Pls help, idle shakes on C250 CDI 2012
Guys, good day!
im writing to see if anyone had the same problem as me.
so the problem is i get ver very little barely noticablr periodic shakes (like misfires) on idle. It is more notixable in drive when stationary, but also does some in P. These happen sometimes.
i underatand it may be injectors, however, my car has a perfectly smooth and efficient accelartion let alone the smoking. Starts in a quarter second also.
what is you opinion guys? Any thought would be appreciated.
p.s. i phoned previous owner and he said he tried to
diagnose these however the service ppl told him
this has to do with oil pressure in the gearbox and theres basically nothing u can so abt it.

Anyways, i will post an update after diagnostics i had.
so i went in for checks, and to make it clear car made these shakes only on cold, until like 60C, so what they told me is that no fault codes, car is ideal, all parameters from injector plugs are perfect as well as fuel pump. The mech suggested it is some kind of valve within the pump, some kind of a regulator, i didnt write it down, he said not dangerous or anything, if i wanna diagnose more ill have to take it in for the night so that they can cold start it.
