I got a low tire pressure warning.

I inflated the tire.
The numbers are now correct, and according to the compressor readings,
but every time I start the car I get a low tire pressure warning.

The low pressure tire, is now the high pressure tire, but it is still Orange.

It's like the "Error Flag" has not been reset.

Anyone else experienced this?

I have tried to look in the menus to see if I can reset the Warning, but has not found anything.

Usually if any warning message comes up on the driver info display you have to press the 'Ok' button on the steering wheel to dismiss the message.

I have driven the car "100 times", every time I push the OK button to dismiss the message.
The car work OK but its annoying to have to push the OK button to remove the message.

Perhaps you can go into the vehicle menu and do the TPMS re-learn procedure like any tire shop would do when rotating tires. Then use a TPMS tool like the one pictured to perform the re-learn. Not that you should have to do that but may be better than going to dealer.

What do the tire pressures in the car say? Post a picture of the TPMS screen on the radio. Does it say "low tire pressure" or does it say "TPMS fault"?

You don't need to do TPMS relearn these auto learn.

Here is the warning screen:

Ford Mustang Mach-E Low tire pressure warning don't disappear Bilde_2021-11-17_143447


It's Bar (metric) not PSI

"Dekktrykk lavt" means "Tire pressure low"

It is no fault indication of TPMS

There is no other info on the "big screen"

The car will soon go to the dealer for glass roof and window check, so can ask dealer then...,

Hmm, EU only issue?
Worst case try pulling the 12v negative for ~30 minutes. Excessive but I think it might force it. Unless you have a ODBII scan tool possibly.

For giggles, can you change just the bar to psi? (Not sure what the localization is for that, if it's the entire car changes to non-metric)

Fill all your tires to the correct pressure and drive the car several km to clear the warning. If the warning doesn’t clear, then you might have a bad sensor.

If you have had a pressure failure logged, remember to reset the fault in the menu on the screen in the car ?

Hello, I'm reviving this thread, I'm in the same situation... did you find a solution? I just drove 15km and the warning light is still on despite inflating the tires.

Sorry for the automatic translation.

Finally, after two days with the light on, I deflated it to 1 bar and then reinflated it to 3 bar, then back down to 2.5 bar, and the light went out.
