Hi

I drove my XF from toronto to windsor today which is about 400kms and the need went a little bit over the half way point when i got to windsor. i thought the problem was with the long drive, so i turned it off when i parked it for 2 hours and then went out for a spin, and the temp needle would go over the half way point just a tiny bit, and then would go under the half way point, never had the problem before
