[SOLVED] E280 CDI Starting problem / crank voltage drop

Good day all,
My car started 3month ago giving me problem when starting the car.
here is the video on youtube

the car will crank but stop as if something was broken inside the engine , well after servicing the car the problem went away .
But i traveled for 10 days and when i came back the battery was dead i couldn't event unlock the car. We jump started then few day after the starting issue came back . right now i have 7000km before the next service. then i started look for electricity problem.
- have changed the starter first
- then the two batteries.
- changed the camshaft position sensor which was showing on the diag.
- yesterday i removed the roof to disconnect the cargo cover motor (diag was saying that there was short circuit.)
- alternator is charging correctly .
- once the car start i can switched off and on as much as i want with no issue .

I would be grateful if you guys would help me

i'm out of ideas .

Regards

Here is an update this morning the car started correctly around 9 am .
here is a video made a 1 pm .

and just after that i switched and started again .

Engine runs fine . no check light no smoke no particular noise .

UPDATE 3 :
The mechanic guy removed yesterday the engine belt tested the alternator pulley , water pump ,A/C compressor, power steering pump , nothing .

But this morning when cranking it feels like the engine will have one revolution hit something turn again hit it . and it only does that when the oil is back down .
Just right after the car says "engine oil sensor visit workshop" .
maybe one part of that sensor or something else is broken in the engine causing this problem . But i guess if it was a mechanical part we would have hear a noise after the engine start .the problem is definitely not electrical.
