After checking tyre pressure have you reset the monitor on the dash ?
Customer: replied 15 days ago.
but it happens every time I start the car
Ok so the next step is to test the valves . A special tool will be required to see if all the valves are communicating
Customer: replied 15 days ago.
Would this be the case if the tyres are not run flats
Shouldn’t have an effect but the valves have an internal battery that after a period of time fails and the valve has to be replaced and testing with a special valve test tool is the only way to check
