Most engine problems are related to failures of the electronically-controlled VP44 fuel injection pump. There are numerous cases described online, where the modern hollow camshafts would break. This engine is also prone to oil leaks, especially from under the valve cover. With high mileage, the turbocharger geometry or the viscous coupler bearing often seize up. Poor-quality oil quickly damages the hydraulic lifters and the pressure reduction valves.
