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

Hi Jaguar customer service should be able to help if you give them the VIN number Good luck J

...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.

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

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

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

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

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

Really sorry to hear. I think I would be looking at a replacement engine from a non-JLR source which I suspect will cost a fraction of what you have been quoted. Just google F Pace replacement engine, there are plenty offering free quotes. Good luck

Hi Richard Where abouts in Yorkshire are you. I hate to see old cars not being cherished 🙂 John

Make sure you don't do the front windows / windscreen too dark or you will be stopped by the Police 😞

Hi Depends on what has actually failed. Does nothing work or only some bits? Is it all doors and boot/tailgate or just one or front/back? Do windows work? Kind regards John

Yes the connector the sensor plugs into is part of the front bumper wiring loom. My reading of the fault code is that it is the right inner sensor, so the one nearest the number plate on the right. I think you may have changed the right outer sensor. Good luck

Hi If changing the sensor doesnt work it is probably the front bumper wiring loom. To change either sensors or loom needs the bumper to be removed (not as big a job as it sounds but still likely to take a while!). J

On mine it was the front bumper wiring loom. Could equally be a dodgy parking sensor or a break in the camera wiring loom. The Park Assist and Camera work together as a system so if one bit stops working the car will shout at you to warn that you are on your own and Park Assist / Camera won't be working. Wiring Loom on mine was about £50 ish fitted by Jag Dealer.

Lots of short journeys, particularly with stop-start will quickly drain the battery. The cold will also be making the batteru weaker and the oil thicker/ resitance to turn-over greater. Slow turnover is because battery can't cope. These cars are basically dozens of computers wrapped in mechanics and they don't take kindly to low voltages which trigger erroneous error messages. Sometimes the low voltage can scramble one or more module so that they need re-programming but hopefully if you can get thet battery charged you chould be OK. Remember to attach the -ve cble of the charger to the car body NOT the battery terminal as there is a computer in the battery earth strap and the car will not recognise how much charge you have given the battery unless the current flows through the bttery control module at the end of the earth strap. Good luck John

Hi Phil 14.8 whilst driving is normal. Also be aware that occaisionally the car will enter a diagnostic mode and deliberately discharge the battery to 75% capacity by limiting charging voltage to 12.2v. It does this to test capability of the battery to fulfil a stop-start restart. My guess if the bluetooth monitor is over rearding slightly 🙂 John

Hi Barry. Given the temperatures this morning, battery issues would be top-of my list. Can you give some more detail on the non-start. Did the engine turn over at normal speed or was it sluggish? Have you tried a jump start? If you have a battery charger that would be my first port of call. How old is the battery? Has stop-start worked normally recently? Do you do lots of short journeys? Good luck John

Certainly possible in mine (2013). Key needs to be detected to start but once started it does not shut down if key is no longer detected, the consequences of that could be horrible.... 70 mph at nght in the rain in the outside lane of the M6! In mine you do get dashboard warning if contact with key is lost but the car continues to run. It detected the key when you started up, if the engine was still running it would continue even though the key was no longer detected and your wife drove off. If it then started up for your wife with no key present that would be diffeent. John

Hi Starting point would be a re-gas. If cooling improves when car moving it is probably due to increased airflow over the condenser. If system has less gas than required for full efficiency that extra airflow will be helping to improve the heat exchange. Let us know if a re-cas helps. John

Hi Tim The low voltage of a flat battery has probably corrupted one or more of the many computer modules which control everything in the car (hence Wrinkly's advice on using a CTek which many of us do). A flat battery during first lockdown in mine resulted in non-unlocking rear doors and non-functioning rear windows. The solution is probably to get the software unscrambled. Jaguar dealers will probably want an arm and a leg but garages with the Autologic diagnostic systems seem to be able to sort quite cheaply. I remember there is a garage in Sutton Coalfield(?) which has been mentioned here a few times but probably not viable from Cheshire as you can't get it started. I would ring round Jag specialists in the North west. Jagman in Wigan has a good reputation and I think there is one in North Wales and another in Liverpool that have been recommended here. Good luck John

Hi Obvious advice is to check oil level and then top-up accordingly. If oil level correct next stop would be level sensor but I would certainly be very wary of not sorting it ASAP. If oil level is dropping it is either leaking externally which should be visible under the car or being burnt in the engine which should be visible as blue tinged smoke. Runing with insufficient oil risks a whole host of hurt 😞 Regards John

Hi Never heard of it, or experienced it, in an XF but there is a Topix notice against some Land Rover models : TopIx details: Reference SSM72501 Models Discovery Sport / L550 Range Rover Evoque / L538 Title AJ200 Fuelmisting when filling with fuel Category Engine Last modified 04Nov2015 Symptom 404000 Fuel System Concerns Content Issue: Fuel misting may be seen from the fuel tank filler neck, with the fuel filler cap removed and when filling with Diesel fuel. Discovery Sport &Evoque 2.0 I4 Diesel (AJ200). Cause: When the fuel is returned to the tank from the engine, it is deposited into the swirl pot to maintain the fuel delivery performance of thesystem. The recirculatedfuel is hot, so it may sometimes create a mist inside the tank. When the car is refuelled,the mist may escape through the filler neck and can be seen with a naked eye. This is a natural phenomenon and can only take place if all of the following conditions are met: Low fuel level in the tank (approximately 10 litres or less). Normal fuelling flow rate. A temperature difference of 50 degrees Centigrade (or 122 deg. Fahrenheit or 323 deg. Kelvin) between the fuel inside the swirl pot andthe fuel inside the tank (Example: An engine has been run shortly before refuellingand there was not enough time for the mist tocondensate inside the tank). Action: No action required. Typically such gentle mist may form and escape the fuel tank if the above conditions are met. Hope that helps: John

Hi Michael When the car is locked battery draw should be a few milliamps. Occasionalyl you may get an error in one or more of the modules so that the computers fail to go to sleep properly and continue to draw current. As soon as you unlock the car all of the computer modules wake-up and the car is then drawing maybe 20 Amps. This is why you will quickly get a warning if you sit in the car listening to the radio without the engine running. Personally I would want to be using it more than once a week and that use would need to be a good hour run. Otherwise it probabaly would benefit from a trickle charger such as a CTek when left parked. Good luck John

Hi Mine is the 200bhp 2.2D Sport (more imposing front end) and I am more than happy with performance and economy. The sportbrake does have air suspension at the back which is pretty reliable (very for me). On mine you can hear the air pump (if you listen) running for about 20 seconds about 200 yards after start-up. Advice is pretty standard such as FSH, and they are heavy on brake discs (about 2 years life for me and I am not at all aggressive on them) but a couple of known issues are water ingress in front foot well and spare wheel well in boot. Both of these can drown the computers and cause all sorts of problems. As with the saloon low battery voltage can cause computer issues so lots of owners use a CTek battery charger to keep the battery topped up on a weekly basis. Check every thing electrical actually works. On the 2.2D cambelt cost me £600 at dealer this year but note replacement is now 7 yrs not originally specified 10. I only use V-Power fuel which does increase running costs but have had no issues at all with DPF issues. Good luck in your search
