Hi David, a battery drain over 3 - 4 weeks on a late model XKR is NOT unusual due to the quite high quiescent current that occurs on modern cars due to all of the background modules "humming away". I assume that you are aware of the "double lock" facility on your car? When locking the car, press the lock button on the fob twice in quick succession (it will then beep at you) and this put the electronics "to sleep" after a few minutes, meaning that quiescent drain is as low as practical. In addition, the fobs should be stored in a suitable location - a Faraday Pouch, or Box, is best, but in any event at least 20ft / 6m away from the car if simply left on a shelf / key hook. This stops the car from "seeing" the keys and coming / staying awake in anticipation. I am familiar with the C-Tek unit, but my preferred smart charger is the Ring Automotive RSC 612 unit, which works specifically for 5.0 litre engines. These do so much more than just charge the battery as there are test functions as well, plus they are suitable for AGM batteries on stop / start enabled vehicles. I have several of these chargers and leave them connected to the vehicles long term - like all over the winter when the Jaguar does not poke its nose out. One very handy function is the LCD screen which indicates the state of charge / condition of the battery as a percentage. These Ring Automotive Smart Chargers are not cheap at circa £100, but in my view they are worth it. N6 JMX

Understand about main dealer labour costs and was not indicating that's where you should go, simply asking about what your handbook states about the various warning lights. Without fault codes from Jaguar specific diagnostic equipment, there is not much else can be advised but wait and hear what your independent says about the investigation. Sorry. N6 JMX

Hi David. If you can't leave the CTEK connected I presume yo would not be able to leave another charger connected either. Your CTEK probably needs more than a couple of hours to properly charge the battery and if it is going flat in 3/4 weeks a "beefier" charger would probably not help anyway. I would be looking at a solar charger to keep it topped up whilst you are away. Just make sure you use one with a maintainer module or it could overcharge the battery. https://www.autoexpress.co.uk/product-group-tests/43793/best-solar-chargers-car-batteries-2023 The other, longer term, fix is to check your car does not have an excessive quiescent drain such as an internal light staying on or one of the many computer modules failing to shut down properly John

Pretty good chance it is the MAF sensor

Aready have a CTEK but need to buy a decent 10am or larger battery charger as found battery flat after 3/4 weeks away - not happened before as when away 3/4 weeks three times a year it’s always started first time and I’ve just used my ctek to boost it up for a few hours before using again Cannot leave CTEK on whilst away Car is a 2012 v8 XKR coupe with 26k miles and good Varta battery 2.5 year’s old thanks

Thanks for the reply. He had diagnostics but, not the specific Jag ones. That’s how he thought that it could be a solenoid in the Turbo. No previous warnings. l only drove it as far as the nearest Lay By. I notice that there is some references to ‘actuators’ on this site and, that sounds a possibility. No black smoke. From previous experience, the garage it is booked with is reliable but, the Jag has never been to them. Reluctant to go to Main Dealer due prohibitive labour costs

Did you get any fault codes from the Green Flag folks? Do you have a code reader to plug in and read the codes stored yourself? A red light usually means an immediate stop and investigate, whilst an amber light means stop, investigate and limp home, but don't set off on any long road trips. What does your handbook say for the warning lights? Presumably something like "Consult Main Dealer". N6 JMX

Hi l have a 2014 2.2 XF and was overtaking on A34 when Red Warning light came on and, speed Dropped from 70 to about 15. Green Flag eventually turned up and diagnosed problem with Solonoid in Turbo. 150 miles from home, car had to go on Low Loader. Amber Engine Block warning now on as well so, not driving at all Trusted Jag specialist sadly retired so, booked in with recommended non Jag Garage for 20/5. Does this diagnosis sound right and, what sort of cost am l looking at. Only 33,000 on the clock as retired. Thanks Dodge

Just my luck, non in stock at present but we will get there, car still driveable just getting a shudder at 50-60. You would think that all the shafts / bearings are the same circumference 2008 - 15 wouldn't you Regards Peter

Thanks Big John, There are several listed which is a great start I have emailed them for the correct fit to order. Interestingly, even the prop shaft repairers say they cannot get hold of the right item themselves. If it eventually proves good, I will pass on the details to those I have asked to do the refurbishment. Jaguar parts dept wont even provide a part number for it and obviously don't sell it as a separate item. Thanks a lot, I will let you know how I get on. Regards Peter

I am in the process of removing the A pillar inside trim on my 2011 XK, left hand drive model. After researching the process to remove the trim it seems that it should simply pop or pry off if necessary. The bottom of the trim seems to be loose but the top absolutely will not release. My car also has the microphone mounted near the top of the trim panel. Is the microphone attached such that it is keeping the trim from releasing? The microphone has two rivets attaching the back to something behind the trim. It looks like I may need to drill out the rivets to release the microphone and the trim. I wonder if anyone has experienced the same problem. Thanks in advance!

You’re welcome, Paul. If you intend to remove the battery then always the negative first.

Thanks again Jim for your helpful advice. By the way, do i remove the neg or pos lead from the battery?

I have been thinking about it and still think the problem is a jolt to a rotating part is setting off a resonance. But that requires sufficient freedom of movement to allow the parts to physically move so if it were the propshaft there should be play in the bearings / their mountings or the rubber / Universal joints themselves. Likewise in the driveshafts but the driveshafts do hve a built in abilty to move vertically at the wheel so possible more likely??? Do let us know how you get on. Good Luck.

It seems that the centre bearing for the prop shaft on the XF model is unavailable even from main dealers, except as part of a full prop shaft which they will happily sell you at Circa £1,303 plus VAT Such items are available for other Jaguars and for most other car models at costs ranging around £40 or so. This seems like extortion on the part of Jaguar (If Jaguar can get them surely someone must be making them, any ideas or leads?)

Prime suspect with these symptoms is the key itself - if you have a spare key, try that before anything else. There is an RF-ID chip inside the key, these can fail at any given moment in time with no warning. If they do, the car will not turn over. Also try locking/unlocking several times in a row with the remote fob.

I know this is and old thread but I hope someone can still answer my query. Does my year 2000 S Type have any form of PATS or immobiliser ? I ask because my car will not start - all the electrics work but the starter does not function - not even a click of the solenoid. The car was left unused for several weeks and the battery discharged itself and I have been advised this could have caused an immobiliser e to function. If so how do I reset it??? Thanks Steve

I was born in Poland hence S100 bring back many memories as it is somehow similar to what I used to see on the road on a daily basis. Although I never owned one, my father used to drive Fiat 125p and later on FSO Polonez Caro which was hell of a clunker. The comparison to the Tacoma narrows bridge seems to be spot on to what I am experiencing! There is a high chance you are right with the propshaft. I will have it checked too and will post the outcome in case anyone else had something similar in the future. Hopefully it will not end up on a whole propshaft replacement...

Hi Paul, With your car there is no problem with disconnecting the battery as you don’t have the BMS (battery monitoring system) fitted. I have the icarsoft i930 for mine which is perfect for what I want and it will tell you which sensor is at fault. If you go the icarsoft route then make sure you buy from a reputable source and it is Jaguar specific.
