Help! I have already checked a lot of other messages on the site relating to Bluetooth issues but.....
I have recently bought a 2005 S type R. All was well initially apart from a stuck rear sunscreen and that was soon solved-- it was just stuck.
The car needed a service when I bought it and I had this done by main dealer. They also gave it a "health check" which it passed. I was very pleased and very large extent I still am.
The Bluetooth connection is however causing me problems. I see from many threads on this site that are not alone in this.
I definitely have a Bluetooth module. I have, as suggested elsewhere here, checked for the presence of a microphone and it is present.
I also use the model checking website, also suggested here, to make sure that my phone is compatible with the Jaguar Bluetooth system, it is.
Initially I just got the "Phone Not Fitted. This System Does Not Have a Phone Fitted" message/screen.
Then I suddenly got the telephone screen and manage to connect my phone.
A couple of days later I was back to the "phone not fitted..." Message, and no connection.
From a web search I saw and followed a checking procedure as follows:-
1. press and hold "AM/FM" and "eject" buttons at the same time
2. Then press "eject" and "mix" buttons together. On each press the system cycles through the control modules fitted. I was given the following screens: –
main 1. 0050
CDC 3.000
voic 031004
navi 1. 22. 0
AMP 2.000
it seems to me that as far as the car is concerned there was no Bluetooth fitted. This too seemed to be a problem others have had i.e. microphone present and correct, car steadfastly refuses to recognise existence of Bluetooth.
I tried another suggestion from the messageboard here. I disconnected the battery earth, left disconnected for a few minutes, reconnected it and then switched on to reboot everything.
This was successful. The Bluetooth was suddenly present. I went through the checking procedure above and, between the CDC and voic messages, appeared "phone NAI .30"
All went well for a while. I started up the next day on the phone connected. Halfway through my 10 mile journey to work however I was suddenly presented with an engine shaped warning light suggesting an engine management problem. The car itself seemed to be running fine. I left the car parked all day. I thought it would be okay to get me home, and it was, but when I started up this time I still had an engine management system warning light and I was back to the "phone not fitted etc." message.
I dropped a colleague off at his home on the way from work. I stop for a few minutes for a chat. I came back to the car and when I started up I had a Bluetooth connection again. Once home I switched off, left the car for half an hour, started it up again, and I was back to "no phone fitted..." I still had an engine management warning light.
I repeated the disconnecting the procedure and for the moment I'm back to having a Bluetooth connection and no warning signs at all on the engine management front.
It seems as though whether or not the car recognises the Bluetooth is pretty well random. Sometimes it does, sometimes it does not.
My guess (but you all really need to know that I don't really know what I'm talking about) would be that I probably have a very poor ground/earth connection somewhere within the Bluetooth wiring. I do not know if this is, or could, in any way be linked to the engine management warning light I was also given.
I think (and hope) that I don't have any real engine problems.
I definitely have an electrical problem.
Can anybody help? Any suggestions or help will be gratefully received.
The questions that come to my mind, are as follows: –
1. Is it likely that the Bluetooth problem is something simple like a poor ground/earth connection?
2. If this is likely to be the problem other any obvious (and easy to find) connection points I should try and check. I would warn everyone that I'm not at all experienced in dealing with working on cars or their electrics.
3. With this warning in mind should I just go back to the main dealer and asked them to find out what the problem is and sort it out? This is the easiest option but I suspect it could prove pretty expensive.
4. As an alternative can anyone recommend a north-west based independent Jaguar specialist which I should or could go to (North West of England that is, I do appreciate that an awful lot of the knowledgeable site members are on the other side of the Atlantic. My brother lives in Texas and trip in the STR would be a great idea but it's a long way to go to get an electrical problem sorted).
I'm sorry if all of the above is a bit rambling but it is clear that there is an awful lot of expertise available in in this community and people rightly asks as much information as possible. That's my excuse for having gone on at some length.
Thanks in advance for any ideas or suggestions.

