I think it's a legal requirement, someone should know, here in the UK we still use the "Pressure differential" method, this is the best way IMO as you can change out the wheels and just reset the system, no need of expensive wheel sensors to be bought for all wheels. I have had these sensors go wrong in Audi's and they ain't cheap.
