Has anyone experienced a tyre pressure sensor fault on their ZE50? I've had mine less than two weeks (820 miles covered) and got a sensor warning on my front-right. Well, when I say warning, the pressure reading was gone completely. About a minute after that the front left reading disappeared as well.The rears are still showing a reading. The tyre pressures are fine. Is this one of those faults that will disappear or do you think the sensors have failed and I'll have to take it to a dealer to get sorted?
