The Mercedes-Benz Vito, V350, and Mixto (W639) models produced between 2010 and 2014 represent a versatile range of commercial and passenger vehicles, finding popularity in New Zealand for their practicality and durability. While these vans are known for their robust construction and capacity, they are not immune to issues, especially as they age. This guide highlights common problems, WOF considerations, and preventative maintenance strategies specifically for Kiwi drivers.
Vito/V350/Mixto common problems in NZ:
• Injector issues (Diesel models): Diesel injectors can become clogged or fail, leading to poor performance, rough idling, and increased fuel consumption. NZ fuel quality variations can accelerate this.
• Dual-mass flywheel (DMF) failure: DMF failure can cause excessive vibration and noise, eventually requiring costly replacement. This is especially common in manual transmission models used for heavy hauling.
• Sliding door problems: The sliding doors, a key feature of these vans, can experience issues with rollers, latches, and cables, making them difficult to open or close smoothly.
• Rust: Lower body panels in particular, along with tailgate rot, which if left unchecked will compromise WOF standards.
Critical WOF inspection points:
• Brake system: Thorough inspection of brake pads, rotors, lines, and hoses is crucial. The parking brake must also function effectively.
• Suspension: Check for worn ball joints, bushings, and shock absorbers, especially given the heavy loads these vans often carry.
• Tyres: Ensure tyres meet the minimum tread depth requirements and are suitable for the vehicle's load rating.
• Lighting: All lights must be in good working order, including headlights, taillights, brake lights, and indicators. Check for proper beam alignment of the headlights.
• Structural integrity: Any rust or damage that compromises the vehicle's structural integrity will result in a WOF failure.
The Vito served primarily as a workhorse, offering a range of body styles and configurations for various commercial applications. The V350 represented a more luxurious people-mover variant, while the Mixto combined cargo-carrying capabilities with passenger seating. These vans provided practical solutions for businesses and families alike in New Zealand. However, due to their often demanding usage, diligent maintenance is paramount.
