For those considering a robust and capable van, the 2011 Mercedes Van, particularly the Sprinter model, often comes into the conversation. While not my primary focus, my extensive experience with a 2012 Mercedes Sprinter work van offers valuable insights into the realities of owning and operating these vehicles, especially for potential buyers in the used market. Having logged significant mileage and dealt with its share of challenges, I can provide a grounded perspective for anyone looking into a similar model year.
The Strong Points: Driving Dynamics and Capability
One aspect that consistently impressed me about the Sprinter was its driving experience. Even when heavily loaded, this van delivered ample power and maintained composure on the road. My 2012 model, a single rear wheel (SRW) configuration, regularly carried around 11,000 lbs of tools and materials. Furthermore, it frequently towed a trailer with a 26-foot scissor lift, pushing the combined weight close to 20,000 lbs. Despite this significant load, the van handled admirably, comfortably cruising at 80 mph on interstate highways. The robust engine and chassis provided a level of performance that belied its utilitarian nature.
Addressing the Drawbacks: Reliability and Emission System Issues
However, ownership wasn’t without its hurdles. After the 100,000-mile mark, my Sprinter began experiencing a series of recurring and significant issues, primarily related to the emissions system. These problems included failures of the NOx sensor, DEF tank heater, and substantial DEF tank crystallization. Adding to the list were a broken turbocharger – where the compressor wheel sheared off – and EGR valve malfunctions. Each of these incidents resulted in substantial repair bills, ranging in the $5,000 to $8,000 range. It became clear that these complex diesel engines, while powerful, could be susceptible to costly breakdowns, especially concerning their intricate emission control systems.
A notable observation with these Variable Geometry Turbo (VGT) diesel engines is their sensitivity to driving style. “Babying” the engine, or consistently driving at low loads and speeds, can exacerbate issues like carbon buildup and clogging, particularly within the turbocharger and exhaust system. To mitigate this, occasional full-throttle acceleration is recommended to help keep these systems clear and functioning optimally.
The Turning Point: Emission System Deletion
To address the persistent Diesel Particulate Filter (DPF) problems, a decision was made to install a complete “deleted” exhaust system, removing the restrictive emissions components. This modification, coupled with an ECU flash to recalibrate the engine management system, brought about a remarkable improvement in overall performance and reliability. Post-deletion, the van ran significantly better and continued to operate for another 100,000 miles without those recurring emission-related failures. While such modifications might not be legal in all regions or aligned with everyone’s environmental concerns, they undeniably addressed the reliability issues I was experiencing.
Speed Limiter and Conclusion
One final, albeit minor, annoyance was the factory-set speed limiter. Engaging abruptly at 83 mph, it would severely cut throttle until the van slowed below 80 mph. This proved particularly frustrating when attempting to overtake vehicles. Fortunately, the ECU flash, implemented for the emission system delete, also removed this speed limiter, resolving this issue.
In conclusion, reflecting on my experience with a similar Mercedes van, the 2011 Mercedes Van Sprinter offers a compelling blend of performance and capability, especially for demanding tasks. However, potential owners should be aware of the potential for emission system related issues, particularly as these vehicles age and accumulate mileage. Despite these challenges, the overall driving experience and robustness of the van were undeniable, and I would seriously consider owning another, perhaps even converting one into a moto camper.
