Description
This is a genuine Audi battery energy management module for Audi A8 S8 D3 4E models, supplied under OEM number 4E0915181 with alternate reference 0199000006. It is an original electronic control unit used within the vehicle’s battery monitoring and power management system.
Its job is to monitor battery condition, manage electrical power demand and help protect vehicle systems during charging and discharge cycles. By communicating battery status to the car’s electrical network, it supports stable voltage control and helps the vehicle respond correctly to changing load conditions.
Common signs of a faulty unit include recurring battery drain, charging system warnings, unexplained low-voltage faults, comfort functions shutting down early or intermittent electrical behavior. In some cases, the vehicle may store battery management or power supply related fault codes.
This is a used original part, removed from a vehicle and tested before sale. Match 4E0915181 and 0199000006 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle configuration.
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.
