Thanks. From what I can guess, all 2011 models Golf should have the rubber valve stems and ABS sensor based TPMS. As shown in this article,
http://www.myturbodiesel.com/1000q/a...g-light-vw.htm, the simpler system isn't as accurate but the sensors system is having some setting problems in Golf and the sensors need replacement after 5-8 years due to the sealed battery. It's legal to drive with dead batteries and bad sensors once the car leaves the dealer lot but I wouldn't. Your system is reset by pressing the reset button and you don't need another set of sensors for winter tires and such.
