Power Distribution Fuse Box 4K0941828F Audi A7 S7 4K C8 OE

Main Power Distribution Block / High-Current Fuse Box – 4K0941828F

Original power distribution module and main fuse block (power distribution block / electrical system power node – Stromverteiler), 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 / 340 hp) and 2.0 TFSI (40/45 TFSI) petrol engines, S7 and RS7 variants, and TDI diesel engines with Mild Hybrid (MHEV 12V / 48V) systems, based on the modular MLBevo longitudinal platform.

Original VAG high-current electrical system component. It consists of a heat-resistant housing made of non-flammable plastic, solid copper busbars, integrated blade and strip fuse sockets, and screw terminals for the main power supply lines. It is responsible for safely distributing power from the battery and alternator to the main branches of onboard consumers (including the electric power steering, ABS/ESP module, radiator fans, fuel pump, and BCM body control network controllers), protecting the electrical system against the effects of short circuits and overcurrents.

Fitment guarantee and VIN verification

Each power distribution block undergoes an internal conducting busbar continuity test, fuse socket condition inspection and contact cleanliness verification before shipping.

Fitment / installation note: The initial designation 4K0 (electrical group 941 / 828) with index F defines the high-current busbar and fuse configuration for the MLBevo platform's digital architecture. Damage to the distribution block (usually caused by a short circuit, a burnt power pin due to loose tightening, or flooding) results in a complete loss of power to selected systems, random CAN/LIN bus communication errors in the controllers, lights going out, or no response to the Start/Stop button. Installing an original OEM distribution block ensures factory-standard surge current resistance and trouble-free fitting of factory wiring harnesses. Before purchasing, we recommend comparing the OE number stamped on the distribution block housing or verifying it using the vehicle's VIN.
