Tyre pressure sensor fault

[M3petHEAD]

Hi all,

i brought e46 m3 a few weeks back, and it had a tyre pressure sensor fault, tried resetting but it pops back on and the tyres are all fine.
Is this a mot failure? is it a easy fix?

any info welcome

It might just need reset for the tyres. Were they changed when you bought the car?
With the car stationary, press the button so the warning light comes on. Drive it for a bit and it should then go off itself and stay off.

Have you followed the exact instructions for resetting as detailed in the manual? It's not as intuitive as it should be and so if you are just performing a reset by using the button then it will keep coming back on - I've recently swapped all my tyres and have had this very issue. But follow the instructions and it works and my hasn't come back on since.

No foolishly I haven't, I just tried the button that turned it off and it just pops back on. Ill give it ago this morning.
Thanks
