Land Rover Discovery 3 Parts

What this collection covers

The Discovery 3 (internal code L319) was produced from 2004 to 2009 and sold in North America as the LR3. It replaced the Discovery Series II and introduced a new Integrated Body Frame platform shared with the Range Rover Sport L320. In EU markets the dominant engine was the 2.7 TDV6 diesel (engine code 276DT), producing 190 PS. The 4.4 V8 petrol (engine code 448PN) was available as an alternative in lower volumes.

This collection covers replacement parts for the L319 generation. Some parts are shared across generations. Where fitment spans multiple generations, product descriptions state this clearly.

Parts available in this collection include: air suspension components, propshaft and driveline parts, engine service parts, EGR system components, brake system parts, cooling system components, chassis hardware, interior trim fasteners, and drivetrain seals and gaskets.

Engine variants and fitment

Confirming your engine variant before ordering is important, as the 2.7 TDV6 and 4.4 V8 have different requirements for many components including cooling, intake, and drivetrain parts.

The two main configurations in EU-market Discovery 3 vehicles are:

• 2.7 TDV6 diesel (276DT): the primary EU-market engine, introduced with a timing belt service interval. A six-speed ZF automatic or six-speed ZF manual transmission was available depending on specification.
• 4.4 V8 petrol (448PN): fitted to a smaller portion of the EU fleet, with different cooling and intake requirements.

A minority of vehicles received the 4.0 V6 Cologne petrol engine (406PN), available in certain markets including Europe in lower volumes.

If you are unsure which engine or specification your vehicle carries, your VIN (Vehicle Identification Number) is the most reliable reference. Budget Parts offers a parts catalogue reference page and a contact option for fitment queries before ordering.

High-demand part categories for the Discovery 3

The following categories account for a consistently high proportion of orders for the L319 generation. This reflects the known wear profile of the model across its age and typical mileage range in the EU fleet.

Air suspension components are among the most ordered parts for the Discovery 3. The Electronic Air Suspension (EAS) system fitted to higher-trim L319 vehicles uses an air compressor, air springs (airbags), and height sensors. These components have a finite service life, and age-related degradation is common in vehicles now 15 to 20 years old. Both full air suspension service kits and individual replacement components are available.

Propshaft and driveline parts are a frequent requirement on higher-mileage Discovery 3 vehicles. The centre bearing, universal joints, and differential output seals are the most commonly replaced driveline components on this generation.

EGR system components including EGR valves, EGR coolers, and related gaskets are a regular service requirement for the 2.7 TDV6 diesel. Intercooler hoses and boost pipe components are also stocked for this engine.

Engine service parts for the 2.7 TDV6 include timing belt kits, water pump components, thermostat and housing assemblies, oil seals, and gasket sets. The 2.7 TDV6 uses a timing belt (not a chain), and this is a scheduled replacement item. The timing belt service guide for this engine is linked in the Technical Guides section below.

Brake system parts including discs, pads, caliper components, and brake line hardware are held in stock for the L319. As a heavy SUV with a kerb weight in the region of 2,400 to 2,540 kg depending on engine and specification, the Discovery 3 places significant demand on its braking system.

Chassis hardware including fasteners, mounting hardware, and suspension arm components rounds out the most frequently ordered categories for this generation.

Using your VIN to confirm fitment

The Discovery 3 was built across several model year variants and trim grades. Some parts are specific to model year, engine variant, or trim specification. If you have any doubt about fitment, use your VIN before ordering.

Your VIN is a 17-character code found on the driver's door frame (LHD or RHD depending on market variant), on the dashboard visible through the windscreen, and on your vehicle registration document. The VIN encodes the model year, engine code, and build specification. The Budget Parts parts catalogue page provides VIN-based reference support, and the contact page is available for fitment queries.
