Go to this page:
15 Electrical System Engine (Preglow) - OM617
and select 15-510. Go to section D and read how to check the glow plugs.

The headlight fuse has nothing to do with the glowers. Check the plugs and wires for damage. Be sure to use the correct fuse.

glow plug light

The glow plug light did not illuminate in my car--had to time the warm up for about 1.5 minutes and then she would start but still difficult. Just had the glow plug thermostat time switch replaced and now the light illuminates and she starts right up. I know this part is hard to come by but saw one on ebay this morning.
