Land Rover Range Rover Sport
5.0-litre V8 Supercharged with excellent performance but well-known weaknesses. Timing chain set replacement is a matter of when, not if. Supercharger coupling and coolant pipes are further cost items. Running costs are substantial — only justifiable with a complete service history and low mileage.
Sport 5.0 SC L320: roaring supercharged Brit
Supercharger whine, V8 sound, 380 kW — the Range Rover Sport 5.0 SC L320 is an icon of automotive excess. Every time full throttle is applied, the engine recalls the era of British nonchalance. Running costs for enthusiasts.
Engine Weaknesses 5
The most critical issue on the 508PS: plastic timing chain guides and hydraulic tensioners fail from around 100,000 km — faster on the supercharged engine due to higher load. Full repair costs €6,000–10,000.
Symptoms: Rattling on cold start (>5s), P0008/P0016/P0017, engine light, power loss
Several plastic coolant pipes (crossover pipes, thermostat housing) behind and under the supercharger become brittle from thermal cycling. Sudden failure often causes engine damage before the driver can react.
Symptoms: Sudden coolant loss, overheating warning, steam, limp mode
The Eaton supercharger torsional coupler — a plastic and metal spring assembly — breaks apart over time. Land Rover issued a TSB. The rattling sounds like gravel inside the supercharger and disappears under higher load.
Symptoms: Rattling from the supercharger at idle (sounds like stones in a blower), decreasing supercharger output
The supercharged AJ133 also suffers from valve stem seal wear. Oil-fouled spark plugs and elevated oil consumption are typical. Replacement should be considered when timing chain repairs are carried out at the same time.
Symptoms: Blue smoke on cold start, oil-fouled spark plugs, oil consumption > 0.5L/1000km
Ignition coils on the 5.0 SC can fail — typically several at once. Poor ignition combined with oil-fouled plugs from valve seal wear accelerates the failure.
Symptoms: Rough running, P030X codes, engine light, hesitation under acceleration
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.
