Care to explain why the MB FSM would say that if it were not true ?

after the 86 model, the GP relay got changed to a model that will glow up to 3 minutes. before that, you only got about 40 seconds.

My drivers:
1987 190D 2.5Turbo
1987 560SL convertible
1987 190D 2.5-5SPEED!!!

1987 300TD
2005 Dodge Sprinter 2500 158"WB
1994GMC 2500 6.5Turbo truck... I had to put the ladder somewhere!

Maybe it was written by someone who is not very well versed in the engineering of the vehicle?

Maybe, just maybe, we know a bit more about the vehicle than the person who wrote that manual..........

Why does the manual state to wait until the glow plug light goes out and then start the engine? Don't we already know that this statement is false at any temperature less than 32°F.?

While you might be a champion of the written word in the FSM, don't take every last word as gospel.

That is the Minimum time before starting the engine..( regularly trying to start over the life of the engine before the light went out would place extra strain on the starter.)

Then they put the other information in so you could use it in extreme situations where trying it right after the light goes out does not work.

Does the manual state "that is the minimum time before starting the engine"?? I don't believe that it does. We, therefore, have gleaned additional info regarding the start procedure for these engines.......info that is not in the manual.

In similar manner to the 35 second glow timer on the relay........also not mentioned in the manual.........the FSM is simply a very good guide........it's nowhere near perfect.
