I have a used set of 4 TPMS. These are OEM GENUINE Parts (not aftermarket or OE supplier), Part #36-23-6-781-847. These are very expensive new, easily over 2x my asking price. They include the stems and caps. I will add pictures tonight. I believe they fit 07-10 3 series, but you are responsible to know fitment, part number is provided above.
$150 shipped in the U.S. Paypal only please. First to Paypal me gets them. No dibs etc. These tend to go fast.
