Fuel rail pressure too low on Land Rover 2.7/3.0 TDV6 — Discovery 3/4 and Range Rover Sport HP pump shaft wear.
Land Rover P0087 — Fuel rail pressure too low on Land Rover 2.7/3.0 TDV6 — Discovery 3/4 and Range Rover Sport HP pump shaft wear. Typical UK independent garage cost: £700–£6500.
What actually causes P0087 on a Land Rover
Land Rover TDV6 P0087 is one of the most expensive diagnostics in the UK indie trade — the Bosch HP pump sheds metal that goes through rails and injectors. Catch it on the first P0087 logged and you save the customer thousands.
Land Rover engines that log P0087
- 2.7 TDV6 (Discovery 3, Range Rover Sport)
- 3.0 TDV6 (Discovery 4, Range Rover Sport)
How we diagnose P0087 on a Land Rover
- Live rail pressure data under load
- Inspect cut-open fuel filter for swarf
- Pressure-test low-pressure supply
- Quote correctly: pump + rails + injectors + lines if contaminated
- Re-code injector IMA values after fit
The common misdiagnosis to avoid
Aftermarket / remanufactured HP pumps on TDV6 have failed within months in our bay — only genuine Bosch new units give the durability expected.
Land Rover P0087 repair cost in the UK
Expect £700–£6500 including parts and labour at an independent garage. Main-dealer quotes on Land Rover are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
Bob's workshop tip
Discovery 4 TDV6 P0087 — if the customer's keeping the car long-term, do the full system once. If they're selling, advise an honest disclosure.
Codes usually seen alongside P0087 on Land Rover
- P0088
- P0089
- P1248
Symptoms drivers report with P0087
- Sudden loss of power on the motorway — car drops into limp mode at exactly 2,500 RPM
- Restarts fine after a key-cycle, then relimps under load 20 minutes later
- Hard cold-starting: cranks for 4–6 seconds before catching
- Uneven idle with a diesel-knock 'nail' from cold
- MPG drops 3–7 mpg before the light even comes on
- Metal glitter in the fuel filter housing = CP4 pump has already grenaded
Repairs that clear P0087
- Change the fuel filter and retest
- Measure injector back-leakage into a graduated tube
- Test rail pressure against commanded on live data
- Replace the pressure regulator or metering valve

Reading P0087 on a Land Rover properly
A generic reader will show P0087 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Land Rover has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.
Clearing P0087 without fixing it
Erasing the code resets the Land Rover's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.
