Description

The P3 V3 Gauge is a custom-built, multi-function digital gauge designed specifically for the C7 generation (2011-2018) Audi A6, S6, A7, S7, and RS7 models. It integrates seamlessly into your vehicle's vent, maintaining the original airflow and providing an OEM+ look. Installation is straightforward with a plug-and-play connection to your OBD2 port. For those who wish to keep their OBD2 port free, a hard-wire harness kit is also available. The gauge is engineered to withstand extreme temperatures, functioning reliably from -94°F to hundreds of degrees Fahrenheit, far beyond typical in-car conditions. This versatile gauge offers a wide array of readouts, including Boost (via OBD2 or optional analog sensor), Coolant Temperature, Air/Fuel Ratio (AFR or Lambda), Vehicle Speed (with calibration options), Intake Air Temperature, Throttle Angle, Ignition Timing, Engine RPM, Exhaust Gas Temperature, and Battery Voltage. It also features a programmable shift light, acceleration timers (0-60mph, 0-100mph, 60-130mph), and braking timers (60-0mph, 100-0mph). Additionally, the P3 V3 Gauge allows you to read and clear diagnostic trouble codes (DTCs) on the fly, offering enhanced control and diagnostics. Optional add-ons are available to further enhance the gauge's functionality, including an analog boost sensor, boost tubing kit, an ESVA for ethanol content and fuel temperature reading, a trim removal kit for easier installation, and an OBD2 splitter. The gauge is configurable to display units in either Imperial or Metric measurements and allows for individual PID removal from the display if desired.
