On mine the work was tried at the purchasing dealer (Fiat/Volvo) so clearly they did not have SDD. The fault came up as Front Outer Parking Sensor which they changed but did not cure the problem so sent me to Jag dealer. My understanding is that the Jag Dealer found the same fault code and, as the sensor was already replaced, had a play with the front bumper loom to arrive at their diagnosis.

Hi. That happened to me too, several times before it finally went altogehter. See what the codes are as it is quite possible it is a dodgy parking sensor or a dodgy connector / bumper loom. Good luck

Hi Camera and parking sensors work as a a coherent parking assistance system so a fault in any component will automatically shut off the other bits of assistance and warn you that you are "on your own". Need to get the codes read with a jaguar compliant code reader but if you have already done the boot loom my bet would be a front parking sensor or the front bumper wiring loom. Mine was the wiring loom. @£40 for the parts from Jaguar. Other possibility would be low battery which throws up all sorts of random faults. Does you Stop/Start work? Good luck

Hi From fig 58 it looks like the front axle differential is built into the gearbox casing, Info from www.jagrepair.com Regards John 2002 MY X-TYPE Transfer box.pdf

Hi The XF is very unforgiving of low voltage and it can cause corruption of the many computers which would cost a lot more to fix than a battery replacement. If I were you I would change the battery now or get a CTek charger to keep the battery topped-up until you do change it. Failing that, at least make sure you do a good hours drive when you do use it. John

On my 2013 XF sportbrake the problem was faulty front bumper wiring loom (front offside parking sensor connection corroded) replaced for less than £200 by Jaguar dealer. On the XF the parking sensors and camera work as a complete system so a fault in any part can shut down all of it, eg a faulty front parking sensor can stop the rear camera working as well as the parking warnings. If it was me I would be trying a good auto-electrician as they should be able to repair the wiring loom or even replace it with a used one for a fraction of that price. I would only expect that sort of cost for replacement of the entire wiring for the car. I know it is apples and oranges but I had the entire front wiring loom replaced on a Peugeot 208 by main dealer for £1200 4 years ago. Good luck

Hi As I said in earlier post mine had this sorted before I got it but it came with a receipt from Preston Jag Centre for @£1100 from late 2017. I have heard good reports about JagMan in wigan. Might be worth a call. Hope you get it sorted OK.

Hi I get @25mpg in town, @35mpg on short journeys to the shops etc, @42mpg on a run and 50+ on a motorway run. Highest I have managed is 62mpg at a steady 55mph on a quiet, flat motorway. Love the car in all of the above scenarios. Your actual figures would depend on how far you are from the motorway at each end, what the traffic on the motorway is like etc, but mid 40's is easily achievable on that sort of journey. 🙂

Hi Bruno Can you give us some more detail. Any warning lights or messages? Does it turn over? Does it Lock/Unlock OK? John

Have you tried an adapter? Would this work? https://www.ebay.co.uk/itm/144342187254?hash=item219b76fcf6:g:5L4AAOSwa21hxEyW

Hi Mark I have 2013 Sportbrake. On mine a single press of the lock on the remote locks the car. A second press engages the deadlocks and will be confirmed by a single beep. I think the "logic" is the same in the keyless system. That is the single beep means the computers have recieved confirmation from each of the door and tailgate locks that the "lock" action was successful. If they don't get that confirmation you are given a double beep instead. That suggests you are locking the car. Is it every lock you can still open after this or just the drivers door? I would try locking at the limit of the remotes range (walk away trying to lock until you reach a range where it won't lock then add a couple of yards with the key pressed to your head). Once you get a single beep take the key even further away before trying to return to the car (obviously without the key) then check each entry point. Only thing I can think of is a mechanical failure in one mechanism which engages the lock mechanism sufficiently to allow a successful lock to be mis-reported. If all entry points are unlocked but the car still only gives a single beep I am at a loss..... John

Hi Basically the camera and parking sensors work as a system and if one bit fails they all down tools, the thought process being it is better to tell you that you are doing things without their help than let you bump into something because one bit was not working and you were relying on a warning that never came 🙂 You need to get the codes read which should identify the problem area. In my case it showed a faulty front parking sensor but it was in fact the front bumper wiring loom feeding that sensor (identified when changing sensor did not fix problem). Good luck

Other area to check for water is drivers footwell. Other than that I think I would try an auto-electrician or Jag specialist. Do you have a Ctek charger? If so I would keep that hooked up until you get the drain sorted as the computers can react badly to very low voltages. Please do report back when you get it sorted. John

You pays your money etc.... The real advantage of All Season tyres is that you give up 10% of your ultimate, on the limit summer performance for a 30 or 40% improvement in grip when temperature falls below 8C. It all depens on your priorities 🙂 John

Big fan of All season Tyres for British Climate and as a driver who doesn't drive it as if I stole it 🙂 My 2013 Sportbrake is shod with Bridgestone A005 Evo Weather Control (245/40 19). Still not had chance to try in serious snow but grip in wet or dry when below 8C is significantly better than any summer tyre and in summer is still A rated in the wet. I also still have 4 Jaguar snow socks in the boot (still in original packing) as a couple of years ago when I still had a SAAB 95 (shod with Michelin Cross Climates) I nearly wet myself watching a BMW and Merc failing to get up the slightest of inclines in just a couple of inches of snow and vowed that would never be me!

