False TPMS Alert

We know 
Perhaps when the alert came on one tyre was at a different rotation and then shortly after when it warmed up they were the same, hence why the pressure on the front axle was the same and the pressure on the rear was the same when I checked a few minutes later.
Just keep checking your pressures regularly, as you're doing, and accept the system is fallible.

My X3 does this occasionally ... seems to be weather related in the main
I just reset it occasionally as I do have an old habit of checking tyre pressures once a month anyhow (as I was taught many many years ago)
Still goes off a couple of times a year though ... Not really a bad thing if you are not in the habit of checking pressures much

911 gives pressure and temp…. Never had an alert.
Wife’s macan gives pressure, had to have everything tpms related changed after buying the car, front left was reading rear left etc, then warnings when senders lost connection etc.
Could be a sensor issue? I note yours may be based on rotation? Abs sensor playing up?

No issues I don't think.Could be a sensor issue? I note yours may be based on rotation? Abs sensor playing up?
If any one tyre fluctuates by 3psi, up OR down, it gives an alert. Just the way it works I think. Annoying because it can give a false positive if the tyre pressures increase during a journey

Welcome to MAzda TPMS - we had a nightmare with our Mazda 6 over our many years of ownership.
They are really sensitive to differences between tyres. Mazda have a solution where they reset the system then take it for a constant 50mph drive for 20mins, but it didn't cure ours. It was in and out for years trying to fix the fault. In the end we just used to ignore it and mute it everytime. Terrible system.
You do have to make sure you change tyres on the same axle at the same time, expensive if you get a puncture. Mazda's solution suggested to us was to change all 4 tyres - at £200 for each wheel!

Thank you for the helpful information. Yeah these mazdas are great to drive but do have their own flaws ( as I'd assume most cars do )They are really sensitive to differences between tyres.

Tyres are all pretty much brand new Michelin PS5s.
At least you can empathise how annoying it was to worry thinking I had a flat tyre when everything was completely fine.
3 times since owning the car the light has come on, and only once was it actually correct. Owned the car for 4 months
First time down country roads the tyres got hot and gave a false alert.
Second time was a lifesaver because I actually did have a fast puncture which thankfully got fixed
Third time was yesterday down an A road when it was a false alert
Difficult to just ignore it, especially on fast roads where you have to wait for an exit to actually check the tyres and not knowing whether it's another false alert or not.
If only it had direct tpms where you can monitor the tyre pressures via the cars infotainment system. That would be an ideal solution

You're making the assumption those systems don't have issues as well.
Are they not more reliable generally though? Edited by cuprabob on Monday 27th February 18:37

20 minutes down the motorway the light comes on. Got to my destination 25 minutes later, tyre pressures were all fine.
Reset the light, drove home, no tpms light. Same as last time
Would it be best to take it to an indy or would it have to be mazda ? I am under warranty, but their "diagnostic" charges are ridiculous.
The only pattern I can see is when driving around town, no issues. But if I set off on a longish journey on the motorway or a-road, the light comes on half way there.
I have no tpms valves, it's the indirect system which uses the ABS sensor I believe.

As usual No light for 10 days or so. Until I hit the same long A-Road today and it came on.
Driving round town, no light. Driving on fast long roads, light comes on
The baffling thing is, it comes in on the way there, then i turn the light off and it stays off for the whole journey back
Worth contacting mazda or not?

d!With the current hot weather, the TPMS in the Jazz has been crying wolf everyday.
So every time it goes off, I take my hands off the wheel to make sure it's not pulling from a deflated tyre. Pull over and perform a visual check. Then get the tyre gauge out and tyre pressures should be 33 psi all round, but with the heatwave, the tyres in direct sunlight had increased to 37psi and and 35 psi for the others.
