Hi, I keep getting Tire Pressure System Fault warning on the display of my 2008 XF. I’ve have it looked at by a Jag garage and KwikFit, they sync all the sensors and warning goes away. When I drive the car for approx 30-40mins, the warning comes back. I did have the valves and 1 TPMS module replaced (by KwikFit). Anyone else had this issue? How did you resolve?
