My understanding is that the auxiliary only "connects" during a stop/start event to run the voltage sensitive modules and when the engine is running with the battery being charged. With the ignition off it is not connected. So you should have no problem changing it without using a slave. Having said that I am paranoid about the electrics and using a slave battery should not, of itself, cause any issues.... However when I did it I did not use a slave changing the Aux battery and had no problems. 🙂 Having had problems with rear door and window function following a flat battery during lockdown I would use a slave to change the main battery, but like I said, I am a bit paranoid about the battery.

Hi Iain. Image attached to remove the top cover but from your post I think your problem is the bottom. I think that is not removable and would need a complete replacement unit or maybe try a repair with filler and repaint? Regards John

Hi Mine is 2013 so assume similar to yours. In audio on the home screen I select My music and then on the phone start spotify and it works 🙂 if you are still strugling maybe post some images or a video so we can advise... Regards John

Hi How did you get an MOT? I thought Park Brake Fault Light aor a Dynamic Stability Control light were classed as a Major Fault resulting in a fail. Kind regards John

Just a thought as the manual is from an american site it is possible that locations are swapped side-to-side for RHD so maybe located on drivers side. Hope you get it sorted 🙂 John

Hi This is from jagrepair.com: http://www.jagrepair.com/images/Electrical/Elect-Tech All2/87 - 88 XJ6 Series III XJS Electrical.pdf Regards John

Hi Great cars you will love it. Things to look for are water in the front footwell and spare wheel compartments which are known issues and can cause expensive problems if the computers in the area get wet. Check everything electrical works. As Clive said brake discs tend to need replacing after 3 yrs or so. If it has Stop/Start make sure it works (should stop engine when you stop after warm up unless air-con, lights etc going full blast). If it does not work battery(ies) might need replacing and they are AGM so around £150 plus for the primary one. Other than that stuff you would do on any car. Check air-con blows cold, beware cheap / worn / damaged tyres, worn wiper blades all of which suggest poor care by previous owner. Good service history should reassure and I would beware of very low mileage diesels at that age as the DPF and EGR do not like a diet of exclusively short journeys. But don't let the above put you off they are great cars and I love mine to bits 🙂 Regards John

Hi Easily had on the Internet. £10 on eBay or Amazon, and if you have Amazon Prime same day delivery if you hurry https://www.amazon.co.uk/Grendle-DIESEL-MISFUEL-DEVICE-RESET/dp/B07RBX6M8S/ Under £5 if you try aliexpress but that takes weeks. 🙂 John

...and the 2.2D is either 200bhp or 163bhp.

Hi Julie https://parts.jaguarlandroverclassic.com/c2d20230-snow-sock-kit.html?gclid=EAIaIQobChMI9pOeouv48gIVyu3tCh0zGQq_EAQYASABEgIWHPD_BwE Much easier to fit than chains and hopefully would get you out of trouble. 🙂 John

Hi I use the Bridgestone Weather Control A005 all seasons (all 4 corners) and am very impressed with the performance so far (A rated for rain) but not had any thick snow to test them in yet. I also have 4 Jaguar snow socks for the next "Beast from the East" but they are still in the wrapping and have never actually needed them in the 3 years I have had the car! John

..... but only if they were originally fitted 😞 Mine does not have them. John

Hi Misfueling device has been triggered. There is a yellow plastic tool on top of the battery to reset it. Basically push it down the filler and lift Look down the filler and you will see a bright yellow flap with a symbol of a manual on it. Instructions are in the handbook or just google it as there are good videos on youtube. Land Rover has the same system. Regards John

Hi My starting point would be to read the DTC codes as without them you really are guessing. John

Hi Bill Was the battery changed in an attempt to solve these problems? If so it is possible that the previous battery allowed one or more low voltage events which triggered the faults, effectively corrupting a bit of the software which you are now living with the consequences of. Bottom line is you need to get the DTC (Diagnostic Trouble Codes) read and cleared. If it was a problem battery that may well sort it. However I would guess the most likely culprit to be an ABS wheel sensor. In order for the TCM (transmission control module) to control the gearbox it requires inputs from a range of other systems sensors, such as the ABS system which tells it how fast each wheel is turning. All of the sensors are used by multiple sytems and a fault in a sensor will throw a warning in all of the dependant systems down the line. My advice is to get the codes read as this should at the very least point you in the right direction Let us know how you get on. Regards John

