You're talking yourself in circles here Pete... :)

[SNIP]...
Might be writing in circles Steve.. but the thought was linear, honest.. :D

Thinking out loud: if the motor/solenoid that operates the dead lock has failed, could this explain CVB's situation?..

As for operating the lock from inside, this is the internal cable going to the operating lever on the mech:
Auto part Automotive exterior Bumper Steering part Vehicle


When in place it is right up against the inner 'wall/skin' of the door as you can work out from this:
Vehicle door Vehicle Auto part Wheel Automotive wheel system


Proper difficult to get too.

The white right angled part in the first pic is what operates/releases the 'lock' part of the mech.. apparently they are prone to breaking causing the door not to lock, I wonder what happens if they break in the 'locked' position.. could that perhaps be CVB's issue?

Not much help as a post I know.. but it might prompt someone to come up with something useful?....

------------

As for a Jaguar independent CVB, the only one I'm aware of is G & D motors in Falmouth: https://en-gb.facebook.com/pages/category/Automotive-Repair-Shop/GD-Motors-533085630038327/

They are at the old Ryders Jaguar workshop underneath the wine warehouse that used to be the showroom.

Other than that it's means crossing the border... o_O

Thanks for the information but Falmouth is 65 miles from me so I've sent a message to a Jag specialist across the water in Devon to check whether he has the Jaguar software on his computer so that I can get an accurate diagnosis before I start doing any damage or spending real money.

I've still got to figure out how to open the door.

The problem of opening the rear locked door has been solved.

I was watching a youtube video of a couple of lads tackle a Land Rover Discovery with dodgy rear locks. They were experimenting with the mechanical lock mechanism attached to the interior door handle. I've never used this part of the lock and did not think to experiment whether it would help solve the problem of opening the door.

Me and a clever bloke from down the road who works as an engineer in the dockyard played about the the single and double locking and the use of the interior locking lever. Lo and behold, the door unlocked when the locking lever was pulled out and the handle actuated. There is still an internal problem somewhere in the latching mechanism caused when the car is double locked but at least I can open the door now. I can get two new mechanisms (left and right) from Ebay (item no 153828657601) for £32.60 (direct from ChengDu City via Lichfield) and fit one myself - now where did I put that set of Torx screwdrivers?

Well done on getting it open. Could have been rather messy.

Good luck on the eBay lock mechanisms too. Many have tried the bay of E for lock mechanisms, only to resort to the dealerships as they simply could not get the correct units.

I am pleased that the door can be opened but a little disappointed that I did not think to experiment with the interior locking mechanism before yesterday evening.

Mind you, I spoke to five garages including a Jaguar specialist (not main agent) and none of them mentioned trying to unlock the door using the interior door lock.

Still, all's well that ends well, as they say.

Gad you got it sorted without major surgery, I think one lesson here is to investigate faults sooner, and yes I too am guilty of leaving stuff until it becomes a major headache...

Thinking about this.. I thought the 'ordinary' door pull handle would unlock a locked door from the inside as you pulled it?

I imagine it was a tough call to risk closing it again, after getting it open :)
A moment of trepidation if ever there was one.. :)

That's exactly what a "dead" locking feature is for. Even if the window is smashed it will prevent the door from being opened through the window.

Pretty sure it's a requirement for the thatcham cat 1 spec.

Hence why I carefully said 'locked' Phil.. and if you are correct about not being able to open a deadlocked door from the inside.. it doesn't explain how CVB has opened his from the inside now.

Reasons:
If the door was deadlocked he shouldn't have been able to unlock the door from the inside from the info you have given..

If the door wasn't deadlocked it should have unlocked and then opened by merely pulling on the 'open' part of the internal handle, as the open and unlock operations are done by a single cabled two part operation.. at least they are on a 'passive' lock assembly...


Maybe that's where my differing experience is throwing a spanner in my logic?..

So here's a tabular summary of what worked and what didn't :-

After Single Lock Unlock​
After Double Lock Unlock​
Lever Interior
Yes​
No​
Lever + Lock Lever
Yes​
Yes​
Door handle Exterior
No​
No​

I hope this helps somebody.

I suspect that my issue started after a double lock and stayed locked until I managed to open it yesterday while I was trying different options. Then the interior lever started working again. Because the door cannot be opened from the outside, it's an MoT failure until it's repaired.

Does anybody know why there are many OEM part numbers for the latching/locking mechanism?

This is a photograph taken from INSIDE the left rear door showing Jaguar's label on the door lock. None of these numbers tie up with OEM numbers of locks advertised in the internet. Anybody know why? DL RR LH probably means Door Lock Rear Left Hand and 090712 appears to be a date but what's all the rest about and which part is the OEM number?

Can anybody offer any information about the various OEM numbers for the left rear lock. There is a Jaguar part number - C2Z31364 - and several OEM numbers quoted on the internet - FQM500390 is one - and 8X23-24995 is what's on my lock. In addition, it appears likely that the same mechanism is used on some of the Land Rovers and Range Rovers but with a different LR part number. I've only seen my part number quoted by breakers yards for second hand parts that are 10 years old. Who wants to buy a ten year old lock when my own eight year old lock has failed?

Does anybody know if the parts made by different OEMs are interchangeable? The basic lock mechanism may be the same but the outside door handle mechanism has to connect to this thing and if each manufacturer is slightly different, the lock actuator may not fit with the existing door handle connection. What I need is a parts list with all the various identical OEM parts set beside the Jaguar part number. Does such a thing exist?

The genuine Jaguar part is about £130 and aftermarket parts are about £25 so if an aftermarket part can be made to fit, there's a considerable saving to be had.

If I were you, I'd throw my trust (and £25) at an after-market one in the first instance. I doubt very much that the fittings will differ from the OEM one as the easiest thing to copy are the case mouldings and once those are right everything else will be in the correct position.
I have had to replace two door latches (one on my XF, one on my S-Type) and both were after-market and both fitted perfectly. (There was a problem with the XF one but that related to the keyless / non-keyless issue where the seller didn't know the difference between them!)
