What the Glow Plug Light (Diesel) Means on a Ferrari F8 Tributo
On a diesel Ferrari F8 Tributo, the coiled glow-plug light is normal at start-up: it shows the glow plugs are pre-heating the cylinders. You wait for it to go out before cranking. If it flashes after warm-up, it signals a glow-plug or engine management fault.
How Urgent Is the Glow Plug Light (Diesel)?
