Strange. If it sounds external it can't be a sensor and is more likely to be a bushing or some type of joint.

Could it be that bird you ran over? It is haunting you.

Good luck Monday. I'm interested in finding out what it is. Please let us all know.

 

The mechanics had hoped it would be a brake or strut - but they called and said they did not find anything wrong with those - they said this morning they were going to hook it up to a computer as well as converse with techs in Great Britain at the same time. So far....no answer...

the Jag dealership was dumbfounded (sp?) by my "rear chirping" XKRS.

They called UK Jag for advise and they told them to replace the struts and springs (First).

Not sure how it could ride SO WELL with having bad strings and struts (?). I was hoping they would find a bad break, break sensor, or some other malfunctioning sensor. My jag is back in my posession and is in the garage. Very disheartening to think they are just going to replace parts without knowing for sure what is wrong .

But...they are trying.

The good news is it can't be anything seriously wrong with the car with it performing so well. It's a pain (chirp) in the ***.

I'm surprised the Jaguar technicians couldn't figure it out without going through a rather unsophisticated process of elimination by replacing parts. With all of their equipment and knowledge you would think they could have simulated the chirping situation with the car on the hoist or in the work bay.

The bad news is it kind of takes the shine off your new pride and enjoy until they get it fixed.

Keep us posted on your progress.

 

The shine... Is dim

They have ordered a "noise kit for struts and coil sprins" on the invoice... What is that?!?

 

Have you tried, to ask a jaguar tecnician online the question, it 's not expensive and for 20$ maybe you will find your answer and can talk to the dealership, there I guess they do have a long experience with jags or if not they do contact specialist, I will not hesitate if I was you for such car.

Maybe he can be of any help with Alan too and his jag.

 

I tried justanswer, and "Richard" was the one that *tried* to answer my question. The only thing he did was copy and past info from the manual...he doesn't know as much as we do on this forum.

I guess it would be fine for the totally clueless...

 

I have on my invoice that the dealership contacted a jaguar technician and gave "No Advise"

I saw that and about fell off my chair!! Really? No advise????

I live in Ohio... This car cost a house! If its not fixed that tech will be seeing it in the UK as they ship me a new one! Tested not to chirp!!

 

That's strange that a technician could not offer *some* advice...

So, what components could cause this sound.

Firstly, it has to be something that *moves* against something else. And, are we safe in asuming it is coming from the rear area of the car?

If so, then the components that could be causing the chirp are limited to the moving parts of the rear area of the car.

Also, Lothar ( that name sounds medieval) says that he (I'm assuming they are a he ) has made the sound before just by getting into the car - is this correct? So that means you don't necessarily need to apply power to generate the sound. If that is the case, that (to me) limits the systems to suspension and brakes, and possibly wheels (associated parts).

Of those systems, what "moves" when one gets into the car? To me this is the most telling symptom.

Suspension - Struts, Springs, bushings, stabilizer components

Brakes - slight movement of wheels causing slight movement of rotor against pads...emergency brake is out because it is off when car is under power and the sound can still be produced...also slight movement of axles against bearings...this is out because this would not produce the frequency of sound being experienced.

Wheels - flexing metal - can we rule out flexing metal in the wheels? (probably so)

Given the frequency of sound, the fact that you can create the sound when you just sit in the car...I think this may be caused by one of the bolts that hold the rear strut towers to the body of the car.

I think you should call the dealer immediately and ask if they re-torqued the bolts which hold the strut towers into their mounts!! Top and bottom!!

(but seriously, I do think these are suspect)

 

Can it be recorded and sent to a few UK service managers.
while I have the xj problem, jag france will tell me an expert is available week 52? we all went through some frustrations.
Those able to diagnose it are the service managers in garage where there is a bunch of these cars. Coventry, London etc...

and the the noise kit did not helped? they have not changed the struts yet?

For me it is maybe a front control arm like this service manager at Strastone has diagnosed for me by email but they can replied to all emails in regards to your sale and dealership etc...if you wish his email, please pm me, he may not be very happy I do so, but of course I will do it for you as i feel bad about it.

 

Thank you all for your wonderful posts!!! You bring hope to my soul for the human race... My name is Ryan...Lothar was a character on Warcraft PC Game long ago!!! I adopted it in my mind as a user tag back when Internet gaming was but a weee pup .

Now then my invoice says they re-torqued everything... The sound was still there... So they ordered struts and coils to simply replace them. They said it was inconsistent so they could not localize the chirp. I put it in reverse today and heard a few quick "chip chip" high pitched noises from the rear. it's oh so frustrating but I love the thought process rscultho!!!!

