Just to resolve this and to give an answer to anyone who comes across it. The issue was... too high a tyre pressure... duh! Thanks to all for your suggestions.

I need to get a 2016 Fabia Estate through an MOT at the end of the week. The Tyre Pressure light is on, accompanied by a "There is an error with the tyre pressure monitoring system". Is anyone familiar with this fault. Unfortunately, I can't get to the vehicle till just before the MOT and am wondering whether it will go away with the reset button in the onboard screen, or if this is something more sinister. No other warning lights showing, tyres in acceptable condition and only around 25k miles. Tyres were aparently pumped up 4 weeks ago and system reset but warning has been appearing for the last 3 weeks; owner has not tried resetting the system since the warning has appeared. Any pointers warmly welcomed!
