Hi, I’m Patrik from Sweden and new to this forum.
I got a 2006 w169 A150 automatik for free, and after a few month of headace I see why it was free.
The car had a faulty starter from the beginning and it was swapped and worked for a while, but then crapped out and did not start anymore.
It’s a No crank No start situation.
The former owner macgyvered a startbutton so now it’s possible to get it started, but I have to push the service button on the gear selector to be able to move the selector to drive.
I have a LOT of faultcodes that says that the CAN signal is interrupted.
I have checked all fuses and relays but all was good.
Does anyone have o schematic of component locations (CAN connections etc) or even better, a solution for my problem.
I will include some photos of my faulcodes.

BTW the 006f-001 variant coding was active before the starter was swapped out.

 

Just wanted to update, the fault was easier than expected.
it was the blue relay at the SAM module.
Simple as that.
