I personally believe the water pump and belt should be done, on the basis of assuring that it hopefully does not need doing in the future. "Belt and Braces" maybe, but could also be "First spend is the cheapest spend", or "Better safe than sorry". Best Wishes and Regards, John

Mark Fortunately my problem was/is restricted to Bank 1. Every thing is still working well at the moment, having done some 500 miles now with no re-occurrence. Fingers well and truly crossed. Best Wishes and Regards, John

Nick Welcome to the club/forum and the potential expense of running Jaguars. Best Wishes and Regards, John

Charles Welcome to the club/forum. As for electrical/battery problems, these are Jaguars and you will soon grasp that they are charge hungry. Parasitic drain is very common and you will need to keep your battery in good condition and well charged. The popular piece of equipment is a CTEK MS 7 0r MS 10, Charger/Re-conditioner. I put my S-Type on a CTEK MS 7 as often as I can and certainly at least once per month. It really does stop a lot of unnecessary yellow light and messages that are only generated because of low battery charge. Well worth the investment and effort to keep battery in good condition and charge. Best Wishes and Regards, John

Thank you. Hopefully now sorted. Took readings from both Lambda Sensors on my diagnostics and the graph views showed a major difference between up and down stream sensors. Swopped the upstream (NEW) sensor for the old removed one and the graph readings came in line. Have since done some 400 miles without any codes showing. Fingers crossed. I will keep the crankcase breather in mind for the future. However, it would seem odd to me that there was a problem on the breather as I would expect that to have an affect on both Engine Banks, not just Bank 1. Many thanks and Regards, John

I agree with Tomato. Any supplier / dealer will try their best to avoid having to pay. Just be polite, firm and determined with them. Best Wishes , John

If it has ONLY done it the once I would not react in any fashion as long as it reset with turning ignition off. That has happened with my S-Type and reset by turning ignition off cured it on the occasion. You are dealing with Jaguar electronics so do not be surprised at some occasional false/negative readings. This will be especially true if the battery charge is not kept well up at all times, they seem to be prone to suffering with Parasitic discharge. I have a CTEK MS 7 (charger/restorer) that I use at least one per month, if not more, for at least 24 hrs, if not longer. It keeps the battery well charged and seems to protect from too many yellow lights or warnings. The CTEK is very popular amongst owners on this Forum and well worth the investment. I still stand by what I said about not accepting filled/sealed for life transmission fluids. My personal approach at 86K miles would be to change the transmission fluid, that is of course assuming that there is no service history/proof that it has been done at an earlier mileage. Best Wishes and Regards, John

Charlotte Good luck and hoping for the best. If not you are going to be in for a major expense. It has been revealed on this forum that others with F Pace engines having to be replaced have had some good results from Jaguar Customer Service. Best Wishes and Regards, John

Stuart Welcome. Good luck with finding the car of your choice. Best Wishes and Regards, John

Barry I do not know what mileage your car has done. If the transmission is showing any signs of not working correctly I would personally change the transmission fluid (or have it changed). My S-type has only done 64,00 miles from new but transmission fluids/filter etc, were change at 60,000 miles. I find it rather hard (being a Dinosaur of 72 years of age) to accept that a transmission unit can be sealed for life ???????. Surely the change of fluid is going to depend upon how/what/where etc, etc, the car is used for. Best Wishes and Regards, John

Barry P0781 OBD-II Trouble Code: 1-2 Shift Malfunction https://www.yourmechanic.com › Articles P0781 code mean there is an detected problem within the 1-2 shift function often due too internal blockages or failed transmission parts. Regards, John

Charlotte Best that you thoroughly read the above experiences and then deal direct with Jaguar Dealer (or ultimately Jaguar directly) in a calm, firm and polite manner to start with. If it becomes necessary you will have to ramp up your mode of approach and quote any relevant consumer laws as appropriate. I am not aware of any warranty / guarantee that you have from the selling dealer and you have not stated how long ago you purchased the car. I believe all of this will become very relevant in any negotiations over who is paying for what. Good Luck and Best Wishes . Regards John.

Garry It may look good and if you feel it does, then do it. After all it is your car and your choice. Regards, John

Halfords sell a full kit to do the re-gas job yourself. They will also do the job for you while you wait. Best Wishes and Regards, John

Jerry I do not go along with long term transmission fluid. Personally my S-type Sport, 2.5 was done at 60,000 miles. As for DPF, I in my opinion do not feel DPF regenerations are that expensive. Admittedly "expensive" is a subjective issue. You seem to think a lot of your Jaguar (as I am mine) and I would not think of selling my car. It has done 66, 000 miles form new and I recently had to replace Catalytic Converter which had died due to a misfire I had, also at the same time fitted all new plugs, all new Ignition coils, new Lambda sensors and new inlet manifold gaskets. The total cost me around £1200, which I did not feel was expensive. As for getting your money back. Yes used cars did rise in value, mainly due to certain new models not being available. Having a son in law who is a sales manager at a main agent, I am informed that the price of used cars has peaked and is now dropping again. Surely your decision has to be based on being able to afford to buy a new car along with any desire you have to keep your X Type which plainly you think a lot of. Good luck with the decision and Best Wishes, Regards, John

Garry Sorry to disappoint. I am one of the old codgers that promotes original. The XF did not have a "leaper" and certainly not black. I will not even fit one to my S-Type because they were not fitted as original and that is how I attempt to keep my S-Type Sport. Best Wishes and Regards, John

Ross Did you report the dead battery to the dealer and ask him to replace it as the car was sold to you as having a new battery. Parasitic drain is quite a well known problem with Jaguars. The best approach to it is to purchase and buy a CTEK MS 7 or 10. Being a very well used charger and re-conditioner by many Jaguar owners. I have an MS 7 and use it very regularly for a minimum of 24 hours , often longer, when ever I am not using the car. It does seem to be the answer to the problem and solves many of the yellow warnings and codes that readily appear once the battery gets slightly low. Best Wishes and Regards, John

2.5 V6 Regards, John

Paul I am a great believer in oil / filter changes every 12 months, all be it my S-Type only does around 5,000 miles per annum. I always use a premium grade oil of the specific Jaguar recommendation. Best Wishes, John
