Description
The P3 V3 Multi-Gauge transforms your factory air vent into a fully functional digital display that monitors your Audi’s performance in real time — all while maintaining a clean, OEM+ appearance.
Specifically designed for the B7-generation Audi A4, S4, and RS4, the P3 Gauge delivers instant access to vital engine data, boost pressure, temps, and diagnostics through your OBD2 port or optional analog sensors.
Form and Function
Every P3 Gauge is engineered specifically for your Audi model — stealthy, stylish, and smart, blending seamlessly with your factory interior.
Each gauge is hand-built to order, using an OEM vent housing for perfect fitment and an easy install that takes just minutes.
With advanced data monitoring, customizable inputs, and intuitive operation, the P3 V3 offers both form and function for drivers who expect the best from their Audi.
Gauge Modes / Readings
The P3 V3 Gauge is designed for effortless plug-and-play installation via your vehicle’s OBD2 port. It reads key data directly from the ECU for precise and reliable performance information.
