E60 E61 E90 E92 OEM TPMS and VALVES for sale
 

These came off a 2010 535. It's the sensor plus the valve stem. They have only been mounted (and taken off) once, and had about 28,000 miles (45,000 km's) on them, as they were on my summer wheels for a few years.

Part #6781847-02 is printed on it, which from Googling, I understand is the same as 36236781847 (last 7 digits of it). It says it's 433 MHz.

US $110 OBO, including shipping.
