The Mercedes-Benz Sprinter 3,5-t is a cornerstone of New Zealand's commercial vehicle landscape, celebrated for its versatility and robust load-carrying capabilities. The upgraded 2009-2018 models feature enhanced fuel efficiency, advanced safety features, and an overall more comfortable driving experience. Ideal for tradespeople, couriers, and even camper conversions, this van is built to withstand the demands of daily commercial use. However, just like any hardworking vehicle, proper maintenance is essential to unlock its full potential. Here’s everything you need to know before making a purchase.
Common problems on the 2009-2018 Sprinter 3,5-t include turbocharger failures, diesel particulate filter (DPF) clogging (especially on vans used primarily for short trips), and injector issues. Suspension components, such as leaf springs and shock absorbers, can also wear out prematurely due to heavy loads. Electrical problems, such as failing sensors and wiring corrosion, are not uncommon. Rust, while generally less of a concern than on older vans, can still occur around the wheel arches, sills, and below the windscreen, especially in coastal areas.
During a WOF inspection, pay close attention to the brakes, including the condition of the pads, rotors, and brake lines. Check the suspension for signs of wear or damage, particularly the leaf springs and shock absorbers. Ensure all lights, including headlights, taillights, and indicators, are functioning correctly. The exhaust system must be free of leaks, and the DPF (if fitted) must be functioning correctly. Check tire condition, making sure thread wear is even and meets warrant standards. Excessive engine smoke can also result in a WOF failure. Due to the commercial nature of these vehicles, make sure all safety requirements for commercial vehicles are met.
These Sprinters have become the go-to choice for various commercial applications, renowned for their efficient diesel engines that deliver excellent torque while keeping fuel consumption manageable. Whether equipped with a manual or increasingly popular automatic transmission, they are built to handle a range of driving conditions — from bustling city traffic to long highway hauls. Regular maintenance is paramount; be sure to look for documented service history, particularly for common replacement parts such as brake pads, air filters, and wiper blades. Understanding service intervals can significantly reduce downtime; for instance, it’s advisable to inspect the braking system at every 15,000 km. Maintaining the cooling system is also key, especially around the 150,000 km mark, which necessitates checking the water pump, thermostat, and radiator hoses.

Don't forget to stock up on brake components and air filters while you're at it. [Refer to /shop/braking and /shop/filtration for these parts.]
