Land Rover Discovery 2 (Series II): A Comprehensive Guide
The Land Rover Discovery 2, often referred to as the Series II, represents the second generation of Land Rover's popular Discovery line. Introduced in late 1998 (as a 1999 model in some markets) and produced until 2004, the Discovery 2 aimed to build upon the success of its predecessor while addressing some of its shortcomings. This guide provides an in-depth look at the Discovery 2, covering its history, common issues, driving experience, and offering essential buying advice.
1. Introduction: Building on a Legacy
The Discovery 2 is a mid-size SUV, designed with both on-road comfort and off-road capability in mind. It belongs to the category of premium SUVs, offering a blend of practicality, ruggedness, and a touch of luxury. While visually similar to the original Discovery, Land Rover claimed over 70% of the Discovery 2's components were new or redesigned. This included significant changes to the chassis, suspension, and interior, aiming for improved refinement and reliability.
2. Generations: The Discovery 2 (1998-2004)
The Discovery 2 only saw one major generation, but experienced subtle refinements over its production run:
- 1998-2002 (Phase 1): Initial release, featuring the original design elements.
- 2003-2004 (Phase 2 Facelift): This facelift saw a revised front end with redesigned headlights, grille, and front bumper. The interior also received minor updates, and some mechanical improvements were implemented to address known reliability issues. Cruise Control was made standard on many models.
Key Changes Across the Discovery 2:
- Engine Options: Primarily offered with either a 4.0-liter Rover V8 petrol engine or a 2.5-liter Td5 inline-five diesel engine.
- Chassis & Suspension: Improvements to the chassis for better rigidity and handling. Some models featured self-leveling rear air suspension (SLS), offering enhanced ride comfort and load-carrying capacity. Electronic Traction Control (ETC) and Hill Descent Control (HDC) were also available.
- Interior: Redesigned interior with improved materials and ergonomics compared to the original Discovery.
- Electronic Architecture: Introduction of more sophisticated electronic systems, which unfortunately, contributed to some of the vehicle's reliability woes.
3. Reliability & Common Issues
The Discovery 2, while offering a compelling package, is known for its share of reliability challenges. Addressing these issues is crucial for ownership enjoyment.
Engine Issues:
- 4.0L Rover V8:
- Slipping Liners (Top Hatting): The 4.0L V8 engine is infamous for cylinder liner problems. The liners can slip and cause head gasket failure, overheating, and ultimately, engine failure. This is especially prevalent in engines that have been overheated previously. "Top Hat" liners are a preventative measure often taken during rebuilds.
- Oil Leaks: Prone to oil leaks from various locations, including the valve covers, oil pan, and rear main seal. Regular monitoring and maintenance are essential.
- Overheating: Cooling system issues, such as a failing water pump or clogged radiator, can lead to overheating.
- 2.5L Td5 Diesel:
- Injector Harness Issues: The injector harness runs inside the cylinder head and is submerged in oil. Oil can wick through the harness and contaminate the ECU, causing various electrical problems.
- Fuel Pump Failure: The in-tank fuel pump can fail, leading to fuel starvation.
- Cylinder Head Cracking: The Td5 cylinder head can be prone to cracking, particularly in hotter climates or with poorly maintained cooling systems.
Suspension & Chassis:
- Air Suspension (SLS) Failure: The self-leveling suspension system can be problematic. Air leaks, compressor failure, and sensor issues are common. Converting to coil springs is a popular and reliable alternative.
- Rust: The Discovery 2 is susceptible to rust, particularly in areas with harsh winters. Check the chassis, floor pans, and body panels carefully.
- Rotting Brake Lines: Similar to many vehicles of this era, brake lines can corrode and leak. Thorough inspection is crucial for safety.
Electrical Issues:
- "Three Amigos": The infamous "Three Amigos" – ABS, Traction Control, and Hill Descent Control lights illuminating on the dashboard – often indicate a faulty ABS modulator, wheel speed sensor, or shuttle valve switch.
- Central Locking Problems: Faulty door lock actuators and receiver units can lead to central locking malfunctions.
- BCU (Body Control Unit) Issues: The BCU controls various electrical functions and can be prone to failure, leading to a range of problems.
- ACE (Active Cornering Enhancement) Leaks: If equipped, the ACE system is prone to leaks from the pump, valve block and pipes. This system is also often removed for simplicity.
4. Driving Experience
The Discovery 2 offers a unique driving experience that blends on-road comfort with impressive off-road capabilities.
Pros:
- Off-Road Prowess: The Discovery 2 is highly capable off-road, thanks to its robust four-wheel-drive system, high ground clearance, and electronic aids like Traction Control and Hill Descent Control.
- Spacious Interior: The cabin is spacious and comfortable, offering ample room for passengers and cargo.
- Distinctive Styling: The classic Land Rover design is timeless and appealing.
- Diesel Fuel Economy: The Td5 diesel engine offers respectable fuel economy compared to the V8 petrol version.
Cons:
- Reliability Concerns: As outlined above, the Discovery 2 is prone to various mechanical and electrical issues.
- On-Road Handling: While improved compared to the original Discovery, the Discovery 2's on-road handling is not as refined as some modern SUVs. Body roll can be noticeable in corners.
- Fuel Consumption (V8): The 4.0L V8 engine can be thirsty, especially in city driving.
- Parts Availability: Some parts can be difficult to source and may be expensive.
5. Buying Advice
Buying a Discovery 2 requires careful consideration due to its age and potential for issues.
Years to Look For:
- 2003-2004 (Facelift Models): The later facelift models generally benefit from some mechanical improvements and updated styling. These are often considered the most desirable.
What to Avoid:
- Engines with a history of Overheating: Engines that show signs of prior overheating should be viewed with extreme caution due to the high likelihood of slipped cylinder liners in the 4.0L V8.
- Vehicles with Significant Rust: Extensive rust can be costly to repair and compromise the vehicle's structural integrity.
- Neglected Examples: A poorly maintained Discovery 2 is likely to be a money pit. Look for vehicles with a comprehensive service history.
Pre-Purchase Inspection Checklist:
- Engine Check: Listen for any unusual noises, check for oil leaks, and ensure the engine runs smoothly. Perform a compression test if possible.
- Cooling System: Inspect the radiator, hoses, and water pump for leaks or damage. Check for signs of overheating.
- Suspension Test: Test the self-leveling suspension (if equipped) to ensure it functions correctly. Look for air leaks.
- Electrical System: Check all electrical components, including lights, windows, central locking, and the "Three Amigos" lights.
- Rust Inspection: Thoroughly inspect the chassis, floor pans, body panels, and brake lines for rust.
- Service History: Review the service history carefully. Pay attention to any major repairs or maintenance items that have been performed.
- Test Drive: Take the vehicle for a thorough test drive, paying attention to the engine, transmission, suspension, and brakes. Test the off-road capabilities if possible.
Conclusion: The Land Rover Discovery 2 is a capable and distinctive SUV with a unique charm. However, its reliability issues require careful consideration. By being aware of the common problems and performing a thorough pre-purchase inspection, you can increase your chances of finding a Discovery 2 that provides years of enjoyable ownership.
