Jim Thank you very much for the information. How simple things can be when you know how. Regards and Best Wishes, John

This is going to sound a very silly question I am sure, but I cannot resolve the issue. The 6 disc stack player on my 2005 S Type 2.5 V6 appears to be running at all times when the ignition is turned on. Even when I am using another screen than the Audio Screen, if I turn the wheel that controls the volume level the disc is playing. This concerns me a little as it suggests the CD`s are constantly being played. Am I being an idiot (careful !!!!!!!) and missing something, somewhere as I cannot seem to be able to turn the CD stack OFF. There surely is an on/off switch to prevent the stack system from continuously working. This old boy would appreciate an answer to the problem and can put up with a rude comment if it is needed, as my daughter often tells me I am a Dinosaur. Many thanks and Best Wishes, John.

Hi I bought a low mileage (61,000 mls) 2005 S Type 2.5 V6 Petrol Auto in April this year. In fabulous almost pristine condition. A good service history, although not had a lot done to it other than regular servicing and had all MOT`s. It was MOT`d for me before collection with no defects noted or advisories given, (a clean sheet). In my opinion I feel it is able to be classed as low mileage for its age, I have had to do a couple things in the reasonably short time of owning the car and only completing some 1000 miles in my ownership. Insisted with my purchase that the gearbox oil and filter were changed as part of the deal and this was complied with. 1/ Have replaced all six plugs and ignition coils. The only fault was at No.3 cylinder only, but whilst manifold was off all six plus and coils and manifold gaskets were replaced. 2/ Am currently attempting to get to the bottom of a Code No: P0420, relating to Cat reading below expected level on Bank 1. Have replace Upstream Lambda and yellow warning came back. Am now about to fit a Downstream Lambda in the hope of curing the problem. Used genuine Denso on both Lambda`s as these are original Equipment by Jaguar. This is not a major issue to me as the cars themselves are what I consider to be the last of the traditional looking Jaguars and are an absolute delight to drive and own. I absolutely adore my S Type and would not change it for anything else. I was always a petrol head and even at almost 72 I still am. I adore classic looking cars, having owned such cars as Nissan 200`s, Nissan Skylines etc etc in my younger years, as well as a Mk2 Jaguar as a late teenager. I wanted for many years to go back to a Jaguar and did so in April this year. My personal advice and opinion, although not necessarily reflective of other respected persons on this or any other Forum, would be look for a service history and proof of mileage (like via continuous MOT`s, (if possible by the same test station) and buy what you consider is the best you can afford. I would add to that, all of the decent condition S Types now appear to be fetching good and increasing monetary values and never seem to be valued by age related prices, which of course one would not expect from what is undoubtedly an up and coming future classic. They have a terrific comfortable ride and I can achieve 25 - 26 mpg with mine. Loving it, so go do the same yourself and enjoy it. Good Luck and Best Wishes, John

Hi Joe The Upstream Denso Lambda Sensor having been fitted has thrown the same Fault Code again at 20 miles, I.E. P0420 Catalytic Converter Bank 1 showing imbalance. Have now ordered the Downstream Denso unit in the hope of that being the cure for the Code Fault. Just wanted to be sure of Bank 1: in my understanding it is the left bank as you stand in front of the car and look towards the engine (I.E. cylinders 1, 3 and 5). Thanks again and Best Wishes, John.

Joe Once again many thanks for your help and assistance. Regards and Best Wishes, John

Is it possible to see some phots please. Many thanks.

Joe I specifically purchased Denso due to your previous advice that they were OE and it was best to buy them. In fact not very much dearer than some unknown brands that can be obtained. Many thanks and Regards, John

Joe Many thanks for the warning you have given me, I know the laptop I purchased (2/Hand) has mention of DVD. BUT to be very honest your kind warning means very little to me. I am not computer technical very informed. The laptop I use in the house is running Windows 10 and I get along quite well using it, but if anything needs doing to anything my son in law always sorts it out. I have attached hereto the Ebay Link to the Laptop I have purchased. Would appreciate your taking a look at it and informing me of my fate with what I have purchased. https://www.ebay.co.uk/itm/265278849401 As for keeping the car battery charged, no problem as I have already invested in a new OTEK MS 7.0, heeding your previous warnings how the S Type can be heavy on battery power usage. Many thanks for yet again being a pool of knowledge and very helpful. Best Wishes and Regards, John

Joe Have purchase JLR/SDD diagnostics and a stand alone computer running Windows XP PRO 3 to run it on. Also as an update to previous problem with Code P0420 reading Imbalance on Bank 1 Cat System. Have hopefully cured this with a New Denso Upstream Sensor. Car has done 16 miles to far with no yellow engine warning light. "Not counting the chickens before they hatch" as when I have reset on previous occasions it has taken between 16 - 20 miles for the warning light to reappear. Best Wishes, John

Have purchased a new diagnostic as above and in fact a stand alone Laptop to use it on. Can anyone advise if a "User Manual" or "Instruction Manual" is available for this equipment and where/how it might be obtained. Any information would be useful and I would be greatly appreciative. Many thanks and Best Wishes Regards, John

Can find absolutely nothing in the way of Manual, Owner Manual, Instructions. User manual etc, etc., and any mention of Diagnostic IDS SDD JLR PRO, just produces the actual diagnostic item itself . Many thanks and Best Wishes.

