I’m by no mean an expert but am impressed you didn’t use any sentence enhancing words during that process. Thanks for including the visual. It says it all.
If it were a gasser I’d say crank position sensor. Since it’s common rail diesel injection that also comes back to fuel pump. Able to pull any codes off the beasty.

1. Read codes
2. Follow the trail
3. No codes? As de pug say, CPS OR
Fuel pressure ie pump. But you say fuel is not an issue?
How and why?

do you have access to a scan tool?
I would check the mpa of the pump from the suction control valve solenoid.
you should see 30 to 35mpa at idle or cranking general speaking
if you are getting a reading of 25mpa the car may start
if it is less than 25mpa it properly won't start
since it is still reading a value of example 20mpa it won't throw a code it just thinks there not enough fuel pressure to start the car and keep it running
also a scv has only 2 bolt and cost is only a small amount you will properly have to goto to a diesel specialist to get the part cause mb will only sell the pump complete
you may have noticed more inconsistency/or rougher idle for a few months or it cranking longer to start

Leave a couple of sandwiches and bitters in the boot after the car is dropped off. Call from home and tell the tech to enjoy it since you forgot it ![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
