What does the glow plug light indicate on my Mercedes A-Class?
Years 2018-2024

Answer

If the flashing glow plug light on your Mercedes A-Class comes on, it simply indicates that they are scanning and that the engine does not start running until the preheating cycle is completed. If, on the other hand, the glow plug warning light flashes for 60 seconds after starting or while driving, the glow plugs are worn or dirty and should be checked.
