Thanks John. Food for thought. Sadly my Jag must have suffered at the hands of a previous owner as evidence of a repair is now showing on the rear nearside flank and bubbling is showing on the door reveal. The engine runs well at the moment and the transmission shifts smoothly. I think I will have to play it by ear and just deal with any issues as they arise. No doubt I will post on here if anything happens.

Not on a XF. Sorry but it would look wrong methinks.

It's been a while since I last posted what with having a stroke, then the pandemic and the car generally behaving itself and not giving me reason to ask any questions. However, a friend of mine who is in the trade recently advised me to get rid of my beloved X Type. His reasoning was that he would expect a DPF service to crop up soon and that is expensive apparently. Also, the car has done 144k without a transmission fluid change (was advised by gearbox specialist not to change fluid) so is apparently ripe for failure. He reckons that, with second-hand prices so high I could get back what I paid for the car and avoid some expensive bills. It sounds logical but I am very attached to my Jag and would like some input from other owners on the situation. Are there cheaper ways around any of these pitfalls? The car is running fine at the moment (touch wood) and I am now doing fewer than 10k miles a year. Any thoughts gratefully considered.

Alas no scan tool. My local garage will probably do it for free (or for a beer or two). Any idea of ball park cost of fix? Sorry for delay in replying. This is my third attempt. Phone kept accepting response then losing it!!

So I have enjoyed a couple of months of relatively trouble free driving if you discount the low speed gruffness and hanging on to the lower gears for what feels like too long. No stalling, no limp mode. Until yesterday when I pulled out a side turning and yahoo, there 's the limp mode indicator and Gearbox Fault flashing on the dash. Now I know that every other fault has not ultimately been down to the gearbox but the car's recent behaviour set me to wondering. I recently heard about an Omega which had a range sensor fault which was causing similar symptoms to mine. Obviously I will have to go and get it code read again but does anyone want to advance any theories on whether I am barking up the wrong tree?

Yep. I was trying to drive it hard before the limping and stalling. After that I had to drive like a pensioner in a Micra in order to keep it running. Now the low fuel pressure has been sorted I can be more enthusiastic with my driving. It's hard to exceed 2k revs in normal traffic though. And the car is still gruff at lower speeds. It's still not 100%.

So the diesel specialist couldn't find any problems with injectors or fuel pump. He did find milky diesel and debris in the fuel filter. Somewhat surprising as the filter has only just been changed. He has advised me to avoid supermarket diesel and see how it goes. The car is pulling well with no trips into limp mode at the moment. He also commented it was one of the sweetest X Type diesels he'd encountered. Not what I was expecting to hear.

My mistake. When I read the header I thought it meant bang up to date. Pity the discs aren't interchangeable between models.

Just took a peek and the blurb says it's a 2012 disc. Am I missing something here?

I've noticed the same disparity in speed readings. I am guessing that the boxes aren't calibrated to the same level of accuracy as a speed camera. Having said that, they usually agreed with my Mazda.

No, but I can tell you from personal experience that thumping it doesn't work 🤔

I think 251 is injectors. Have you done a leak off test?

So I took my troublesome Jag to a transmission specialist to investigate the problems with holding onto gears at low speeds. He says the box is fine and the problems are caused by low fuel pressure. Took the car to my regular garage to check pipes etc and nothing is loose, leaking or misaligned. The car is absolutely fine tooling along at 70mph. The problem arises whenever I accelerate using more than a featherlight touch. The car either stalls or goes into limp mode. I've looked at online and there are all kinds of horror stories out there about pumps, injectors and fuel rails. I accept that it could be any of these things but I can't believe the car would run so well if something major was wrong. Anybody had a similar experience?

So I took the car to an AT specialist who tells me that there is nothing wrong with the box, it's responding to an engine problem. Apparently the fuel pressure is low and sudden demands on power (rapid acceleration) can stall the engine (this happened to me twice but I mistook it for limp mode with an added twist ). He mentioned the gruff engine note and when I said that it started after the steering pump was replaced he surmised that something has not been put back properly, may even be the cause of my problems. He's not an engine man though so could only make suggestions. So I am going back to my regular mechanic to ask him to take a look concentrating on whatever he took off in order to replace the pump. We live in hope.

Going from bitter personal experience DaveMech's diagnosis is probably correct. My 2.2d had crud in the turbo and that's what did for the turbo actuator apparently. So you might want to get that checked out too as it is probably actuator failure which is triggering limp mode. I have invested in some Archoil turbo cleaner and fuel additive. No idea whether it works yet but their 'Oilem' blog is quite interesting and contains an article that exactly described my problem (and possibly yours). Other posters recommend Wynn's and Miller's which do the same job.
