I've owned my 2016 Astra for around 4 months now. I was driving at a constant speed on a motorway the other day (as you do). One of my sensors showed that my tyre pressure was down to 31psi. Warning came up on dash. I thought I better stop somewhere safe to check it. However 30 seconds later. The correct reading on that tyre came back to normal. Dash warning went off.
Are these sensors effected by occasionl faulty readings? Is it more likely to be a valve or sensor fault?
