P3 Gauge - VW Polo / GTI / TDI

P3 Gauge – VW Polo / GTI / TDI (MK5)

Custom built multi-function digital boost gauge and more for the Volkswagen Polo (2009-2017), including Polo Trendline, Comfortline, Highline, Polo GTI 1.4 TSI and 1.8 TSI, Polo R WRC 2.0 TSI, as well as Polo TDI 1.2, 1.4, and 1.6 models.

Form and Function

Every P3 Gauge is built just for your car. It fits perfectly—like it was born there.

Stealthy. Stylish. Smart.

In one sleek display you get real-time access to everything that matters—boost pressure, engine temperatures, performance timers, diagnostic reading/clearing, and more. All from the included diagnostics port connection or optional add-on sensors.

It’s easy to install, simple to use, and made to last.

Every unit is built to order, hand-assembled, and developed entirely in-house—not by a huge corporation but by a small team who loves cars as much as you do.

Gauge Modes / Readings

We designed the P3 Gauge to read the most important data from your specific vehicle for easy plug-and-play installation. You’ll get everything you need with a single OBD port connection to be up and running in minutes. If you wish to add additional sensors, or not use OBD at all, advanced tuners can use analog inputs or even run in analog-only mode.

OBD Port Data (CANbus Input)

• Boost Pressure
• Coolant Temperature
• Air/Fuel Ratio (AFR or Lambda)
• Vehicle Speed (Calibrated or Raw)
• Intake Air Temperature (IAT)
• Throttle Angle
• Ignition Timing
• Engine RPM (with programmable shift light)
• Exhaust Gas Temperature (EGT)
• Battery Voltage
• Acceleration Timers (0–60, 0–100, 60–130)
• Braking Timers (60–0, 100–0)
• Read & Clear Diagnostic Trouble Codes (DTCs)
