Tyre Pressure Monitor

[Liftsagift]

Hi Guys,
My maca is approaching 2yrs and the tpm occasionally warns of a fos tyre 0.4 low. On checking the individual pressures they are all ok. It's always the same tyre but presumably the sensor is ok as it reads correctly when selected. Has anyone else experienced this or have any ideas?

Thanks,

Try resetting the tyre type and wheel size in the multi-function display - even if they appear to be correct.
The system will re-learn the pressures after driving for a while at over 16mph.
May also be worth checking to see if “full” or “partial” load has been correctly set (again in the M-FD).

My 718 showed up a 4psi drop warning last week but it looked normal to me so I reset it and off I went again. Following day, same thing - all four wheels reading 26 - 28psi but a warning on the ORS wheel. So I decided to actually check the pressures in a real garage. Turns out the pressures should be around 30psi, so silly me for not checking them regularly. Mind you a 4psi drop isn't a hanging offence but it's nice to know that even a small drop will flag up a warning. All correct now.
