Evaporative Emission System: Notes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi A4 Quattro, 2014 Audi A4 Quattro, and 2013 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
The evaporative emission system has been designed to minimize the release of hydrocarbons from the fuel system into the atmosphere. The evaporative emission system components all work together with the ECM to prevent fuel vapor from escaping and route it to the intake manifold to be burned during normal combustion.
The leak detection system checks the integrity of the evaporative emission system by pressurizing the system.
- There are 3 different types of evaporative emission systems used. These systems are explained below.
- Refer to LEAK DETECTION PUMP (LDP) EVAP SYSTEM
- Refer to TANK LEAK DIAGNOSTIC MODULE (DM - TL) EVAP SYSTEM
- Refer to NATURAL VACUUM LEAK DETECTION (NVLD) EVAP SYSTEM
- Refer to EVAP SYSTEM, CHECKING FOR LEAKS
