Description
This electronic parking brake EPB module is a genuine Audi control unit for Audi A8 and S8 D3 4E models. The primary OEM number is 4E0907801, with hardware reference 5WK3244 also matching this unit. It is an original electronic brake system component designed for the vehicle platform named here.
Its job is to control and monitor the electronic parking brake system, processing signals and commanding the parking brake functions as part of the vehicle’s brake electronics. A correct working module helps the system apply and release the parking brake properly and communicate with other control units.
Common signs of a faulty unit include parking brake warning messages, failure to apply or release the brake correctly, intermittent brake faults, stored control module errors, or loss of communication during diagnostics. In some cases, drivers may notice warning lights or restricted parking brake operation.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 4E0907801 and hardware reference 5WK3244 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required after fitting.
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.