Hi I think you have probably answered your own question. If the Diff casing is oily you have a prime candidate to investigate as it should not have any oil on it 😞 The atached might hep you to diagnose (pg499 on) but I think you probably need new seals and a top-up as a minimum. Regards John 650456070_2010XFRWorkshopManual.pdf

Hi Terence You really need to read the fault codes (or get them read) as that should locate the fault. All modern cars use a host of sensors to monitor various functions and many of the functions are inter-connected. So a possible fault, such as a faulty ABS wheel sensor, which is designed to measure wheel rotation, primarily to allow the ABS to function when needed may result in an ABS fault. However the information from that sensor is also used to allow other systems to function, such as traction control which is managed by the transmission "computer". If a sensor does not "answer" correctly when asked by its contolling computer for data, a fault is logged and the driver warned that functions may not be avaialble. In addition the car may switch them off to ensure they don't fail at a safety critical moment. For example a fault in the front parking sensor wiring disabled ALL of my parking assistance and reversing camera as well as telling me that I was "flying solo" and to take extra care as none of the cars assitance would be available until it was fixed! Hope that helps. John

For me the starting point here would be to check the actual level of oil. If you have been topping up because of a low oil level warning (was it low oil level or low oil pressure?) but the AA say there is too much oil in the engine, top of the suspect list would be the oil level sensor mis-reporting the level. Just to be clear though, did the AA say there was a lot of oil in the engine OR a lot of oil in the engine bay? The first indicating the engine is using or burning oil. The latter indicates an external leak. If the engine bay is full of oil then engine oil level may well have got very low possibly allowing the engine to run without sufficient oil damaging the bearings / bores / pistons but I think those things are only really apparent after at least a partial strip-down not after changing a turbo and EGR. Other than totally destroyed bearings / pistons / rings etc the only reason I can see for a new block is that the old one is cracked; and that should produce very clear symptoms. Depending where the crack is you would expect at least one of the following: Oil burning in the cylinder - Blue smoke in exhaust Oil in Coolant - Mayonaise visible in coolant resevoir Coolant in oil - Mayonaise look to oil (visble in filler) Coolant in the cylinder - White exhaust (steam). Minimum diagnostic, I would want, would be a compression test of each cylinder to verify location of a crack. When the engine does run is there any visible smoke? Regards John

Hi Jon I presume you have checked that you do not have a swimming pool in the spare wheel well. My Sportbrake had that before I bought it. I does cause these sorts of problems. John

Hi Jon Have the current problems appeared since the battery change? It sounds to me like some of the modules have had their software corrupted. It might be worth looking on here for a thread about a company which I think was called EE in the midlands who use the Autologic diagnostic software. They seem able to reocde modules with much greater success (and cheaper) than JLR main dealers! Can't hurt to give them a call. John

Hi Neil I would say not. It is not a part of a normal service and the previous owner was looking to sell on (to you?) so although the dealer probably asked the owner.... If it is a main dealer history you can look it up online or ask the dealer concerned who should be able to help. John

Hi Tom Sorry if I am being thick but why is it not covered under the Jaguar warranty at that age? John

Hi Richard Depends on the state of the car when you are measuring it. If you have unlocked the car and opened the boot to read it: Yes. As soon as you unlock it the car "wakes-up" and turns on all of the computers which use a lot of Amps. If you are reading it through a window with the car "asleep" then you probably have something which is suffering insomnia and failing to go to sleep when it should 🙂 John

Whilst that is probably fine, personally I also use a controller to fit between the solar panel and the car. The panel, if connected directly can reach 18v output. With a controller that is capped. I use one of these: https://www.ebay.co.uk/itm/143963161628?hash=item2184df841c:g:heMAAOSwkG1gO1QY and when the voltage reaches 13.5v it stops charging the battery. I only use this set-up for airports etc as normally keep the battery topped-up with a CTek when on the drive.

Hi Bob Front bumper off, but not as daunting as it sounds 🙂 ...and yes, Black is Best 🙂 John
