Summary Verdict

The 2005 Mercedes-Benz Multego, while a capable commercial vehicle, presents a mixed reliability profile. The diesel engines, particularly the CDI variants, are generally strong but can be prone to issues like glow plug failures, turbocharger problems, and injector issues, especially with high mileage. Automatic transmissions, while robust, can suffer from fluid leaks and electronic component failures. Suspension components, particularly if equipped with air suspension, require attention to prevent leaks and wear. Electrical gremlins, often related to the Body Control Module, can manifest as intermittent faults. Exterior corrosion is a concern, as is the common issue of headlight lens clouding. Interior components like the HVAC blower motor can also fail. Regular, diligent maintenance is paramount for mitigating these potential issues and ensuring the longevity of the Multego.
