In the old days I would have said it is probably the fuel pump. Can't think it would be that today, surely not.

 

Maybe a relay.

 

or a bomb

 

Definitely not a bomb! Now I know why you like to be known as "Whizz"!:lol:

Pekem, I'm not at all technical, but the fuel tank filler pipe is on the far side? Maybe it's something to do with the airbag, I hope it doesn't go pop!

 

On my 2009 3.0S PL, I find that if I have the stereo on and select "Aux" as the audio source, but have nothing plugged into the "Aux" socket, I get a fast ticking sound which appears to come from various places, but is of course coming from the speakers. The first time this happened it took me 10 mins to realise what it was. Could that be it?

 

I believe that the ticking sound has to do with a person or object getting too near the passenger side airbag which sets off the ticking sound. It should go away after switching off, however.

 

I'm not sure that the airbags have proximity sensors, so can't see how this is the case????

 

As I recall there was a note in my instruction manual when I had the S Jaguar. I don't know if there is something similar in the xf one though, but I'll take a look for you!!
I've checked the handbook in the interim and in it on page 26 there is a warning about the passenger side airbag front sensor which can be deactivated by leaning too far forwards.
As mentioned, I had this ticking noise on my S-type Jaguar caused by my son doing just that.

 

I am curious whether you managed to get to the bottom of that clicking noise, Toojit? I have also heard of a relay causing this noise.

 

Hi, did you get a fix for this problem? I have a 2.2d PL with the same noise. This only occurs when the ambient and car temperatures are low. The ticking goes off after a few minutes. I have had the car at the dealers twice and it has not happened for them so they could not fix it. Any advice on what is causing this would be great so that I can tell the dealer where to look.

 

I think I have experienced similar, i thinks it's the whole dashboard panel warming up via th demist vents, and creaking where it expands ? I have had similar. It goes within 10 mins. Let us know how you get on

 

No this isn't a creak its a very mechanical ticking from something like a relay, after it stops I can make it start by switching the rear window heater on. You switch a creak on/off! However this only works if the problem occurred then stopped. If it doesn't happen in the first place I cannot force it to occur. So I need it to happen for the garage. It is from the rear passenger pillar area where there must be some electronics located.

 

I agree with cjammy, definitely an electrical noise, not a creak.

I have only just seen the earlier comments that the noise may be some sort of reaction to an object in the proximity. For me it always seems to happen when there is something in the boot, however small - so maybe this can be some sort of "interference"???

I have just been without the car for nearly a week whilst the dealer investigated and tested, but NFF.

I shall test out this theory, any comments would be welcomed especially from cjammy.Thanks

 

I haven't seen any relationship between number of passengers or anything in the boot. I am on my own in the car 90% of the time when it happens. The key factors seem to be that it needs to be from cold start, temp below 8 degrees and dark enough for light sensor to have turned lights on. Each one of these may be a red herring, but t happens when this situation occurs. It doesnt need the heated rear window to be on, but if it is on when the noise starts it doesnt go away until the heater times out. I can then make the noise happen by manually turning the rear window heater on and stop it by switching it back off. so t must be in this circuit. It happens for me every morning and evening to and from work, but not weekends when I go out later in the day. It doesn't happen if I go back out in the evening, as if the residual temperature is enough to prevent it from happening. My only theory here is a dry joint on a relay that closes when warmed up. For me the problem seems to be deteriorating as now the noise switches off, but then re-starts later in the journey. Ironically it may be a good thing if it gets worse as it gives me more chance of demonstrating the issue to the dealer. I was thinking about contacting Jaguar directly if te dealer can't fix it next time. Someone at Jag must know what can cause this.

 

Now it is getting damp in the mornings the problem is back. It is so intermittent it is a nightmare to diagnose unless someone else has solved the same issue.

 

Having the same issue with my 2013 XF -- fast ticking noise appears to be coming from the right rear airbag sensor (behind the driver). It comes and goes, both on the highway and slower roads, at all temperatures. Of course it doesn't tick when I'm at the dealer. If I can find an answer, I will post!

 

Is it possible that the noise could be recorded ?

 

Yes I can record it however I was told there are various relays in the location so they need to isolate the problem to the right one. Tonight the tick ran for 10mins stopped for a while and then re-started. It seems to be getting worse which ironically is a good thing as there may be a chance of it happening for the dealer.

 

Well I would record it and then send the file to Mike at Jaguar UK CRC, see index, and ask him to pass it on to the technical people in order for them to assess it and intervene on your behalf with the dealer.

 

I see the same issue in my XF as well once when start in the mornings.. i guess this is something to do with cold weather. I have booked in my car for next week and will flag this issue with the dealer as well..

 

Great news that you can now drive in the silence you deserve. Well done to all for their perseverance.

 

Bmeddy, thank you- this is fantastic news if it works, and according to you it clearly does. This noise (as you know) is extremely irritating, and is the only issue spoiling the best car I have ever owned and driven.

