Variant History

Range Rover L405 LWB 5.0 Supercharged Engine History & Production Timeline

The Range Rover L405 LWB 5.0 Supercharged launched in 2012, powered exclusively by the Jaguar Land Rover AJ133 5.0-litre V8 petrol engine family. This high-performance powertrain debuted with 510 PS (503 bhp) and 625 Nm of torque, establishing the LWB variant as the flagship luxury SUV for global markets. Throughout its production run, the engine architecture remained consistent, though output was increased to 550 PS (542 bhp) and later 565 PS (557 bhp) for the SVAutobiography Dynamic editions introduced in 2017. The variant remains in production today, continuing to offer the naturally aspirated smoothness and supercharged urgency characteristic of the AJ133 platform, despite the industry-wide shift towards electrified powertrains.

Common Problems

Range Rover L405 LWB 5.0 Supercharged Engine Problems What It Costs to Fix & When Replacement Makes Sense

The Range Rover L405 LWB 5.0 Supercharged, powered by the AJ133 V8 engine family (codes RCBW/RCBV), delivers exceptional performance but faces specific high-mileage failure patterns documented across UK owner forums and specialist rebuilders. Every rebuilt Range Rover L405 LWB 5.0 Supercharged engine supplied through EngineMarket includes upgraded failure-point components and a minimum 12-month unlimited mileage warranty. Use this guide to compare repair options and get tailored quotes from certified UK specialists.

Common failure points and repair options

Timing Chain Tensioner & Guide Failure

Affected
Range Rover L405 LWB 5.0 Supercharged Autobiography, SVAutobiography, Vogue SE (2013-2022, AJ133/RCBW)
Typical failure mileage
60,000-95,000 miles
Root cause
The stainless steel pin on the timing chain tensioner wears a groove into the aluminium chain guide, reducing tension and allowing chain slap; this is corroborated across multiple fullfatrr.com and PistonHeads UK forum threads discussing cold-start rattles and cam/crank synchronisation faults.

Repair options

Repair tierDealer priceSpecialist price
Minor Repair - Early tensioner replacement£1,850-£2,450 (estimated based on standard UK dealer rates)£1,200-£1,650
Major Repair - Full timing system overhaul£4,200-£5,800 (estimated based on standard UK dealer rates)£2,800-£3,900
Full Replacement - Rebuilt AJ133 Engine£9,500-£12,500 (estimated based on standard UK dealer rates)£6,400-£7,500
Our recommendation
If you hear a brief rattling noise on cold start but have no engine management lights, a specialist tensioner replacement may prevent catastrophic failure. However, once cam/crank codes appear or metallic rattling persists, the risk of piston damage is high - on a Range Rover L405 LWB 5.0 Supercharged valued at £25,000-£45,000, a rebuilt engine with upgraded components offers better long-term value than repeated major repairs.

Spun Main or Conrod Bearings

Affected
Range Rover L405 LWB 5.0 Supercharged Autobiography, SVAutobiography (2014-2022, AJ133/RCBW)
Typical failure mileage
70,000-110,000 miles
Root cause
Extended oil change intervals combined with high-load driving can lead to oil starvation at the bearings; UK forum reports on DiscoWeb and rangerovers.net describe sudden loss of oil pressure followed by knocking, with oil analysis confirming bearing material in sump.

Repair options

Repair tierDealer priceSpecialist price
Minor Repair - Oil system flush + bearing inspection£850-£1,350 (estimated based on standard UK dealer rates)£550-£900
Major Repair - Bottom-end rebuild£6,200-£8,400 (estimated based on standard UK dealer rates)£4,100-£5,600
Full Replacement - Rebuilt AJ133 Engine£9,500-£12,500 (estimated based on standard UK dealer rates)£6,400-£7,500
Our recommendation
If your Range Rover L405 LWB 5.0 Supercharged shows low oil pressure warnings or metallic knocking, stop driving immediately - continued operation will destroy the crankshaft. For vehicles with over 80,000 miles, a full rebuilt engine with upgraded bearings and oiling components is more cost-effective than a bottom-end rebuild that leaves aged top-end components at risk.

Supercharger Coupling & Bearing Wear

Affected
Range Rover L405 LWB 5.0 Supercharged Vogue, Autobiography, SVAutobiography (2013-2022, AJ133/RCBW)
Typical failure mileage
50,000-90,000 miles
Root cause
The supercharger isolation coupling wears, causing a rhythmic rattling under load; internal bearings can also wear, producing a high-pitched whine - both failure modes are explicitly listed by UK specialist Vogue Technics as common AJ133 issues they routinely repair.

Repair options

Repair tierDealer priceSpecialist price
Minor Repair - Coupling replacement only£1,450-£2,100 (estimated based on standard UK dealer rates)£950-£1,400
Major Repair - Supercharger overhaul£3,200-£4,600 (estimated based on standard UK dealer rates)£2,100-£3,100
Full Replacement - Rebuilt AJ133 Engine£9,500-£12,500 (estimated based on standard UK dealer rates)£6,400-£7,500
Our recommendation
A rhythmic rattling under acceleration that disappears at idle typically indicates coupling wear - address this early to avoid debris entering the intake. If a high-pitched whine is present or boost pressure is low, the supercharger likely needs a full overhaul. For Range Rover L405 LWB 5.0 Supercharged models over 80,000 miles, combining supercharger repair with a full engine rebuild delivers the most reliable long-term outcome.
