This guide empowers M-Class owners to navigate their vehicle's needs while minimizing potential pitfalls.
Common issues with the W166 M-Class include oil leaks (especially around the engine and transmission), particularly with the turbo charged engines, suspension wear (including air suspension components, if equipped), issues with the electronic stability control system, and failures with the infotainment system. Turbo issues are common if servicing has been neglected and the correct oils are not used.
WOF tips
During a WOF inspection, the focus will be on the condition of the tires, brakes, lights, and suspension components. Pay close attention to any signs of wear or damage to the suspension, particularly the air suspension (if fitted). Also, ensure that all lights are functioning correctly and that there are no warning lights illuminated on the dashboard. Often the rear tail lights are the first to suffer failure with the globes failing causing WOF failure.