 

Whenever you get a MIL you want to know why. Quit even thinking about BT until you find what the MIL is. You could be taking a severe chance by ignoring the MIL. Disconnecting the battery to clear it is something I would strongly caution against.

You could get an OBD tool to read the codes. Cheap and convenient.

Indy places in the UK are - unsurprisingly - listed on the UK forum.

BTW one common cause of weird things is a failing battery. They provide amps for starting but not volts for computer modules thus the weirdness.

 

Many thanks for nthe reply. The car is not moving until I get to the bottom of the problems but I will start by checking and charging the battery. Cheers.

 

If you still have the factory battery. Replace it now. As JagV8 said we have seen a multitude of off and on again problems because of the battery. And testing will not find it. Many test fine but if they are old it is time to swap it out.

So is it the factory unit or has it been replaced?

Thanks for the suggestions and help
The MIL was an O2 sensor which has been replaced.
I had the battery checked and was told it was fine but I have kept it charged up whenever the car is not being run for a day or two.
It looks like the original battery, so I think I will get it replaced anyway in line with your suggestion clubairth1.
The independent garage which checked it over suggested that there was some unidentifiable intermittent fault with one of the components in the D2B Network.
(or the D2B cabling itself though they checked those connections and said it all seemed fine).
The error codes were not always the same.
(I was given a printout with the following highlighted as far as the audio system is concerned...but there were other fault codes too...
U2611 D2B slave ECU failed to receive an alarm clear command
U 2609 D2B wake-up pulse width out of specification
U 2601 D2B wake-up line short to ground
U2606 10, slave ECU unable to initialise its address node 2
---11 slave ECU unable to initialise its address node 3
----12 slave ECU unable to initialise its address node 4
----13 slave switched into bypass mode node 5
-----19 slave switched into bypass mode (cellular telephone control module)
U2610 D2B slave ECU failed to receive a report position
U2611 D2B slave ECU failed to receive an alarm clear command

I have now bought myself a memoscan U581.

I hope that a new battery sorts the intermittent faults out. In practical terms the most consistent symptoms are that a minute or so after starting upo the radio goes dead but comes back to life within another minute (When I take my most frequent route from my home I can predict fairly accurately where I will be when it cuts out (if it does) and where i will be when it comes back on); and the intermittent failure to recognise the mobile phone, or that it has a phone fitted. I can live with these they are not the biggest problems but I would prefer to have it sorted if I can.
thanks again both of you for the help.

 

With the costs involved, I'd try a battery. You could spend 3 times it and be no nearer a fix.

For jag-specific OBD stuff, see JTIS.
For general info on OBD, see google
Most tools only see one module (PCM), which will let you diagnose things like a faulty O2 sensor. Look up codes in JTIS / codes PDF in the FAQs (same info). For the other 10-15 modules you'd need an expensive tool.

 

Thanks again for the help and comments JAG V8.
I have bought a book on Diagnostic scanners and am picking that up as I go along.
The independent garage also spoke in pretty much the same sort of terms as your comment that I could spend a fortune and still be no nearer finding the real problem.
They also pointed out that it also looks as though I am not the first to go looking for the problem / answer...there are some scratch marks around the bolts securing the DVD, CD changer and Bluetooth box in the boot which suggests that someone ahs been investigating them in the past.
A battery sounds like a good place to start. It will not cost a fortune, it cannot do any harm to get a new one so it won't be wasted money, and if it sorts things out then all to the good.
At least I have not had any more MIL lights coming up.
Thanks.

 

Have a good look in the boot & under the spare in case there's any sign at all of damp or water.

 

Well I fitted a new battery. Thought it would be a 5 minute job but the bolt holding the restraining arm took a bit of shifting (WD40 a help as ever and was enough to loosen it eventually). I didn't realise that the other end just stuck out of the bottom of the car. I suppose I should have done..there isn't really anywhere else for it to go.
I also checked the boot / trunk under the spare. Absolutely bone dry. The whole area looks almost as good as new so definitely no leaks there (it has been raining heavily here).
The battery went in fine with no problem.
Car started well and everything was working for a couple of minutes or so then I suddenly got a screen warning which said something like "communication problem contact dealer" and since then the car has consistently registered itself as having "No Phone Fitted".
So a new battery has not solved the problem but I think potentially at least the good news is that it does at least now have a consistent fault instead of an intermittent one so with a bit of luck its real nature might be easier to identify.
Looks like I will be off to the independent garage for abnother code check.
Thanks again for the help.
I will let you know what happens next.

