That is true. But on a '83 240D, it has nothing to do with starting the engine.

If the glow lamp is not illuminating at all, the issue is not temperature. The problem is that one or more of the glow plugs are inoperative. Or the lamp is burned out. Or the timer unit is malfunctioning.
If you glow the plugs and do
not attempt a start, how long does the relay remain closed? You should be able to hear it "clunk" when it opens.
