Focus Mk2 Tdci Glow Plug Indicator

[mark 9104]

does the glow plug indicator come on every time you start the car or does the outside ambient temperature effect its use

If you mean the little yellow coil, yes it does. How long it stays on is affected by outside temperature, but it shouldnt stay on longer than a second or two. And you should only start the car once it goes out :).
