Most probably u have a immo problem. Start by checking fuel at injectors, and then folow backwards.
I've seen so many hard start related issues, no one can guess correctly.
Just troubleshoot it.
It looks like some of those even have problems with bad battery and starter... who knows what is going on!!!

Of course it does, limited of course but it does.

Did you ever figure this out? I'm having the same problem with my 602...starts right away first thing in the morning, but subsequent starts take 5-10 seconds. Glow plugs are new and the relay checks out. Injectors are rebuilt with new Monark nozzles and balanced. Battery is brand new. The DV seals look to be leaking slightly - this will be fixed shortly with installation of a new Dieselmeken pump - but if there's a significant fuel leak, I don't get why it would start fine after sitting overnight. Or why it wouldn't act up while driving. About the only thing I can come up with is possibly a bad starter that is getting heat soaked, maybe? But I don't want to just start throwing parts at the problem...
By the way, I don't think it has to do with poor compression - again, the car starts wonderfully in the mornings, and there is no smoke, loss of power, rough running, etc.

I have the same problem with my 605. When cold starts right up,even below freezing, below 70 *C coolant temp still starts relatively easily, at 90*C it takes at least 3-4 seconds cranking. No diff if i wait for glow plugs or not. I suspect worn injection pump elements. I had a similar problem with my tractor, but it had a rotary DPA pump. Wouldn't start at all when warm. Once it cools down it started ok. It was a bad hydraulic head in the pump

With worn rotary head pumps it's the main problem that it needs long cranking when hot. Pour a bucket of cold water on pump and it starts right away.
With mercedes pumps it's not really a problem. First look at pump timing.
