Hi,
See below from previous discussions.

tks.

It is not Jaguar specific. Ford has experienced issues. The relevant statistic would be accidents caused by tire blowout. One poster on this board experienced a sudden loss of tire pressure but the TPMS unit was destroyed in the incident. The remains did show a broken valve stem. UK posters have reported failure while adding air to the tire.
Jaguar has updated the part and declares that only plastic valve caps are to be used.
The is a real hazard, potentially very dangerous. You would be extremely foolhardy to ignore this problem, especially relying upon anecdotal evidence or personal unskilled observation. Comparison to other makes, particularly predating TPMS use is also specious.

Here is the text of a communication from Jaguar:
Concern:
Jaguar has received Warranty claims for TPMS valves/sensors which have been broken whilst
attempting to remove metal valve dust caps from the tyre valves.
Cause:
Metal valve dust caps corrode onto the aluminum TPMS valve stem and become difficult to remove
without breaking the tyre valve.
Action:
Jaguar engineering do not recommend the fitment of metal dust caps to vehicles fitted with TPMS and
warranty claims will not be accepted. Any vehicle found with metal/chrome valve dust caps on TPMS
tyre valves must be removed and replaced with the Factory fitted grey plastic valve dust caps, part
number XR8 51652.
Owners must be informed of the consequences of putting metal valve
caps on Aluminum TPMS tyre valves.
Hope that helps!

Plastic Valves
i think...Jaguar has updated the part and declares that only plastic valve caps are to be used.
