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 B0 mixing probabilities P(B0bar -> B0) and P(B0 -> B0bar), and therefore to test the T and CP invariance. We present the measurement of CP asymmetry in inclusive dilepton samples with the full BABAR dataset near the Upsilon(4S) resonance, corresponding to 471 million BBbar pairs.
