Hi all, I have been having TPMS (tyre sensor) errors for the last 2 years in that the sensor keeps on intermittently coming on and off even though the tyre pressures are fine. The car (2010 XF) has been into both Jaguar and independent dealerships over that period and they can't find out what is wrong. the last time it was in they replaced one of the sensors which worked initially but then a few miles down the road it came on again, also they did a software update which I believe came from a bulletin. The error message is not on any particular wheel, when it comes on, generally it cycles through all 4 wheels over and over again. Obviously I have lost all confidence in it so it is useless and annoying. Has anyone seen this before or have any helpful hints? Thanks Russ PS: Hello by the way. I am new to the forum.
