Tyre pressure warning light - any advise?

[IDNB]

Apologies if this topic has been covered previously, but I'm having an issue with a tyre pressure warning light on my 2022 A110GT. The warning to adjust tyre pressure appeared. I checked the pressures - all good. But it won't let me reset the system. I've read and re-read the manual and gone through the process as directed but no joy. Maybe I'm being thick. I haven't consulted the dealer yet. But has anyone else had this issue? Any advice welcome.

Have you tried driving a mile or two on straight roads after resetting?

I don’t have my car yet, so not even sure of the reset procedure, but I imagine it works on detecting different rotational rates between wheels to determine that one is under inflated, and might need the drive to recalibrate?

If it's the same as on my Megane you do need to drive it round the block to reset.

Yep, tried that twice. I just get the 'Tyre pressure SET unavailable' warning message.

Completely different car I know, but on my Vitara, you had to adjust the pressure otherwise you couldn't reset it.

Try all the previous suggestions (it sounds like you have) and then wait: the electronics seem a bit buggy. The stop/start function didn't work on my MY 2022 Legende yesterday, but may do today. Or may not (Gallic shrug). Just as the satnav went mute for a couple of hours despite following the handbook to the letter on how to unmute it; it reset itself when it was good and ready.

Of course it could be that a wheel sensor (and/or whatever picks up its signal) has failed, in which case it's a dealer job...

I had a similar issue last year - I had to set them slightly over the minimum pressure and then the system let me do the reset

Not teaching you to suck eggs, but stop/start won't work if the battery is too low.

Mine is exactly the same.....i might try disconnecting the battery.

The car gets frequent use -not quite every day, but close to it- so I'm not sure the battery is low; there's always the possibility of 'that' alternator problem, but a) it's a MY 2022 car (did the fault affect earlier cars more?) and b) I'm due to drive to Devon and back (from St Albans) in the next few days, so would like to stay in denial if I may...

I changed the original dust caps and started to have these issues, changed back and problem went away

Thank you for all the advice everyone. Strangely, just as LE62NGE predicted, the warning light has now gone out of it's own accord.....weird. Maybe it just got bored of being on and being ignored.
