The asymmetry between same sign inclusive dilepton samples (l^+l^+ and l^-l^-) from semileptonic B decays in Upsilon(4S) -> B0 B0bar events allows us to compare the B0 mixing probabilities P(B0bar -> B0) and P(B0 -> B0bar), and hence to test T and CP invariance. We present a measurement of CP asymmetry in inclusive dilepton samples using the full BABAR dataset near the Upsilon(4S) resonance, which corresponds to 471 million BBbar pairs.
