Glow plug liight?

The glow plug preheat light on my '92 300D recently stopped lighting during what should have been preheat but comes on *after* the engine starts and
glows for about 15 seconds. Any words of wisdom?
Thanks!

That means you got problem on your glow plug system. Do a resistance check on all your glow plugs. Make sure the fuse strip is good and has power...
It can be any conbination of:
1. Glow plug(s) 2. Glow plug relay 3. Fuse 4. Poor ground strap.
