TPMS Replace and Relearn experience
My car is a 2011 XKR 175 with 20" Kasuga wheels, 255/35R20 front, 285/30R20 rear.
For almost six months I had been having TPMS "gremlins". The car would be fine, then one, two, or even all four wheels would show low tire pressure. Then the error would go away. Since all four wheels were having trouble, I began to suspect that the TPMS module was bad, but then again the car is over ten years old, so the tire pressure sensor batteries had to be nearing the end of their life.
Noticing that the 2015 tires were looking a bit worn, and had less grip than before, I ordered a set of Michelin Pilot Sport 4S from Tire Rack. I also ordered four VDO SE52081 tire pressure sensors from the least expensive source I could find at around $45 each. I was tempted to try one of the less expensive "universal" brands of TPMS, but ended up going with a reportedly "OEM" model number for not much more money.
My installer installed the tires and the TPMS, and balanced them up, but was unable to get them to register with the car - even after aiming their favorite TPMS tool at all four wheels. Feeling confident in my earlier Google research, I signed off on the install and made it my problem.
My first task was to "drive it around" since that is sometimes supposed to register the new sensors with the car. The drive was highly enjoyable, crossing the Golden Gate and San Francisco Bay bridges, but I had no luck getting the car to see the sensors. Returning home, I hooked up up my ODB tool and found all four modules showing the same tire pressure - 14.5 psi if I remember correctly - which is suspiciously identical and of course impossible on a fully inflated tire. Looking at the old sensors returned to me, they are a Ford Motor Company part number S7HZA, not VDO. My heart sunk.
The next day, I took the car out for a drive, and about 15 minutes into the trip, the tire pressure errors went away, and have not returned. Apparently it just "takes a while". Note that I did not need to do any of the "drop pressure by 3psi' or 'air out, then turn on the ignition then inflate' or any other trick. After 24 hours and two drives it all just sorted itself out. At least so far.

Yes, that's how the system is designed. Nothing is supposed to be programmed by anyone. The car does it by itself.

For everything you need to know about TPMS sensors and modules, see my Post #9 in this thread:

Good luck that it stays working!
Jaguars have horrible TPMS systems. I've replaced all my sensors and the module. Ensured that the connections from antenna paddles are all good and no pinched wires. I STILL get intermittent TPMS warnings.
I think your best bet is to have the entire system disabled by someone with access to SDD. Next time I'm at the shop, it's what I'm doing.
