Hi, My 2015 XJL has developed an intermittent problem of on occasions it will not turnover and start. This appears to be linked with opening and closing the boot as the non-starting can occur after I have placed something in the boot and sometimes can start after opening and shutting the boot. Recently the engine stopped when in traffic I pulled into the side of the road to allow oncoming traffic through…..the ECO stop start stopped the engine and it refused to restart. I opened the boot using the switch on the dash, got out of the car and closed the boot, got back into the car and it started. The battery is new and has been coded into the car. I have had the boot latch and starting motor replaced and the problem exists. Earthing appears to be OK. My local Jaguar dealer can not find the issue and neither can local auto electricians ? I am at my wits end !!! Have any of you guys come across this issue and advise me how it was resolved.

You're welcome, good luck with whatever you go for.

Thanks for that, I'll have a look at this.

First thing that springs to mind would be this : https://www.ebay.co.uk/itm/357133847843 There are cheaper Chinese units available, i picked that one to give you an idea whats available. My own S Type is a 1999 model so has the older style dash and no "off the shelf" option so i bought a dead stereo with the right colour surround and built a 9" Android unit into it - i must finish the job and get it fitted!

I have a 2006 s type which I've been told you can't update the sat nav later than 2012. Does anyone know of anything I can do to solve this issue? It runs on a dvd .

Finally solved map upgrade issues. Jaguar where excellent 🏆Lloyds jaguar Houghton le spring did themselves proud with a little backwards and forward. Dropped of car 8 courtesy car, washed, hoovered returned by 4 . TCU &IMC update. Now my car is talking and I can update maps and live coverage. Cost was bearable, experience sometimes frustrating but a positive outcome

Dark blue, oatmeal interior. 67,ooo miles. Very nice condition. I have owned for two and a half years, doing approx 6k miles a year. It is a very good car for £8,000.

John, Thanks for your response and advice. I shall give it a try! Mike

Hi Mike I had exactly the same issue on 2013 XF Sportbrake. Totally confused the garage as not fixed after replacing the external sensor. It seems the computer still relies on previous readings until the car has been turned off for over 6 hours so, fingers crossed, it may be OK when you have left it overnight..... Good luck John

Very confused ? How did you manage to buy a new I-Pace in June 2025, as dealers, we had to register every new Jaguar we had by the end of October 2024. Every new Jaguar includes 3 years roadside assist anyway (which is administered by the AA) as part of the manufacturers warranty package.

As i always say, it's better to have it and not need it than need it and not have it. Even new cars break down and the cost of AA cover Vs the cost of an enforced motorway tow is comparatively nothing.

I bought a new I-Pace in June 2025, the AA are now asking for a renewal fee do I need the AA on a new Jag?

Hi thanks for that it has given me a guide line

Hello, I don't know if this helps. I live in a small village just outside of Bristol, and my local village garage changed the timing belt, water pump, etc in my car, the same year as yours at the start of the year for £1063.

Hi all, I’m the owner of a 2010 XKR 5.0 Supercharged. The outside temperature on the infotainment screen flashes between ambient and -40°, when this occurs the HVAC fails to operate (including the blower). Occasionally the issue resolves itself and everything related works as normal until the car is restarted. Battery has been replaced along with ambient air temperature sensor (nearside door mirror). I would be grateful if anyone in the group has experienced/remedied this before I go down the diagnostics path. Thanks in advance, Mike

Have a look on this page for the correct VIN range, then with the part number just google it for suppliers; https://parts.jaguarlandroverclassic.com/parts/index/part/id/400.1293.3744.16495/brand/jaguar/

Hi Michael Seems you have no fuel available at first. Sounds like a problem I had with an old Peugeot 208 where there was a loose connection in the fuel line to the pump allowing air in and thus letting the fuel slip back down the line. This needed prolonged turnover or manual pumping of the fuel pump (it had a primer on top!) before it would start. Obviously the longer it sits between "sessions" the more time the fuel has to creep back down the fuel line if that is your problem I would check the fuel lines for leaks / loose connections and look / smell for fuel leaks and possible areas where air could be getting in the line. Good luck John

Hi where can I get the engine under tray that goes between the front bumper and main under tray that protects the engine. Also I need a n/s splash guard that goes over the wheel and bolts to the front bumper. Hopefully I explained this correctly. Thank you

Hello Justin, The SDD/Mongoose that I have I presume is a Chinese clone. The suppliers said that it must not be connected to the internet or it will not work. Therefore when I try to use it, it has the Red notice in the top right corner saying servrt fault. Is this normal?

I wish that someone could tell me why the SDD diagnostics won't read the data on my car

Joe, if and when it starts, it starts without hesitation and I can drive for an hour, have a cup of coffee then it will stat again and drive home so I can't believe that it is air in the fuel system. It is as if the injectors are being inhibited

Yes, glowplugs are working. If I use easystart it will fire but not run. Injecters are being inhibited but no DTC's showing

Hello John, Battery full, turns over rapidly with easystart it will fire but not run. It seems that the injectors are not being activated

I think you may be right there - especially in America where the Jaguar brand adoration is huge. It makes me wonder if they bowed out (disgracefully) to avoid having to enter the EV race with no actual intention of producing such models knowing that the outcome would be negatively received (especially in the US market who love their huge V8 engines). If that is the case then it was a very wise move on their behalf - watch everyone go down that path and fail then re-enter the market with a much better solution?
