I checked the Huf site suggested here, but there is no listing for 2008 to 2010 models. Weird. Rock Auto lists 315 and 433 MHz for that year. Checking an online VW dealer with the VIN, it gives the part number 7PP907275F. Searching that on Ebay results in a few sensors for about $32 a set, like this listing: 4Pcs TPMS Tire Pressure Sensor For Touareg Phaeton Audi A4 A6 A8 Q7 433MHz | eBay Anyone try these low cost sensors?
