My 2018 has the optional 21'' alloys with the ''standard'' black rubber tyre valves. Quick question but is there a T.P.M.S on mine?. I'v been into the car system on the MMI & can find how to check the oil level etc, service info etc but can't find if there is a tyre preasure re-set button?. Going on a long trip soon & will check tyre pressure so if they do need an increase i will need to do the re-set if there is something. I seem to have a yellow flat tyre symbol when i turn the ignition on (goes off after it's done the checks) so this made me think if there is some sort of tyre pressure monitor system?. Just to add mine has the Virtual cockpit.Thanks in advance.
