Generations Overview Range Rover L405 parts: scope and production phases
The Range Rover L405 is the fourth-generation full-size Range Rover, assembled at Solihull and produced from model year 2013 through to 2022. It succeeded the Range Rover L322 (2002-2012) and was itself replaced by the Range Rover L460 (2022 onwards). It is the first production 4x4 to use an all-aluminium monocoque unibody structure, resulting in a weight reduction of approximately 420 kg compared to the L322. All variants use the ZF 8HP eight-speed automatic transmission and a Magna Steyr DD295 two-speed transfer case with permanent four-wheel drive.
The L405 divides into two clearly distinct technical phases. Parts compatibility, exhaust after-treatment systems, infotainment components, and electrical architecture differ between phases. Ordering by registration year alone is not sufficient. Confirming which phase your vehicle belongs to before selecting engine-specific, after-treatment, or infotainment parts is the most reliable way to avoid incorrect fitment.
Pre-facelift models (MY2013 to 2016) use the 3.0-litre TDV6 diesel (engine code 306DT, no AdBlue or SCR system), the 4.4-litre SDV8 diesel, and the 5.0-litre AJ133 V8 petrol family. The 3.0-litre AJ126 supercharged V6 petrol was added from 2014. Infotainment is InControl Touch, using a MOST optical ring bus architecture.
Post-facelift models (MY2017 to 2022) use the 3.0-litre SDV6 diesel (engine codes 306PS or 306DT-2, fitted with SCR and an AdBlue dosing system), retain the 4.4 SDV8 diesel and V8 petrol, and from MY2019 add the 2.0-litre Ingenium P400e plug-in hybrid. From MY2020, the 3.0-litre Ingenium straight-six MHEV was introduced in petrol variants. Infotainment moves to InControl Touch Pro and Touch Pro Duo, using Ethernet-based HMI architecture rather than the MOST optical ring of the pre-facelift models.
Parts that are correct for a 2015 TDV6 will not necessarily fit a 2019 SDV6. EGR components, DPF sensors, NOx sensors, AdBlue dosing pumps, and exhaust after-treatment parts are phase-specific. Infotainment components and door modules are also architecture-specific between the two phases.
Powertrain and technical phase reference
Use the table below to identify which phase your L405 belongs to before selecting phase-specific parts.
| Phase | Model Years | Diesel Engine | Petrol Engines | AdBlue | Infotainment |
| Pre-facelift | 2013 to 2016 | 3.0 TDV6 (306DT), 4.4 SDV8 | 5.0 AJ133 V8, 3.0 AJ126 S/C V6 (from 2014) | No | InControl Touch, MOST optical ring |
| Post-facelift | 2017 to 2022 | 3.0 SDV6 (306PS / 306DT-2), 4.4 SDV8 | 5.0 AJ133 V8, 2.0 Ingenium P400e PHEV (from 2019), 3.0 Ingenium MHEV I6 (from 2020) | Yes (SDV6 only) | InControl Touch Pro / Touch Pro Duo, Ethernet HMI |
Note The 4.4 SDV8 diesel and 5.0-litre V8 petrol family are available across both phases. The 4.4 SDV8 does not use an AdBlue or SCR system on the L405 regardless of model year. The 2017 model year is a bridge year in the EU market for infotainment architecture; build date determines which system is fitted.
Vehicle Identification Confirming your L405 variant before you order
The L405 spans a significant powertrain and electronics transition. For most part categories, registration year is sufficient to confirm fitment. For engine-specific components, exhaust after-treatment parts, and infotainment modules, the phase boundary matters more than the year alone.
The 2017 model year requires particular attention. In the EU market, 2017 is a bridge year: some 2017-registered vehicles carry post-facelift infotainment electronics (InControl Touch Pro with Ethernet HMI) but pre-facelift exterior styling. For infotainment and interior trim parts, 2017 vehicles may fall into either specification depending on build date. Your VIN and build date are the most reliable identifiers.
