Tyre pressure warning light won't go out.

[The Purple Cow]

I have a 2018 NX300h. The TPMS warning light burns continually no matter what I do.  Obviously I've checked the tyre pressure on several occasions and they are all fine.  Reseting the TPMS on the steering wheel cuts the light out for about five seconds, but then it comes back on. I don't know what else to do, I can live with it but it's driving my wife scatty.  Anybody have any ideas? Would disconnecting the Battery for a length of time help?

Do you get the following confirmation message (from the handbook)?

No

Is this the process you use? Note the "press and hold"

[The Purple Cow]

Yes I followed the process to the letter about half a dozen times.  The light goes out for a couple of seconds then comes back on.

I think the system will need checking, get the codes read. You might be able to live with it but it will be an MoT fail ..

One of the sensors has likely gone or Battery will be dead.

TPMS sensors have a shelf life, so maybe yours needs replacing as it's 6 years old.

Maybe the pressure sensor has broken away from the valve

Thanks for the useful advice all, I've booked it in for a fix on the 27th.
