Td5 Engine Management:
Potential issues with the engine control unit (ECU), injector harnesses, and fuel pump. Head gasket failures are also a known, though not universal, issue, particularly with hard use or lack of proper maintenance.
V8 Engine Issues:
Head gasket failures are common, especially on the 4.6L variants. Inherent issues with the 'GEMS' (Gasoline Engine Management System) and later 'Bosch' engine management systems require careful diagnosis. Coolant leaks, particularly from the 'valley gasket', are also prevalent.
Electronic Air Suspension:
EAS compressor failures, valve block leaks, sensor failures, and air spring leaks are common wear items. Fault codes related to EAS can be complex to diagnose without the correct tools and knowledge.
Driveshafts And Cv Joints:
Wear and tear on universal joints and CV joints can lead to clunking noises and vibration, especially under acceleration or turning.
Body Rust:
Rust can affect the chassis, sills, wheel arches, and rear crossmember, particularly in damp climates. The manual will provide guidance on inspection and repair.
Land Rover Legacy:
Known for robust, go-anywhere 4x4 vehicles, with a strong heritage in off-road capability and exploration (e.g., Land Rover Series I, II, III, and Defender).
Discovery Series 1 To 2 Transition:
The Discovery 2 replaced the original Discovery Series I. It featured updated styling, a revised interior, and significant mechanical upgrades including the TD5 diesel engine and the introduction of the Electronic Air Suspension (EAS) and Self-Levelling Suspension (SLS) options. It was built on a ladder chassis, sharing its platform with the Defender to some extent.
Production Years For Discovery 2:
1998-2004 (though the manual covers up to 2007, reflecting market variations and potential for later registrations of earlier models, or simply an extended coverage for sale).
