DTC's 120408, 164040, 164041

When I received this vehicle, it was not running. The diagnosis given to the owner was a catastrophic turbo failure. Upon inspection the only problem that was obvious was the timing chain. I have replaced the timing chain. The timing chain was still intact; however, the guides were in pieces. After this repair I discovered the turbo had bad oil seals. I replaced the turbo. Now I get these faults.

DME (ECU) 120408 Charging pressure control: Switch off as consequence.
DME (ECU) 130304 VANOS, exhaust: control fault, camshaft jammed.
DME (ECU) 130104 VANOS, intake: control fault, camshaft jammed.
DME (ECU) 131501 VANOS, intake, cold start: not controllable
DME (ECU) 130401 VANOS, exhaust, cold start: not controllable

I have checked the movement of the VANOS pistons and actuators. All are good. I also replaced the turbo boost solenoid valve. The waste gate functions but I get no boost. I am using an Autel MaxiCOM MK808BT Pro scanner. I checked the cam position sensors, and they are wired correctly. I then looked at the DME and deleted adaptations and deleted adaptation for the variable camshaft timing control. I now receive the following codes:
DME (ECU) 120408 Charging pressure control: Switch off as consequence.
DME 9ECU0 164040 Intake camshaft: installation defective
DME 9ECU0 164041 Exhaust camshaft: installation defective
I electrically activated the VANOS control solenoids with the following results: On the intake camshaft the engine stumbled but did not shut off when the solenoid was actuated at idle, on the exhaust camshaft the engine stumbled and stalled at idle. What should I look at next?
