TPMS Valves

After two faultless weeks in my ownership, woke up this morning to a flat nsf tyre. Soapy water investigation after reinflation revealed the tpms valve to be blowing bubbles. Some judicious poking and prodding of the valve seat stem seems to have it seating correctly and holding pressure.
However I don't want to risk this happening again, so is it possible to replace just the shraeder section of the valve unit? it looks although this section can be unscrewed? Either that or remove the tpms unit completely and replace with old style rubber valve stems (assuming they will fit).
TPMS has previously been disabled, so looking for the most cost effective option.
Thanks in advance for any advice.

If your TPMS has already been disabled, then you can just replace with rubber valves.

I did that on my old car - those valves are very prone to corrosion & failure - I was glad to see the back of them.

Any tyre place can just remove the TPMS ones & pop some standard rubber valves in.

You used to be able to unscrew just the valve (most tyre shops do this to let the air out) is it not possible to just replace this? 2011 TDV8 Vogue SE

This is just a WAG (Wild A$$ Guess) but it does appear that there's a fair bit of corrosion on the top of your valve stem. I've always been in the habit of keeping a cap on my valve stems.

I even bought a set of these for my RR: https://rimmerbros.com/Item--i-LR027663

Would keeping a cap on the stem help to prevent the valve insert from deteriorating and if there was a small leak, maybe even hold in some air?

I do remember on my old Honda Pilot that the valve on one side of the AC system was leaking but my tech didn't notice this until he removed the cap. It was a very small leak but he caught a slight whiff of the Freon. It was the cap that was preventing it from leaking or at least slowing it down.

Of course, this won't help you now but maybe could be cheap insurance for the future.

Good luck!

Yes, I always keep the cap on - only removed for the photo shoot! The thread is actually quite worn, to the extent that the plastic cap thread barely catches. Not sure if this is due to corrosion or possibly a non-compatible metal cap being used sometime in the distant past. 2011MY 4.4TDV8 Autobiography Baltic Blue

They corrode, badly.

I had one snap when I was trying to remove the plastic cap - that's when they got binned and I returned to rubber. The later valves on the L405 seem to be more robust.

If TPMS is disabled, then get them replaced with rubber ones as soon as. They have been know to break and if they crack ot break when driving you don't want to end up wrecking a tyre or alloy.

fist thing I did when I got an IID tool was to turn off TPMS and replace the valves with rubber ones 56 TDV8 Vogue SE

Thanks everyone for your replies and advice. All replaced with old style valves today. One less thing to be paranoid about! 2011MY 4.4TDV8 Autobiography Baltic Blue
