  1. Hi Jon That does point towards glow plugs. Personally I would invest in a can of easy start and see how it goes. As long as it does actually start eventually. I had a saab 2.2 TiD with faulty glow plugs which were impossible to remove. Went for a re-con cylinder head in the end rather than having to drill them out and re tap the head. (£1k ten years ago). Good luck 🙂
  2. Does a fully charged battery make any difference? Have you tried after leaving a charger connected overnight? Is the engine turning over at the same speed it does in warmer weather?
  3. Could well be a dodgy battery. Do you have a good quality battery charger to see if it can take a charge? CTek are very good. (really worth getting one if you do not have one as the XF really appreciates a top up once a month (I do mine once a week). If not I would suggest you get a free battery check at Kwikfit as they are also a good source for replacement if it is dead. They did mine a couple of months ago for £261 but they start at £238.
  4. Hi John Normal charging voltage should be higher than that. Mine is normally 14.7 to 14.9. How old is the battery and is it an AGM? John
  5. Hi. If it was just the casing can you not swap the mirrors over? J
  6. Hi Lewis. Pretty sure yours will be a single batttery (easy enough to check in the boot). If the battery was simply changed without telling the computers, the car may not yet have realised the battery is now OK to do a restart. However don't worry as every so often the car will do a check itself by running the battery down to what it thinks is 75% charge but never below 12.2v. Once that is complete it is quite possible the Stop/Start will reappear as if by magic 🙂 If you are not doing regular long journeys I would also recommend getting a ctek battery maintainer to keep the charge topped up.
  7. Hi Cyril If you have just bought it at the garage the seller needs to sort it or give you a full refund John
  8. Hi Dave In answer to your first point I agree, that is what I said 🙂 , I woould never use it if my destination was an Airport car park! However proponents would argue that is why the cars use AGM batteries that are designed for repeated deep discharge (I don't see myself approaching the expected service specification of over 300000 starts in the next five years). On the second point, again I sort of agree. However, as I said on wear and tear, this is accounted for by the design to minimse wear. A nice little article here: https://haynes.com/en-gb/tips-tutorials/stop-start-technology-explained As I said it is a marmite issue 🙂 J
  9. Hi Ian Stop/Start is quite a marmite function. Most people love it or hate it. Potential negatives are usually related to engine and/or starter wear and tear. Most engine and starter pinion wear is at start up, however stop/start actually pre-engages the starter pinion so not really an issue. The middle position is people not liking not being in control or insecurity that engine will start again 🙂 Positives are that it does reduce emissions (the actual rationale for its introduction). If it engages you know your battery/batteries are OK as it will not engage if it is not sure it can restart the car. Personally I let it engage at least once each journey before disabling as this confirms batteries are OK. If going anywhere when car is to be left for a few days I would always disable as the XF does conduct occasional self tests of the battery which involves discharging to 75% capacity. My concern is always that id gets to that point just before I park up so instead of starting with 100% I would be starting with 75% 😞 As you may know the XF along with many modern cars does seem to suffer from parasitic drain so I only leave mine for a week at most before attaching my ctek. J
  10. Hi Rob I have just changed my main for £261 (fitted): https://www.kwik-fit.com/batteries/search/details/bosch-s5a13 They also do a 3yr Guarantee one at £238: https://www.kwik-fit.com/batteries/search/details/agm115 I got my Aux from Tanya (mine was actually labelled LR/Jag! (currently £54 on ebay): https://www.ebay.co.uk/itm/313056124925?hash=item48e3995ffd:g:VmwAAOSwy2RlMs2c J
  11. Hi Possibly due to your timing. The main battery takes a while to come back to its steady state voltage when a load is removed from it. If you unlocked the car and then opened the boot, the car will have "woken up" and started powering up various modules. If you then read the main battery voltage the car was probably drawing in excess of 10 Amps so the voltage will have dropped to 11.6v. If you then just left the car with the charger on the secondary battery that battery will have started charging. As time went on the car will have started shutting down the modules as you had not started it, but this can take quite a long time. If you then simply re-checked your main battery voltage without again unlocking the car the modules should all have been asleep, allowing the main battery to recover to 12.4v. However, 12.4v at rest is pretty low for an AGM battery so you could well be due a replacement for both. My 2013 Sportbrake is now on its second Secondary, and third main battery. J
  12. Hi. I think the above download needs a word of warning added. If you remove the DPF the car emissions will rise to a point where the car will probably fail an MOT (or other test if outside UK.). In addition a removed DPF is an automatic MOT fail.

