Most common problems, symptoms & fixes for the M104 engine.
Engine M104 is a robust inline-six engine known for its durability, but common issues include oil leaks from valve cover gaskets and camshaft seals, coolant leaks due to aging hoses or radiator problems, and occasional ignition system faults like worn spark plugs or coil packs.
