Hyper Realistic Maintenance 2 für Farming Simulator 25

Your engine wears out. Your oil gets dirty. Your turbo fails if you never service it. This is what "realistic maintenance" should have meant all along.
Hyper Realistic Maintenance 2 adds a deep, ongoing mechanical simulation to every motorized vehicle in your save — tractors, trucks, harvesters, and cars — with real gameplay consequences, not just cosmetic numbers.
What it simulates
Engine: 5 independent components (cylinder, piston, bearings, crankshaft, valves) that influence each other — cylinder wear increases blow-by, which contaminates your oil, which accelerates wear further
Thermal: coolant temperature rises with load and overheats if your radiator is degraded
Fluids: oil level/contamination and coolant level, both trackable and serviceable
Drivetrain: clutch, gearbox, turbo, and battery/starter wear over time
Failures: probabilistic breakdowns that ramp up sharply past ~35% wear on the relevant component — critical overheating above 118°C is guaranteed, not luck
Per-vehicle-type behavior: tractors, trucks, harvesters, and cars wear at different, realistic rates
Real effects, not cosmetic
Genuine power loss — reduces actual available engine torque, you'll feel it in the field
Real no-start conditions — a dead battery or worn starter can actually stop your engine from turning over, with an on-screen warning
Harvesters lose real threshing efficiency as engine health degrades
Scheduled maintenance, like the real thing
10 serviceable items (engine oil, filters, hydraulic/transmission oil, coolant, grease, belts, and more), each with its own interval and a real farm-money cost — scaled automatically to the vehicle's actual horsepower. Let service slide too long and wear accelerates up to +120%.
3-page in-vehicle HUD — overview, detailed engine diagnostics, and maintenance status — position adjustable from the in-game Settings menu. The game's own repair screens (store, farm workshop, mobile workshop) now perform a full HRM2 service too.
Compatibility
Runs entirely standalone. If you also install the 4x4 Traction System mod, the two detect each other automatically — their HUDs won't overlap, and running in 4WD/diff-lock adds a touch of extra, realistic drivetrain stress. Neither mod requires the other.
Singleplayer only for now; state isn't yet saved to the savegame (see the README for the honest list of current limitations).
