Description
This BMW DC/DC converter is an original used electrical unit with OEM number 9113348. It is fitted in selected BMW models, although specific model codes are not provided here, and is designed as a genuine factory energy management component for the vehicle’s power supply system.
Its job is to regulate and convert electrical voltage within the vehicle so connected systems receive the correct power supply. In BMW applications, this type of converter helps stabilize onboard voltage and supports reliable operation of electronic systems that depend on consistent current.
Common signs of a faulty unit include charging-related warnings, intermittent electrical faults, unstable voltage supply, battery drain, difficulty powering certain control systems, or communication errors between electrical modules. Because this part works within the vehicle’s energy management network, failure can create a wide range of electrical symptoms.
This is a used original part removed from a vehicle and tested before sale. Please match OEM number 9113348 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle and system 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.
