The Maserati system relies on external temperature readings. I would have hoped to avoid that issue....

But when it’s low, it’s low surely? The setting is 2.2 bar when cold. It’s just that it’s colder in winter.

Fair comment, although I did buy the forum recommended battery in June this year (EA1000 Exide Premium Car Battery 017TE) - and whilst there's always a chance of that being a duff battery, I don't think it warrants buying another one just yet.
Well in that case you can almost definitely rule out the battery, hope you get your problems fixed.

Update: TPMS issues appear to have disappeared, no further warnings upon startup and neither when driving. Looks like the calibration button worked.

The TPMS sensors are part of the tyre valve and have a small battery built in to them. They send a signal to a fixed sensor near each wheel all the time so have a finite lifespan. Mine seemed to last about 10 years and then started showing TPMS faults when cold due to internal battery not being strong enough in colder temps. Once warmed up, either by tyre temp or ambient temp they would work fine. Changed a couple with a tyre change and faults went away. Recalibration sometimes worked if ambient temps were high enough but only changing the valves sorted it properly.
It's a lottery which valves are weak and they are a pricey part for what they are but they look like a generic part with a Ferrari logo on them..

There are Co. who will fit replacements at non Maserati prices.

The one in the midlands has been posted on here as a good one.

Might have been said before but couldn't find using search - is there a cheaper/OEM like part for rear early QPV parking sensons?

Like this one?
Yeah but my ones were only about eight quid each. I've never actually got it replaced, it's in car boot, I'll fish it out with part number tomorrow. I'd decided at 8 quid each may as well do the the lot while bumper is off....

Need to get them painted too.....
