When I asked about a sensor for my full size alloy spare, I was told only four can be programmed in. It stands to reason that a fifth sensor in the boot would confuse matters. Mine's a Vauxhall/peugeot thingy, which do not have batteries, so yours may be different.A month before the MOT is due my XE has fallen out with one of its TPWS sensors.Just one?
Might be worth swapping wheels around to prove it to the sensor or the initiators. Most likely the sensor. I've yet to have a sensor fail mind, but I think the battery life is quoted as 7 years. I've bought a couple of packs of 4 from egay in the past, paid around £40 for 4 both times if memory serves, but I bought them when I didn't need them, so could wait for discounts...
Yep, just one, and I have a feeling it's the wheel that has an aftermarket sensor, as I bought a spare wheel and pattern sensor shortly after I got the car. I do need to rotate the tyres anyway, so will find out if it moves with the wheel then. I suspect the recent morning frosts have been its last straw.
Yes, the Jag ones have batteries in, and the car figures out what sensor is on what wheel with no need to program them.
