Hei so i have swapped out the engine on my w212 e220cdi.
I got a complete engine from the scrapyard.
Installed the engine and used my ecu crd2.16 the car wont start.
So when i look at the ecu that followed the engine from the scrap yard it is crd2.15.
Is there a diffrent pinout on does two solenids? crd2.15 vs crd2.16

 

I believe a person in the diesel section just went thru something similar replacing his engine. May wanna hop over there as you will get more diesel knowledgeable folks taking a look at this issue.

I cant answer your question but will add there are a ton of different om651 versions out there. Using your ECU with the donor engine will take some programming of the ecu or swapping some of your other parts back over as well. In your case benz ninja may be a beneficial help as well.

 

ok thx will check that out
