The tyre pressures are cold temps bare in mind driving to garage to check pressures will increase due to tyre warmth
Sorry if this is taken as read
Puna ST is 32front 26 back
TPMS and App
I usually set mine at 34F & 29R (ST) (cold) to take account of the variations in the OAT (outside air temperature) especially in the event of a sudden and very cold winter's day. That way they are usually within range and not below minimum/max regardless of how many people I have in the car. I find this the best compromise even during the warm weather. That said the sudden warm UK weather today means an adjustment now I think. To my surprise they are currently showing 2-3psi above my usual setting. Always surprised on how much of a difference the OAT can make. But hey I guess we are lucky in some respects we don't offen get heavy snow falls like our friends other parts of Europe. So can get away will sticking with the same tyres all year round in most parts of the UK.
I never rely on just the TPM system I always manually check with a digital pressure gauge.

33 front and 30 back a few weeks back. Now reads this, at least I haven’t got a puncture.

Yeah always go by the filling gauge actualRays1 wrote: ↑Sun May 21, 2023 3:59 pmI usually set mine at 34F & 29R (ST) (cold) to take account of the variations in the OAT (outside air temperature) especially in the event of a sudden and very cold winter's day.

I’ve been topping up through the winter and year to match label and find an average to cover the year seems ok, cold mornings even now are about spot on
I am lucky that at work we have a calibrated compressor tolerance of -0.1 psi so can check regularly when cold tyres
It is more of a hit n miss when using filling stations and working out what has changed through heat transference to compensate
ST Performance Grey Matter (Performance Pack / Drivers Assistance Pack / Dark Wheels & Power Tailgate)
So back to my question - tpms covered under warranty?
Still the O/S rear showing lower than the N/S rear even though I reset via the car and filled to the same psi.
No massive issue I guess.

Puma Frozen White ST Line X 155 Winter Pack & Driver Assistance Pack.
Your best bet is to take your vehicle straight to the Ford dealership. There, they can tell you exactly what’s causing your TPMS issues, what needs to be done to repair them, and whether or not these repairs are covered under warranty.

I see no reason for TPM's not to be covered by the standard warranty.
That said I believe Ford service technicians have a way of receiving the output (signal) of the TPM remotely.
For information the TPM's for the Puma are around £35 + vat each (or was when I last purchased one for my spare wheel. TPM's are simple to fit, they are attached to the valve on the inside of the tyre. TPM's are a sealed unit and not repairable. Easy job, to replace once you get the tyre off the wheel.
TPM's have an integrated battery which will likely last between 4-5years. I guess it is entirely possible for the battery(s) in your vehicle/wheel(s) to be on it's last legs and hence giving you a false reading. As I've said b4 don't rely on em. Use a decent external pressure gauge and not one of those at your local petrol station, they are never that accurate.
