Your Audi comes with a variety of systems that play unique roles in the overall performance of the vehicle. One of such vital system is the evaporative control system (simply known as EVAP) and its purpose is to contain gasoline fumes, so they are not released into the environment. It’s your Audi’s way of controlling pollution.
Driving with a leaking evaporative system puts you and your passengers in danger of inhaling harmful fumes. It will likely cause the check engine light to come “on”, with the most common codes being:
- P0442 - Evaporative Emission System (EVAP) Small Leak Detected
- P0455 - Evaporative Emission System (EVAP) Large Leak Detected
- P0446 - Evaporative Emission System (EVAP) Vent System Performance
If your vehicle has hard time starting after you fill the gas tank, it could also indicate potential EVAP problem.
At Toole’s Garage in San Carlos we can diagnose any EVAP issues your Audi may experience. Typically we will first read the fault codes as they often will give an indication which part of the EVAP system is at fault, and also how sever the problem might be. Next we will review database that contains information about fault codes and related EVAP issues. Depending on the codes we find and which part of the system we suspect, we will connect professional scan tool or a smoke machine ( yes, it literally blows smoke into the EVAP system - location of the escaping smoke is where the EVAP leak occurs). Once we know the location of the leak, or which component failed, we can make repairs.
