I find that with my '98 E300 DT there is slightly longer crank times even on a hot shutdown restart if I don't wait for the glow plug light to go out than if I wait the extra second or two for it to glow. I learned to drive on a '74 240D and with that car you only needed to pre-glow when it was cold, ie the first start of the day. In that car if the engine was even lukewarm it would kick right over without a millisecond of glow. But the OM606 seems to appreciate a second or two of pre-glow even when it is hot so I do it. It may be the newer style of pre-chamber that relies on the plugs more than the heat stored up in the head, but whatever the reason the car seems to like it better that way.

I guess I feel, like another responder, that GPs are cheaper and easier to replace than a starter so if I can cut a second or two of cranking off the starter every time I hot start it I might extend its life a little in the long run...plus I like the sound of it just kicking over and starting with less than one revolution of the engine rather than listening to rururur.