The 17-digit Vehicle Identification Number is the definitive reference. It appears in three locations on every L405: behind the windscreen on the dashboard plate, on the B-pillar door label, and on the V5C registration document. Position 10 of the VIN identifies the model year; positions 4 through 8 encode the vehicle descriptor section, which a JLR dealer or workshop tool can decode to confirm engine family, transmission, drive type, and AdBlue specification. For phase-critical parts, decode the VIN before ordering rather than relying on the registration year.
The L405 shares the JLR D7u aluminium platform with the Range Rover Sport L494 (2014-2022). Some mechanical components in the transmission, air suspension, and drivetrain categories cross-fit between the two, but the vehicles have different body structures and wheelbase dimensions. Always confirm by part number against your L405 VIN before ordering; do not assume universal cross-fitment between L405 and L494.
If you manage a workshop and need fitment confirmation across several L405 variants in a single order, send the relevant VINs to the Budget Parts technical team for pre-order validation.
Parts Categories Parts categories in this collection
The L405 collection covers replacement and maintenance parts for both technical phases. Categories stocked include engine components (gaskets, seals, EGR components, injector seals, cooling system parts), exhaust after-treatment parts (DPF sensors, NOx sensors, AdBlue dosing components for post-facelift SDV6 variants only), transmission service items (ZF 8HP filter kits, fluid, solenoids), air suspension components, braking system parts (discs, pads, calipers, sensors), steering and suspension components (front upper and lower wishbone arms, bushes, ball joints, hub units, anti-roll bar parts), drivetrain and propshaft components, electrical parts (door modules, sensors, relays, switches), cooling system parts, body and trim components, and fuel system parts.
Air suspension parts are among the most frequently replaced components on the L405. The electronic air suspension uses four corner-mounted air strut units, four rotary height sensors, and a dedicated EAS ECU. The OEM air suspension compressor for the L405 is supplied by AMK. Two production variants exist, referenced under part numbers LR088859 and LR108984. The correct replacement unit should be confirmed against your vehicle's VIN or the label on the existing compressor before ordering. EAS calibration is required after compressor, air strut, or height sensor replacement, and the EAS dryer integrated into the compressor assembly must be replaced at the same time as the compressor unit.
Quality Tiers Genuine, OEM and aftermarket parts for the L405
L405 listings show a quality grade on every line: Genuine (original Land Rover-channel stock, full LR part number and packaging), OEM (the same component direct from the original supplier — for example AMK air suspension compressors — without the JLR channel markup), or Aftermarket (an independently manufactured equivalent, with quality varying by supplier). Choose the tier that matches the repair: Genuine for warranty work or original-spec rebuilds, OEM for cost-effective rebuilds where original supplier identity matters, Aftermarket for older vehicles or non-critical items. The Range Rover parts collection carries the full tier definitions.

Driveshaft and driveline problems → What years does the Range Rover L405 cover?
The Range Rover L405 covers model years 2013 to 2022. Production began at Land Rover's Solihull plant with deliveries of the first 2013 model year vehicles in late 2012. Final L405 production ran through 2022, with the fifth-generation L460 succeeding it. This collection covers replacement parts for all L405 model years from 2013 to 2022.
Does my Range Rover L405 have AdBlue?
This depends on your model year and engine. Pre-facelift L405 diesel models from 2013 to 2016 fitted with the 3.0-litre TDV6 (engine code 306DT) do not have an AdBlue or SCR system. AdBlue applies only to post-facelift L405 models from model year 2017 onwards fitted with the 3.0-litre SDV6 (engine codes 306PS or 306DT-2). The 4.4-litre SDV8 diesel does not use AdBlue on the L405 regardless of model year. If you are unsure whether your vehicle has AdBlue, check your engine code or confirm via your VIN.
How do I know which engine my L405 has?
The L405 uses different engines depending on model year and market. Pre-facelift models (2013 to 2016) use the 3.0-litre TDV6 (engine code 306DT) or 4.4-litre SDV8 diesel, and the 5.0-litre AJ133 V8 or 3.0-litre AJ126 supercharged V6 petrol (the V6 petrol was added from 2014). Post-facelift models (2017 to 2022) use the 3.0-litre SDV6 (engine codes 306PS or 306DT-2) with AdBlue, and from 2019 added the 2.0-litre Ingenium P400e plug-in hybrid. From model year 2020, the 3.0-litre Ingenium straight-six MHEV petrol was introduced. Your engine code is stamped on the engine plate. Your VIN confirms your exact build specification.
