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!

one or more of your plugs are not working __________________________________________ Never argue with an idiot. They'll drag you down to their level and beat you with experience.
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:
- Glow plug(s)
- Glow plug relay
- Fuse
- Poor ground strap.
