There’s an air leak in one of the the TPMS wheel sensors on my 2013 C5 Tourer X7. It takes a couple of weeks for sufficient air to leak to illuminate the low tyre pressure warning system. When washing the wheels I can see a few air bubbles around the valve stem, signifying the leak.

Do I have to buy a Citroen replacement TPMS sensor complete, or is there a quality after market equivalent that would be suitable. I’ve seen just the valve stem, washer seal and valve core available for £5 or less, including one kit on eBay,which quotes a Citroen part number. Have you tried these, and are they suitable?

I bought front sensors for my Mk1 C5 as they can't be turned off in the BSI.


Citroen don't make them and they're made by a big firm that do them for a large number of companies, as I understand it. 


The new sensor needs to be coded in.


Alternatively, as the previous owner did for my 2008 C5 X7 Tourer, as there was a batch of very poorly made sensors, he had them all replaced with normal valves and the feature switched off in the BSI.

Citroen do a repair kit for the valves but there could be Schraeder or Siemens make of valves used. You would need to check if these fit either of them. You need to remove the tyre and then the valve to fit the new parts so could be worth doing this if a new tyre is being fitted. https://www.ebay.co....1205/1316344979
