Three weeks ago, the check engine light in my 2014 Audi Q3 turned on. After researching online on several fault codes website, I discovered that the fault code indicates an issue with the purge flow in the evaporative emission control (EVAP) system. However, I'm having trouble understanding the exact process for diagnosing this problem, and when I took my car to a mechanic, I wasn't sure if they were being honest with me. Could you please help me understand how to diagnose this issue correctly?