Do pre-facelift and post-facelift L405 parts differ?
Yes, significantly. Engine-specific components, exhaust after-treatment parts (DPF sensors, NOx sensors, AdBlue dosing pumps), and infotainment modules are not interchangeable between the two phases. Pre-facelift models use a MOST optical ring bus for infotainment. Post-facelift models use Ethernet-based HMI architecture. Door modules and infotainment components must match the correct architecture. For parts that are shared across both phases, such as braking system components, ZF 8HP transmission service parts, and many suspension items, registration year is sufficient for fitment confirmation.
What is the OEM air suspension compressor for the L405?
The OEM air suspension compressor for the Range Rover L405 is supplied by AMK. Two production variants exist, referenced under part numbers LR088859 and LR108984. The correct replacement unit should be confirmed against your vehicle's VIN or the label on the existing compressor before ordering, as the applicable variant depends on production specification rather than a fixed model year boundary. Replacement compressors should match the AMK specification of the original unit. EAS calibration using a JLR-capable diagnostic tool is required after compressor replacement, and the EAS dryer integrated into the compressor assembly must be replaced at the same time.
I have a 2017 L405. Which phase parts do I need?
The 2017 model year is a bridge year on the L405 in the EU market and you cannot determine fitment from registration year alone for three key categories. First, engine and after-treatment parts: if your engine is the 3.0 SDV6 (306PS or 306DT-2), AdBlue and SCR parts apply; if it is the outgoing 306DT TDV6, they do not. Second, infotainment and HMI parts: some 2017 vehicles carry InControl Touch Pro on the Ethernet HMI architecture, others retain InControl Touch on the MOST optical ring. Third, door modules and BCM-adjacent electronics follow the same split. The reliable identifiers are your engine code (on the engine plate) and your VIN build date. Contact the Budget Parts team with your VIN before ordering any of these categories for a 2017 vehicle.
Does the 306DT TDV6 timing chain need replacement on a high-mileage L405?
The 3.0 TDV6 (engine code 306DT, pre-facelift L405 2013 to 2016) and the 3.0 SDV6 (306PS and 306DT-2, post-facelift 2017 to 2022) are timing-chain-driven engines. Land Rover does not specify a fixed chain replacement interval, but tensioner wear, rattle on cold start, and chain stretch become more common beyond 120,000 km, particularly on vehicles with mixed service history or extended oil-change intervals. The full replacement service for these engines is a major workshop operation requiring timing kit (chain, guides, tensioner, sprockets), front cover gasket, sump removal, and post-job VIN coding in some cases. Service parts and timing kits are available in this collection. For diagnostic guidance on the symptoms that indicate timing chain wear on these engines, see the Range Rover L405 problems and fixes guide linked above.
Are Range Rover L405 P400e plug-in hybrid parts available?
Yes. The 2.0-litre Ingenium P400e PHEV was added to the L405 lineup from model year 2019 and ran through to 2022. PHEV-specific parts including hybrid coolant components, charging system parts, high-voltage cables, charge port assemblies, and the 13.1 kWh lithium-ion battery service items are stocked alongside the standard L405 catalogue. Items shared with non-hybrid L405 variants (suspension components, brakes, body parts, interior trim) are interchangeable, but the 2.0-litre Ingenium engine ancillaries and the hybrid drivetrain components are P400e-specific and not shared with the SDV6 or V8 variants. Always confirm via VIN when ordering for a P400e.
What is the difference between the L405 and the Range Rover L460?
The L405 is the fourth-generation Range Rover, produced from 2013 to 2022. The L460 is the current fifth generation, launched from 2022 onwards. The two share no platform architecture. The L460 is built on the MLA-Flex platform and uses Ingenium I6 engines, BMW-sourced V8 units, and P440e and P510e plug-in hybrid variants. Parts for the L405 and L460 are not interchangeable. If you own a 2022 or later full-size Range Rover, confirm whether it is an L405 final-year vehicle or an L460 before ordering. The 2022 calendar year contains both generations depending on build date.
