Question about 2005 Volvo V50

Whistling noise in the engine

I have a Volvo V50 T5 and out of the blue a whislting noise started to come from the engine, sounded like a air was trapped inside and trying to come out. Sure enough when I pulled on the dipstick it relieved the pressure and the noise stopped. No noise when the car is cold but it comes back when temperature rises to normal levels. A mechanic tells me that it as filter box(?) by the crank case. Have you heard of such a problem and do you have a rough idea of how much it would cost to get it fixed?
Thank you.

    I have the same problem on a 2005 V50 T5 AWD with approx 21k miles on it; it sounds as if the turbo mechanism is whistling. I notice it at lower speeds, but probably only because it's easier to hear it at the lower speed. Whether or not the engine is warm doesn't seem to be an issue; it just whistles.

When to replace volvo v50 wagon timing belt?

I believe it's every 80k. Just do it if you don't know when it was done last , these are non-tolerence motors and you will do damage to the valves if you break the belt in motion.

Volvo v50 t5 oil leak

Most likely it is the breather tube and/or the oil trap box (integrated into the oil filter housing). if the box is plugged or the diaphragm is torn the box will send oil to the top of the engine via the hose.

do you also have a high pitched whistling noise?

Volvo has extended the warranty for the oil trap box (filter housing) to 120k miles and/or 10 years.

We find ourselves on the Alaskan Hwy, at Ft. Nelson. Yesterday we noticed a whistling noise coming from what appears to be brake compartment and when you apply the brake or turn the steering wheel, it...

A whislting noise would make me suspect a cracked or broken vaccuum line. Whistling as it sucks air into the system. I would check the biggest one first, on your brake booster. It is a large line coming from the engine to the brake booster assembly located behing the brake master cylinder. I would check all the lines with engine running, have a helper rev the engine slightly while you listen in the engine compartment to see if you can locate it. Also work the brakes simultaneously. Cold weather can make older lines crack which can cause a serious problem depending on which line cracks or breaks. Check all your air lines first and see if you find it in that system before assuming something more major. A crack in other engine system lines will usually produce a fluid leak of some type.....Good luck!..Mike

Hi, I purchased a 06 volvo v50 t5 and had the car checked out and everything was OK and now about a week later the engine light came on, so took it back and the mech said its the fuel sensor. The car acts...

You should have checkup with the turbo air and fuel supply system . Its not the problem of the sensor . Its is the problem concerning fuel injection system . In india such a repair or replacement of the FI system of ur car would cost almost 20000 INR divided by 50 would give you the approx amount in us$. So the fuel injection systems JET inlet pin should be faulty .
