Character
N62
"Valve stem seal failure (30%+ by 160k km). Coolant transfer pipe leak = 40+ hours labour. Timing chain guide brittleness. Over-engineered with too many failure points. Beautiful power, terrible ownership."
M57
"Legendary diesel six. Powered E46 330d to E90 335d. Smooth, torquey, reliable. Swirl flaps and turbo actuator at high mileage."
