Which frequency should I use when the vehicles model year has options for both 315MHz and 433MHz?


Some vehicle manufacturers use both 315MHz and 433/434MHz sensors in the same model year. For example, Audi used either 315MHz or 433MHz frequency sensors on their 2005 and 2007 model year A6 vehicles. Select one frequency and attempt to activate. If the sensor fails to activate, choose the other frequency and attempt sensor activation.