Hi Personally I would not entertain changing the system. (see what I did there!). The electronics on these cars are very interconnected and I would be frightened to death of bricking the car. As others have said a much safer option is to look at using access via aux sockets or even one of those FM tramsmitters you could attach to your phones headphone socket . John

...at least you did only claim to be "notionally capable"! As Eric Morecambe might have put it, The bulbs were all there, but not Necessarily in the right order! 🤣

Don't forget the air filter. If it was a main service the air filter should have been changed at which point something could have been dropped into the air intake. Anything solid could easily damage a turbo... Perhaps require they give you the damaged turbo as condition of repair which would allow you to have it examined for the cause of damage. Good luck John

Hi Don't think any maker will put in writing how long a part is expected to last but that is a very short life in a main dealer serviced car. These guys are from sussex and seem to have good reviews https://www.arunltd.com/ I would still want some more detail from the diagnostic such as the textual explanation for each of the codes and an explanation of what "bit" has failed to need an entire replacement unit. I would also be chasing Jaguar for a contribution at that mileage and age in a main dealer serviced car. Out of interest did they change the air filter?... something dropped down the air inlet perhaps..... I think I must be one of the few satisfied with my warranty (warranty 4 life) from Motorparks which do have several Jaguar dealers in the group. Upto 10 years or 100k it pretty well covers everything and after that still covers big stuff like turbos. Good luck John

Hi Paul Can you name and shame please. That sort of Bullshit attempt to get out of honouring a warranty contract needs airing so others can avoid them! Glad they eventually paid up. John

Hi That mileage is very low for a turbo failure. I assume you have checked MOT history and are happy that mileage and service history are genuine... I would be going to a trusted garage for a diagnostic or even a Jag main dealer who will probably charge around £100 but at least you will be sure it needs doing if you have a second opinion with the same diagnosis. I would have expected a "mechanical failure" of a turbo to be a little more theatrical than a restricted performace light! At least a bit of a bang and some smoke in the exhaust. Please let us know how you get on. Good luck John

My understanding is that a double beep indicates a failed lock test so the car thinks one or more door(s) or boot/tailgate has failed to report a successful lock engagement, not the same as an actual failure to lock 🙂

If you are like me you may find peace of mind in getting a ctek Battery sense: https://www.amazon.co.uk/CTEK-40-149-Vehicle-Battery-Monitor/dp/B0188TGF6W/ref=sr_1_1?dchild=1&keywords=CTEK+Battery+Sense+40-149&qid=1629981144&s=automotive&sr=1-1 At least then you will know when the battery is getting low and can take it for a good run. Bluetooth range on mine is at least 20m through a window with line of sight to the boot of the car. Hope the sensor sorts it. John

Hi Ray and welcome. Is it all doors that unlock with the emergency key or just the door you are using the key in? Will the other doors unlock from inside the car? This sort of issue is often caused by a low battery but may need a garage to sort once it has happened as the software can be corrupted. Some Jag main dealers seem to go straight to "you need to change 2 of the computer modules and that'll be £1000 please". However there are others (Jag dealers included) who will sort it much cheaper. Garages that use the Autologic computer system seem able to sort in minutes for less than £100. Basically they are able to put a new copy of the cars software into the corrupt module from one of the copies stored in the car itself. Let us know how you get on. Regards John

Hi David Pretty sure there is a fault in the offside front ABS sensor or its wiring loom. Not an expert but my understanding is that the The Controller Area Network is how the various computers (modules) talk to each other and the Buses are how the "computer" bit of the module connects to the outside world, in this case the CAN. So those U0001- codes could indicate a fault in the module wiring, or just as likely a poor earth connection or even a low voltage event. Next step for me would be to see if the S/S is now working. If it is, I would get the ABS sensor sorted and have the codes cleared. Hopefully all sorted. If the S/S is still not working and you have a new main battery (hope you have swapped like for like i.e AGM for AGM) then have a look at the secondary one as the S/S only works if both can cope with the stop/restart process. The little one's job is to supply a steady voltage to the sensitive components during an engine restart which is handled by the big battery. If the last time the S/S worked the voltage from the little one dropped that might have caused the U0001 DTCs Finally if you have access to be able to regulalry use a charger I would invest in a Ctek for peace of mind. I also have the Ctek Battery sense bluetooth monitor on mine so I always know what the battery state is. Good luck John
