Hello folks. I noticed today on my MY20, V60 T4, km 8500 - a highly noticeable "rattle" sound upon acceleration (sounds like the Predator in that movie). It seems to be coming from the engine area and starts rather immediately on acceleration and stops when I take foot off the pedal. I wanted to reach out to better understand what the cause might be, so any input from the community is helpful and gratefully accepted.

Obviously, I am a bit distraught this would happen to a brand new and rather expensive car which has car hardly been driven in the last year and a half.

Please find attached video/audio of the mentioned sound.

Thanks in advance.

this is what warranties are for

It’s hard to tell from the video. I would say have some one rev the engine after a drive to warm it up and see if you can tell if it’s engine noise, exhaust, or driveline.

If you are stationary when you hear the noise could be engine or exhaust.

Any of the noise is only when you’re moving in and you know it’s a driveline.

It always sucks when something happens to a car especially if it’s newer Good news is that you have the warranty. Good luck and make an appointment to the dealership when possible as even if you identify the noise you will need them more likely to correct the issue.

There is a TJ for the left engine pad (mount) making a clicking noise... not sure it's the same thing. We had this TJ performed on our 2017 XC90 and the clicking hasn't returned. I should add that the clicking only occurred on acceleration.

Thanks for your reply, much obliged.
So, I did as you suggested and it is evident that the noise only occurs during acceleration- and not while rev the engine while stationary. Also perhaps worth mentioning is that while in motion, the sound happens only during acceleration, but stops while gear change is taking place. Any thoughts on this.

Will make an appointment with dealer come 2022, but would like as much input from the community here and get as much info as possible on any shared experiences.

Very much appreciate your pointer here. Will most definitely take this to the dealership.
Was your troublesome sound similar to mine in the video I have posted. Your feedback is highly valued - thank you indeed.

Great, we eliminated engine mounts, and the engine itself in the prior test.

does the noise Increase in frequency with engine RPM or speed when driving? Also when you mentioned no noise when shifting, you mean in a specific gear and there’s no noise orders no noise in the moment it shifts up or down?

So we now it’s power train related. Next to rule out the transmission get to higher speed (that’s safe) when the noise is occurring and place the car in neutral. If you don’t have noise it’s the transmission more likely. If it is the transmission you can also take a look and see if it’s related to a specific gear. Please the car in the manual shift mode and ship through the gears each gear at all rpm’s and see if you can locate the gear. Or if it’s output shaft or something.

If you do still hear it it could be the differential, output shafts, drive shaft etc. with the car being all wheel drivethe Power delivery is more complicated then in RWD car.

I listened to your video a couple times. I only hear a deep metallic rattle that sounds powertrain related (the higher the RPM, the higher rate of rattle). Not so much of a clicking as was the case with ours. Definitely have the dealer check that out.

I have the same exact sound in my 2019 S60 T5, and I haven't been able to identify the source. At first I thought the engine was knocking, but it's not that. It doesn't happen when using very light throttle, or wide open throttle. My car is going for service soon, and I'll have them look into the sound. If the dealer finds anything, I'll share.

So, I have spent the last few days looking further into the matter and upon more careful testing can now say I also hear the sound while the car is stationary. I put the car in P and rev engine and the sound occurs also under this scenario. I am embedding a video as reference. Please let me know your assessment with this updated information.

To answer your question about the noise when shifting gear; there is no noise at the moment the car shifts gear. The noise only occurs upon acceleration, but not in-between gear shifts. Furthermore, while driving I have also put the car in neutral when the sound is occurring, and at that moment the sound disappears. When driving in manual mode I go through each gear and the sound occurs again on acceleration, regardless of gear.

I cannot for certain say wether or not the noise increases in frequency as speed increases. I hope you can help with this by listening carefully to the videos I have provided.

Thank you again for all your input.

It is like something resonates. Is it from under engine bay or from beneath the car or at the rear?
Now you can probably open the hood and listen from outside and get some idea where it is from.

With the new information and able to here in a little bit better it sounds like a Cadillac converter for exhaust pre-muffler that is the mosWith the new information and able to here in a little bit better it sounds like a Cadillac converter for exhaust pre-muffler that is the lose internal to the exhaust.

that would also explain why it’s easier to hear when driving has the cars under a load.

take it to the shop and see if they agree with the online mechanic lol

@Felix2020 where you able to fix this issue? MY21 here has also a rattle but I'm stuck in the warranty discussion between dealer and Volvo Cars Netherlands.

• Dealer says replace turbo
• Volvo NL says product "feature"

My dealer could not locate the issue except that they said they found 3 loose screws in the exhaust. This did not alleviate the issue entirely, but they problem is less pronounced now. The sound I had is not nearly as pronounced as yours or of the same character. And I could definitely not hear it outside of the car. Your sound sounds rather nasty and I would not say it’s a feature as Volvo claims. Definitely follow up on this. Keep us posted please.

 

[JeeBee]

Thanks for your update! For me it can't be loose screws I think. The sound disappears (almost completely) when the car is warmed up. Dealer already replaced manifold gasket but didn't solve a thing. Car is almost 2 years old now, this sound is definitely not a feature because it wasn't there before...

Hi everyone, i have a s60 polestar 2017 and sound like yours cars @Felix2020 @JeeBee, when warm up the sound disappear and return on accelerate, the sound appeared at 53.000 km, it's so weird. Somebody know what happened?

 

[JeeBee]

Just back from a holiday in Austria and the sound has even become worse... I'm awaiting replacement of the turbo. Discussion has been solved now. Appointment 29-30th of August. Will let you guys know the outcome. Here only/just 35.000 km on the clock when this sound appeared (back in May).

 

[CrisGarcia]

Thanks for the update, my mechanic still investigating the noise, he checked time chain, gearbox, exhaust system, supercharger, throttle body, engine mounts, turbo, and discarded all. Tuesday he'll check valve system, in my case, the sound is apparently located at the top engine, but he beleive that system is ok

Hello! I started a similar? thread a month ago. I wonder if my problem has the same root as yours..

Weird engine/gearbox sound

Hello everyone, I have a V60 2021 with B4 petrol engine. I noticed a sound when driving at 35-40km/h having the automatic gearbox in 4th gear. The sound can be heard after 0:16 and loudly after 0:27. Link to mp3 file Any ideas? Thanks, Andi
