Summary Verdict

The 2008 Mercedes-Benz Sprinter is a capable workhorse with a generally good reliability record, particularly for its diesel engines. However, owners should be aware of potential issues such as glow plug and turbocharger problems in the OM646 and OM642 diesel engines, respectively. Transmission issues, while not rampant, can include fluid leaks and torque converter problems. Suspension components like leaf springs can wear over time, and electrical gremlins, such as window regulators and various sensors, are not uncommon. Exterior rust can be a concern in certain environments. Overall, proactive maintenance and addressing these specific potential issues can ensure the continued serviceability of the 2008 Sprinter.
