Discovery TD5 — Repair, Buy, or Replace?
Every 320d has a story. Make the right call with clear data, real-world costs, and honest guidance from UK specialists.
Can It Be Repaired?
Buying This TD5? Check These First
Buy If
- Oil pump bolt replaced (critical — confirm on any early 10P engine)
- Injector wiring harness checked and free of oil contamination
- No signs of overheating or coolant loss (head gasket/cylinder head health)
- Full service history with regular oil changes (TD5s are sensitive to oil quality)
Avoid If
- No record of oil pump bolt work on a 10P engine — assume it's overdue
- Oil in the red ECU plug — injector harness contamination is likely
- Overheating history or pressurised coolant system — head may be cracked
- Excessive black smoke or hard starting — injection pump or injector issues
Closing Verdict
The TD5 is one of Land Rover's most respected engines — a 2.5-litre five-cylinder turbo-diesel with a cast-iron block and no timing belt to worry about. Its reputation is built on torque and durability, not refinement. The oil pump bolt on early engines is its one critical vulnerability — address that and the TD5 will outlast the chassis around it. With only 76 TD5 Discoveries still on UK roads, well-maintained examples are becoming increasingly collectable.

Buying Checklist
Before you buy a used Land Rover Discovery TD5 (or before you commit to an engine replacement), check these:
Oil Pump Bolt — Confirm replacement on any 10P engine (critical — ask for proof)
Cold Start — Listen for smooth start; any hesitation or rough idle points to injector or harness issues
ECU Connector — Check the red plug for oil contamination (injector harness warning)
Coolant System — Check for pressurisation, oil in coolant, or coolant loss (head gasket/head crack warning)
Smoke Check — Black smoke = over-fuelling; white smoke = coolant ingress; blue smoke = oil burning
Turbo Boost — Test acceleration; any lack of power or excessive smoke?
Service History — Including oil change intervals (TD5s are sensitive to oil quality) — see the map above
MOT History — Check for emissions-related failures and structural corrosion (Discovery 2 chassis are known to rust)
Buy smart. Drive with confidence.
A few checks today can save thousands tomorrow. Use this checklist to avoid the most common 320d pitfalls.
