Had the same problem with my 2005 s type,I bought a reader from amazon cleared the cars memory then cleaned the sensors never had a problem since hope this has been helpfull
My s type keeps loosing water I've changed the header tank but still it leaks I've seen traces of water down near the left front wheel so I removed the under tray but I cannot find a leak for love or money the car does not over heat just every few days it puts the low coolant light on can anyone help?
