Land Rover Discovery II 1999–2003 Workshop Manual (P/N VDR 100330 NAS (6))

This 1529-page OEM publication (part number VDR 100330 NAS) serves as the definitive reference for servicing the Land Rover Discovery 2. Whether you are running diagnostics in a professional bay or tackling a major rebuild at home, this PDF manual delivers the exact factory specifications required for accurate assessments.

• Covers V8 gasoline and Td5 diesel engine configurations, transmissions, and body trim.
• Features high-resolution, zoomable exploded-view diagrams that retain print-quality clarity for complex assemblies.
• Provides essential maintenance schedules, full wiring diagrams, and accurate repair procedures.
• Details the LT230SE transfer box, SLABS ECU, Bosch Motronic 5.2.1 engine management, EVAP emission control, and SRS restraint systems.

Instead of outsourcing labor, this documentation equips your bay with the step-by-step procedures needed to tackle intensive tasks in-house, such as overhauling the LT230SE transfer box, bleeding the Active Cornering Enhancement (ACE) hydraulic circuit, or calibrating the SLS height sensors.

Mechanical and Electrical Systems Documentation

The resource provides exhaustive breakdowns of major vehicle components. It details the operational parameters for both powerplants, alongside the R380 manual gearbox and ZF4HP22/24 automatic transmissions. Documentation extends through the transfer box and axle assemblies, offering a clear view of the vehicle's drivetrain architecture. Visualizing these internal mechanisms is straightforward thanks to specific visual aids, including the R380 gearbox cross section, brake system control diagram, SRS block diagram, and the evaporative emission system component layout.

Modern workshop environments require deep insights into complex electronic systems. This file covers the management modules governing engine output, anti-lock braking, Active Cornering Enhancement (ACE), and Self Levelling Suspension (SLS). Always verify proper safety protocols and consult a certified technician before initiating heavy mechanical service or electrical testing on these active dynamic systems, especially when handling pyrotechnic SRS components or high-pressure hydraulics.

Critical Specifications for the Bay

Technical data is laid out cleanly to maximize your efficiency during inspections. You will find rigorous torque values for chassis and engine components, such as the V8 flywheel-to-crankshaft specification set at 78 Nm. It also logs vital capacities, noting the 25.5-gallon fuel tank, and establishes baseline operating metrics like the 100 °C cooling system threshold. For accurate troubleshooting, the manual lists precise sensor reference values and diagnostic thresholds, ensuring you have the exact data needed to verify system integrity and efficiently return the vehicle to the road.

When servicing the Discovery Series II, technicians must navigate specific model pitfalls. For example, the notorious "Three Amigos" dash warning lights often trace back to ABS modulator shuttle valve failures rather than complete system crashes. Additionally, the front double-cardan propeller shaft sits exceptionally close to the catalytic converter; if the grease dries out from radiant heat, a fractured joint can cause catastrophic transmission casing damage.
