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.

Variant History & Key Milestones

2012 - AJ133P (510 PS) introduced with 625 Nm torque, marking the launch of the L405 generation and replacing the previous L322’s 5.0L supercharged unit with improved efficiency and power density.

2017 - AJ133P (550 PS) calibrated for SVAutobiography Dynamic, increasing power to 404 kW and torque to 680 Nm for enhanced performance in the flagship SV trim.

2019 - AJ133P (565 PS) uprated for SVAutobiography LWB and Dynamic models, delivering 557 bhp and maintaining 680 Nm torque to compete with emerging high-performance luxury SUVs.

Present - Still in production, with the 5.0L Supercharged V8 remaining the top-tier petrol option for the L405 LWB alongside diesel and mild-hybrid six-cylinder alternatives.

Timing Chain Tensioner & Guide Failure

Why Range Rover L405 LWB 5.0 Supercharged AJ133 Engines Fail

-> Compare rebuilt AJ133 engine prices for your Range Rover L405 LWB 5.0 Supercharged

Affected Models

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 Cost Guide

UK repair routes at a glance

Minor Repair - Early tensioner replacement

Dealer

Specialist

£1,200-£1,650

Preventative fix; 40,000-60,000 mile extension if caught before guide damage

Major Repair - Full timing system overhaul

Dealer

£4,200-£5,800 (estimated based on standard UK dealer rates)

Specialist

£2,800-£3,900

Full Replacement - Rebuilt AJ133 Engine

Best Value

Dealer

£9,500-£12,500 (estimated based on standard UK dealer rates)

Specialist

£6,400-£7,500

Complete stripped block rebuild with upgraded timing components, new bearings/seals, bench-tested, ECU-matched, 12-month warranty. Workshop-fitted.

Permanent solution when chain jump has caused piston/valve damage

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.

FAQs

Range Rover L405 LWB 5.0 Supercharged Engine ReplacementFrequently Asked Questions

Everything Range Rover L405 LWB 5.0 Supercharged owners usually ask before choosing a rebuilt, reconditioned or used replacement engine.

Question 1

What are the warning signs of timing chain failure on a Range Rover L405 LWB 5.0 Supercharged?

Listen for a brief metallic rattle on cold start that disappears after 2-3 seconds; this indicates tensioner wear before catastrophic failure occurs on your Range Rover L405 LWB 5.0 Supercharged.

Key points

  • • Cold-start rattling lasting under 3 seconds suggests early tensioner wear
  • • Cam/crank synchronisation fault codes appear once guides are damaged
  • • Metallic rattling that persists after warm-up means stop driving immediately
  • • Oil analysis can detect aluminium particles from worn chain guides
Important

Continuing to drive with persistent chain rattling risks piston/valve damage requiring full engine replacement.

Question 2

Should I choose used, reconditioned, or rebuilt for my Range Rover L405 LWB 5.0 Supercharged engine replacement?

Rebuilt AJ133 engines offer the best balance of reliability and value for Range Rover L405 LWB 5.0 Supercharged owners, with upgraded components addressing known failure points.

Key points

  • • Used engines carry unknown mileage and hidden wear risks
  • • Reconditioned units replace visible wear parts but may miss internal issues
  • • Rebuilt engines include full strip, upgraded components, and bench testing
  • • All EngineMarket suppliers provide minimum 12-month unlimited mileage warranty
Important

Avoid used engines without compression test reports - hidden bearing wear can cause repeat failure within months.

Question 4

Will a rebuilt engine affect my Range Rover L405 LWB 5.0 Supercharged warranty or insurance?

A professionally rebuilt AJ133 engine with warranty documentation does not invalidate your Range Rover L405 LWB 5.0 Supercharged insurance; always declare the replacement to your provider.

Key points

  • • Insurance requires declaration of major mechanical changes
  • • Rebuilt engines with 12-month warranty satisfy most insurer requirements
  • • Keep all invoices and warranty certificates for future claims

-> Get insurance-ready documentation with your Range Rover L405 LWB 5.0 Supercharged engine quote

Question 5

Can I drive my Range Rover L405 LWB 5.0 Supercharged if the engine is knocking?

No - stop driving immediately if your Range Rover L405 LWB 5.0 Supercharged engine produces metallic knocking to prevent catastrophic crankshaft damage.

Key points

  • • Metallic knocking indicates bearing failure or piston contact
  • • Continuing to drive circulates metal debris through oil galleries
  • • Arrange recovery to a specialist workshop, do not attempt to drive
  • • Early diagnosis can sometimes save the block for rebuild
Important

Driving with knocking can turn a £6,500 rebuild into a £12,000+ replacement due to irreparable block damage.
