P3 V3 OBD2 Vent Gauge for Audi TT/TTS/TTRS 8S (2015+) OEM-Style Digital Boost, Plug-and-Play Multi-Function Scan Gauge & Code Reader

P3 V3 vent-mounted digital performance display for Audi TT, TTS and TTRS 8S 2015+

Transform your Mk3 TT cockpit with the discreet P3 V3 vent display that blends in like factory equipment yet delivers serious live data. This clever unit slots into the air vent for a clean, OEM-style finish, pulling real-time information from the diagnostic socket so you can track turbo pressure, engine vitals, and performance metrics without cluttering your cabin. It looks stock, reads fast, and keeps full air flow through the vent.

We run this kit on our own cars and customers love it. The fit and finish are spot on, the screen is crisp, and the readings are consistently accurate. If you want a stealth install with proper functionality on the 8S platform, this is the one to have.
