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

Air suspension compressor and air springs fail regularly. Vehicle drops after parking, compressor runs continuously. Valve block, height sensors and reservoir tank also affected. Replacing one air spring costs over 1,500 euros.

Panoramic roof drain hoses corrode at the connector fitting and break off. Rainwater runs uncontrolled into the body, collects under the driver's seat and damages the audio amplifier and ECUs. Several vehicles written off.

Door lock module defective — doors can open unintentionally while driving. Land Rover recall for over 65,000 vehicles (2014–2016). Sealed unit must be completely replaced; no partial repair possible.

Brake discs warp prematurely due to the vehicle's high mass. Brembo calipers with steel guide pins in aluminium housings corrode and seize. Average disc life approximately 50,000 km. ECU-controlled pistons require specialist diagnostics.

Diesels from 2016 with AdBlue/SCR systems show excessive consumption and sensitive NOx sensors. Overfilling damages the sensor. Vehicle immobilises itself when AdBlue tank is empty. Fault diagnosis starts at 75 euros.

Front lower wishbones (straight and curved variants) wear early due to vehicle weight. Bushings are barely possible to press in correctly — full arm replacement recommended. Wheel alignment essential after repair.

The most common cause of the SRS warning light is a broken wire in the thin cables under the front seats. Land Rover solution: overlay cable repair. Cheaper than replacing the control unit. Simple OBD diagnosis is sufficient to narrow down the fault.
