"Corrupt" = change a bit to its opposite value?
Yes.

Can it be broken down into several smaller transactions, so that in total there are 7 bits (or less)?
If the answer to all questions is "yes", then all four bits should be transmitted one by one, and Alex can change the value of the bits to the opposite and read them. Although, on the other hand, it is not a fact that the Germans will necessarily corrupt this bit; the wording says that they "may"...
Everything is transmitted at once. Any one of the seven bits may be corrupted, or none of them may be corrupted. Let's assume that the message is contained in the first four bits, and we need to determine whether one of them was corrupted or not, and if so, which one.
