1999 Audi A6 OBD2 Fault Codes P0441 and P0455 - Check Engine Light at 92,000 Miles
Hello, I've been experiencing a check engine light on my 1999 Audi A6 with 92,000 miles. After replacing the gas cap, the issue persists. The vehicle consistently displays fault codes P0441 and P0455 every two days. These codes are related to the evaporative emission control system. I'm seeking advice on possible causes and solutions for these recurring issues.
Fault code P0441 refers to a malfunction in the evaporative emissions system, specifically indicating an issue with the purge valve or its control circuit. For detailed information, see: http://www.obd-codes.com/p0441. Fault code P0455 indicates a large leak in the evaporative emission system, often due to a faulty gas cap, hose, or vapor canister.
