy to fix. The extended warranty issue, and the issue that affected many folks here, is the failure of a diaphragm within the oil separator itself.

Either way, get it fixed pronto. Blown seals are very expensive.
