I had a problem with my TPMS (2010 XFR). It started throwing warnings randomly while tyre pressure was OK.
I finally tracked it down to a dodgy Ebay USB charger plugged into the cigarette lighter in the center console.
I Unplugged it and the warnings went away after 10 mins and didn't return. I plugged it back in again and the warnings reappeared within minutes.
I tried plugging it in and disconnecting repeatedly and there is no doubt that this was causing the issue.
The USB charger is in my wife's car now where it doesn't cause any problems.
Thanks for posting this.....
I too, have a USB charger in my '08 XK-R and have received the same sporadic warnings, with no truth to low tires. I'll check this aspect.
Had started to get the TPM signal in my car. Checked all the tires, pressure spot on in all tires. Indy said one was bad, remember this is a 2013. Just to save having to take it back in when the next one went out, we just changed all 4. Now its time to go for a long drive to get the system re-set.

The new TPMS should sync to the Jaguars system within 5 minutes or less after installation of the new TPMS.
I just came across another problem with the TPS fault I have an IPhone 8 that i have charging on the center console with the wire running along the console over the TPS sensor being non shielded cable it was interfering with the sensor causing a fault I had replaced all the wheel sensors as well as 2 antenna and the module by the fuse panel in the rear and still had intermittent faults showing I have moved the phone to the passenger seat on 2 separate occasions when the fault showed up and within minutes of removing the phone the warning would go off since trying this several more times I'm now certain that was the cause because for the last 2 weeks i haven't had the fault show up . Hope this helps someone
Your post is of great interest as I have an '07 XK convertible where we added an iPod ACM module.
The service shop who updated the IDS software and activated the module was great - although when they turned the car back over to me the tech said "oh - your TPMS just came on"
We've had the car for about 5 months and have NEVER had any issue- - so I was of course curious why this would activate immediately after their IDS work.
I installed the ACM myself and did run the Ipod cord along the console (per instructions).
Anyone else have this issue?
I'm guesssing that if I open it back up and provide some better insulation around the cable that this will solve the issue?

Before going to all that trouble, get the batteries in the TPMS senders in the wheels checked out. A tire shop, maybe even an auto parts retailer that reads OBD codes for free, has a TPMS reader, and can check to see what your TPMS battery status is.
If those are original units, its very very likely that one or more batteries have died by now.
Thanks - I'll do that.
It just seems so odd that within minutes of activating the ACM this has popped up - - where it has never (ever) been an issue for me since geting the car ~5 months ago.
What can happen during any programming is the battery gets too low because some techs don't connect an adequate power supply during the programming, and since these beasts are buggers with low voltage it MAY just need a good charge on the battery. Like, an overnight session with a 10+ amp charger.
The instant I got my car back after a new key programming at the dealer I had Dynamic System Fault, E-Diff Unavailable, and another one I can't remember. After a 45 minute drive on the interstate and a restart, everything was back to copacetic.
the wire running along the console over the TPS sensor
OK, this is interesting. You're saying there is a sensor in the console? Where exactly? I have my iPhone cable running under the center console, around the gear selector, and coming out in the ash tray. I can't imagine it's related, but still I'm curious where this TPMS module is located that you are referring to.
I've run into problems with my non-shielded radar detector power cable setting off my detector, such that I had to wrap the cable in tinfoil to get it to stop, so your idea is not beyond the realm of possibility...
The TPMS receiver & module are by the Auxiliary Junction Box between the rear seats (receiver behind LH rear seat, module attached to AJB bracket). There may be TPMS wiring under the centre console, but there's no TPMS hardware under there. This applies to both 4.2 and 5.0 cars.

Correct. It's part of the main wiring loom and runs from the module, under the console and comes out and the CJB under the drivers side A pillar. Then it goes out to the antenna in front.
Thanks Guys for that info.
Given the near-immediate correlation of the issue cropping up and some of the related experiences / comments about chargers causing issues, I think I'll start by just popping the console cover again and wrapping the (new) iphone cable with some copper tape.
I bought my 2010 XKR in May of 2023 with around 25.5k miles. Soon after I began getting the car icon with the arrow "rotating" around pointing to each tire at a time. I assumed the TPMS sensors were original and bad so in 2024 I had the tires replaced along with 4 new TPMS sensors by Bosch (QF0470) purchased on Amazon.com. I also have an ICarsoft LR v 3.0 DTC. Based on readings, I am getting CODE: C1A57-13, STATE: Intermittent, DESCRIPTION: Front Left Initiator.
Yesterday, I replaced the initiator (tennis racket antenna), on the Front Left and installed the "old Front Left" into the Front Right. Still getting the same error, and both front original initiators and the new initiator read around 1.8 Ohms and when using a voltmeter I get a closed loop beep.
I also pulled Fuse 2 from the Junction Box behind the rear seat center part. In fact, I checked all fuses and even the large 3 bars by the battery. I unplugged the receiver but didn't look for the module as I was under the impression that was under the right/passenger front seat or at least that seat needed to be removed to get to it.
Using the Icarsoft DTC, under TPM I have "Tire Pressure Monitor System--Replacement where all Bosch sensors are registered. "Tire Pressure Monitoring Confirmation Application" which works fine, "Tire Pressure Monitor System--Receiver Calibration which also completes fine, then I get to "Tire Pressure Monitor System--Sensor Identification Display gives me a Communications Failure.
I haven't removed the bumper cover but have removed both headlights and tracked potential pinch points on the wires, removed the electric tape and re-taped each wire individually than the set together.
After reading this Sub-forum it appears a few of you had success after replacing the TPMS sensors with VDO/Siemens which are the original sensors. Before spending another $300 on this potential fix, I was wondering if anyone has/had the same issue and found replacing the receiver and/or module brought you any success.
Any tips/suggestions are much appreciated.
CAR: 2010 XKR Convertible
Mileage: Currently 34K Dashboard issue Error from DTC Battery Reading when start is ON but engine is not running. Tire Transmitter ID Wheel Unit--Unclear what it is Bosch Sensors installed and programmed into ECU IcarSoft screen for TPM and 4th option that gives me communications failure

I've been chasing this on and off for the past month and a half as well. Issue started just before I replaced the wheels (so know it's not the wheel sensors themselves) and it comes and goes by itself; with an occasional kicker of "Tire not monitored" for the Driver's front wheel. It started around when I pulled the front bumper off to realign it, so on Saturday I pulled it again to check the wires and they were being pinched by the bumper support on both sides; but I haven't driven it enough since to know if it will go away (and do so for good) now that I taped them up out of the way. I also replaced the battery the weekend prior after an "Adaptive Dynamics Fault" scared me into actually checking the battery (which was from 2018, it turns out), but the TPMS fault has come and gone and come back since then even after the scary expensive suspension error went away following the battery change.

Ok, so you may have already fixed the problem (after possibly creating it yourself). Time will tell.
As an update, I drove it for about a week before I took it to a specialist to have my oil changed and Spires springs/F-Type steering rack installed, and the problem didn't seem to go away in that meantime. Since I was already setting money on fire with the work I was having done I requested for them to check for any other stuff that needed tending to when they had it disassembled, and they found that one of the front hubs was failing (among some other worn suspension parts). Having had them replace it, now the TPMS Fault itself has gone away completely (though I still have one allegedly new tire sensor that keeps saying it's not monitored that I have to replace). Maybe it's coincidence that changing the hub fixed it, but I'm pretty sure the fault had gone away and come back since I dropped the bumper and tended to the wiring, and it definitely doesn't now.
