So I finished up ordering 5 of these :
Ebay TPMS (4)
There definitely seemed to be some sort of specification update in 2015. The critical factor for me was for the sensor to be able to transmit @ 433mhz in order to communicate with the OEM "TPMS Brain" in the car.
Spoke to one of my trusted VW Indepndant Tech's today, and he agreed with my logic. His pricing was similar to my find on eBay, then he would've added a handling markup charge. So...for the sake of about $250.00 I'm gonna give these a go. if they don't work, they'll be 'dead weight' for the next 70 - 80k klms use I get out of these rims and tyres (Pirelli Scorpion ATR 255/55/R19)
*fingers crossed