 

It's been wildly changing humidity too which can bring out latent faults

You may have a chafed wire, poor connection or maybe a D2B cable/connection problem so could be a bit awkward to find.

The faults would only be readable from the other modules not the only module (the PCM) most tools can read. Jag tools can read those modules.

 

Thanks again for the comments.
If I get it to the independent garage (where they do have the ability to read the codes) I will with a bit of luck get some idea of the problem. I had not thought of humidity as an issue but you are right, that has been very high for the last few days. I would like to get the phone module working if I can but it isn't a disaster without it. As much as anything it just niggles away at me that there is an issue to sort out.

 

If it was humidity-caused condensation, it'll dry out gradually (er, once the lousy weather stops!), especially if you use the a/c (such as its default auto, which is on).

 

Thanks again. Climate control is is left on default auto so I will see what happens.

I just bought a 2007 S-type & was told that there was bluetooth installed. Tried everything & no phone would work. Purchased a Motorola product last week, which mounts on the visor & works beautifully with my phone. Once you synch the two, they re-synch as soon as you get close to the car. Voice activated & everything - for under $100.00. It may be a solution for you. If you want the mdoel etc, let me know.

 

Hi Doug, thanks for the suggestion. I am going to try and get the car's problem sorted but if I don't succeed then your Motorola option will be worth a look. I would be grateful if you could let me know the model you are using. Thanks for the help. (Is it the T505? I have just done a quick Google search and it looks like it might be the unit you have described).
I do not use the hands free kit often but I really had a problem on Friday and I really needed a hands free kit so if the car doesn't get fixed I will need to get an alternative sorted eventually If the one you have works well at that price then it is worth having. thanks again, John

 

Hi John
It's the Motorola Roadster 2 - around $100.00 here. I've only had it a couple of weeks but it works perfectly with my LG phone. Voice is clear & system is hands free. There's also an app you can download that will help you find your car if you park it & can't remember where I figure if that happens, I shouldn't be driving!!!
Good luck sorting out the probs!

 

You can email Jaguar or ask nicely in any dealer and they'll give you a very detailed list of what's in your car. Easy, cheap and almost 100% way to see if you have BT.

Only better way is to get a list of modules using jag-type OBD tool, but they'll likely charge for that.

 

Thanks doug that is very helpful.

 

I am just posting this to let everyone know what (I hope) is going to be the end of the problem.
I tried to book a check up at the independent garage where it has been once already to try and sort the bluetooth issue.
They couldn't help because their computer diagnostic equipment is down.
I have, as is usual, carried on commuting in the STR with a couple of days here or there of inactivity (for the car that is) so I decided to check (and charge up) the new battery to make sure it is fully charged.
On connecting it up my battery charger indicated that the charge was at 60% so I disconnected the battery and put it on charge.
On reconnecting it when fully charged absolutely everything started working. Bluetooth phone connection working fine along with everything else...(radio without dropping or any crackling, Jaguar Voice the lot.)
I do not know whether this will last but it does look as though (eventually) the new battery seems to have sorted everything.
I have no idea why it did not work first time round so there might be some connection problem or other which dis / re connecting the battery has disturbed but for the moment all is working well and it has been for the last 3 days or so.
I would just like to thank you all for the suggestions and help.
Plenty of people suggested that the battery was the problem and the idea that it should be replaced if it was the original, whatever a battery check was telling me was very sound.
If I had paid more attention to what everyone here was saying and not bothered getting the original battery checked then I might have had it sorted sooner.
thanks again all of you.

 

Thanks for following up - and it's good to hear it's working!
