Land Rover Range Rover Sport
Solid 5.0-litre V8 (naturally aspirated, no supercharger). Timing chain and guides are the known weak point from around 130,000 km. Short oil change intervals (max. 8,000 km) significantly reduce the risk. Replace plastic coolant pipes preventively with aluminium items. Character: refined V8 with decent power delivery.
5.0 V8 Sport L320: naturally aspirated, naturally great
The 5.0-litre naturally aspirated V8 needs no supercharger to impress. 276 kW with a smooth V8 note, no turbo lag, no artificial boost. In the Range Rover Sport L320 that is an honest sports car experience from Britain — as long as the timing chain holds.
Engine Weaknesses 4
The AJ133 5.0L V8 (naturally aspirated) is known for premature wear of the plastic timing chain guides and hydraulic tensioners. The fault typically appears from 120,000–150,000 km. Extended oil change intervals are a frequent contributing factor.
Symptoms: Rattling/knocking on cold start, P0008/P0016/P0017, engine light, power loss
Like the supercharged V8, the naturally aspirated V8 has numerous plastic coolant pipes and fittings that become brittle and crack. Pre-emptive replacement with metal pipes (Euro AMP kit) is strongly recommended.
Symptoms: Sudden coolant loss, overheating warning, steam from the engine bay
Ignition coils on the 5.0 V8 tend to fail, often in combination with oil-fouled spark plugs (caused by valve stem seals). Rough running and misfire codes on multiple cylinders simultaneously are typical.
Symptoms: Rough running, P030X misfire codes, engine light, oil-fouled spark plugs
Valve stem seals on the 5.0 V8 (NA) wear out and allow oil into the combustion chamber. Oil-fouled spark plugs and blue smoke on cold start are typical symptoms. Repair requires extensive engine disassembly.
Symptoms: Blue smoke on cold start, oil-fouled spark plugs, elevated oil consumption >0.5L/1000km
Vehicle Weaknesses 8
Rear air springs tear at the base and lose pressure. Vehicle drops to one side or completely after parking. Valve block and height sensors are also typical failure points from approximately 100,000 km.
Vacuum pump fails and cuts brake servo assistance. Vehicle subject to recall. Danger from massively increased brake pedal effort. Leaking brake lines at the front axle also known.
Front lower wishbones and their bushings wear early due to the vehicle's high weight. Knocking and clunking at low speeds and under braking is typical. Full arm replacement recommended.
Electronic parking brake jams after worn brake pads or corroded guides. Fault code C1A00 (control module). Actuator module often needs complete replacement. Mainly affects 2006–2011.
Rear axle differential loses oil from approximately 100,000 km due to ageing seals. Bearing damage threatens if neglected. Oil seepage visible at the differential, often accompanied by a burning oil smell.
Panoramic or sunroof drain hoses block with leaves and debris. Water runs into the cabin and can damage ECUs under the seats. Typical on 2005–2009 models.
Door lock mechanism defective — doors cannot be correctly locked or unlocked. Sealed unit must be completely replaced. Recall issued for unintended opening while driving on certain model years.
Facelift models from 2010 onward show increased battery faults due to higher electrical loads. Pixel failures in the instrument cluster display known. Corroded earth points are a common cause of cascading fault messages.
