Installing a Turbo Pressure Gauge

Model: Audi A4 B6 - Years 2000-2004
Part: Accessory kit

In the 1980s and 1990s, the turbo pressure gauge was a common accessory in the instrument cluster of many turbocharged cars, but it has gradually disappeared, replaced by aftermarket kits that include the gauge and the necessary installation set. Essentially, you need to tap into one of the boost hoses, insert a T-fitting from which to run a hose into the cabin, and connect the gauge, which will also need to be powered with 12 volts (it is recommended to install it above the instrument cluster, near the windshield pillar).
