It's only an earth strap, not holding anything structural on, just do it til it's just starts to tighten, give it a little nip from there and just generally don't go mental on it!

Perfect description mistral_blue and besides which there is quite a bit of thread in the turret connection and you'd have to be severely over zealous to damage anything. If a typical torque value is required then aim for 8 to 10 nm.

Update. I fitted the £4.99 Halfords earth strap this morning.

Now, I'm not normally prone to over excitement, but OH MY GOD. It's amazing. No more crazy constant background ticking. Car sounds turbine smooth. I can even hear the feint whining of the supercharger for the first time (must have been obscured by the row). It is now simply magnificent. The automotive equivalent of taking a stone out of my shoe

I've spent two months since buying the car disappointed. Driving around in Eco mode so as not to exceed 2,000 revs when the noise was bad. On the overrun it was even worse. I could even hear it feintly at tickover.

Thank you so much to everyone on here who pointed me in the right direction expecially BRC and Steve (Jagexman). And Mistral_blue for starting this thread. And to whoever came up with the fix of course.

When I took the car back to my supplying dealer a week after purchase, with a copy of the TSB, the Technician, who agreed he could hear a 'noise', still insisted that it was 'completely normal' when clearly it wasn't. They will be hearing from me shortly.....

EDIT my car is well outside the VIN range on the TSB so it clearly affects some later cars too.

Too right, be interesting to see what the technician involved has to say. I suppose you can even take him for a spin, revert it back to original , and get his response on the difference.
When it's a well known documented issue, there's no excuse for you having to sort things out yourself, especially with Jaguar being a prestigious brand.

Pongo, I've been waiting for your comment and I'm so pleased you have achieved what we all hoped you would - well done!
Like you I think the difference is night and day and having been out on a reasonably long drive yesterday afternoon, it's an amazing improvement which even my wife noticed.
Only thing to do now is not let lesser noises become more apparent

After a couple of trips to the dealer with the TSB in my hand, taking the master technician out for a spin to hear the noise the dealer could not hear or replicate, they finally agreed to replace the ground wire with the new braided wire and the sewing machine rattle is gone. Happy to hear the purr of this kitten without the annoying rattle!

Okay, here is something properly weird.

Car went back to dealer earlier this week for creak / clunk issue and replacement earth strap. And a couple of other thing.

Anyway, creak / clunk fixed. Was the rear seat fixing failure that I think I've seen mentioned before on here. All good.

As mentioned earlier in this thread, I had the dreaded sewing machine noise which i fixed completely with the Halfords earth strap fix. Joy. The dealer agreed to replace the strap. More joy.

Got car back today. I can see brand new earth strap. But the bloody noise is back. So I need to re-apply the Halfords fix (which I assume will work in a kind of Groundhog Day way). How odd. The latest strap still doesn't eliminate the noise.

Hi Pongo
can you post of strap you have fitted and I will compare with one I had replaced, which cured issue.

Hi Pongo
can you post of strap you have fitted and I will compare with one I had replaced, which cured issue.

Will do. Will have to be Saturday though as is now dark when I drive to work and dark when i come home !

The new strap is a black rubber covered one but the old one was too. My car is a March 2016. So both old and new straps are different to the original 2015 style straps of which I saw a pic on here. New one has a label so will try to get a pic of that.

Thanks

 

[Pongo]

Below is a pic of the new earth strap. It seems to have plenty of slack where the last one seemed a little more taught.

I now need to re-apply the Halfords earth strap extension to see if that re-cures it. The noise isn't quite as bad as originally. Maybe 70% as bad. Which is interesting.

I have now had the car with, without and now with the noise again. I'm really hoping the Halfords re-fix works otherwise i was better off with the old cable and fix combi

 

[Repairman]

Thanks Pongo, whilst yours looks the same as mine attached, mine is fixed to inner wing with a plastic clip just below label, is this the reason yous seems to have more slack, mine is pretty rigid

 

[Pongo]

I don't seem to have a clip. But then I didn't before either.

Am going to try the old solution again but not until next weekend now.

Waiting to see if BRCs new strap fixes his (I think his is with the dealer now)....

