Re: [MBZ] E300D Glow Plug Relay Problem
In my experience, this is a bad relay or a #1 glow plug going bad. Could happen with new GP. Switch #1 and any other. I am betting it is a bad relay. It's possible to have loose contacts in the relay that cause it (or the light only) to come on when it should be off. Obviously, a loose wire from the keyswitch will do the same thing, but other things should be cycling too (does the radio antenna go up and down, for instance?). I had this happen on my Volvo TD -- if it happened at night, the alternator couldn't keep up and the battery would go dead. Pretty obvious, though, since the relay rattled when shaken!

It cycle normally in the when I start out to work, but 15 to 20 minutes into the ride it comes on and stays on for 30-40 seconds, longer than the morning glow. It does not come on again for the rest of the ride. It had been suggested that bad ignition may be cause this, if this was the case I would think it would come on multiple time through the ride as part of the interstate through Cincinnati are very rough. I may just replace the relay and see if that cures the problem. I just replaced all six glow plugs this past February.
