Hi,
I had covered about 150 miles today when a warning message came up between the dials and a beep - but traffic was heavy on the M6 so I could not read it before it went, then the yellow tyre pressure warning light was on. I limped to a service area nearby off the motorway, all 4 tyres looked and felt normal.
I rang the dealer who supplied the car and the person did not seem to really know, saying if it does not look like a punchure, just check the tyre pressures and then reset the system.
I did that and it has not come back on for the next 50 miles driven.
Anyone else had this happen? - would the heat of high speed driving set it off too as I guess the pressure may change and is the sensor too sensitive?
