Diagnostic Procedures:
Troubleshooting charts, fault code interpretation (OBD-II), symptom-based diagnostics, testing of electrical components and sensors.
Repair Procedures:
Step-by-step instructions for component removal, installation, and repair across all covered systems, including engine rebuilds, transmission overhauls, brake system repairs, suspension component replacement, and electrical system fixes.
Torque Specifications:
Detailed torque values for critical fasteners throughout the vehicle, ensuring proper assembly and preventing damage.
Special Tools:
Identification and usage of Maserati-specific or specialized tools required for certain repair or diagnostic procedures.
Wiring Diagrams:
Comprehensive and detailed wiring schematics for all electrical systems, crucial for diagnosing and repairing electrical faults.
Depth Level:
Comprehensive - Covers everything from basic maintenance to complex engine and transmission rebuilds, electrical diagnostics, and chassis component repairs.
Oil Change Interval:
Typically every 10,000 - 15,000 km (6,000 - 9,000 miles) or 12 months, whichever comes first (refer to manual for exact specification).
Major Service Interval:
Significant services, including spark plugs, belts, and fluid changes, are usually recommended around 50,000 - 60,000 km (30,000 - 37,000 miles).
Engine Oil Spec:
API SN, ACEA A3/B4, fully synthetic 5W-40 or 0W-40 (e.g., Shell Helix Ultra Extra 5W-30, Castrol Edge Professional A3 0W-30 are often cited).
Engine Oil Capacity:
Approximately 7.5 - 8.0 Liters (with filter).
Coolant Type:
Ethylene glycol-based coolant, typically blue or pink, meeting specific Maserati standards (e.g., Paraflu UP).
Brake Fluid Type:
DOT 4 Class 6 or DOT 5.1 (Low Viscosity) recommended for ABS systems.
Common Complaints:
Potential for electrical gremlins (sensors, modules), clutch wear (on earlier single-clutch automated manuals, though this M139 has a ZF auto), suspension component wear (bushings, ball joints), catalytic converter failure, door handle microswitches, and infotainment system glitches.
Maintenance Focus:
Due to the Ferrari-derived engine and sophisticated electronics, regular and thorough maintenance is critical for reliability. VVT system components require attention.
