Anyone know how long the batteries in these last for before they need replacing?
Mine are 11 years old now and still work fine

I wasn’t aware that they had batteries.
I thought they responded as RFIDs to the external signal from the detectors ( like contactless credit cards).

The WS manual for a L405 states otherwise, would presume L322 would be similar?
But maybe they are not changeable and a new sensor is needed if one fails?


The tire pressure sensors are self contained units
If a tire pressure sensor battery fails, the sensor stops transmitting and the TPMS transmits a message to display for
example: 'FL Tire Not Monitored'. The retailer should interrogate the TPMS using the Jaguar Land Rover (JLR)
approved diagnostic equipment to determine the cause of the message. The TPMS wheel unit maybe in ‘Ship’ mode
and a handheld Low Frequency Tool can be used to turn the TPMS wheel unit on into ‘Park’ mode. If the sensor has
failed, the sensor must be replaced and the stored faults removed using the JLR approved diagnostic system. 2018 SE SDV8 4.4 Byron Blue

they have lithium ion batteries and they are supposed to be good for around 10 years .. ... - .- -.
