P0087 on Dacia by model: symptoms, diagnosis and fix
The K9K 1.5 dCi diesel — used across Dacia Sandero, Duster, Logan, plus Renault Clio/Captur/Kadjar, Nissan Note/Juke — suffers Bosch CP1 high-pressure pump and injector failure typically at 100,000-180,000 km. Worst case: pump self-destructs and sends metal particles through the entire fuel system, requiring full rail+pump+injector replacement (€2,500-€4,000).
Common Symptoms
- rough start
- misfire
- limp mode
- fuel smell
- no start
How to Fix
Back-leak test at 80,000 km as a precaution. Single-injector replacement €250-€500. If pump has failed catastrophically, full system flush + replacement is the only safe option. Use only diesel from major-brand stations and add a fuel-system cleaner per service.

Frequently asked questions
What does P0087 mean on a Dacia?
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On Dacia it is documented across 1 model: Sandero.

The most common causes of P0087 are: Clogged or dirty fuel filter, Weak or failing fuel pump (lift pump or high-pressure pump), Faulty fuel pressure regulator or control valve, Restricted or leaking fuel lines, Faulty fuel pressure sensor, Air in the fuel system or running low on fuel, Worn high-pressure pump (direct injection/diesel). The specific cause varies by vehicle.
