You can eliminate the defective coil question by swapping all 3 coil packs from 1,2,3 to 4,5,6.
Often, crankshaft / camshaft sensor being defective does not store any error codes.
Ok, I will replace those 3 coils with new ones - less work
and let You know if it helped.
I will also read the error codes after replacement and post them here
Thanks a lot for all information's.
