The 2008 Mercedes-Benz Gran Viale Articulado is a large, articulated bus primarily used in public transportation. While specific horsepower and torque figures may vary slightly depending on regional configurations and fine-tuning, a typical engine option for this model is the Mercedes-Benz OM 457 hLA, a turbocharged and intercooled inline-6 diesel engine producing around 299 hp (220 kW) and significant torque. Common positive remarks about the Gran Viale Articulado include its high passenger capacity, robust build designed for heavy-duty use, and comfortable ride. Conversely, common dislikes often revolve around the complexities of maintaining such a large vehicle, especially the articulated joint, and potential issues related to the advanced systems integrated into the bus.

Engine

Mercedes-Benz OM 457 hLA (Inline-6 Diesel)

  • Fuel Injector Failure
    • Description/Symptoms: Rough idling, decreased fuel efficiency, black smoke from the exhaust, and potential engine stalling. The engine may have trouble starting.
    • Solution: Replace faulty fuel injectors. Proper diagnosis with a diagnostic tool is necessary to pinpoint the problematic injector(s).
    • Estimated Cost to Fix: $300 - $800+ per injector (including labor and parts)
  • Turbocharger Failure
    • Description/Symptoms: Loss of power, excessive black or blue smoke, and unusual whistling or grinding noises from the turbocharger area. Oil leaks can also occur.
    • Solution: Replacing the turbocharger with a new or remanufactured unit. Inspecting and cleaning the intercooler and related hoses is also recommended.
    • Estimated Cost to Fix: $1500 - $4000+ (including labor and parts)
  • Coolant Leaks
    • Description/Symptoms: Coolant leaks can occur from the water pump, radiator, hoses, or head gasket. Overheating may be a symptom if the leak is significant.
    • Solution: Identify and repair the source of the leak. This could involve replacing hoses, gaskets, or the water pump. In severe cases, head gasket replacement might be necessary.
    • Estimated Cost to Fix: $100 - $200 (hose replacement), $500 - $1500 (water pump), $2000 - $5000+ (head gasket)

Transmission

ZF Ecomat 6HP602 (Automatic)

  • Slipping Gears
    • Description/Symptoms: The transmission slips between gears, especially under heavy load or when accelerating. The engine RPMs may increase without a corresponding increase in speed.
    • Solution: A rebuild or replacement of the transmission, depending on the severity of the damage. A fluid change may temporarily alleviate the issue, but it is unlikely to be a permanent fix.
    • Estimated Cost to Fix: $300 - $500 (fluid change), $3000 - $7000+ (rebuild/replacement)
  • Harsh Shifting
    • Description/Symptoms: Abrupt and harsh shifts between gears, particularly noticeable during upshifts and downshifts. Jerking motions may occur.
    • Solution: Could be related to valve body issues or worn solenoids. Replacing these components or rebuilding the valve body can often resolve the problem.
    • Estimated Cost to Fix: $800 - $3000+ (valve body repair/replacement)
  • Delayed Engagement
    • Description/Symptoms: A delay in engagement when shifting from park or neutral into drive or reverse. The bus may hesitate before moving.
    • Solution: Can be related to low transmission fluid, filter blockage, or internal transmission damage. Requires diagnosis to determine the root cause.
    • Estimated Cost to Fix: $100 - $300 (fluid and filter change), $1000 - $5000+ (internal repair/replacement)

Suspension

  • Air Suspension Compressor Failure
    • Description/Symptoms: The bus may sag or lean to one side due to uneven air pressure in the air springs. The compressor may run constantly or fail to activate at all.
    • Solution: Replacing the air suspension compressor. Check for leaks in the air lines and springs as well.
    • Estimated Cost to Fix: $500 - $2000+ (including labor and parts)
  • Air Spring Leaks
    • Description/Symptoms: Hissing sounds coming from the air springs. The bus may lean or sag. Reduced ride quality.
    • Solution: Replacing the leaking air spring(s).
    • Estimated Cost to Fix: $300 - $1000+ per spring (including labor and parts)

Electrical

  • Multiplex Wiring Issues
    • Description/Symptoms: Erratic behavior of electrical systems, such as lights flickering, instrument panel malfunctions, or intermittent failures of other electronic components.
    • Solution: Diagnosing and repairing the multiplex wiring system. This may involve tracing wires, replacing faulty modules, and reprogramming the system.
    • Estimated Cost to Fix: $500 - $3000+ (depending on the complexity of the issue)
  • Sensor Failures
    • Description/Symptoms: Engine management, safety, and transmission sensors can fail leading to rough running, transmission issues, ABS activation, etc.
    • Solution: Replace failed sensors. Requires proper diagnosis with a diagnostic tool.
    • Estimated Cost to Fix: $150 - $500+ per sensor (including labor and parts)

Exterior

  • Articulated Joint Issues
    • Description/Symptoms: Squeaking, grinding, or clunking noises coming from the articulated joint. Difficulty maneuvering or instability when turning. Visual inspection may reveal wear or damage.
    • Solution: Lubricating, repairing, or replacing the components of the articulated joint. This may involve replacing bearings, bushings, or the entire joint assembly.
    • Estimated Cost to Fix: $1000 - $10,000+ (depending on the severity of the issue)

Interior

  • HVAC System Malfunctions
    • Description/Symptoms: Inadequate heating or cooling, unusual noises from the HVAC system, or a complete failure of the system.
    • Solution: Diagnosing and repairing the HVAC system. This may involve replacing the compressor, condenser, evaporator, or other components. Refrigerant leaks must also be addressed.
    • Estimated Cost to Fix: $300 - $2000+ (depending on the nature of the problem)

Summary

The 2008 Mercedes-Benz Gran Viale Articulado, while a reliable workhorse for public transportation, presents owners with several potential maintenance challenges. Engine and transmission issues, particularly those related to fuel injectors, turbochargers, and transmission wear, can be costly to repair. Suspension and electrical system problems, as well as issues with the articulated joint, are also common. The severity and cost of these issues range from minor repairs to major overhauls, making it crucial to conduct thorough inspections and preventative maintenance to minimize downtime and expenses.
