Got a low tyre pressure warning. All were at 42 PSI except for back left which was 40 PSI. This seemed high so put them all down to 34 PSI. But the “Perform Reset” was greyed out. I was in park with engine running. Drove around for a bit and tried again but still won’t let me start resetting. Warnings stuck on the dash. Anyone know anyway to fix this? Wheels have been swapped to Style 351s by previous owner.
RPA TPMS is the older version right? Meaning it uses ABS Wheel Speed sensors not the actual TPMS sensors right?

You need to be driving to reset tpms..

Drove around for 20 minutes and it stayed greyed out the whole time

Went and put all tyres back up to 42PSI but that didn’t help either.

It could be a sensor problem but try putting in a lil more air in the tires, and then bringing them back to 32-34psi. Drive for 10-15 mins. Then go into iDrive screen to check tpms. Hopefully it's something simple.

The only sensor problem that should cause the reset to be impossible is if they're the wrong sensors. If that was the case they shouldn't work at all. It's probably going to take a diagnostic tool to find out what the problem is.

Did you by chance code iDrive to show tire pressure and temp?

OPs screen specifically says must be stationary.

[Fliplegend]

Stationary to start the reset but driving to complete it.

I see the problem...TIRE is spelled incorrectly.

I have the temperature reading enabled. I tested it today and it didn't affect my reset.

this happened to me before i tried everything including new tpms sensors and nothing worked. ended up getting a software update from the dealer and it fixed itself.

You legend! This is what it was, completely forgot I put that on. Used Carly to put it on a few weeks ago, never worked so just assumed it done nothing and forgot about it. But when I turned it off and restarted the ignition the Low Pressure warning was gone and I was able to select Perform Reset, 20m drive and it was reset. Thanks a lot mate. Thanks to everyone else for the suggestions.
