Mercedes-Benz CLA250 long start time with persistent check engine light after replacing camshaft sensors and adjustors on Mercedes-Benz CLA250

Some Mercedes-Benz CLA250 owners report experiencing long start times and a persistent check engine light even after replacing camshaft sensors and adjustors. These issues may arise from improper installation of the new components, which can lead to malfunctions. Additionally, owners are advised to scan for error codes using a diagnostic scanner to identify any underlying problems that may be triggering the check engine light. Faulty or loose wiring and connections related to the camshaft sensors and adjustors can also contribute to these symptoms. Furthermore, other components such as the crankshaft position sensor, fuel system, or ignition system may be involved, necessitating a comprehensive inspection. If the problems persist, it is recommended to consult a qualified mechanic or dealership experienced with Mercedes-Benz vehicles for a thorough diagnosis and resolution.
