Metallic whistling noise under full load (V60 D3 MY2019)

[Nicolicius]

Hello everyone,

I have recently noticed an issue with my Volvo V60 R-Design D3, model year 2019, and I would like to ask if anyone has experienced something similar.

I first noticed it while driving in Polestar mode (activated via Orbit). I do not believe the Polestar activation is related to the problem itself – it was most likely just a coincidence that I discovered it at that time.

Under full throttle, I can hear a slight whistling noise, but it sounds more metallic than a typical turbo whistle. There are no unusual noises under partial load at all.
The noise seems to occur mainly when the engine is warm. I have not properly tested it with a cold engine yet, as I usually drive gently until it is warmed up.

Interestingly, the noise can also be heard briefly after braking or deceleration. I tested this next to a wall to use it as a sound reflector, which made it easier to notice.

Under full load, the noise appears roughly between 3,000–3,500 rpm or possibly 3,500–4,000 rpm (I am not 100% certain about the exact range yet).

I have checked the turbo visually and it looks fine. There is no loss of power, no warning lights, and no other noticeable symptoms.

Has anyone experienced a similar metallic whistling noise under full load or after braking on the D3 engine?

Thanks in advance for any input.

A little boost or exhaust leak sonewhere I would say.

On my D5 similar whistle noise was created by the balancing shaft inside the oil pan area (sounded like turbo whistle, makes you think that turbo is going). However to my knowledge they did not add balance shaft to D3, so might not be that, but maybe worth to ask from Volvo if your car has it. Mine was quite loud when coming to stop without breaking, but using engine break. There is an updated version out now and of course it is an expensive part. I just bought a new part and changed it myself in my garage. Very difficult to get instructions (mainly the bolt tightening torque). Rest is quite simple if a person has hands and wish.
