Hello there, the engine is running now, but my Lambdasensor (Wideband LSU 4.9 Type) records only an"36 RComp Invalid" error. Any Idea where this Comes from? Did I configure something wrong?

This indicates a potential sensor or wiring issue. The error refers to the calibration resistor contained within the sensor connector.

Do you still have the stock sensor connector on the sensor?

Measure resistance between pin 1 (APE) and Pin 5 (MES), the normal range is 30-300ohms.  I would also suggest you check this at the ECU end of the loom (ecu unplugged) as this will verify wiring is correct and all connections/crimps are sound.
