Mercedes Vito 2nd Generation: Review, Operation, and Weak Points

The second-generation Mercedes Vito (produced from 2003 to 2014) remains one of the most popular commercial minivans in Europe. It offers excellent features that make it suitable for both business and personal use. Despite its commercial nature, the Vito possesses many qualities typical of executive passenger vehicles, including an exceptionally high level of comfort.

Specifications and Trim Options

Engines and Powertrain

The second-generation Mercedes Vito features a broad selection of engines, making it a versatile vehicle for various needs. Available options include both diesel and gasoline engines, ranging from economical inline four-cylinders to powerful 3.0-liter V6 units.

Diesel Engines

The most popular engines are the inline-four diesel OM646 and OM651. These engines provide great fuel economy with solid performance. The OM646 delivers between 88 and 152 hp, while the facelifted OM651 produces from 95 to 190 hp. The range-topping OM642 V6 generates up to 224 hp and is ideal for those seeking enhanced dynamics and towing capacity.

Gasoline Engines

For gasoline enthusiasts, Mercedes initially offered the M112 engines with 3.2 and 3.7-liter displacements, later replaced by the M272 3.5-liter engine. However, gasoline versions are less common, as diesel models tend to be more economical and durable.

Trims and Body Variants

The Vito was offered in several configurations: a standard 3.2-meter wheelbase, an extended version 23 cm longer, and three body lengths of 4.7, 5.0, and 5.2 meters. The cabin can seat up to eight passengers, making it an excellent option for people transport.

Trim levels varied significantly, especially in the Viano version, which served as a more luxurious alternative to the commercial Vito.

Issues and Weak Points

Like any vehicle, the Mercedes Vito has its specific operational features and weak spots that buyers should be aware of.

OM651 Engine Characteristics

While the OM651 engine (which replaced the OM646 in facelifted models) is generally reliable, it has several known issues. A major concern is the variable-capacity vane oil pump. In some models, the valve that regulates oil pressure can malfunction, resulting in a loss of lubrication under heavy loads.

Vane failures are also reported, requiring oil pump replacement every 200,000-250,000 km. Initially, these engines were fitted with piezoelectric injectors, which were later replaced with more reliable electromagnetic ones.

Body and Corrosion Problems

Vehicles from the 2000s, including the Vito, were not perfectly protected against rust. The most vulnerable areas include sills, wheel arches, and door edges, where corrosion may develop over time. It's crucial to inspect these areas for rust or signs of amateur repairs.

Paint bubbling between the roof and side panels is another common issue, potentially indicating corrosion, especially in vehicles used in harsh, chemically aggressive environments.

Electrical Issues

Older Vito models are prone to electrical issues. Common problems include faulty starters or alternators, which can prevent the engine from starting or cause poor battery charging. Often, replacing the solenoid or regulator resolves these issues.

Radiator fan failures due to wire corrosion are also common but usually easy to fix with simple resoldering.

Suspension and Related Components

Suspension

The Vito's suspension is generally robust but includes some areas that require attention. Front lower control arm ball joints need periodic replacement, which involves cutting out the original rivets to install new components. Although the rear suspension is independent, the lower coils on the rear springs are known to break in some models.

Air Suspension

Some Vito variants feature air suspension in the rear. These components often fail by losing air pressure and causing the vehicle to sag. Many owners replace them with more affordable alternatives. Proper calibration is essential, and the absence of body height sensors can affect functionality.

Manual Gear Selector

The manual transmission in the Vito has a weak point in the gear selector mechanism, which can develop excessive play and make smooth shifting difficult. When inspecting a used Vito, ensure all gears engage easily and that reverse engages without delay.

Interior Comfort and Features

The Vito is justifiably considered one of the most comfortable commercial vehicles in its class. The interior is designed with attention to detail, ensuring great ergonomics. The Trend version includes full interior lining, lights, hooks, and various amenities, making it suitable for both private and commercial use.

The cabin features comfortable seating and a multimedia system for driver and passengers. With ample space for 7-8 people, the Vito is ideal for group travel. Post-facelift models feature an even more modern and appealing interior design, enhancing the overall impression.

Maintenance and Recommendations

Regular Maintenance

To avoid most of the potential problems with the Mercedes Vito, it's crucial to follow a regular maintenance schedule. As with most vehicles, routine oil, filter, and consumable changes can significantly extend the engine and component lifespan.

Also, monitor the suspension and gearbox condition, as wear can lead to expensive repairs.

Pre-Purchase Inspection

When buying a used Vito, pay attention to several key aspects. First, inspect the body for corrosion, especially around the sills, arches, and door frames. Also, check the air conditioning system, starter, alternator, and suspension condition.

Conclusion: Is the Second-Generation Mercedes Vito Worth Buying?

The second-generation Mercedes Vito is more than just a utilitarian van—it is a genuine all-rounder, equally capable as a workhorse or a family car. It blends practicality with meticulous German engineering and long-term reliability.

Despite its age, the Vito remains highly relevant on the used market, with steady demand. Its well-thought-out design, diverse engine range, and multiple body configurations make it easy to find a version tailored to any task—from cargo hauling to family or business travel.

Yes, the model has its quirks—temperamental injectors, corrosion-prone spots, a fragile manual gear selector, or aging air suspension. But these issues are well-documented, making them predictable and mostly manageable. The key is to carefully evaluate each vehicle's condition, service history, and body integrity.

If you find a well-maintained Vito with a solid body, functioning electronics, and a healthy drivetrain, it can be a smart investment—especially if you need a reliable daily partner for both cargo and long-distance travel.

The Mercedes Vito is a characterful vehicle. It demands attention, care, and regular upkeep, but it rewards owners with durability, versatility, and excellent ergonomics. And despite its commercial background, it retains the unmistakable Mercedes identity—style, quality, and charm.

So, if you're looking for a spacious, reliable, and relatively affordable minivan, the second-generation Vito should definitely be on your shortlist. Just make sure to inspect it thoroughly, top to bottom, to ensure it becomes a loyal companion and not a frequent visitor to the workshop.
