Other Faults on This Variant
Timing Belt Failure and Water Pump Failure
CriticalThe 2.2 SD4 Freelander 2 has a timing belt with a 120,000-mile interval but the water pump is driven by the same belt — and water pump failure destroys the belt. This is a common and expensive failure.
Throttle Body / Anti-Shudder Valve Strip
ModerateThe electronic throttle body (anti-shudder valve) strips its internal plastic gears, causing an unpleasant engine shutdown and a warning light.
Rear Differential Pinion Bearing Failure
CriticalA howling or droning noise from the rear of the car is almost always the rear differential pinion bearing failing. This is incredibly common on all Freelander 2s.
