Yesterday my tyre pressure warning light came on, so i checked all the pressures and one was down to 22psi.
I have fixed the puncture and set all 4 tyre pressures to 34psi, but the light was still illuminated.
Several trims down the motorway and around town haven't made any difference, its still on, so, what do i do to reset it, or does it suggest a there is a problem elsewhere?
