I had this happen to me last week. The TPMS system re-set itself while I was driving the following day with a quiet 'bong' over the infotainment system but otherwise no other message.

Similar story with an ESC 'uphill assist, downhill assist, ESC unavailable, reduced braking performance’ warning that came up a few weeks ago. Very annoying but at least the system is capable of re-setting.

Both issues must be wheel sensor related and the only common factor between my error messages was that they both appeared after heavy rain, so maybe it's damp in the system? My local dealer is going to take a look when I take it in for unsticky door seals next month

Today on a short trip up the M5 has to accelerate to get out of trouble and got the high pressure warning for rear right tyre. Which I wouldn’t have expected at 38psi. What tyre pressures are people running?

Late in the day and the dashboard lights up with an amber message "Tyre pressure sensor lost". Checking the displays, you can see that all four are lost, so I guess the sensor receiver is disconnected/toast.

The Grenadier is booked in for diagnostics on the 24th January, (Chandlers are busy and short a technician).

It's this sort of dumb failure that drives my desire for the full workshop manual now. This should not be a big mystery; it's either a wire break or a failed unit, it should not need a trip to the dealer for diagnosis and fixing. You don't get this sort of irritation with a LR110CSW 200Tdi, (just cold, wet feet, deafened, vibrated and a little cramped!)

I'll report back on the fix, when I have one.

Do you have anything plugged into the OBDII port? I had a speedo plugged in there and kept getting this error. I unplugged it and the error has not returned.

I’m running at 36psi. Although on a cold morning at the weekend they were down to 34psi. But came upto 37psi on a long motorway run. Do you have the latest software. I don’t get these warnings anymore since the very latest updates. A further update installed last week to the “head unit “ whatever that may be.

17 inch wheels at 36psi all round. I'm have been happy with this for the past 8000 miles. I would increase this is carrying a heavy load..

Good question. I don’t think so, as last software update was done 4 months ago, but car is going back in for the heating/cooling issue again so I’ll check if it’s done then. I run them at 35psi all round but might up it having seen the screen shot from the manual below.

Mine also gives out the occasional warning for the right rear. Oddly it will show 36psi all round but always trigger on the right rear.
My guess is a software glitch or maybe the sensor in that wheel is producing a spike.
I just reset in the vehicle settings and forget about it.
