Ok. Purchased a new cps today. Didn't sees to bad a job. And although it was riddiculously expensive it's another thing to rule out. But now it seems like I've ran into this problem m103 Crank Position sensor removal and replacement - Mercedes-Benz Forum
Got the bolt out, and the sensor seems to be moving, but it doesn't come up. As the sun was setting and it is cold (3-4 degrees) I quit for today. And then also either i teared another wire while jiggling around or at least I found a loose wire.
All in all a bad merc day here in Oslo. ...to be continued...
