  • Solution: Replacement or rebuild of the turbocharger. Check for oil leaks and ensure proper lubrication to the new turbo.
  • Estimated Cost to Fix: $1500 - $3000+ (including labor)
  • Recalls: None Found
• Cooling System Leaks (Radiator/Hoses)
  • Description/Symptoms: Overheating, coolant loss, visible leaks under the vehicle, low coolant warning light.
  • Solution: Replacement of leaking radiator, hoses, or water pump. Pressure test the system to identify all leaks.
  • Estimated Cost to Fix: $300 - $1000+ (including labor)
  • Recalls: None Found

Transmission

Manual Transmission (Specific type varies by region/application)

• Difficulty Shifting/Gear Grinding
  • Description/Symptoms: Difficulty engaging gears, grinding noise during shifting, especially between certain gears.
  • Solution: Adjustment or replacement of clutch components (clutch disc, pressure plate, throwout bearing). Inspection of shift linkages for wear or damage.
  • Estimated Cost to Fix: $500 - $1500+ (including labor)
  • Recalls: None Found

Automatic Transmission (Specific type varies by region/application)

• Harsh Shifting/Slipping
  • Description/Symptoms: Abrupt or jerky shifts, transmission slipping (engine revving without acceleration), failure to shift into certain gears.
  • Solution: Transmission fluid flush and filter change. If the problem persists, valve body repair or replacement, or complete transmission rebuild/replacement may be necessary.
  • Estimated Cost to Fix: $200 - $300 (fluid flush/filter), $800 - $3000+ (valve body/rebuild) (including labor)
  • Recalls: None Found

Suspension

• Air Suspension System Malfunctions (If equipped)
  • Description/Symptoms: Vehicle leaning to one side, failure to maintain ride height, compressor constantly running, error messages on the dashboard.
  • Solution: Inspection and repair of air struts, compressor, air lines, and height sensors. Replacement of faulty components.
  • Estimated Cost to Fix: $300 - $2000+ (depending on the component and labor)
  • Recalls: None Found

Electrical

• Sensor Failures (ABS, Wheel Speed, etc.)
  • Description/Symptoms: Warning lights on the dashboard (ABS, traction control), erratic system behavior, inaccurate readings.
  • Solution: Diagnosis with a scan tool to identify the faulty sensor(s). Replacement of defective sensors.
  • Estimated Cost to Fix: $150 - $400+ per sensor (including labor)
  • Recalls: None Found
• Wiring Harness Issues/Corrosion
  • Description/Symptoms: Intermittent electrical problems, lights not working, sensors malfunctioning, difficulty starting the engine.
  • Solution: Inspection of wiring harnesses for damage or corrosion. Repair or replacement of damaged sections.
  • Estimated Cost to Fix: $100 - $1000+ (depending on the extent of the damage and labor)
  • Recalls: None Found

Exterior

• Rust/Corrosion (Especially in colder climates)
  • Description/Symptoms: Rust forming on body panels, undercarriage, and frame.
  • Solution: Repair or replacement of affected body panels. Application of rust inhibitors and protective coatings.
  • Estimated Cost to Fix: Varies greatly depending on the severity of rust.
  • Recalls: None Found

Interior

• HVAC Blower Motor Failure
  • Description/Symptoms: Blower motor not working, weak airflow, unusual noises from the blower motor area.
  • Solution: Replacement of the blower motor. Inspection of the blower motor resistor.
  • Estimated Cost to Fix: $200 - $500+ (including labor)
  • Recalls: None Found

Summary

The 2006 Mercedes-Benz LO 915, while generally reliable, can suffer from issues related to its age and use as a commercial vehicle. Common problems include fuel injector failure, turbocharger issues, and cooling system leaks within the engine. Transmissions can have issues with shifting and gear grinding, which may require clutch or transmission repair. Electrical gremlins, often stemming from sensor failures or corrosion, are also prevalent. These issues can range from minor inconveniences to major repairs, with costs varying accordingly. Regular maintenance and prompt attention to warning signs are key to mitigating these problems.
