Firstly I believe the Stellantis Mokka monitors tyre pressure by monitoring differences in the rotational speed of each wheel. There are not pressure sensors on each tyre.
My experience with this type of system is with a VAG car. It will tell me which tyre has the problem, unless the whole system does, but that is another story!
I have checked the Vauxhall Mokka manual and it does not say whether the system will actually tell you which tyre it is, does anyone know if it should? Has anybody seen it? If it should, but doesn't, that would imply to me that it is a system fault.
The manual also says you should initialise the monitoring system if you change a wheel, tyre, or even pressure. This again would imply the system itself does not care about the actual pressure of the tyre, just its 'new' rolling circumference. Changing a tyre by 1 PSI should not make a difference to the system. I would suggest the system is either not initialising correctly, or the whole system is receiving corrupt data from a 'dodgy' sensor, or most likely the software has a glitch. All of which are a Vauxhall under warranty problem.
