I keep waiting for the manufacturers of these systems to start using the same technology modern cars use and stop using batteries.
Kinda doubt we will ever see that on TT's and FW's. Manufactures still don't want to switch to disc brakes let alone computer controlled ABS.
"Indirect TPMS works with your car’s Antilock Braking System’s (ABS) wheel speed sensors. If a tire’s pressure is low, it will roll at a different wheel speed than the other tires. This information is detected by your car’s computer system, which triggers the dashboard indicator light."
