We present a preliminary measurement of CP-violating asymmetries in fully reconstructed B 0 →D (*)± π ∓ and B 0 →D ± ρ ∓ decays in approximately 110 million Υ (4S) → BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. From a maximum likelihood fit to the time-dependent decay distributions we obtain for the CP-violating parameters: a Dπ = −0.032 ± 0.031 (stat.) ± 0.020 (syst.), c Dπ lep = −0.059 ± 0.055 (stat.) ± 0.033 (syst.) on the B 0 →D ± π ∓ sample, a D * π = −0.049 ± 0.031 (stat.) ± 0.020 (syst.), c D * π lep = +0.044 ± 0.054 (stat.) ± 0.033 (syst.) on the B 0 →D * ± π ∓ sample, and a Dρ = −0.005 ± 0.044 (stat.) ± 0.021 (syst.), c Dρ lep = −0.147 ± 0.074 (stat.) ± 0.035 (syst.) on the B 0 →D ± ρ ∓ sample.
