the spanish phrases above seem to come from an user's manual and they are written in a very deficient way and are too ambiguous. Cherry translation is a very good attempt but have the problem that is an interpretation, which in a technical translation it should be avoided. the last phrase is totally absurd. require the services of a good technical translator who is familiar with these products. or, having a closer look, the text may be a letter from some distributor or alike which seems to want to be clear in exposition because expects lack of knowledge of the langauge and thus complicating the correct exposition of ideas. here only the logics of those in the "bussiness" is of help. as a procedure has a limited field of possiblities, maybe they understand what they are meaning.

Wie geht es dir? No comprendo por qué esa pieza no lleva el cableado 5P1971161A. No nos han dicho que lo eliminemos (no hay que eliminarlo) Siempre que esa pieza lleva el módulo de cableado 5P1970139, como en este caso, debe llevar también el cableado 5P1971161A.

Hallo Paddelboot, Ich erkläre es dir auf Deutsch. "Ich verstehe nicht warum dieses Stück das Kabel 5P1971161A nicht trägt. Wir haben daran keine Veränderungen vorgenommen , um es zu beseitigen. Wann immer das Modul des Kabels 5P1970139 existiert wie in diesem Fall, muss man es besorgen."
