Show original supplier description
The P3 V3 OBD2 Multi-Gauge is a custom-built digital display designed specifically for the 8V generation (2013-2020) Audi A3, S3, and RS3, including 1.0 TFSI, 1.4 TFSI, 2.0 TFSI, 1.6 TDI, 2.0 TDI, and 2.5 TFSI quattro models. By integrating directly with the vehicle's CANbus system, it delivers real-time monitoring of essential metrics such as boost pressure, coolant temperature, air/fuel ratio, exhaust gas temperature (EGT), throttle angle, and battery voltage. The unit also includes built-in performance timers for acceleration and braking, as well as the ability to read and clear diagnostic trouble codes (DTCs). Advanced users looking to expand functionality can utilize three additional 0-5V universal analog inputs for auxiliary sensors, such as an analog boost sensor for forced induction setups, or a dedicated dimmer voltage input to sync the display's brightness with interior cabin lighting.
