What year is your car? Assuming that it is one of the older versions, make up a short jumper out of #12 wire with alligator clips on the end and jump each of the terminals, in turn, of the glow plugs on the engine block until the light comes on. When the light comes on, the jumped glow plug is the bad one and must be replaced, although it can be argued that it is smart to do all of them at the same time.
Keep the jumper with you to get you going if one fails again.
