Main Power Distribution Block / High-Power Fuse Box – 4K0941823H

Original power distribution module and high-current main fuse block (electrical system power distribution terminal / main fuse box), designed for Audi A7 Sportback, S7 and RS7 (4K / 4K8 generation) and Audi A6 C8 (type 4K2 / 4K5 / 4KA) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI), 2.0 TFSI (40/45 TFSI), TDI diesel engines, and top-spec 2.9 TFSI (S7) and 4.0 V8 TFSI (RS7) models based on the modular MLBevo longitudinal platform.

Original VAG electrical system component. Mounted in the battery area in the trunk or the main power compartment under the vehicle floor. It is responsible for the safe and stable distribution of voltage to the vehicle's key onboard buses (including the starter, alternator, comfort modules, electric power steering, and Mild Hybrid system converter). It protects the main circuits against overload, short circuits, and voltage drops, ensuring the proper operation of all onboard electronics.

Fitment guarantee and VIN verification

Each power distribution block undergoes an inspection of the power bars for overheating and a check of the fuse slots before shipping.

Fitment / installation tip: The base designation 4K0 941 823 H (electrical system group 941) is the main power distribution module of the MLBevo platform. Replacement of this component is recommended in the event of burnt contacts, a short circuit in the electrical system, or mechanical damage to the power cable mounting slots. Using an original OEM power distribution block ensures factory electrical conductivity and full safety of the onboard installation. Before purchasing, we recommend comparing the letter of the OE index on your part's label or verifying it using the vehicle's VIN.
