Discovery P360 — 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 P360? Check These First
Buy If
- Full JLR service history with documented coolant system inspections
- No signs of coolant loss or overheating (check coolant reservoir level)
- Water pump replaced as preventative at 50k+ miles
- A 2021-onward Discovery 5 facelift — the most refined petrol Discovery to date
Avoid If
- Unexplained coolant loss with no visible leak — could indicate early water pump or head gasket issues
- Overheating history or low coolant level — risk of engine damage
- Hard starting or rough idle — may indicate HPFP or injector problems
- Poor service history on a modern, high-technology engine — assume it's overdue
Closing Verdict
The P360 is the 3.0-litre six-cylinder petrol option in the facelift Discovery 5 — a refined, powerful alternative to the diesel Ingenium. It's generally more reliable than the diesel, with no timing chain catastrophe, but the cooling system requires vigilance. Water pump and coolant leaks are the main issues; catch them early and the AJ20P6 is a strong, smooth engine for the modern Discovery.
Don't Guess. Compare.

Buying Checklist
Before you buy a used Land Rover Discovery P360 (or before you commit to an engine replacement), check these:
Cold Start — Listen for smooth idle; any hesitation or rough running points to injector or fuel pump issues
Service History — Including coolant system inspections and fuel filter changes — see the map above
Coolant Level — Check reservoir when cold; any low or loss is a red flag
Water Pump — Listen for whining noise; check for coolant residue near the pump area
Turbo Boost — Test acceleration; any lack of power or hesitation?
Oil Condition — Check for fuel smell (HPFP wear) or coolant contamination
Engine Warning Light — Have codes read; unresolved issues may indicate HPFP or sensor problems
MOT History — Check for emissions-related failures (petrol is generally clean)
Buy smart. Drive with confidence.
A few checks today can save thousands tomorrow. Use this checklist to avoid the most common 320d pitfalls.
