The glow plug light on my 1977 240D has failed to come on two times now. Once, two weeks ago and this past Friday. On Friday, I turned the key three times with a one minute space and no light. Tried cranking it the first time in case it was the bulb--no go. Waited five minutes and it the light came on and the car started.

Any ideas--Should I replace the glow plugs or would that just be throwing money at the problem?

By the way. Drove the car from Austin, TX to Orlando, Fl leaving last Wednesday night. 22 hours, 1187 miles, 27.85 MPG

Thanks
