My own fault totally this one, kerbed the bloody rear wheel whilst reversing up my road total doughnut was in a rush and mind on other things. Damage is minimal and wheels need sorting anyway so I'm not too worried about that side of things. However, the tyre pressure warning light came on red - most annoying. I turned the car off and left it for a while, light still on. Have also checked all tyre pressures and they are as I left them. The tyre hasn't deflated at all.
Is it possible to reset this without plugging into diagnostics?
Oh and tyres are conti sport contacs 3s (not M3s) if that's useful
