I have just purchased a set of original BMW TPMS Valves to be fiited to my Summer Wheels, the TPMS Valve that came with the car are on my Winter Wheels.
Although both sets of valves show the same part numbers i have noticed that the numbers printed on the valves just above where it says 433Mhz are different, on my original set they show the number 22 but on the new set three of the valves show the number 31 and one shows the number 32 as shown in the photos i have attached.
Any idea why this is??
Original TPMS Valve
New TPMS Valves
