2013 – 2021

The first all-aluminium Range Rover. The modern collectible.

Overview

L405 at a glance

Key facts

Body styles: SWB & LWB
Units built: ≈ 350,000
Collector picks: 2017+ facelift, SVAutobiography, Fifty edition
Values (2025): $35k – $180k+

Common symptoms

Air suspension leaks
Front bags typically go first around 60–100k mi. Symptoms: overnight sag, compressor running long.
Timing chain wear (3.0 TDV6)
Rear-mounted chain wear on early builds — listen for cold-start rattle.
Coolant crossover pipe (5.0 S/C)
Same weak point as the L322 5.0. Plan on it if not already done.
Infotainment glitches
Touch Pro / Touch Pro Duo lockups — software updates and battery voltage matter.
Rear diff pinion seal
Weeping seal is common. Not urgent, but should be watched.

Issues

Common problems & troubleshooting

The failures owners of the L405 actually see, with the symptoms to look for and the steps to work through them. Reference only — complex repairs should go to a specialist.

Air-suspension front bag leak

Symptoms: Car sits nose-down overnight, compressor runs longer than usual on start-up, ride-height warning.
Likely causes: Front bags typically fail first around 60–100k mi; a slow perforation at the top fold.

Troubleshooting steps

1.Raise the vehicle to access-height, then soap-spray each bag to find leaks.
2.If a bag is leaking, replace both fronts (or both rears) together as a pair.
3.Inspect the compressor's runtime — a tired compressor often follows a leaking bag.
4.Recalibrate ride height with a capable scan tool after replacement.

3.0 TDV6 timing chain wear

Symptoms: Diesel rattle on cold start (2–10 s), rough idle when warm, P0016/P0017 correlation codes.
Likely causes: Rear-mounted timing chain and tensioners stretch on early builds, especially with extended oil intervals.

Troubleshooting steps

1.Confirm with a cold-start audio recording and live cam/crank correlation.
2.Do NOT keep driving — a snapped chain destroys the engine.
3.Full timing job requires engine-out or gearbox-out access; budget accordingly.
4.Switch to 8,000 mi / annual oil changes with LR-spec low-SAPS oil afterward.

5.0 supercharged coolant crossover pipe

Symptoms: Sweet smell, gradual coolant loss, no visible external drip.
Likely causes: Same plastic crossover pipe design as the L322 5.0 — brittle with heat cycles.

Troubleshooting steps

1.Pressure-test the cooling system and inspect under the supercharger.
2.Combine with a timing-chain-guide job — the labour overlap is huge.
3.Fit the updated metal crossover pipe.
4.Bleed the cooling system properly; airlocks cause repeat overheats.

Touch Pro / Touch Pro Duo infotainment lockups

Symptoms: Black screen, frozen rotary controls, reversing camera won't display, phantom reboots.
Likely causes: Firmware bugs, weak 12 V battery causing voltage sags, or a failing InControl module.

Troubleshooting steps

1.Load-test the 12 V battery first — voltage sags cause 80% of infotainment glitches.
2.Perform a hard reset: hold volume + home for 10 seconds.
3.Check for and apply the latest InControl / IVI software update at a franchised dealer.
4.If problems persist after a battery + software update, the head unit is the next step.

Rear differential pinion seal leak

Symptoms: Oil weep at the front of the rear diff, drips on the driveway aft of the transfer case.
Likely causes: Pinion seal hardens with age; sometimes a worn pinion bearing accelerates it.

Troubleshooting steps

1.Clean the diff nose, drive 100 miles, and re-inspect to confirm the leak source.
2.Check pinion-flange play by hand — any movement means bearings, not just a seal.
3.Seal-only job: mark the pinion nut, torque count on removal, and reinstall to the same preload.
4.If bearings are worn, do a full pinion rebuild — otherwise the new seal will leak again.

History

The story

The L405 was Land Rover's most significant leap in a generation. The D7u aluminium platform shed 420 kg, sharpened dynamics, and let the interior grow without the car growing in kind.

Introduced in 2012 as a 2013 model, the L405 brought all-aluminium construction, a fully modern cabin, and eventually the SVAutobiography's 565-hp supercharged send-off.

The 2017 facelift is the enthusiast's sweet spot — modernized cabin, pre-emissions-tightening simplicity, and interior tech that still holds up.

Production ended in 2021 with the arrival of the L460. The L405 is the current focus of the club's parts, issues, and manuals archive.

Powertrains

Engine family

3.0 TDV6 diesel

2013 – 2020

254 hp / 600 Nm

Timing chain wear on early builds; regular oil changes are non-negotiable.

4.4 SDV8 diesel

2013 – 2018

339 hp / 740 Nm

The long-distance choice. Watch for oil cooler seepage and EGR issues.

5.0 V8 Supercharged

2013 – 2021

510 – 565 hp

The collector engine. Timing chain guides and coolant crossover pipe are the known items.

2.0 P400e PHEV

2019 – 2021

398 hp combined

High-voltage battery health matters more than mileage.
