Peugeot P0087

Fuel rail pressure too low on Peugeot — 1.6/2.0 HDi lift pump and Bosch DRV failure.

Peugeot P0087 — Fuel rail pressure too low on Peugeot — 1.6/2.0 HDi lift pump and Bosch DRV failure. Typical UK independent garage cost: £180–£1400.

What actually causes P0087 on a Peugeot

PSA HDi P0087 is normally the in-tank lift pump or DRV — both are bolt-on. Avoid jumping straight to HP pump.

Peugeot engines that log P0087

• 1.6 HDi DV6 (208/308/Partner)
• 2.0 HDi DW10 (308/508/5008)

How we diagnose P0087 on a Peugeot

1. In-tank lift pump test
2. Filter swarf
3. DRV resistance
4. Full pump only if supply healthy and rail still low

The common misdiagnosis to avoid

PSA dealer prices for HP pumps are insulting — Bosch reman from a diesel specialist is half the cost.

Peugeot P0087 repair cost in the UK

Expect £180–£1400 including parts and labour at an independent garage. Main-dealer quotes on Peugeot 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

DV6 P0087 — lift pump fitted with a fresh filter is the standard combo job.

Codes usually seen alongside P0087 on Peugeot

• P0088
• P0089

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 Peugeot 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 Peugeot 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 Peugeot'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.
