Mercedes-Benz SL55 AMG coolant warning message persists after coolant addition on Mercedes-Benz SL55 AMG

Some Mercedes-Benz SL55 AMG owners report experiencing persistent coolant warning messages even after adding coolant. These issues may arise from low coolant levels, which should be topped off with the recommended coolant type. Additionally, some owners find that resetting the coolant light is necessary after addressing any coolant issues, requiring them to locate and access the coolant reservoir. A common cause of the warning message is a faulty coolant level sensor, which may fail to accurately detect the coolant level and communicate this to the vehicle's computer system. It is essential for owners to address the coolant warning message promptly, as neglecting it can lead to potential engine damage if the coolant level remains low.
