Hi !

I have a '99 E 300 Diesel. In the display near the steering wheel, the glow plug light still remains on even when the engine is on.

Do you know what could be the problem.

 

Hi MBlieber, Logan here. The problem there is the glow plug itself. One of the glow plugs must be busted, therefore the heating process of your engine takes longer. You might have a hard time running your car. Believe me, that already happened to me. If were you, I'll change the Mercedes Glow Plug as soon as possible. I don't like to prolong any damaged parts to prevent further damages. Just a friendly suggestion.
