This used OEM Mercedes-Benz Relay / Fuse Box (part 2135404478) came from a donor vehicle. It routes power through relays and fuses to various electrical circuits. In these 2.0L turbocharged, mild-hybrid, and plug-in hybrid engines, a failing unit can cause sporadic electrical gremlins—lights flickering, windows or locks not responding, or starting issues. Alternate names: Relay Box, Fuse Box.
