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 NA in the Range Rover L405: rare combination
The naturally aspirated V8 in the L405 is barely found on the market — and whoever finds one experiences something special. No boost characteristics, just direct V8 response in a modern vehicle. Equally attractive to collectors and enthusiasts.
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 7
Air springs tear and the compressor overloads. Typical case: vehicle drops after parking, compressor and both air springs plus valve block replaced (approx. 2,200 euros). Occurs regularly despite the aluminium body.
Panoramic roof drain hoses corrode at the plastic connector fitting and break off. Water runs through the body to the audio amplifier under the driver's seat. Several vehicles written off. Annual cleaning of the drains strongly recommended.
Water ingress through failed sunroof drains or leaking windows damages control units under the front seats. Multiple ECUs affected simultaneously. Audio amplifier under the driver's seat particularly vulnerable. Total losses documented by insurance in confirmed cases.
Tailgate seal and gaskets around the rear lights leak — water collects in the spare wheel well. Water runs out when opening the tailgate after rain. Seals and light strip sealing must be replaced.
Rear brake calipers seize due to corrosion of the guide pins in the aluminium housing. Vehicle pulls to one side under braking. Regular replacement necessary. Disc life reduced to approximately 50,000 km by the binding effect.
ZF 8HP gearbox suffers harsh shifts, delayed engagement and torque converter issues when oil changes are skipped. Gearbox oil change recommended every 60,000 km. Sensor fails to detect park position. Diesel variants particularly affected.
InControl Touch Pro navigation uses TMC-based traffic data and suggests partly nonsensical routes. System freezes and restarts. Bluetooth issues and display pixel failures known. Updates improve things but do not resolve them permanently.
