Confused about TPMS valves

Sir_Pigley · 10-10-2023, 09:24 AM

I have bought a set of wheels (without TPMS valves) so that I can put winter tyres on them.

However I am confused about what to do regarding the TPMS valves.

The tyre shop is quoting £silly monney to supply, "program" and fit valves.

Rybrook BMW say that no programming is needed. Just put new valves in the wheels, perform a rest and the car will pick up the new valves automatically.

Elsewhere on this forum soneon has said that provided the valves send a signal at 433MHz the car will pick them up automatically.

There are sets of 4 x 433MHz TPMS valves for sale on eBay for around £45 which claim to be compatible with my 420i XDrive and 640d.

Does anyone know what is the truth of all this?

Can I just but the eBay set, have them fitted and the car will find them automatically?

Based on my experience, it should detect them automatically.

I swap between daily and track wheels, each with their own TPMS sensors. Sometimes, the car doesn't detect them right away, and I'll see the TPMS light; but with no action required on my part, it will usually resolve itself next startup.

If I were to do it again, I might save the $ on the track TPMS sensors and code 'em out, but the TPMS works pretty well in my experience.

FWIW I've been driving for the past several years with the TPMS light on my dash and been fine lol.
