Mercedes-Benz CLK55 AMG engine won't turn over, possible starter relay or solenoid issue on Mercedes-Benz CLK55 AMG

Some Mercedes-Benz CLK55 AMG owners report experiencing issues with the engine not turning over, often related to the starter relay or solenoid. Commonly reported problems include low battery voltage, which can manifest as a clicking noise when attempting to start the engine. Additionally, a defective starter motor or relay may be indicated if the solenoid clicks but the starter fails to turn the engine. Wiring problems, potentially exacerbated by heat, can also lead to starter malfunctions. Owners have noted that a low battery with insufficient amps may lack the power needed to start the vehicle. Other potential causes reported include coils breaking down, faulty plugs, or fuel supply issues that prevent the engine from starting. To troubleshoot these issues, some owners suggest checking the starter relay for damage or corrosion, tapping the relay gently to see if it temporarily works, and listening for specific clicking sounds that can indicate the nature of the problem.
