Hello XF-Driver, who of you also has the TPMS and how do you solve it with summer/winter tires? I am annoyed a little bit that I ordered it at all, because it is not such a nice toy as in the Audi (there you can display the pressure and temperature on the monitor for all four tires) but a quite banal warning system. For the 2nd tire set you need basically also a 2nd set of sensors. I have put the winter tires on the 18” rims with which the XF was delivered (for the summer then 19” on it). Therefore, there are now also the sensors on it. Have asked already what a sensor costs: 54,86 plus Mwst. (so a set about 260,- Euro incl.) Now comes the joke: The things are from Siemens VDO. And I have asked once a friend at Volvo whether the possible construction is true, since I had found the following on the web:Jaguar-TPMS Volvo-TPMS My friend has not seen what a Volvo is costing, but a bit of a bit.
