Warning light appeared on dash.

A warning light has just appeared on dash I’m miles from anywhere outback. Should I be worried?

That’s a tyre pressure warning light, it means one of the tyres has lost some pressure, it often happens on long journeys. Obviously it could also mean you have a flat tyre/ puncture.

Oh my - Thankyou so much. Out with the compressor and check what’s up. Much appreciated, Polomint.

If you need to put air into the tyre you will need to reset the system, it’s an easy process.

Do you have a “vehicle status” screen on the instrument display menu? If so you maybe able to scroll to a screen showing tyre pressures. Also if you do need to add air and you have the same display you shouldn’t need to do any reset…. The TPMS system updates the screen when you drive. Yours might be different!

It’s quite a sensitive measurement, and can be triggered with temperature change. We carry a small pressure gauge to check without getting the compressor out. Happened to us last week on a hot (by uk standard) day - but each tyre was on or abouts the required setting, so I reset the pressure to current values. Checked again when tyres were cold, all okay.

How do you do the reset? My T5 had the “non” TPMS system which did require a reset but my T6.1 does not and displays ”live” pressures.
Agree about the sensitivity…. Had a warning showing low pressure on rear left even though the display showed pressure was fine.

No manual reset on my t6.1 Ocean.
A short drive after inflating/deflating the tyres resets the TPMS.

On T5 and T6 you only have the option of indirect TMPS (in the UK not sure about other regions) - this uses the wheel speed (ABS) sensors to determine the number of wheel counts per revolution as a way of determining the tyre pressure - it is very rough way of determining (inferring) tyre pressure and they have a “reset” which is a way of the customer stating that the tyre pressure is correct and thus a reference point for the system to use, this system is called “indirect TMPS” as it infers high or low pressure via a change in wheel speed vs when the customer hit reset which is the reference.

The other system know as “Direct TPMS” (option on T6.1) uses sensors in the wheels to measure temp and pressure directly - the only variable is what tyres are fitted and load - thus what is the correct pressure- these systems normally have a metal/ alloy valve (although the very latest systems have gone back to rubber stems) .

The rules around when a warning is triggered is a standard piece of legislation (for EU inc UK) that determines the operation. For slightly below pressures (or high which is normally solar load ) you normally get a warning at 10 Mins after journey start, this is to allow for temp related swings. Big deviations trigger an instant fault. Most of this stuff is due to the issues in the USA decades ago where low tyre (tire) pressures where deemed a factor in tyre issues

I’ll remind myself and let you know. It was similar/ same menu option as my wife’s old golf which is how I found it.

Okay, this is how to reset the tyre pressure set point using the infotainment screen:

Vehicle Status screen, press ‘Settings’ bottom right.
In Settings screen select ‘Tyres’
In Tyre Settings screen select ‘! Set’

Sorry it’s taken me so long., just remembered.
