Engine whirl for 5 minutes after cold start

Morning all,

On my 3rd FTYPE, current is a V8 p450 REIMS Edition, June 2021. 12k miles. From main dealer.
Previously had the v6 (not for very long) and p300 :|

Absolutely love the car, But….( you knew it was coming)

Had the car 8 weeks and after noticing a prominent groaning/whirling noise from the engine which was also prominent in the cabin I took the car back and a new supercharger/pulleys/belts were replaced (long back story) he said that once he took the belts off the supercharger the noise goes. Hence all the components replaced.

to recreate the issue I:
1) start the car up first thing on a morning (very cold at the mo and car is garaged)
2) put the car into D (in normal Drive Mode)
3) drive away
4) 2/3 mins later stop at junction or lights (stop start off)
5) can hear the car “whirling noise” in the cabin
6) further 5 min of driving and stopping at junctions etc engine is idling normal no noise in cabin
7) after initial journey noise doesn’t occur until car is left cold again (after a few hours/overnight)

Just to caveat this, when the master tech fitted the supercharger he then compared it to a new p450 and when both cars have the bonnet open you can hear the noise coming from both cars within the engine bay. It seems like it’s always there (so normal) just quieter once warm.

I’ve also you tubed quite a lot of engine idles from the F-type and you can hear the whiring/groan from the engine bay on all. My concern/confusion is should it be this prominent in the cabin?

Master tech said that they have checked a few cars and noise is there in the engine bay of others. They also sent me videos proving this.

They have told me to monitor.

Is it just because at the moment the weather is very cold and it’s the mechanics etc warming itself up?

Anyone else have this?

Can’t seem to upload any vids.

Anyone else have this?
 
That's interesting... I am picking up my P450 Reims tomorrow morning!
I've only test driven it, 3 times so clearly not in a position to comment on what is normal or not, but interested in any video links you can post so I check mine..

Also curious as to why its had a new SC already.
 
Will create a you tube account and post a link later.

Master tech thought that the new supercharger and all attached bits would remedy the perceived problem. When he replaced the pulleys etc noise was still there so he intimated a new supercharger was next step.

Supercharge was fitted and noise still there. So in reality it didn’t need one. If you listen to this car idle (you need to really tune into it) from 38 seconds you can hear the whirling, that I hear just more prominently from the cabin during the first 5 mins of driving.

As I type this, went for my morning coffee made the whiring noise. By the time I got to the shop (6mins 2miles) it had gone.

I could just turn up the stereo I guess.

As the car is main dealer supplied, I am probably going to ask them to borrow a similar vehicle, and see if it does it. If it does, then I can switch off from listening to it and enjoy the car

Here is the noise from the cabin. As I say it goes relatively silent after the 5 mins driving. All other starts that day (in short periods of time) are fine.

My initial reaction from a quick listen is that deeper noise from the point you mention is more exhaust related than a rotating type whirr. It might be my hearing though!
Is there any vibration change you notice, does it alter when you rev it?

Edit- I hear the whirr more clearly on the second in-cabin video, mine sounds like that from cold, not quite so loud in the cabin as yours, but v similar. Wonder if there’s some sound deadening missing or not attached properly
 
In order to tune in to it I have to wear my AirPods to get the whiring noise. It defo a consistent rotary noise as opposed to exhaust hum. As you accelerate it goes away, and then when warmer disappears (it is louder in person I promise.


Edit - ah so you can hear it 😁😁😁😁. Yeah maybe, I just find it odd. As I say the tech at jaguar had both cars next to each other, and theirs made the same noise when the bonnet was up. Mine does that too, it’s just during that initial stage it’s in the cabin.

It reassures me that you can..

Thank you!
 
Definitely hear it in the second video.
As I say it sounds v similar to mine, but is louder. It’s a sort of regular rhythmic whirr.
Road noise of a passing car sounds loud too, is window open?

Is the noise still there with the ventilation system switched off?

Windows etc are all closed, no ventilation, or heated steering wheel on.

Literally just pure idle with everything off.

Wonder if it still happens when warmer weather comes along.
 
My P300 makes a similar noise from the exhaust when I start it from 1-2 day rest and it's cold outiside (1-5°C).
In my case, the noise come directly from the exhaust tips, like a little "pops" with high pitch sound.

Earbuds in and volume flat out and I hear the sound of a V8 lump idling.....Am I missing something?

Maybe the high frequencies of my hearing?!
 
I have the same issue on my MY18 V8R.
Only had the car for 2-3 months and having previously had a V6S, and thought I was imagining the noise. The girlfriend says I'm being paranoid as she can't hear it!

I don't notice it that often as my typical drive doesn't really involve much stopping until the car is a warmed up, but I have sometimes at junctions heard/felt that whirring noise.
As you mention, it's not always heard immediately on a cold start. Mine seems to happen as the engine is warming up, but goes away once the engine is properly warm, and can be quite prominent in the cabin.
I thought it might be a noisy air-con compressor, but turning that off doesn't seem to affect it.

Just after I bought the car, I called out Jag assist due to what I thought was a slightly lumpy idle. Turns out the lumpy idle was 'normal' according the the bloke who came out, but I did mention the whirring noise.
He said he couldn't hear anything, and I haven't raised the issue with Jag as I don't know that I can reproduce it on demand to show them!

I'm kind of glad to know it's not just me hearing things, but not really sure what to do about it.
 
I can hear the tone change at the 38s point in the video but the sound clip - to my ears - isn’t very much use.
It sounds very much like mine does on a cold start-up. Are you sure you haven’t bought the P575 by mistake?

I hope you haven’t got a problem……

Hi Tel, thanks for the reply. Have attached you tube footage of my actual car from the cabin, is this the one you have listened to?

Sounds like a few on here have the same noise so maybe it is normal.

Hi, my wife says exactly the same! your scenario sounds pretty much the same as mine. The Jaguar techs have replaced key bearings and belts, checked pumps etc (Sorry am not a mechanic) and compared side by side like for like. So it could just be that is how they are.

I guess at the end of the day I have 16 months jag warranty.

Mine is due back for some new door handles as the current ones open and close a few times before finally unlocking! I’ve asked for a p450 for the night, so will see how that sounds from the cabin.

Hopefully you have a bit of reassurance in numbers.

I cannot open that video?
I listened to the embedded one in your post, that I quoted.

Hi moss, thanks for the reply. The you tube cabin clip is where I hear it most, which is recorded from the cabin of my car… it’s defo a P450 👀. The noise you hear in this clip subsides after a while. And it’s quiet. It just doesn’t sound great. I promise you it’s louder than the camera picks up.

The car has been inspected and components replaced so hopefully all is good. (Fingers and toes crossed)

Cheers

Are you able to access you tube?

My channel is:
https://youtube.com/@adriap6595

I have only posted one video, and it’s the internal cabin noise.

The silver vehicle embedded was just an example of the noise from the outside, it’s not my actual car. The one I captured from the cabin of my own car is on the you tube clip.

Cheers
