I am having the 2 front tyres on my 2014 Freelander 2 Metropolis changed on Monday. The car has the factory fitted TPMS system installed. While the tyres are off, is there anything I should be doing to service the TPMS sensors - like changing the batteries? Thanks

Good question. Didn't know they came with a TPMS (option?) system from factory - damm good option, wish I'd had 1 on my F1 before the transmission blew. Mind you, I still might not have understood its significance!

Found any more hills to skate down?

Can remember that happening in my D1, scary as.

no that only happened the one time - I've been careful to steer clear of icy hills since then

TPMS is standard on some models of FL2, and an option from 2008 MY onwards.

It's a good option, which I'd consider retrofitting if it's not too difficult.

As for batteries, I'm sure I've maintenance in the service manual.

I've checked the owners manual but that only covers normal operations and error states - there's nothing I can see about maintenance. I did read somewhere that some TPMS sensors are sealed with lithium batteries which last 5-10 years. If that's the case then I'm about out of time ...

It's in the LR service operations manual, not the vehicle handbook.
According to the service manual says the batteries aren't replaceable, so new wheel transmitters are needed if the internal battery fails.

I called Harwoods this morning to check. Apparently the TPMS sensors fitted to the Freelander 2 (presumably other Land Rovers as well) have no batteries. They generate their own power on rotation so no maintenance required. Clever!

Thanks for checking. Maybe it's a rechargeable battery that stores the power generated through rotation?

It would be nice if it were, but I suspect it's a long life Lithium cell, something similar to a camera battery of old.
The description says the sensors shut down when the wheels stop rotating, so presumably they have some form of centrifugal switch inside.