 

I hope they will fix the problem asap, I will be very stressed myself selling a car with that chirp to a person like yourself, and will do all I could to have you satisfy very rapidly!!
Indeed I feel really sorry for you and i hope its fixed quickly again.
Is it how you should be rewarded after encouraging the brand so well?

Me since you said it was an electrical noise and that it can appear when the ignition is not on, I thought about the alarm when the vehicule is tow away, or one of his sensor. if it is a metal noise, i know the silencer goes bad after a while and some parts could be moving inside but probably not with a new one. It does not encourage new xkrs buyer.

Maybe Jaguar need to review his computer system and each repair resolution should be reported and easy to access for all service managers, instead they are going the rough way from scratch for each individual repair, they lost time and money and they built customer frustrations.
I bet you this problem has already popped up somewhere but nobody can find it.
I hope its not your exhaust valves that are already oxydated that you can hear. Re aluminium body resonances, don't under estimate where the noise could come from cause indeed its rarely from where we expected it.

 

If this had happened at say...80000 miles... I might understand....500 miles? You are correct Jagxk2008.... Totally flustered. Then again warranty goes out at 50000!! least it's 4 yrs if I don't drive it 50k.

Meant no disrespect on the name...

Well, if they replace the struts and associated hardware and the chirp goes away then all should be right with the universe once again. I would insist that if they replace the struts they replace *both* struts, even if the chirp goes away after replacing just one.

 

Actually they are not replacing any strut or coil... They ordered a "noise kit" for it...anyone ever heard of a NOISE KIT!!?!!?! That sounds like patch up work to me... Not to happy here!!!

 

I had initially misread the invoice... Didn't see the "noise kit" apparently they said nothing was wrong with function of car...and I'd agree it drives and feels great apart from chip chirp chip!!! That being said they also said they failed to localize the sound or find the cause "for sure". uuuugh! I just want what I paid for... A new car with nothing wrong with it!!! I wonder regardless if some concessions should be given to me for this stress... Warranty extension in miles and or years... Definitely going to be gun shy about buying another Jag...sorry so say...

Loth

 

Pierre the Jag tech messages me back... Said the problem is not common and they have not heard of it... Discouragingly he said it sounds like its going to be hard to localize and figure out!!

 

I am really sorry. What can I say, can you record the noise ? did you email other places ?
Well, when they will try this noise kit, soon?
I am confident they will end up to find. But yes they stressed you out. Really sorry again me too my feelings are broken, and I feel a bit weird today.
Did you contacted Jaguar US headquarter, hey it won't change anything right away but at least, they are aware of your problem...damn...

Noise additive are pretty commun and works well for many parts. But is it what you need, let's hope really.
Well, use the law Ryan then. If you can not get it fixed after 3 trials just go and request it of course asap. But maybe they will find out.
Contact your attorney and call jag US asap.
maybe it is better if the attorney call them they know which words to use.
Take care Ryan.

You know Ryan, I will post straight on their facebook page in each country, Jaguar Facebook pages, nicely to report the whole thing, to see if it does interest any future buyers to know. You bought jaguar most expensive car men. I will call UK headquarters, I will try to reach the Ian Callum too, etc...try to find out who is the US manager for claims or a top guy and bypass the customer stuff there....We should not be here only to post success story...

Down on the road you are going to help a bunch of people including those folks at jag who read our theme. If you can be firm and keep cool, ( not like i do when I am stressed and speak another language i got stressed out pretty fast on the phone, at their advantage) the firmer you are, the more respect you got in return. Just go and call pots of facebook. And hopefully the chirp will be resolved soon with more attention too. But you know all those things. The stress .. you know....

The whole story sounds like, we produced the car, shipped it overseas, so now its your problem...it is simply too easy.

How many miles the car had before the sale, a few? 10, 50? more...Who knows they were well aware about it. Not to stressed you out. How you describe it i have an hard time thinking they did not know about it, and already tried in vain to fix it, how long the car was there?

 

Well, is the noise kit for *YOU*?




Earplugs maybe...

 

We can laugh now but all I can see is Jaguar loosing a lot of credibility if it remains in the next few weeks. It is a tough theme. I am really touched by the situation cause i trully weight, what car producers may have forgotten, the enthusiasm you really put into it, there at jag, its a different angle for them, indeed you are the leader Lothar52 there is no doubts.
