When 1 or 2 glow plugs are are feeling poorly, the light can go off. If it has been more than 1 year (or 2) since they were changed, I would purchase a set to have on hand for the big day. Check your fuses too though and wiggle your wires to make sure your nuts are tight.

We have a 1984 300D. Glow plug light is now not coming on. Car does start right up. Where do I start in trying to fiqure this out.

thanks, Nick




I know it's hard to bend over with tight nuts and all that, but you should check the plugs for continuity at least.  Pull the plug on the relay box and check from each of the internal contacts to ground.  Keep in mind that there are 6 contacts and only 5 glow plugs.  Or. if you can manage to bend over far enough, check the continuity between the electrical connection on the glow  plugs and ground - with the plug in the relay box disconnected.  If you have continuity, the plugs should be working.
