My 1987 190 D diesel motor has a problem when I shuttthe key off
it runs and shakes a bit for 2 seconds does it need to be timing
can someone tell me on this forum

 

You already have ForceInduction's reply. The reason I add this is because old cars usually do it, plus you probably heard the term dieseling applying to this sound, typical of diesel engines, when occurring on any Otto cycle engine also upon shut off.

 

so how can I verify that is where it is leaking the vacuum
is it a line or other thing to check I send a pix of my motor
can someone show me where and what vacuum
and also my unlocking doors are not working since last year is it also vacumm or leak where can i check that thanks