I have contacted my supplying dealer and will see if they can now rectify, it may help me if you can let me know the name and address of the dealer who corrected the problem for you (so I can inform my dealer). Please can you let me know? I will also send you a PM. Thank you.

 

By all means, contact Hennessy Jaguar in Atlanta (Piedmont Road): +1.404.261.5700. The lead mechanic who solved the problem (Jack Anderson) is fantastic and I'm sure will be glad to speak with your dealer. Again, I was advised that Jaguar US issued a service bulletin on this issue, so your dealer should have access to that information. If not, call Jaguar in Atlanta and ask for Jack. Good luck!

 

Hello all members of the forum. Is there anyone else in the UK or Europe who has experienced this problem and has a resolution? Bmeddy seems to have had this resolved, however, Jaguar INC (USA) is apparently a separate entity to the UK and Europe and therefore Jaguar UK cannot link into their warranty system and take any appropriate action. It seems that there is nothing recorded on this side of "the pond" with Jaguar...crazy!
If anyone has any information can you please post this or PM me with the last 8 digits of your vehicle's VIN number as it will be recorded on Jaguar's system and my dealer can check it. My Jaguar is currently at the dealer until Wednesday.

Thank you!

 

Hi again -- has your mechanic not called my dealer at Hennessy Jaguar in Atlanta? That phone call should only take a few minutes to explain what they found in my XF and how they fixed the problem, so I don't know why they say that this has to be determined from a system's database (from which they will glean no information!). Again, the rear defrost mechanism was the source of my vehicle's problem; once it was replaced, the ticking noise went away. A phone call to Hennessy should shed all the light that's needed. Good luck!

 

After nearly 2 years and 1 month later, it seems that the Dealer may have found the problem. This morning the Workshop Controller travelled half way across London to be at my house at 6:45 am and he finally heard the noise (the last time I was this excited was when I took delivery of this magnificent vehicle).

I will update the Forum later this week as soon as I receive the car back and it is (hopefully) fixed. It seems it may be due to a cracked plastic housing channel which contains various wiring.

Whatever the the outcome I cannot praise the magnificent care and service of Jaguar Amersham and in particular, Ian their Workshop Controller.

 

This sounds like good news. Hopefully a fix at last. My car went into Sturgess Jaguar Leicester for a week before Christmas and although parts were changed the problem was not fixed. Using info from this forum they contacted the dealer in Atlanta that fixed it for Bmeddy. Unfortunately the parts they changed were the same as what fixed it for Bmeddy. Since then I have noticed a pattern that I hadn't thought of before. The problem happens daily to and from work. The first thing I do every day and night is to open my boot and put my laptop in there. When the dealer mechanic came to my house to hear the problem I had no noise. I thought this was just bad luck, however that day I would not have opened the boot first as I was not going to use the car for work. Over the past week I have experimented and only have the issue if I open the boot first. So for a quiet journey I put the bag on the back seat! Given your comments flexing the harness opening the boot may make sense as a cause.

Now I need your help. Do you tend to do what I do and use the boot before journeys? Can you provide contact details for your dealer/mechanic please. My car is going back in next week for another try. If we have a known fix then this helps massively.

 

Not so good unfortunately, the Dealer delivered my car home earlier this afternoon (I travelled to work by alternative means), and they were 95% certain it was fixed as they were sure that they found the cause.

When I returned home I started up the car and guess what........the ticking was back...arghhhhh!

We certainly seem to have exactly the same symptoms, and you are quite correct, it always starts if the boot is opened first, that was something that I had not deduced.

I will get back to the dealer and keep you posted, as soon as I have anything to report I will certainly post it on this forum. As I mentioned before, the Dealer is Amersham Jaguar.

 

Have either Amersham or Sturgess been in touch with Jaguar Technical?

 

Sturgess have been in touch with Jaguar about this. The problem to date is that they haven't been able to replicate the fault so they have been replacing potentially faulty parts to eliminate them. They actually did this by taking parts from a new stock car hoping to stop the problem. However if you can't make it happen then it's difficult to know if it is fixed. My new finding that opening/closing the boot first before starting the car is key and may give them a break through as now they have a chance of replicating the fault. So far I have had 100% success rate in making the fault occur or not by whether I used the boot first. I could never understand why the dealer didn't find the fault, but they would never have opened the boot as part of the test so it now makes sense. If someone had told me before it could be related to boot operation I wouldn't have believed them. I am disappointed Toojt didn't get a fix, but relieved he can confirm the boot relationship makes sense to him also. I will let Sturgess know that Amersham failed as they were going to get in touch after I passed on Toojt's post info.

 

Just a guess... the boot closing operation will have a means of sensing proper closure and turning off the supply to the mechanism. If that sensing system doesn't operate correctly in some way I could well imagine a relay chattering in the absence of said turn-off 'instruction'.
