What to Check Before Buying
Maintaining a Mercedes-Benz Sprinter, encompassing models from the Mercedes Benz Sprinter 2006 through the Mercedes Benz Sprinter 2017, is paramount for ensuring its longevity and optimal performance. The W906 Sprinter has a mixed but generally serviceable reliability reputation; it proves robust when properly maintained, but it can quickly become an expensive proposition if critical emissions and sensor issues are ignored. The most significant financial exposure for owners often revolves around DEF/DPF/emissions repair, especially if the van is frequently used for short trips or operates with poor diesel quality. These conditions prevent the exhaust temperature from stabilizing sufficiently for proper diesel particulate filter regeneration, leading to soot load buildup and potential DPF saturation. Regular DPF saturation checks are vital to avoid costly replacements, which can affect models like the Mercedes Benz Sprinter 2011 and Mercedes Benz Sprinter 2012.
Conversely, the most affordable recurring issue is typically a fuel filter service, provided it's performed according to the recommended schedule. Mercedes-Benz's W906 maintenance booklet provides a clear service cadence, recommending oil service plus at 15,000 miles, maintenance service at 30,000 miles, and a fuel filter change every 30,000 miles. Air filter elements should be replaced every 45,000 miles. DEF checks and top-ups are recommended every 15,000 miles. Automatic transmission service, including fluid and filter replacement, is advised every fourth engine oil change to prevent harsh shifts and premature transmission damage, a common concern for models like the Mercedes Benz Sprinter 2009 and Mercedes Benz Sprinter 2010. Brake fluid should be renewed every two years to prevent moisture absorption and potential ABS corrosion risk, while coolant renewal is suggested every sixth Service B or 15 years, and rear axle oil every sixth Service B or 10 years.
Real-world operating conditions can significantly impact these maintenance intervals. For instance, dusty climates necessitate shorter air filter and cabin filter replacement intervals than the factory baseline, affecting models such as the Mercedes Benz Sprinter 2013 and Mercedes Benz Sprinter 2014. Low-quality diesel or water contamination can accelerate fuel filter and injector problems, underscoring the need for careful fuel sourcing. Heavy payload use will naturally cause brake and suspension service items, like shock absorbers and tie rods, to require attention much sooner than the factory schedule suggests, impacting the Mercedes Benz Sprinter 2015 and Mercedes Benz Sprinter 2016, which are often used for demanding commercial tasks.
Neglected service history dramatically increases the chance of emissions-related faults and reduces resale confidence across all model years, including the Mercedes Benz Sprinter 2017. For instance, owners of the Mercedes Benz Sprinter 2011 and Mercedes Benz Sprinter 2012 often report warning lights related to emissions or sensor issues, which become expensive to address if ignored. Before buying a used W906 Sprinter, a thorough pre-purchase inspection is essential. This should include checking service records, scanning for stored fault codes, performing cold starts to assess engine behavior, confirming smooth transmission behavior, inspecting brake wear, and verifying that the DPF/DEF system is not showing repeated warnings. Examine the underside for corrosion, suspension wear, and any signs of consistent overload use, as many Sprinters lead demanding commercial lives. This advice is particularly relevant for the Mercedes Benz Sprinter 2007 and Mercedes Benz Sprinter 2008 models, which may have accumulated significant mileage.
The engine, particularly the 3.0L V6 diesel, is generally long-lived if oil, fuel, and cooling systems are meticulously maintained, often exceeding 200,000 miles in fleet use. The transmission generally exhibits durability with fluid service on schedule, though deferred servicing significantly raises the risk of issues. Suspension wear is highly dependent on load, road conditions, and tire maintenance. While robust, owners should budget for mid-life failures in electronics and sensors on older vans. Ultimately, proactive maintenance, understanding the specific demands of diesel engines and their aftertreatment systems, and addressing sensor-related warnings promptly are key to cost-effective ownership of any Mercedes-Benz Sprinter.
