No positive results. I have inflated all tyres to 39psi, there has been no change in the behaviour of the TPMS warning. A member on here with whom I have been in touch via another platform has offered to de-activate the TPMS which I think is the path I will take, the large warning is a right pain in the neck and only ceases to operate on a long drive so for any local commuting it is a constant annoyance. Perhaps next time I am up for new tyres I will consider renewing all the sensors and the central module but I don't want to start down the path of throwing components at it at present.
You don't need to throw money at it. The average life span, or rather expected life span of a sensor is 7 years. I might have missed it in your posts but it's the first place to check, Here in the States, any tire shop will check the TPMS for free or a nominal fee. It takes about 5 minutes to check and confirm that all sensors are sending a signal as well as spare if your vehicle has one in the spare.
If you're not dependent on them and regularly check your air pressure, disabling it is the option. Again, here in the US, it's illegal to disable the system but don't think that's an issue for most other countries.
I had all these same issues and took it to the dealer where they updated the software in the tpm module and recalibrated the tire size and all was fixed for me !

Now that is an interesting thing. Is this something that an independent Jaguar specialist should be able to do, or only a dealer? I need to establish a relationship with a repairer and I think it will be an indy rather than a dealer.

I think some Indy specialist should be able to do this as long as they have a system like Autologic that can program modules on this particular car,if not then the dealer is your only option !
I have the car booked in next week to have the TPMS de-activated. I think when I next am in the market for new tyres, I will re-visit the system with a view to changing the wheel sensors, but for now I will be happy just to get rid of the warning from the instrument panel. I have never had TPMS on any other car and have never felt the lack of it, except perhaps on my Land Rover when doing remote outback travel. I bought a digital pressure gauge that will live in the car so I can keep an eye on the pressures.
Are you going to an indy to do this or dealer ? If dealer ask them if they can update your tire pressure module with latest firmware then calibrate the tpms sensors should fix it !
It's being done by an independent specialist, I'm not going to spend time faffing around with it at present, just getting rid of the annoying warning prior to a road trip end of next week. I'm happy to leave it disabled at present and look into replacing sensors and updating software next time tyres are renewed.
An update on this one also; the TPMS has been de-activated and I am enjoying blissful motoring without any annoying warnings flashing in my face. I still think I will re-activate the system with new sensors when the car next gets a set of tyres, as I prefer to know that everything is working that should be working; but hopefully that will not be for a little while yet, as I bought the car with a new set of tyres as part of the deal only a couple of months ago.
After I fitted the new Module, the system worked perfectly. A few weeks later I drove 650 miles from France to Cheshire in the UK, no problems.
The following day, when I started the car, I had a check pressure warning. My first thought was not again!!!
A quick look at all 4 wheels revealed that I had not 1 but 2 flat tyres. It turned out that both had nails in them, fortunately, in the tread so they could be plugged.
Just goes to show that when the system works correctly it's a god send.
I must admit that I was happy it happened at the end of my journey and not half way.
Just to add. I too was contemplating having the TPMS disabled. Really glad I didn't now.
Yes I would really rather have it than not, but malfunctioning is the same as not functioning and I have been driving without TPMS for 40 years so I will do my best to manage without it for now. I'll replace all the sensors when next the car gets tyres changed and that will be at least a known starting point.
Just read through this thread. Here's my four-penny-worth:
From what I've read, almost certainly one or more of the TPMS valves need replacing.
Make sure you purchase the correct valves for your MY car. (One of the numerous numbers on the valve will have "AE" as a suffix for your car. See photo.)
ALL Jaguar TPMS systems self-learn and will pick up a new valve (if it's the correct one). Don't let a tyre fitter try and tell you that they need to a) activate the valve, or b) program it to the car. Neither is needed!
