Description
This electronic parking brake EPB module is a genuine Audi control unit for Audi A6, S6 and C6 4F models. The primary OEM number is 4F0907801, with hardware reference 5WK32443. It is the brake system module responsible for managing the vehicle’s electronic parking brake functions and communication within the EPB system.
Working as the EPB control unit, it receives commands from the parking brake switch and coordinates the application and release of the rear parking brake motors. It helps maintain secure vehicle holding when parked and supports smooth, controlled operation of the electronic handbrake system.
Common signs of a faulty unit include a parking brake warning light, EPB malfunction messages, the brake failing to apply or release correctly, or stored control module faults during diagnostics. Intermittent operation, warning chimes, or reduced confidence in parking brake response can also point to a failing module.
This is a used original part, removed from a vehicle and tested before sale. Match 4F0907801 and 5WK32443 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required after fitting depending on 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.