  13. Hi Barry. Not sure on the 2018, but on mine (2013 2.2 Sportbrake Sport) simply lift the folding floor with the strap, then lift out the expanded foam cover which gives full access to the wheelwell. You should then have full access to the battery and no need for a qualified mechanic! When you connect your ctek CT5 (good choice 🙂 ) make sure the negative goes to an earth point on the car and not the battery terminal (Positive connects to the red terminal). If you connect the negative clamp directly to the battery you take the Battery Management System module out of the circuit so the car can get confused as it is not sure how much current has gone into and out of the battery.. Connecting to the chassis eliminates the issue. I would also recommend fitting the ctek extension cable which enables you to simply plug your CT5 into the extension socket in the boot without having to empty the boot everytime you want to top-up the charge (once a week). J
  14. Hi Personally I'd go for a complete replacement harness https://www.jagsparesinternational.co.uk/prodcat.asp?root=|421:424| or https://www.jagsparesinternational.co.uk/prodcat.asp?root=|421:424| or even ebay. Price looks to be around the £50 mark. Good luck John
  15. Hi Jon If it is still on its original battery it is probably due a replacement which I am afraid is not cheap as you must replace with the correct type which is probably an AGM rather than a wet cell or "normal" lead-acid battery. I would get the current battery checked first to see if it needs replacing, but then invest in a ctek. I have this one https://www.ctek.com/uk/battery-chargers-12v-24v/ct5-start-stop-uk . This is really easy to use and optimised for AGM batteries. J
  16. If your parking space is outside consider a solar maintainer, but make sure it is not just an unregulated solar panel. If money is not an object consider the Ctek Free (https://www.ctek.com/uk/battery-chargers-12v-24v/vehicle-type/car/solar/cs-free) with optional solar panel (https://www.ctek.com/uk/battery-chargers-12v-24v/vehicle-type/car/solar/solar-panel-charge-kit) but those are far from cheap 🙂
  17. Hi Welcome to the "prowl" 🙂 Best advice I can give is if you are not using for long journeys every week get yourself a Ctek battery maintainer as, as with most modern "premium" cars they can flatten the battery at an alarming rate. I would suggest an overnight charge once a week will keep you purring happily. J
  18. Hi Jaguar customer service should be able to help if you give them the VIN number Good luck J
  19. ...but it is always the Primary (Main) battery that actually turns the starter 🙂. The secondary battery is there to run voltage sensitive systems such as all of the computer modules that are liable to low voltage supply causing corruption (such as when that battery is trying to turn the starter of a big diesel engine in a stop/start). It is always the main battery that actually starts the car. The fuction of the secondary battery is to provide a stable voltage to the sensitive electronics during a stop start. However, if the car detects that either the primary (main) battery is too weak to carry out a re-start, or the secondary (little) battery is too weak to keep the computers supplied with a steady voltage, then the stop/start will not engage.
  20. Hi Paul When the car gives a double beep it is t warn you that all doors are not locked. This is triggerred when a door fails to send an "I am locked" message to the computer. This would seem to be confirmed by the fact you can set off the alarm by opening the drivers door which should be locked. If you can hear the lock trying to work in that door it would indicate that the lock is trying to operate but cant achieve a full lock. Have you tried locking the door from inside using the lever and then trying to open it from outside? Is the lock lining up correctly with the latch? John
  21. Hi Parking sensors and camera work together as a unit so if any part is faulty the whole system is shut down. This means if a single front bumper sensor does not work the whole system shuts down. You need to get the fault codes read as this will help locate the problem. When it happened to me the fault code showed the front offside sensor had failed. However fault was still present after this was replaced as the front bumper wiring loom was at fault and the code thrown will be for the failure of the component served by the faulty wiring. New front bumper wiring loom and the reversing camera came back to life 🙂. So get the codes read before doing anything else. John
  22. Hi That looks like a 16 port OBD 2 to me, albeit a little bit beaten up. Just make sure your connector is the right way up and it should fit with a tiny bit of jiggling... Regards John
  23. Hi Mullers. That is a difficult one as since the early 2000's ALL cars made in the EU (including the UK) had OBD2 with the standard 16 pin connector. Can you post a photo of your connector? John
  24. Hi Kevin Straight back to the dealer you bought it from. The fact the traction control is kicking in indicates it is not just something you are feeling but a real issue that needs sorting. Good luck John