It did cross my mind to get another laptop to run this diagnostics, so having read this I shall attempt to find a good used Windows xp pro. Thanks very much for this advice. Regards and Best Wishes, John

Joe Yet again good, sound and informative advice. This particular diagnostic tool apparently does not work with Windows 10 , which I have. The seller has offered to supply FOC a piece of software that will make this possible and will give continued support regarding installation and use. I feel this may be a good investment for future times and will probably make this purchase unless I get any negative reaction or advice about it. Many thanks once more and Best Wishes, John

Joe Thank you very much for your recent thoughts and advice regarding the Code P0240 and reading I am getting. You mention a IDS/SDD to plug in. Would this piece of equipment (link attached hereto) do the job of diagnosing the fault deeper/more specific. Being as my S Type is going to be a keeper for the rest of my "natural" (hopefully a probable 10 years at least) I would be prepared to invest in a diagnostic of this type if it was to be of more specific diagnosis detail than my Forseal OBD11 I currently use. https://www.ebay.co.uk/itm/223569021373?hash=item340dc089bd:g:5rMAAOSwmZBg22Ey At this sort of price it would only be twice the price of a new Denso upstream Lambda Sensor. I have been given some advice by a technician, who is a friend of my Son in Law, that I should buy a new upstream Sensor and take a chance on the fact that it could well cure the problem, which in his view is where the problem is originating. Good if it happens to be the cure, but I feel I would like to attempt to diagnose the actual problem rather than just throw new parts at the job until something works. Your obvious experience and knowledge of this model is appreciated and therefor your views and advice are likewise respected. I anxiously await your response to this post. Best Wishes and Regards, John

Forgot to give the code produced. CODE : P0420 and reads, Catalyst System Efficiency Below Threshold Bank 1.

My understanding is that there are two sensors on each cat, one forward and one rear of the cat. My ODB11 does not specify if either of these is faulty only that there is a difference/imbalance in the reading on the left bank. Other than buying both sensors (are they the same????) and changing one at a time has anyone any idea how I can identify which sensor is or may be at fault? Many thanks for this informative reply. Regards and Best Wishes , John

Russ The yellow engine light has come on again and it is the same as before (18miles done). I.E. Left Bank Cat not within limits. With all the recent history explain in this thread I am surprised that it has raised it head yet again and so quickly. As is written herein there was no mention of anything to do with emissions at recent (and low mileage since) its last MOT. I have read elsewhere however that the problem may not be the actual (CAT) but related sensors, which I have no knowledge about at all. Feeling reluctant to go as far as replacing the CATs because of the very high price that they are. The car is showing no signs of any loss of performance or excessive exhaust or fumes of ant sort, in fact it is running extremely well. Any further advice from anyone would be greatly appreciated. Many Thanks and Regards, John

Russ My question had nothing to do with plugs, coils etc as they were all done about 200 miles ago and only because I had a warning about number 3 ignition coil having a problem. Although costing more, obviously, all six plugs and ignition coils and all inlet manifold gaskets were replaced with top quality parts. I do not believe in the cheapness of some of this Chinese manufactured parts that are available. At my age ( nearly 72) I have learned through the "university of life" that you only get what you pay for. If you are going to do a job, do it well, do it with quality products and it will be cheaper in the long run. I was advised because of the low mileage (62,000) only to do the No.3 cylinder. I am afraid I do not believe in this method of maintaining a classic I absolutely adore, see as the last of the true looking Jaguars and get tremendous pleasure from driving. My reason for asking was that another "know it all", (I stress nothing to do with this Forum) and I think we have all come across one or two of them, was convinced that Jaguar was totally different in describing left bank from south bank. Like, why ?????????????. Almost as though we were talking about the River Thames in London and which was the North or South Bank. The reason for establishing the correct interpretation was because I recently got a code error suggesting the emissions reading on the left bank CAT were not reading correctly. The car had only passed it`s MOT 350 miles before and had no issues or reports of any type. I am well aware of the fact that an MOT is as good as the person carrying out the test and is only truly valid at the time of the test. However having removed/reset the code it has not reoccurred as yet and I am not very likely. right or wrong, to do much about it until the car either plays up or fails an emission test. Thanks for answering my post. Beat Wishes and Regards, John
