The Mercedes-Benz Sprinter 3.5-t (W906), produced from 2008 to 2018, is a staple of New Zealand's commercial landscape. It’s renowned for its durability, versatility, and robust carrying capacity, making it a favoured choice among businesses of all sizes. However, the demands placed on this workhorse call for regular maintenance and attention to detail. As a Kiwi mechanic, I've seen firsthand how crucial it is to care for your Sprinter to keep it running smoothly and compliant with WOF requirements. In this guide, we'll delve into common maintenance practices, essential services, and how to ensure your Sprinter remains a reliable asset for your business.
Common Sprinter issues in NZ include: 1. <b>DPF clogging:</b> Especially in vans used primarily for short trips. 2. <b>Injector failures:</b> Can lead to poor performance and increased fuel consumption. 3. <b>Suspension wear:</b> Leaf springs, shock absorbers, and ball joints are all common wear items. 4. <b>Rust:</b> Check the bodywork, especially around the wheel arches, sills, and under the floor. 5. <b>Turbocharger failures:</b> Due to oil starvation and overuse.
During a WOF inspection, pay special attention to: 1. <b>Brake condition:</b> Check brake pads, rotors, and brake lines for wear and damage. Ensure the parking brake functions correctly. 2. <b>Tyre condition:</b> Tyres must meet legal tread depth requirements and be suitable for the vehicle's load rating. 3. <b>Lighting:</b> All lights (headlights, taillights, brake lights, indicators) must be functioning correctly. 4. <b>Suspension components:</b> Inspect leaf springs, shock absorbers, and ball joints for excessive play or damage. 5. <b>Rust:</b> Check the bodywork and chassis for rust, particularly around critical structural areas.
The Sprinter’s reliability is generally strong, yet high mileage and the demands of daily use can lead to some common challenges. Regular servicing is essential to keep it in optimal condition. Pay particular attention to the suspension system and drivetrain—parts that endure the greatest stress under heavy loads. Look out for components like leaf springs, shock absorbers, and ball joints; these are vital for a stable ride. Routine oil changes and brake maintenance every 10,000 to 15,000 km can significantly extend the lifespan of your vehicle.
Across its lifespan, typical issues include the Diesel Particulate Filter (DPF) clogging and injector failures, which can lead to a decrease in performance and increased fuel consumption. Make a habit of inspecting your Sprinter frequently, especially after it crosses 150,000 km, which is when the cooling system components, including the water pump and thermostat, should be examined.
