300SD Preglow indicator light failure
 

does it mean anything if the preglow light on the instument cluster does not light up at all? it stopped last night. have had a dozen successful starts.

thanks.

May just be a blown lamp, GP are still working.

Could also be a blown fuse, check on the GP relay (left fender under the cover) for a crack.

Could be more than one GP out too, although usually you will get it flashing at you after you start when a GP is out and hard starting.
