BMW Upper ECU Housing / Engine Module Cover OEM 7521582 is a genuine used part removed from a donor vehicle. This cover protects the engine control module from moisture, heat, and debris on 2.2L, 2.5L, 3.0L, and 3.2L inline-six naturally aspirated engines. Also known as the engine module cover or upper ECU housing, it shields a critical electronic component—a cracked or missing cover can expose the ECU to water intrusion and costly failure.
