Hello. I bought a 2016 F-Type V6 S AWD a week ago. I checked the car before purchase and never heard any noises coming from the engine bay. I drove it ~250 km from the seller place to my home and the next day when I started the engine I noticed this noise from the front of the engine. It can be heard on idle and while accelerating in certain RPMs and it goes away when I let go to come back on idle when RPM stabilizes. It seems like it's coming from the front left side (looking at the car from the front). I suspect it's something related to SC pulley/bearing or any other accessory pulley/bearing but I'm not sure. I've got an appointment for next week on an official JLR but the uncertainty is killing me. I really hope it's nothing critical. The car performance is perfect, no performance issues, no misfires or anything odd, however I'm not driving it at the moment as recommended by JLR.

I leave a video attached, what do you think?

Thank you!

 

I don't hear any abnormal noises. Honestly, it has less injector, valvetrain, and supercharger noise than my 2016 3.0L.

If you could record a video (and the noise) closer to where you're hearing it, that would help us to offer suggestions.

 

Hi!

I removed the plastic engine cover and was able to pinpoint the noise with more accuracy right now. I think it comes exactly where the supercharger snout connects to the supercharger and now my main suspect is the famous supercharger coupler. I'll leave a couple videos attached here for reference. Also, on startup and turn off I could hear that characteristic rattle coming from the same place as shown in some example videos of the SC coupler issue. I read it could also be the SC snout bearing, but I'm not sure how to differentiate both. It's for sure coming from that area where the snout meets the supercharger.

Other relevant data about this vehicle: it's relatively low mileage (~35.000 miles), has a perfect official service history, didn't miss a single service. Oil looks great, same thing for the coolant.

In case the supercharger has to be removed for fixing this issue I may also ask JLR to change the coolant pipes to the new ones as a preventive measure, I don't think they will agree to put the aftermarket ones but the JLR revisited ones should work well right?

Thanks!

 

I’ve seen mentioned a few times on the forum by a few folks that JLR actually now has Jag branded metal replacement coolant pipe parts that you could use.

 

Here's a run down video on what's needed
same engine watch from beginning to end I've done many F-types Xjs XFs on this forum,

 

It certainly sounds like it could be a supercharger coupler. One way to further narrow down the possibilities would be to remove the supercharger belt and briefly run the engine. If the noise isn't present with the engine running and the supercharger not spinning, that's another indicator the supercharger is your issue. With the belt removed from the supercharger, you can also rotate the upper pulley back and forth to see if you can feel any play from the coupler.

If the coupler is your issue, the supercharger will have to be removed in order to replace it. If the supercharger is off, you might as well replace the coolant pipes and anything else that requires servicing. As DMiester (and others) have mentioned, JLR now has aluminum coolant pipes.

When I purchased my '16 F-Type last year, it had 29,500 miles. After I took delivery of the car, I discovered the OEM plastic thermostat housing was leaking coolant. Given the problematic nature of the original cooling pipes, I took the leaking thermostat housing as a sign that it was time to change the cooling pipes as well. While the supercharger was removed and I "was in there", I also changed the water pump, water pump to oil cooer tube and seals, rear coolant crossover pipe, spark plugs, a few rusted valve cover bolts, the supercharger coupler, and the supercharger oil. I also removed the symposer and the moisture retaining sound deadening material from the underside of the intake/intercooler housings. Now none of that was critical, and all but the valve cover bolts (and lower cooling pipe) could have been replaced later, with the supercharger in place. However, the parts weren't that much, and it was much easier to do it with the supercharger removed.

 

Thank you all for your answers. The car will be sent to the dealer tomorrow and hopefully fixed on Thursday. I'll let you guys know once I have the official diagnostic results.

 

Did you notice any difference in supercharger noise with the sound deadening removed?

 

You have received good suggestions regarding servicing/replacement of cooling system parts. But with regard to the supercharger damper/coupler causing noise, it might be helpful to realize that it is noise and not much else. It is not in the same worry box as engine noises that indicate major malfunctions. That said, eventually the shaft on which the damper sits will start to show wear…but it is still noise.
You should also be aware that these are direct fuel injection engines: the injectors make noise and the two high pressure fuel pumps on the engine make noise, all “normal”. Quite different from the near silent Jaguar V8 engines of the past, but powerful and fun? Oh yes…..

 

I just got a phone call from the JLR dealer, they confirmed the noise comes from the supercharger. Now they're asking for permission to remove the supercharger to further investigate the issue. They can only replace the entire supercharger (~3300 EUR + VAT) or the snout assembly (~750 EUR + VAT). I think it's just going to be the latter.

So the car can still be driven safely?

 

Yes…a rattling damper does not mean that the car is unsafe to drive. A nuisance, yes, but not a cause of any urgency. Replacement of the damper should be on the “to do” list but nowhere near the top. Coolant loss? That WOULD BE an issue of urgency.

 

I'll do both, the supercharger snout coupler (sadly have to put a new entire snout assembly) and the coolant pipes preventively. The car is already at the dealer so... I can get both things sorted out and forget about it.

Thanks everybody for the answers!

 

exactly what i did.

 

Me too, 5 years ago. I did enough stuff that the dealer didn’t charge me labor on the cooling pipes, since they already had the S/C off for the new snout.

 

Do you have the reference number for the aluminum coolant pipes? The dealer is telling me they have only 1 reference for each piece and that they cannot assure that the piece they are going to receive is not the same as the old plastic one

 

 

The supercharger whine seems more pronounced when compared to other F-Types I’ve driven. However, it’s hard to say definitively if that’s due to removing the sound deadening or the combination of other modifications that were done to the car. When I removed the sound deadening, I also removed the symposer and replaced the OEM supercharger coupler with a solid aftermarket unit. My F-Type also has a VAP crank pulley and tune.

 

Thanks! Sadly since these are considered Land Rover parts and are not in the list of parts for the F-Type the official dealer is not willing to install those. They will install the revisited plastic ones without the stitched sides. I'll leave it like this for now and buy the aluminum parts by myself, if at any time I have any issues with the coolant pipes I will replace those myself with the aluminum ones.

Cheers!

 

I'm pretty sure the appropriate Jaguar part #s have been supplied on here...

but anywho, those 2 are what's in my Ftype..and i beat on it daily and had it in the 4-6k rev band for most of a weekend a few weeks ago. She's running like a top.
