I had the timing chains/tensioners/guides replaced and new Lifetime Bilstein Shock Absorbers installed.

Hi Alistair My understanding is that a replacement module will need coding to work. I would do a ring around and see if you can get the problem solved without a hardware change. Most likely problem IMHO is the software in the relevant computer module was corrupted by a transient low / high voltage event in the battery change (unlucky but it can happen). The simplest fix is to restore the software which is almost certainly possible with the correct diagnostics software and knowledge. Good luck 🙂 John

Cheers John, Thank you for your rapid response. I’ll know my next port of call if the BCM module does not work. Alastair.

Hi Alistair I Feel your pain having suffered permenantly locked rear doors / non-operational rear windows when I let the battery of my 2013 Sportbrake go flat in the first Covid Lockdown. Mine was fixed under warranty from a Non-Jaguar main dealer, (after the AA managed to get in and jump start it) who did have access to Jag main dealers in the same group. They apparently talked them through the process of re-coding the module using their generic "Autologic" diagnostic software. If you search on here there have been a number of threads about garages who can sort this in 15 minutes for around £100. I think one was a company called MDM at Coalville Leicestershire Obviously the East Midlands is a long drive from Cornwall but might be worth it. I think my first port of call would be to ring around and try and find a more local jag independent (there is one in Honiton, Devon) and see if they can sort it. Pretty sure the BCM replacement would need coding to the car in any case. Good Luck and please let us know how you get on as it helps others in the future. John

Hello all, I have owned a 2013 Jaguar XF for the past 11 years. Recently, at a non Jaguar garage, the alternator was changed, requiring batteries disconnect. I suspect that a battery saver was not used. Consequently the, dreaded, central locking failure and inability to set alarm was an immediate problem. I have subsequently replaced the batteries with, a scanner, battery reset done by the same garage. They, however, are unable to repair the central locking problem and don’t seem to be particularly interested. An electronics specialist believes that the rear body control module was “blown” when the batteries were disconnected at time of the alternator replacement. I have ordered one on eBay, just in case. Does anyone know of any other solutions, should replacement of the BCM prove unhelpful. Regards Alastair Paterson.

Thank you, I’ll check this evening

The dashcam I have (not fitted) has an inline fuse already. I think that it is better to have a 2 Amp inline fuse just for the cam. Be careful if the wiring can chafe anywhere on the body work. Without going to a circuit diagram check if you have any contacts permanently live in the 2 dash panels.

Hello I have a hardwire kit to install a dash cam on my 2005 S Type. Does anyone know which fuse I could use that has a permanent supply? thanks Julian

Hi Phil Info to help replace the stalk is here: http://www.jagrepair.com/JaguarXFLightStalkReplacement.htm Lots of other useful info on that site. Sounds like it might be a dodgy contact in the stalk or a faulty Central Junction Box which controls current flow to both the indicators and the headlights. Does indicating turn main beams on even when light switch is off, or does it just move from dipped beam to full beam when the headlights are on and you try turning? John

Hi ste-- A big welcome to the club be nice to see a photo of your 1994 XJs all the best --- Frank

As the most untechnical person on this planet, I wouldn't know where to start 😏

1994 xj40s i have owned the car for 3 years and i have a stalling problem.The car starts first time but soon as it gets to normal temperature it goes into a stalll if i keep the engine going by revving the engine manager light comes on and drives perfect . I have changed the temperature switch and lamba sensor exhaust and egr valve and also get fail 44. i have had the garage look at it but still can not find the fault any help would be very much appreciated Thanks ste

Try exposing the stalk operating elements and clean up the contacts with contact cleaner. N6 JMX

Isn't it slightly illegal to have this type of fault?

Have a look here Andy; https://reluctorrings.com

Hi Phil, I have the same happening on my 2006 XK except for the fact it happens when i turn left!, started soon after I aquired the car 2 1/2 years ago now. My specialist told me it's the stalk that needs replacing however your post just reminded me that i never got around to doing anything about it. So replace it or forget about it and save some dosh and enjoy your car.

Hi, needing to find an O/S/R abs ring for 2007 Xk (reluctor ring) so far struggling to find anything other than a full drive shaft and as I understand it there are two different sizes? Hoping someone can point me in the right direction. thank you andy
