TPMS sensors Torque Setting

[E55BOF]

Good evening all. I've just had new wheels fitted to the CLS, and the TPMS sensors were swapped over. The rear right is losing a little air; not as much as it was before I tightened the TPMS sensor/valve stem nut a touch, but it's still not quite sealing. Could somebody please be kind enough to let me know the torque setting for the 11mm nut that holds the stem into the wheel rim?

Think it’s 7nm but don’t quote me.
Sometimes need a little bit of sealer or renewal once been off/on.

Thank you for that. Could I trouble you for the part number, if you have it?

I've just had the new rubber 1s fitted to my new wheels, so no corrosion or marking them

When I transferred mine over the fitter told me I should get some replacement stems because the seals will not seal against the rim properly. I was able to eBay a set for my tpms sensors; about £15 if I recall.

The tightening torque is 4nm. I don't have a torque wrench that will go below 8 nm, so I just nipped it up a touch - quarter of a turn if that - and it seems to be holding pressure.
