Having worked most of my life in electrical/electronic engineering, I can confirm there is nothing more frustrating than having to write on the job sheet "NFFAT" - No Fault Found At Test. Over the decades ive had many "Intermittently Intermittent" faults as i call them. Sometimes it's has been a long and extremely annoying process to find the fault and often when i do, i find it's a "Compound Intermittent Fault" - one where two or more problems contribute to not only the intermittent fault but the overall intermittency of it occurring in the first place. I wish you and your autoelectrician luck with finding it, you may have to lose this battle to win the war and come to an arrangement with him whereby he comes to you when it faults to investigate. This isn't just a "Jag thing", it happens to all makes and some are much worse than others! 'Tis the nature of the beast with electrical/electronic systems sadly.

my XF in a nice wooded are on the day i bought it. Then at home after fitting a chin splitter. She looks mean.

Hi all. I have what I consider to be quite a rare Jaguar. Because I can not find many for sale. I have a XF sportbrake AWD 240hp twin turbo 2.0l diesel. I love it. Its huge, massive load area, very comfortable, almost economical ( just over 42mpg) and well equiped for a R-Sport.

Thanks for advice.

Hi Paul, this website may have the information you need or even the tyres; https://www.longstonetyres.co.uk/classic-car-tyres/jaguar/xj40.html

Thanks

Many thanks for the suggestion but doing this is beyond my own skill level! I will let a Jaguar mechanic have a go. Dennis G

Hi Colin, you indicate your problem is with the X-150 model, but your profile descripting infers you have the X-100 model from 2001, need to clarify which model you have the issue with. Before you changed the battery, did you have any need to jump start the car? If yes, then you may have fried the video screen that is the display in the X-150 model. N6 JMX

Hi Thanks for your response. I have had the same issue with either of my keys and I have replaced the batteries in both. I had a new drivers door latch fitted as well as tgd new boot latch. One garage told me it was the gear selector unit, so that was replaced and the problem still exists. It is with an auto electrician at the moment but it starts every time he tries, so no fault appears on the diagnostic……. Soul destroying !

Check the internal contacts are properly connecting within the key fob, they are a bit fragile and easily bent away from the contact face. N6 JMX

Hi Andrew, welcome to the Forum, hope it all goes well for you. In future, you may want to post your questions in the correct area of the Forum. This post is in the X-type area and you want to be posting future requests on the 1999 XK8 in the X-100 section, a bit higher up the page. N6 JMX
