Mercedes W108 SEL 350 D Jetronic injection trigger points replacement

Here i explain in few words the thing with the trigger points , one component of the D Jetronic injection sistem that fires the injectors , and if this thing is worn out , your car will run irregularly , no idle , sudden stop , etc because the timing of the injection is out of order

Thank you for the video. I have a doubt. When I put the motor in TDC, do the trigger points automatically adjust?

What is the function of this part called trigger points? How do you test them?
