Only had my S Type for a few weeks and slowly getting to know it, had a set of Powerflow end cans made and fitted and am very happy with deep tone that lets the v8 burble out, also fitted a K+N air filter element
one problem though, there is an alert on the computer screen "Coolant level low" but looking at the header tank the level is spot on and the temp does not go over the halfway, could it be the sensor or worse ?
