The status of CP violations in charm sector is still unsettled. According to SM, the predicted asymmetries are small, but often affected by large uncertainties due to long-distance effects. However, it is possible to build observables which SM predicts to be CP-conserving, so that any measured asymmetry is undoubtedly a sign of New Physics.  We present the analysis of CP-asymmetries of singly Cabibbo-suppressed decays $D^{+} \to \pi^{+} \pi^{0}$, using the final dataset collected by BABAR. We discuss the sensitivity to CP-violating phases, and the correspondent New Physics constraints.
