Rear tyre pressure warning

[RaspberryMan]

Can anyone explain what is going on here. The last couple of journey's have thrown up the 'rear left tyre pressure' warning but as you can see the car is quite happy that all the pressures are normal and equal. I can't even find a way to clear the error to see if it's a transient "one of those things" error.

I'm stumped, any ideas?

The correct tyre pressure is 37psi so why not pump them all up to that?

The threshold may be something like 33.08psi and 3 may be at 33.09 and the other at 33.06 - all 4 will show 33.1 when rounded to 1 decimal place.

As said put a bit more air in all of them and drive it for a half mile or so and they will reset.

How did you get it to show psi?

Good point - would much prefer PSI instead of Bar and never seen or heard of one showing PSI.

Would like to know too. I was under the impression the European ones show PSI, UK ones bar and you can't change it, but the OP is in Scotland

Mine's in kpa, and I can't change it.

The left rear seems to be the one that registers first, then 'multiple tyre' warning follows if they are all low but quite often the yellow warning 'sticks' for a while even if all the tyres are the same. My MG4 usually throws the warning when it has been especially cold.

Put air in, all sorted. It occurred to me after Alb's post that it was probably a rounding/threshold thing, still looks weird though.

I changed it to PSI by swiping right from the home infotainment screen, clicking 'settings' and scrolling down a page, it's under 'tyre pressure units'.

What infotainment version are you running?
