Sorry, I know your first language is not English but that does not make sense, what are you trying to do? Do you want to take your engine to the power of a CDNC?

I want to replace the old broken engine with a new and a new is that CDNC.

There are no physical differences between a CDNB and a CNDC, the power difference is provided by the programming of the ECU so you do not need to make any changes. If you bought a brand new engine from Audi, the part number for the CDNB and CDNC is the same.
