The Mercedes-Benz Sprinter 3.5t (van) from 2006 to 2009 is an iconic presence on New Zealand roads, serving as a dependable workhorse for enterprises of every scale. Renowned for its spaciousness, versatility, and sturdy construction, this van has carved out a niche as the trusted ally of tradespeople, couriers, and transport services. However, as these vehicles age, proper maintenance is crucial to prolonging their lifespan and ensuring peak performance.
Common problems with the 2006-2009 Sprinter 3.5t include injector issues (leading to rough running and potential engine damage, especially on the earlier CDI engines), turbocharger failures (characterized by a loss of power and excessive smoke), and issues with the EGR valve (resulting in poor performance and increased emissions). Rust can also be a concern, particularly in areas prone to moisture and salt. Driveline issues, like worn driveshaft or diff seals, are common. Also common is door locks failing - so factor this into any purchase!
When presenting your Sprinter for a WOF, pay close attention to the brakes (especially the parking brake), suspension (check for worn bushes and ball joints), and tires (ensure they meet the required load rating). As a commercial vehicle, it will be inspected more stringently than a passenger car. Headlight alignment is critically important on commercial vehicles. Rust is a common cause of failures, particularly on older models, so inspect carefully. WOF failures for brakes and suspension are common.
The 2006-2009 Sprinter 3.5t showcases an array of configurations tailored to various business needs, including diverse wheelbase lengths, roof heights, and engine arrangements. Predominantly featuring diesel models, these vans excel in marrying power with fuel efficiency, making them suitable for commercial responsibilities. Key components often require attention around important service intervals; for example, the cooling system should be inspected at around 150,000 km, with parts such as the water pump, thermostat, and radiator hoses needing checks or replacements.

However, it’s essential to address common concerns like injector issues leading to rough engine performance, turbocharger faults characterized by power loss, and EGR valve malfunctions to maintain operational effectiveness. To keep your Sprinter running at its best, regular checks on vital systems including braking [link to /shop/braking] and filtration [link to /shop/filtration] will ensure durability and reliability, fulfilling the high expectations of owners who depend on this remarkable vehicle.
