Glow plug warning light on Mercedes B-Class, what does it mean?
Years 2011-2019

Answer

If on your Mercedes B-Class you have noticed that the glow plugs come on when the engine is started and then goes out, you should know that everything is normal. This brief appearance only indicates that the glow plugs have been activated to allow the engine to start. If, on the other hand, the lights remain on steady then there is a fault in the system.
