After the broken DISA and and a new valve i put everything togheter again. i had some problems with the KGE, the hoses wont snap in, after hours i made it but i think when i installed the intake manifold it could have come off again.
After assembly i delete all errors and start my car, it started, but went out as the petrol line slipped off from the ijection rail. i hadn't closed the clutch lock from it. after i reconnected and vented the line i wanted to start the car again, but it wont to start. starter is working, several tries later i read out the error log.

2A9A Nockenwellensensor Einlass, Signal

i changed magnetic valves, camshaft sensors, but the error comes back and the car wont start. every 4-5 start tries, the car almost starts... i have no more idea, maybe crankshaft sensor? skipped chain?

Did you end up doing any work to the head? I'd wonder if the engine was timed correctly if you indeed did remove the head and such. Have you checked it there are any fuses related to the camshaft position sensor wiring? I think it's fuse F02

i gave the head to an engine builder to renew the valve seat, cause the valve has not sealed anymore + new valve. after assembly i used a timing chain kit for timing and checked it after some rotations, everything looked fine.
i have not checked any fuses, i'll do that first thing tomorrow.

Could A0B4 indicate the starter? no problems previously.

I'm not sure what that code means but I have gotten it before when I get a crank but no start situation. Last time that happened I had blown fuse F11 which runs the crankshaft position sensor and will throw codes for disa valves and the evap vent valve aswell as oil level sensor

Cant find fuses for crankshaft sensor.
My N52 2005 non turbo version has only a few fuses in the e-box.

i just did a compression test, i dont think its worse -> only 5-7 bar on each cylinder do not understand what happened.

i think i will check the timing chain tomorrow.
the engine run first, maybe the possibilty the chain was skipped, cant think of anything else.

Why don't you take off the intake manifold and recheck everything again. You crankshaft position sensor wire could have possibly come off or broke as if the wiring is not routed right, it can cause too much tension and come off. I've actually had that happen to me. And it's not just that wire, the wire to the power distribution box to the connector mounted on the manifold and come off too. I think those two problems might be it especially if you're saying some hoses could have come loose when reinstalling the manifold. Also remember there is a sensor plug that often gets overlooked to reconnect down there as well next to another hose by the distribution box area.

I'll check it out tomorrow. Which sensor plug do you mean in the distribution box area?
On intake manifold system i checked the wirings: adjuster 1&2, angle connector, pressure sensor and throttle.

It’s a square connector with a push in metal clip. Not sure how to post pics on here anymore.

can you find it over bmw etk?

It's on the bottom of the bracket on the opposite side of that bottom hose connector. Most people tend to forget to reconnect that one.

My best guess is either that is not connected, or the crankshaft position sensor wiring being pulled out or broken/ripped. Possibly a combination of both.

i think you talk about tank ventilation. "unfortunately" everything is fine there.
it also doesn't solve the problem with poor compression. ~70psi (5bar)

i checked the timing. ex camshaft is okay, but inlet camshaft is twisted by about 5°...
i bought the camshaft adjusters used on ebay. can it be that it is broken, may it be responsible for it?

i checked the timing 2 times. the torque was also right.

Update:

A new camshaft adjuster brought the solution. everything rebuilt and adjusted again and the engine started
