Disadvantages of the Mercedes M160 engine
- The engine has a modest life, and oil consumption often appears before 100,000 km; if it is ignored for long, the valves burn;
- The timing chain may need attention as early as 50,000-80,000 km;
- The turbocharger and exhaust manifold are not very durable either;
- Do not save on oil, otherwise the crankcase ventilation clogs quickly.
