TPMS-Tire Pressure Monitoring Sensors

What module under the seat? The actual "TPMS MODULE" is behind the rear seat. In a convertible, it is also behind the Roll Over Protection hoops.
Maybe the TPMS Receiver is under that seat??? I'd hope so, as that's the lost possible thing to fix MY TPMS faults. I really don't want to remove the whole debacle behind the seats again.

OK, so I checked the air pressure and it was way high. Like 45 psi. Stupid tire shop. So I dropped the pressure to what it was supposed to be. Drove around for a while. Still got the intermittent "Check all Tyre Pressures" warning. So I let all the tire pressures down to <15 psi and filled them back up. Still get the intermittent "Check all Tyre Pressures" warning.
I got the sensors off the internet, and they are 350 Hz. I no longer get the individual tire low pressure warning.
Still wondering what to do. Would disconnecting the battery and touching the leads together help?

I think you mean the frequency is 315 mhz.
On my 07 XK, I had a slow leak in one tire.
The independent tire shop I visited showed me that the leak was around the securing nut, not the shrader valve.
He would not touch it, fearing it would break. He recommended I go directly to a Jaguar dealer, saying that I could use only Jaguar sensors.
There is a lot of discussion about which sensors work and which do not. I do not know the answer to that.
In any case, I went to the Jaquar dealer who replaced the sensor for $170 plus $100 labor.
Happy but not happy,

Sort of an update on my particular situation;
I changed out all the components over winter, and I still had the TPMS fault on the dash.
Now that I've been driving a lot more, I noticed that the FAULT went away, and only sometimes do I get the flashing Tire Symbol on the dash.
PROGRESS!
Since all new wheel sensors, guess I'll try the Over-Inflate trick.
At least I'm getting closer!

Regarding Jaguar only TPMS... I had a screw removed from a tire, and the shop broke the TPMS while trying to inflate it. They installed a rubber-stemmed aftermarket TPMS, which was what they had on hand. The car displayed an alarm after that, but I wasn't concerned because I was taking it to the dealership for another issue the following day anyway. The dealer claimed that the TPMS generally needed to be Jaguar branded. I informed him that the original one was labelled 'Ford'. They checked it out and said that the tire shop had set it to the wrong frequency, and everything was now fine. Moral of the story: They do not need to be Jaguar-branded TPMS, at least not on an 07 XKR.

A shop cannot "set" a frequency. The sensors are either 'Right' or 'Wrong'. There would be ZERO reason for a shop in Wyoming, USA to have a European TPMS sensor with 433 MHz when the US uses 315 MHz exclusively. The dealer is lying to you about two things at least.
Your car doesn't need anything SET. It will learn the TPMS sensors while driving within 60 miles.
Besides, the "CORRECT" TPMS sensors are Siemens brand.

My trust level in dealerships is low, always has been. The issue did go away after they looked at it, and they did not charge me for that. I can't tell you exactly what they did. My assumption is that they try to scare you into buying branded parts, and also try to dissuade you from using indy shops. I thought that the alarm should go away on its own after putting a few miles on it, as the manual states, which it didn't. Those woes aside, my TPMS does not need to have Jaguar stamped on it.

My understanding is that the in tire sensors are manufactured to be able to transmit either 315 or 433 mhz.
The programming sets the frequency to use.
If purchased from Jaguar, it will be already programmed.
If purchased elsewhere, who knows.
These things need to be programmed before use, then after that, the car relearns what ever it needs during a short 20 mile drive.

No tire shop will stock the more expensive and useless dual-mode sensors, and certainly not stock the ones used in a different country.
