Description
This BMW DC/DC converter is a used original electronic power module for BMW vehicles. Primary OEM number 9127088 is the key identifier for this unit. It is designed as a DC/DC converter that supports the vehicle’s low-voltage electrical supply and battery management functions.
Its job is to convert and stabilize electrical power within the vehicle so essential 12-volt systems receive the correct voltage. In BMW applications, this type of converter helps support onboard electronics, charging balance and reliable operation of multiple control systems that depend on steady low-voltage power.
Common signs of a faulty unit include battery charging warnings, low-voltage faults, intermittent electrical malfunctions, start-stop irregularities, warning messages on the dashboard or unstable operation of comfort and control electronics. Voltage-related issues can also lead to communication faults between modules.
This is a used original part removed from a vehicle and tested before sale. Match the exact OEM number 9127088 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle system and replacement procedure.
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.
