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

1. Live rail pressure data under load
2. Inspect cut-open fuel filter for swarf
3. Pressure-test low-pressure supply
4. Quote correctly: pump + rails + injectors + lines if contaminated
5. 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.

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.