Hello Pongo
Car went in on Thursday/Friday. New Jag strap was fitted along with a new high level brake light. Called back in on Friday afternoon and handed over the E- pace loaner. Started up my car and oh dear the moment I heard it I knew straightaway the noise had returned! Major disappointment as I am sure it was for you. Saturday morning bright and early the Halfords strap went back on (connected to new Jag strap) and hey presto noise gone. Calling it a day now and will cheerfully accept the Halfords strap will remain in situ indefinitely.
Interestingly my new cable looks exactly like Repairnam's and I too have a clip about 10 inches down from the turret connection. Really at a loss to understand why this fix didn't fix but grateful I can return to peaceful bliss very readily and I hope you too achieve the same result. I would also add my new Jag strap is clearly far floppier than the original so all the more baffling why it didn't work as anticipated.
Good news however because the hlb was replaced foc without any discussion and a slight re-alignment appears to have been made to the rear bumper/wing even though I was told it was within permissible Jag tolerance. Final icing on the cake the car passed its first MOT with no advisories. Still have a week or so of warranty but I think I'm happy as is. Also all credit to Harwood's who have proven to be a very good dealer indeed.
Do let us know how you get on when you revert to Halfords finest.
Regards
Brian

This doesnt sound promising since mine has the Halfords fix and is in for "proper strap" replacement this week under warranty - I've asked them not to throw away the Halfords strap just in case. Coincidentally also have E Pace as courtesy car.

Hi Brian.

Blimey. What are the chances of us both having exactly the same experience with this in the same week ?

Yes, I too was disappointed (understatement). The problem is that Jaguar technicians must all be deaf. Seriously, can they not hear it ? And that it wasn't doing that before they removed the temporary fix ? They should have said to you "we've changed the strap sir but it is still making the noise". But I'm sure they didn't. Mind you, when I first took my car in for them to listen to it they said it was "normal" so what hope is there really. I mean, it's really loud. Especially when you tune into it. I began to wonder if it was me, and maybe they really do "all do that, sir" until the Halfords fix. I still think my dealer might not get it - and might think I am a bit 'special'.

I too assumed the taught-ness of the old strap was the issue - and that the 'floppier' new strap would be better. That it is still not better is a complete mystery. I'd love to get a factory NVH bloke to have a listen. Re-fixing the Halfords strap (which my dealer kindly left in the footwell for me) will simply add more slack but if it has worked (again) for you then hopefully it will again for me. I too will call it a day at that point. "if the fix ain't broke don't try to fix it" type thing :lol:

Actually, the fact that your situation is exactly the same as mine give me some solace in a "thank god it's not just me" way !

 

[BRC]

Really quite bizarre when you think about and as you say what are the chances! Hopefully you'll achieve the same result as me and we can both be content with our lot.
Interestingly I've often had the same suspicions as you in regards the possible hearing loss suffered by technicians and might I add sight loss :lol: In all fairness I think it is sometimes down to world weariness and I'm sure it must be difficult to maintain 100% commitment day in day out. Please don't get me wrong here because I think Harwood's Crawley have been exceptional in their approach and I do believe this noise is heard more so by a regular driver. My son thought it was all in my head but conceded an improvement when I initially changed the strap but I still had the feeling he wasn't entirely convinced. Have to say he's a technician albeit not in the motor trade so perhaps that is the explanation!

 

[Pongo]

It will be interesting to see what happens with Steve's fix this week. Hoping for his sake he doesn't make it a 'hat trick' of failed fixes.

I do wonder what Jaguar would say having paid for warranty work that hasn't solved the issue ?

I took my friend, who is an engineer, out in mine when I first bought it to demonstrate the noise. For the first couple of minutes he couldn't hear it then he suddenly tuned in and was firmly in the "that can't be right it's bloody terrible" camp. Which was a relief. As was the Halfords fix as that confirmed I wasn't going mad !

the fix ......pictures.....https://www.xeforums.co.uk/viewtopic.php?f=19&t=6351

Wish I had commision from this and Halfords !!

:lol: :lol:

 

[Pongo]

Was driving along this morning listening to 'the' noise and thinking whether it sounded like a sewing machine.

Then it occurred to me. Mine sounds more like a rattlesnake on speed (and, indeed, at speed). Which is ironic as with this issue Jaguar are taking the python...

Just thought I'd share that :lol:
