Compatible with models such as the F22, F23, F30, F32, F33, and F36, this OEM ECU (part number 9486260) is pulled from a 2018 BMW 330i (VIN: WBA8B9C59JEE81797) with just 47,479 miles.

The DME (Digital Motor Electronics) module is the brain of your engine, responsible for fuel mapping, ignition timing, and emissions control. This specific unit is designed for the B46O engine and is ideal for those needing a direct OEM replacement after ECU failure, water damage, or tuning reset.
