The BMW fault code typically indicates "Air system, air to EGR exhaust mass flow plausibility: Measured air mass too high". This means the engine's computer (DDE) detects more fresh air entering the engine than it expects, often because the Exhaust Gas Recirculation (EGR) system is not properly diluting the intake with exhaust gases.
