Vehicle Specs & Maintenance Data
The 2013 Mercedes-Benz Ml-Class maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Mercedes-Benz Ml-Class.
For oil changes, the 2013 Mercedes-Benz Ml-Class takes 0W-40 Full Synthetic motor oil with a capacity of 8 quarts. Brake fluid type is DOT 4, the recommended coolant is MB 325.0 (Blue, silicate-free), and transmission fluid is MB 236.14. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Mercedes-Benz Ml-Class, torque the lug nuts to 96 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Diesel Intake Manifold Swirl Flap Failure (OM642)
The OM642 3.0L diesel V6 intake manifold swirl flaps can break apart and be ingested into the engine, causing catastrophic damage. The plastic flaps become brittle over time and break at the pivot points.
Remove the intake manifold and delete the swirl flaps or install an aftermarket delete kit. If flap debris has entered the engine, a complete engine inspection and possible rebuild is required. This is a critical preventive maintenance item.
Est. Cost: $600 (delete kit) - $10,000+ (engine damage)Transfer Case Actuator Motor Failure
The 4MATIC transfer case actuator motor fails, preventing proper torque distribution between the front and rear axles. The vehicle may display drivetrain warnings and lose AWD capability.
Replace the transfer case actuator motor. The transfer case fluid should be changed simultaneously. A software recalibration of the 4MATIC system is required after replacement.
Est. Cost: $800 - $2,000Air Suspension Strut Leaks
The AIRMATIC air suspension struts develop air leaks from deteriorating rubber bladders. The vehicle sags at one or more corners, particularly overnight. The compressor runs excessively trying to maintain height.
Replace the leaking air struts. Aftermarket options from Arnott or Bilstein are available at lower cost than OEM Mercedes parts. Replace the air dryer to protect the new struts from moisture contamination.
Est. Cost: $1,200 - $3,000 per strutDEF System Malfunctions (BlueTEC)
The AdBlue/DEF system develops pump failures, heater element faults, and quality sensor errors. The vehicle counts down to an engine start inhibit if DEF faults are not resolved, eventually preventing the engine from starting.
Replace the DEF pump, quality sensor, or heater element as diagnosed. Only use high-quality DEF from a reputable supplier. Mercedes TSBs provide diagnostic procedures for the various DEF system fault codes.
Est. Cost: $800 - $3,000Rear Differential Mount and Bushing Wear
The rear differential mounts and subframe bushings wear out, causing clunking noises from the rear during acceleration and deceleration. The worn mounts allow the differential to shift, potentially causing driveline vibrations.
Replace the rear differential mounts and subframe bushings. Use OEM or upgraded aftermarket mounts. An alignment should be checked after the replacement to ensure proper driveline angles.
Est. Cost: $500 - $1,500
