The DEF Pack mod is recommended to simulate the new DEF systems.
The DEF Mod Pack and Variable Tire Pressure mods can be used together without any compatibility issues.

Your engine wears out. Your oil gets dirty. Your turbo fails if you never maintain it. This is what “realistic maintenance” should have meant from the beginning.
Hyper Realistic Maintenance 2 adds deep, continuous mechanical simulation to all motorized vehicles in your saved game — tractors, trucks, harvesters and cars — with real gameplay consequences, not just cosmetic numbers.
What is simulated
Engine: 5 independent components (cylinder, piston, bearings, crankshaft, valves) that influence each other — cylinder wear increases blow-by, which contaminates the oil and accelerates wear even further
Thermal: coolant temperature increases with load and the engine overheats if the radiator is degraded
Fluids: oil level/contamination and coolant level, both checkable and requiring maintenance
Transmission: clutch, gearbox, turbo and battery/starter motor wear over time
Failures: probabilistic failures that increase sharply above approximately 35% wear on the relevant component — critical overheating above 118 °C is guaranteed and does not depend on luck
Behaviour by vehicle type: tractors, trucks, harvesters and cars wear at different, realistic rates
Real effects, not cosmetic ones
Real power loss — reduces the engine’s effectively available torque; you will feel it in the field
Real no-start conditions — a flat battery or worn starter motor can actually prevent the engine from turning over, with a warning displayed on screen
Harvesters suffer a real loss of threshing efficiency as the engine condition deteriorates
Scheduled maintenance, just like in real life
10 maintenance items (engine oil, filters, hydraulic/transmission oil, coolant, grease, belts and much more), each with its own interval and a real cost for the farm — automatically adjusted to the vehicle’s actual power. If you neglect maintenance for too long, wear accelerates by up to +120%.
Vehicle HUD with 3 pages — overview, detailed engine diagnostics and maintenance status — with an adjustable position in the game Settings menu. The game’s own repair screens (shop, farm workshop, mobile workshop) now also perform a complete HRM2 service.
Compatibility: works completely standalone. If you also have the 4×4 Traction System mod, the two mods detect each other automatically, and 4WD/differential lock driving gains a real additional effect on the transmission. Significantly improved multiplayer, tested on a real dedicated server (see the changelog for details and known limitations). Maintenance progress is saved in the saved game.
V3.1.4.0
Fixed: the maintenance window (Left Alt + M) did not open inside a vehicle. It now opens on foot and in the vehicle.
New: the instrument cluster can be moved. In the window, go to Settings > Cluster position > Move with the mouse, then drag it to where you want. Right click or Esc to finish. Reset puts it back in its original place.
Fixed (multiplayer): the cluster position, cluster size, cluster on/off and work sounds are now saved for each player. Before, the server and the savegame overwrote them for everyone.
