Hello,
Advice sought please on how to rectify this fault now showing on digital display - the tire in question is fully inflated.

Many thanks,
John.

Without a few more clues I'd guess that the sender unit in the wheel is on the way out. Your only options are to replace it or ignore it. Somewhere on here there is a thread with some of the different types of sender identified.
You can buy a replacement off Ebay, but you need some special kit (not a lexia) to fit it.
With a Lexia you can get it to ignore all the senders, so you dont get the warning - which is another option.

The TPMS (tyre pressure monitoring system) valve might be faulty. You need a Lexia to check this and also a TPMS exciter to resynchronise the valves to the car. You might be lucky and find it just needs resynchronising but I doubt it.

Many members here have a Lexia but AFAIK no-one has an exciter, although one member managed to borrow one. I used my Lexia to turn the TPMS option off to avoid the nag message.

Thats what I did on mine, turned the warning off with a lexia.
