Mercedes CLA Diesel Start Stop Problem

Start-stop issues are annoying You mention an error code Do you know the code That would help A discharged battery is a suspect, especially with idle stop Does the starter motor crank strongly on restart, or weakly If weak, the battery is more likely

I don't have the error code The starter motor seems normal If the starter motor works as expected, could the battery still be the problem

Even with a normal starter motor, the battery can still cause problems Start-stop vehicles are sensitive to voltage fluctuations The system might detect a drop and disable idle stop I suggest a professional battery test at a workshop

Thanks for the advice I had the battery tested at a workshop It was discharged and defective Replacing it fixed the start-stop system The repair cost 290€
