Mine came on last night right as I was getting home, so I checked my pressures this morning to find one of my tyres was low....Ive topped up the air and the light is still on. Does anyone know when the warning light should go off when the tyre/tyres are inflated? immediately? within minutes? or is it still on because The sensor cannot find a constant air pressure, meaning I have a puncture?

Hold in the button next to the hand brake and it will reset

Cracking. Thanks. i'll give that a go. *learns something new every day*

Same happened to me, the button next to the handbrake didn't work. The warning light would go out but come straight back on, not sure if it was a fluke but i read somewhere that ignition on and hold the button next to handbrake as well as Traction Control button at the same time for 2 seconds. Worked for me and hasn't come back on.

you need "just" the ignition on (not engine) when you press the button to reset.

Just tried the above - ignition and button only and it seems to have sorted it. will confirm when i drive again in the morning.

thats exactly how you do it x4cs, happens to me everytime i change to my winters
