This genuine Audi fuse box / relay plate, OEM 8K1937503C, is a used component removed from a donor vehicle. Also known as a relay plate, it houses the fuses and relays that distribute power and protect circuits throughout the electrical system. Compatible with multiple engines including 2.0L turbo fours and 3.0L supercharged V6s found in Audi A4, A5, Q5, and Porsche Macan models. A failing unit can cause intermittent electrical failures, no-start conditions, or blown fuses due to internal corrosion or melted terminals.
