What’s the reason you need to replace? The reason I ask is that my tyre fitter is able to replace serviceable parts in the TMPS. Depending upon the issue, it may it may not necessitate a replacement valve.
Sorry for the delay,been stacked out…..
The one tyre is losing pressure. Not vast amounts just enough to bring on the tpm.
We had them crappy aluminium dust caps on and they seized when I tried to remove them. I used a touch more force than I should and slightly turned the centre valve and it’s been like this ever since.
