Reset Tyre Pressure Monitoring?
Discussion
My Spyder keeps on warning me about low tyre pressures (sometimes stating by as much as -6 psi).
I do not mind this if they are really that low, and I do set them at -3 psi "cold" as the pressures quickly get to the right level as the tyres warm up.
I have checked pressures independently, using an electronic gauge.
But even when they are at the correct pressures (hot) according to the MF display, I still get low pressure warnings, every so often whilst running.
This undermines the usefulness of the system, as I might well ignore a justified warning.
Is there a reset process hidden somewhere?

I am bumping this - yesterday whilst running in pretty hot (for UK) conditions, my pressures went from 26/29 (set "cold") to 29/32 fairly quickly.
This was displayed on the MF display, and given that the recommended pressures are 29/33, all good, yes?
But no - the MF display kept giving me low pressure warnings, sometimes stating as much as -6psi.
How can it display the actual pressure, during the drive, with just -1psi shown on the rear tyres, yet flag under-inflation of 6psi?
Ideas please!

Mines has done this as well after a trackday where pressures were adjusted. Can’t remember where I read it but the “fix” that has worked for me:
Set pressures to what they should be, go into TPM menu and toggle to winter wheels, come out of that menu, go back into the menu and toggle to summer wheels
Settings can only be changed when stationary and it sometimes takes a lengthy drive (sometimes 20mins but normally less than a minute) and all warnings disappear. Seems to be a bit of a glitch.

Mine did this for the first time yesterday. Exactly as the OP describes. All pressures correct for each corner but kept giving a -4psi warning on one corner.
I did as above and set to winter tyres then back to summer tyres and then did the running required to set the new values.
Worked fine after that and again today.
Strange as I’ve never seen that issue before on any of my cars with this system. Funny that it happened yesterday and saw this thread today.

Well….I tried the routine described above, including switching off the ignition, removing the key, after confirming the S to W change.
Then reversed the process to get back to S
Something was definitely going on, with re-learning because the 4 pressures did not appear for quite a while (a couple of miles) but before this - almost immediately after driving off - I got the -4, or -6psi warnings.
And this continued after the tyres were warm and displaying 29/33.
Vexing….

So fixed now?
No, unfortunately not.Still getting the same warning messages - usually -4 or -6psi, even though the pressures shown on the MF display were 29/33, as per the book.
Given the consistency of the warning numbers, always -4 or -6, but never -5, this must be some sort of software error.
I will try again tomorrow, but let the system learn as if they are Winter tyres, then when I have pressures displayed, wait for the errors.
Then reset to Summer tyres and let the system learn again
So strange.
After never having seen this before, it did exactly the same thing again today. -6psi on right rear, the same as the other day.
Reset again via Winters/Summer sizes cycle and fine for the rest of the day.
As before, never seen this on any of my cars before. Just started in the last few days.

Probably that there Climate Change thing....;-)After never having seen this before, it did exactly the same thing again today. -6psi on right rear, the same as the other day.

I reported the same on the 4.0 GTS thread a few weeks ago (and got no replies), so I am glad i'm not the only one. Drives me nuts, and does it every time I drive off. Always the front near-side wheel and always -0.6bar.
Sometimes it will reset during a drive, then come back on.
Yours might be resetting as I have noticed that my tyre pressure increase after several miles of driving.They can rise as much as 5 psi on a hot day.Sometimes it will reset during a drive, then come back on.
Hve you tried (i'm sure you have) resetting your tyre pressure when cold by 1 psi all round, doing a TPMS reset and see what happens?
I have done the full reset process 2 or 3 times now, including driving on the "W" setting until the system has "learned" the change, then back to "S" learning.
Now the weather is much cooler, I have raised the "cold" pressures to -3 psi relative to the recommended settings.
On driving for a few miles, the pressures come up to within 1 psi of the recommended settings, but I am still getting error messages.
Crying "wolf" is the expression that springs to mind.
