V6S Engine Rattle
Hi all,
I'm new to the forum, had hoped to introduce myself on better terms, but unfortunately my 2013 V6S seems to have an engine rattle. Car was in for a service today and the garage noticed it was louder than other cars they've had, but they don't have the necessary tools to troubleshoot further and suggested to try a specialist. I do have a third party warranty but wondered if anyone knows what it could be. Car drives great, no error codes etc. It's really only audible when the engine cover is off, but obviously a bit of a concern. Car has only done 40k miles. Garage thought the timing chain could be stretched or an issue with the pulley, but to me it sounds more like the supercharger. I also get a "clunking" noise when the engine turns off which I read somewhere could supercharger snout????
See what you think -
Jim

After a sleepless night and some more research, I found quite a few posts with people mentioning the coupler on the supercharger??
Sounds similar to this??? https://www.ftypeforums.co.uk/viewtopic.php?f=27&t=1504

Yep, def SC coupler / torsion isolator rattle.
The "clonk" when you shut it down is the giveaway.
Search the forums and the interwebz some more, heaps of info about this.
It's possible there are other problems as well causing other rattles - loose timing chain, SC tensioner worn, secondary fuel pump bearing(s) worn, but get the coupler replaced first and see how it sounds.

Mine is currently in for the same...JTB00356 or SSM74810 are the Jag bulletins that they're currently looking into.

In that post it mentions " he upgraded couplings are supposed to be good for more like 100.000 miles." Is that for the aftermarket one, or have Jaguar upgraded the part in later models?

I believe the replacement parts from Jag are upgraded compared to original components.

Let me know how you get on. Is yours under warranty? I have a third party warranty, but suspect it may be a fight to get them to pay out since nothing has technically failed, just "wear and tear".
