Land Rover Discovery 4 Parts

Parts for the Land Rover Discovery 4 (L319), produced 2009 to 2016 on the Integrated Body Frame platform shared with the Discovery 3. Covers all EU-market variants from the 2.7 TDV6 to the post-facelift 3.0 SDV6 and 3.0 SCV6 petrol. Genuine, OEM, and aftermarket in stock for same-day EU dispatch.

The Discovery 4 (L319), 2009 to 2016

The Discovery 4 is the second-generation vehicle on the L319 Integrated Body Frame platform, produced from 2009 until the Discovery 5 (L462) took over in 2017. It carries the same chassis code as the Discovery 3 (2004 to 2009) and shares the structural body-on-frame architecture, the rear air suspension layout, and several driveline components. Where parts fit both L319 generations the product listing states so; engine, electrical, and calibration-sensitive components are generally restricted to one generation.

Two distinct production phases apply. Pre-facelift cars (2009 to 2013) launched with the 2.7 TDV6 and the original 3.0 TDV6 / SDV6 variants and the 5.0-litre V8 petrol. The 2014 facelift refreshed the front end, replaced the V8 petrol with the 3.0 SCV6 supercharged petrol, introduced stop-start across the diesel range, and revised the SDV6 calibration. The ZF 8HP70 eight-speed automatic also arrived on the SDV6 from 2012, replacing the earlier ZF 6HP28 six-speed.

The Discovery 3 and the Discovery 5 are the adjacent generations. No L319 parts cross over to the L462, which is built on an entirely different aluminium-intensive platform.

Engine variants in the L319 Discovery 4

2.7 TDV6 (Ford AJD-V6, 2,720 cc, 190 PS): early production only, 2009 to the 2010 model year. Paired with the ZF 6HP26 six-speed automatic or the six-speed manual. Engine architecture is carried over from the Discovery 3, but emissions and calibration differ. Uses a timing belt at the scheduled service interval.

3.0 TDV6 (306DT, 2,993 cc, 211 PS): introduced for the 2011 model year and produced through 2013. Twin-turbo diesel, paired with the ZF 6HP28 six-speed automatic. The 306DT runs a wet belt timing system: the front camshaft drive belt and the rear high-pressure fuel pump belt are both scheduled service items and must be replaced together.

3.0 SDV6 (306DT, 2,993 cc, 245 to 256 PS): available across the full Discovery 4 production run with progressive power increases. Sequential twin-turbo architecture. From 2012 the SDV6 was paired with the ZF 8HP70 eight-speed automatic. Post-2014 facelift SDV6 vehicles received stop-start technology and revised calibration.

5.0 V8 petrol (AJ133, 375 PS): naturally aspirated, available from 2009 to 2013. Lower EU volume but supported in stock for service parts.

3.0 SCV6 petrol (AJ126, 340 PS): supercharged V6, introduced at the 2014 facelift as the replacement for the 5.0 V8. Petrol-specific cooling, intake, and ignition components are not interchangeable with the diesel range.

Kerb weight ranges from 2,396 kg to 2,583 kg across the variants, reflecting the powertrain weight spread. Confirm your engine code via VIN before ordering anything in cooling, timing, intake, or fuel system categories.

Identifying your Discovery 4 by VIN

The L319 chassis code is shared with the Discovery 3, so chassis code alone is not a reliable fitment input. The 17-digit VIN is the authoritative identifier. It is stamped on the driver-side door frame, visible through the windscreen base on a plate, and recorded on the V5C or local registration document. The 10th character identifies model year.

For the Discovery 4 specifically, the VIN model year decode resolves three things at once: which generation the vehicle belongs to (D3 or D4), which engine variant is fitted (2.7 TDV6 limited to 2009-2010, 3.0 TDV6 limited to 2011-2013, SDV6 across the full run), and which transmission specification applies (ZF 6HP28 versus ZF 8HP70 on the SDV6). Pre-facelift versus post-facelift status follows from the model year too: 2014 onward is post-facelift.

Parts categories with consistent demand for the L319

Discovery 4 stock is weighted toward the categories where age and mileage wear are now reaching the EU fleet. Air suspension components, wet belt timing kits, EGR system parts, propshaft and driveline service items, EPB hardware, cooling for the 306DT, and chassis fasteners cover the bulk of routine workshop demand. Each category link below filters results to L319 fitment.

Quality tiers for the Discovery 4

The Discovery 4 is now between nine and seventeen years old, and the parts choices are driven less by warranty considerations than by service life, cost-per-mile, and supply continuity. Genuine, OEM, and aftermarket are all viable depending on the system.

Genuine is the right tier for the EAS air suspension control valves and ride height sensors, the rear differential service kit, the 8HP70 transmission rebuild components, and the wet belt timing kit on the 306DT. These are systems where calibration history, the exact JLR part number, and the original tolerance band matter for long-term reliability and warning code suppression.

For the wet belt kit specifically, Genuine and OEM-equivalent are both acceptable, but the brand-name aftermarket route is not recommended on this engine. The 306DT is unforgiving of incorrect belt tension or material grade, and the failure mode is catastrophic.

OEM covers the practical bulk of Discovery 4 service work. Pierburg supplies EGR valves and coolers. Bosch supplies the diesel high-pressure pumps, injectors, glow plugs, and most sensors. Mahle supplies cooling components. ZF supplies transmission service parts and the Lifeguard 6 / Lifeguard 8 fluids for the 6HP28 and 8HP70. Brembo, ATE, and TRW cover braking. OEM-tier supply is the most cost-effective route for routine service on the L319.

Aftermarket is appropriate for discs and pads, filters, bushings, body fasteners, exterior lighting bulbs, and air suspension service kits that are no longer in Genuine supply. Each listing names the OEM supplier where the source is verified.

EU stock and dispatch for the Discovery 4

L319 parts are stocked in the Netherlands and dispatched the same working day on orders placed before 15:00 CET. Intra-EU shipments carry no customs paperwork or import VAT at the border, with typical transit of 1 to 2 working days to Germany, Belgium, France, and Luxembourg, and 2 to 4 days to Scandinavia, Iberia, Italy, and central Europe. UK orders ship under standard post-Brexit customs procedures with VAT and duties applied on delivery. Workshops servicing multiple Discovery 4 vehicles can request invoiced trade terms.
