Vehicles 06.99 and up

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

These vehicles include the latest EVAP system generation with an On board Refueling Vapor Recovery (ORVR) system. The ORVR system is a type of Evaporative Emission (EVAP) control system required for new vehicles. When refueling, vapor in the fuel tank is displaced by incoming fuel, and this fuel vapor, which used to be vented to the atmosphere, is now recovered. The ORVR system requires a large EVAP canister, large vent lines and a new breather valve.
