2023 Mercedes-benz Sprinter 3500 problems

Common 2023 Mercedes-benz Sprinter 3500 problems

The 2023 Mercedes-Benz Sprinter 3500 is a popular and dependable van, but like all vehicles, it can have issues that affect its performance and reliability. Here are some common problems reported by owners of this model:

• Faulty DEF Heater: In the 2020 model and newer Sprinters, a faulty DEF heater is a common issue, especially in colder climates. The heater element can burn out, causing the engine light to come on and potentially leading to an active start countdown.

• Broken Exhaust Flex Pipe: The exhaust flex pipe is a common issue in the 2007 or 906 chassis with the V6 OM642 diesel engine. Leaks from the exhaust, coming from the flex pipe, can melt the nearby wiring, causing the engine to shut off, not restart, and start the counter.

• No Start Count Down Dep-Counter: The Sprinter 2010 and newer models with Bluetec have a no start count down Dep-Counter that starts counting down any remaining start cycles if there are issues with the DEF level or the Nox sensors and other components related to the DEF/Adblue.

• A Clogged DPF: The Sprinter's DPF, or Diesel Particular Filter, grabs soot from the exhaust to prevent black smoke from leaving the exhaust. If the DPF becomes clogged, it can restrict exhaust flow and cause the van to lose power as the clogging increases.

• Reduced Power / Limp Mode: The Sprinter has a Limp Mode, which is a safety feature to protect the engine from damage. If the engine is pushed too hard, the Limp Mode can be activated, causing the van to lower engine power to prevent further damage to affected components.

• Oil Cooler Leaks: Oil cooler leaks are common in the 2007 to present models with the OM642 engine. The oil cooler seals are where most of the engine oil leaks take place. As of late, Mercedes has updated the seals with a better material made from Viton, which increases their life.

• Glow Plug Problems: Just like all diesel engines, the glow plugs and modules in the Sprinter will not last forever. Sometimes the plugs will break off in the cylinder head, requiring a special tool to drill out and extract the glow plug without removing the cylinder head.

• Injector Issue or Black Death: Another problem usually called "Black Death" is the copper seal ring located in the middle of the injectors. If the copper seal ring deteriorates, combustion gasses can escape, causing black tar and coal-like material to accumulate over the fuel injectors.

These are some of the most common problems reported by owners of the 2023 Mercedes-Benz Sprinter 3500. It is important to note that not all vehicles will experience these issues, and some may experience different problems altogether. Regular maintenance and timely repairs can help prevent or address these issues, ensuring that the Sprinter 3500 remains a reliable and dependable workhorse for years to come.
