Description
This Battery Energy Management Module is an original Audi electronic control unit for Audi A8 and S8 D3 4E models. The primary OEM number is 4E0915181C, with alternate hardware reference 0199000015. It is designed as the vehicle’s battery monitoring and energy management controller, helping support stable electrical operation across the onboard network.
Its job is to monitor battery condition, track voltage behavior and manage power use within the car’s electrical system. By coordinating energy distribution and protecting the battery during high demand or low charge situations, this module helps the vehicle maintain reliable starting, charging and system communication.
Common signs of a faulty unit include battery drain, repeated low-voltage warnings, charging system faults, intermittent electrical malfunctions, difficulty starting, or comfort systems shutting down unexpectedly. In some cases, owners may notice irregular battery monitoring messages or energy management related fault codes stored in the vehicle.
This is a used original part, removed from a vehicle and tested before sale. Match 4E0915181C and 0199000015 with your existing unit before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and system setup.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
