P3Cars V3 Vent-Mounted Digital Display for Volkswagen Jetta 2011 to 2018

Transform your Mk6 Jetta cabin with a tidy, factory-style data display that lives inside the air vent and still lets the ventilation work as normal. The P3Cars V3 is a stealth performance monitor that plugs into the diagnostic port to show live engine info, turbo pressure, and essential parameters, plus it can read and clear fault codes. Ideal for daily use, spirited driving and track days, it gives you the numbers you want without bulky pillar pods or a cluttered dashboard.

We run this unit on our own cars and customer builds. The responsiveness, accuracy and OEM look are superb, and feedback from Jetta owners has been consistently positive.
