I’m wondering if pulling fuse 19 (12v battery source to TCU) under the rear seats and removing the rechargeable battery in the TCU will reset the software to allow SOTA after a fresh reboot? Would need to put the car in service mode first.

I doubt it all you‘d be doing is resetting the TCU, if you can see the status of the car via the remote app then the TCU is communicating with the internet fine.

Yes, Live apps update fine as well as remote app working, WiFi no issue etc. just blocked from SOTA. Seeing the TOPIx details for H439 and H440 the possible fix is to clear SOTA persistency in the TCU (If this is the known fix). Was just thinking outside the box.

I don't know wether anyone else has thought about this, and it's only interesting, not a solution. H439/H440 state that certain cars weren't completing SOTA updates properly (or something like that) so JLR have stopped SOTA working. The fix apparenty needs the TCU updating to a newer FW version to reenable it again. BUT, how did they turn it off in the first place - Over The Air with a TCU update presumably, and strangely that seemed to work properly didn't it !!

 

[Boothbkk]

Yes, you’re right. It mentions the vehicles have been stopped from further updates and require a wired intervention.

Still no update, explains the inordinate length it was in the workshop (with the doors locked). Still stuck on 3.2.1 although it doesn't seem stuck. Before it was just stuck displaying version number and the date I installed it April 2024. Now it checks then says "up to date" installed 10 June 2022 displaying the release notes. Oh and Waze works with voice now over android auto.

Contacted Jaguar who said it's faulty as they cannot connect to it and to contact the dealer. Dealer's workshop controller advised that "it likely will not display the update until the next update on the vehicle is due".

Reading some of the SOTA updates on the forum it does seem that the updates get pushed about every week to the car until it is eventually caught up to the latest version.
Your issue is unique though, I must admit. Fingers crossed for you.

It's particularly frustrating as I am assured that version 4.0.0 fulfills the H441 recall.

There must be a way of working out what version you're on based on the actual functionality. You've already said about Waze, so maybe something else gives some more clues. I have read somewhere else that everything will need the next actual update from JLR to get installed correctly ! just wait and see I guess. Meanwhile, mine is in tomorrow morning, so since they'll supposedly be following the same technical path as what your guys did - but without the TA maybe - I'll report back what happens to mine, and whether I can convince them to argue with JLR that I shouldn't have to pay for something they turned off !!

I know which version it's on..... 3.2.1

Sorry, I was under the impression that yours had been updated, but that the text showing on the "software updates" screen wasn't showing the correct version - so I was suggesting check things like google/apple maps showing in the dash indicates at least 4.0.0 - things like that.

 

[mwbirchall]

Sorry I didn't mean to come across harsh. I was in a rush as always I fully appreciate any support even if it is only moral

 

[mwbirchall]

What I really fail to understand is that this cost just shy of £500, with no end result? The car still says 3.2.1 it went in to have it updated to at least 4.0.0. How can they charge for nothing? It was in a week (most of which I assume was them praying it would update). In the end they needed their loaner back as far as I can see!

I saw these posts but in the topix

Yip see #169 and #180

I commented on it #144 Makes no sense

4.2.0 got installed tonight, fixed my lane assist which stopped working a few days ago.

Show off

It is puzzling why there is such a disparity in software delivery between older and newer cars, even when dealing with relatively small numbers.

 

[jeffreycooper1963]

I'm fully expecting my £180 tomorrow to be wasted, unfortunately. Obviously any cars that weren't "infected" with whatever SOTA update turned the SOTA facility off, are going to get the latest updates. The only real question, and I sort of hinted at it earlier - I still can;t get my head around how JLR can use SOTA to turn off SOTA on cars that wouldn't update properly. It just makes no sense. What does make sense is that some SOTA update f'd up some modules, and they are in need of "wired intervention" to get them to work again. Now that makes perfect sense, and is absolutely something a company the size of JLR would cover up rather than put right.

Lets see what tomorrow brings - if the technician actually keeps me in the loop like promised, I shall be taking mental notes, and I'll relay them - I may even see if I can get them to show me proof of module update numbers.
