Finite add(N)-resolution

Let $A$ be a local selfinjective algebra with indecomposable module $M$. Let $N=A \oplus M$. Is there an indecomposable module U not in add(N), having finite $add(N)$-resolution for some choice of $A$ and $M$? This is not possible for the following examples:

-A=K[x]/(x^n) for arbitary M

-A arbitrary and M simple.
