P3 analogue display for Audi B9 A4, S4, A5, S5, RS5 2016 onwards

Elevate your cockpit with a factory-look performance monitor that shows real-time manifold pressure and vacuum along with extra sensor data, all in a clean OEM-style package. The P3 analogue display is the enthusiast’s choice for Audi B9 drivers who want discreet, accurate readings without bulky add-ons. We use this kit ourselves at MJ Modifications and our customers love the clarity, reliability and stock-style integration.

Why this performance monitor stands out

• Precise turbo pressure and vacuum tracking that helps protect engines on mapped, remapped and hybrid turbo builds as well as standard cars.
• Two configurable 0 to 5 volt channels to view additional senders such as oil pressure, fuel pressure, ethanol content, coolant temperature or intake air temperature. Sensors not included.
• Battery voltage readout built in for quick electrical health checks.
• Subtle, stock-appearance display that blends into the cabin for a stealth, OE feel.
• Proven by us and our customers with consistent, repeatable readings and an easy-to-use interface.

Inputs and wiring

• Dedicated boost input using the included sensor lead (yellow / purple / black). A take-off for the manifold line is required, not included.
• Analog input 1 (brown wire) accepts any linear 0 to 5 V sensor output.
• Analog input 2 (blue wire) accepts any linear 0 to 5 V sensor output.
• Voltage monitoring via the power and ground connections (red wire / black wire).

Night-friendly dimming

For automatic brightness reduction at night, connect the green wire to a lighting circuit that is powered only when the headlamps are on, then enable the function in the configuration menu. Enjoy a comfortable, glare-free display after dark.

Perfect for tuned B9 platforms

Whether you run Stage 1, Stage 2 or a hybrid turbo setup, this unit gives you the confidence to push on while keeping a close eye on key parameters. Ideal for daily-driven cars and track builds seeking a discreet, OEM-style solution.
