Glow Plug LIght is Flashing

4863 Views 10 Replies 5 Participants Last post by  MBeige
I just encountered this problem today and it has never happened before. When I turn the car on and the engine is running the glow plug light will flash for about 30 or so seconds. Does this mean they need replacing? Or did a cable come off? Please help. I dont wanna drive it if its unsafe like this.
