I have a new set of sensors from ebay for £33, but they came without the nuts.

Seller is supposed to be supplying, but I've lost faith. I will update my original thread with the eventual outcome

I understand the nuts to be one time use only, hence is anyone able to supply a set of four?

I've only been able to find TMPS refurb kits for about £9 per sensor, which seems a silly price when all I need is the 50p nut.... 2007 Zermatt Silver TDV8 Vogue SE - now sold but was a great car!

If you can ge hold of some please take the dimensions of them and we can possibly save people agro in the future

failing that TPMS can be turned off with about 30seconds of time on an autologic or MSV2 or maybe the IID as well  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Think LR do a rebuild kit including a new valve stem for about £10 per sensor.
Potentially saving the dilemma of the TPMS light coming on.
I guess you would have to consider the age of the sensors due to battery life.
It may end up more economical to buy new sensors.
Of course when you buy off eBay you don't know if your buying an old sensor fitted with a new valve stem.
Dan @ Duckworths supplied me with 4 new ones, they synced to the car with no problems. TPMS light straight off.
Glad I went new in the end, peace of mind when it's £5-£10 per wheel for tyre fitting and balancing.

Edit: sorry just seen you already knew about refurb kits. That paragraph blended in with your 'signature'  
Had it, loved it!
