Working on a 2015 gl550 with m278. Multiple fault codes lead to me to quickly find out fuse 216 was blown. New fuse blows instantly when power is supplied from circuit 87 relay. My wiring diagrams show fuse 216 powers multiple z splices. Z7/48, z7/36z1, z7/36z2 and maybe more.. Some components include purge valve, control side of engine fan, charcoal canister valve, several o2 sensors, cam solenoids etc etc. I have tried unplugging every easy to reach component I've found on diagram. Any help or suggestions thank you.

Omg I need to learn how to read new mb fuseboxes. My fuse that was blowing was fuse 215. They label numbers in order but not correctly next to fuse on plastic fusebox. The number 2 ignition coil was blowing the fuse 215.... solved!!!!
