Why did the glow plug light come on in the Mercedes A-Class?
Years 2018-2024

Answer

In the Mercedes A-Class, the glow plug light is represented by a double spiral and its lighting indicates the presence of a malfunction. It can be accompanied by other signals or by abnormal engine behavior, mainly during the starting phase. The problem can often be solved by directly replacing the faulty glow plug, an operation for a few tens of Euros.
