Going to replace tyres soon. But car is not very old & low miles. What is the story on these? I assume battery powered? Do batterys have a life in miles or time? Do they go into a sleep/energy saving mode when car not in use (like my cycle computer) Do you replace (or do the tyre company) replace batteries on full sensor? I have seen sensors for sale & there not to pricey but tyre companies charge you for a normal valve (which I assume they don't have to fit)
Had a search online & generically they were talking 5-9 year with 7 years being target & talking about 100k. Sounds like they do work more with mileage. Also battery is integral and whole unit is changed. As I said this is just generic info & not related to Renault in particular. When did RS start getting them fitted?
