The Peugeot 8HR (DV4C) is a 1,398 cc, inline‑four turbo‑diesel engine produced between 2004 and 2010. It features a SOHC 8‑valve design with a fixed — geometry turbocharger and common rail direct injection. Output ranges from 50 kW (68 PS) to 66 kW (90 PS), delivering peak torque of 160–200 Nm for economical urban driving.
Fitted primarily to the Peugeot 207 and Partner van, the 8HR was engineered for compact car efficiency with low running costs and simple mechanics. Emissi…
Production years 2004–2010 meet Euro 4 standards .
The Peugeot 8HR (DV4C) is a 1,398 cc inline‑four turbo‑diesel engineered for B-segment hatchbacks and light commercial vehicles (2004-2010). It combines common‑rail direct injection with a single fixed-geometry turbocharger to deliver frugal, low-stress performance and minimal maintenance. Designed to meet Euro 4 standards, it prioritizes economy and reliability over outright power.

The Peugeot 8HR (DV4C) was used across Peugeot's PF1 and B9 platforms with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production run, ensuring full parts interchangeability. All specifications are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The 8HR (DV4C)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. PSA internal reports indicated a notable failure rate before 120,000 km in early production batches, while owner feedback frequently cites sudden engine cut-outs. Extended periods of low-load driving and infrequent oil changes accelerate pump wear, making fuel quality and maintenance adherence critical.
Analysis derived from PSA technical bulletins (2005-2010) and owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 8HR is renowned for its simplicity and durability when properly maintained. Its main weakness is the high-pressure fuel pump, which can fail if poor-quality fuel is used. With strict adherence to oil changes (PSA B71 2290) and timing belt replacement (every 100,000 km), it can easily exceed 250,000 km. It's a non-interference engine, so timing belt failure won't destroy the engine.
The most frequent issues are high-pressure fuel pump failure, EGR valve clogging, glow plug failure, and occasional turbo actuator faults. These are well-documented in PSA service bulletins. Fuel pump failure is the most critical, often leading to sudden breakdowns. EGR and glow plug issues are common maintenance items.
The 8HR (DV4C) 1.4 HDi engine was fitted to the Peugeot 207 (hatchback, SW) and the Partner van from 2004 to 2010. It was typically badged as the 1.4 HDi 70 or 1.4 HDi 90, depending on the power output. It was one of PSA's most popular small diesel engines.
Yes, but gains are modest due to the engine's SOHC 8-valve design and fixed-geometry turbo. ECU remapping can typically increase power to around 100-105 PS and torque to 220-230 Nm. Supporting modifications are generally not required, but ensure the clutch and turbo actuator are in good condition. It's not a high-performance engine, so expectations should be realistic.
Real-world fuel economy is exceptional for its era. In a Peugeot 207, expect around 4.5-5.0 L/100km (63-56 mpg UK) in mixed driving. Highway cruising can yield 3.8-4.2 L/100km (74-67 mpg UK). It's one of the most economical engines PSA ever produced, making it ideal for high-mileage drivers.
No. The 8HR (DV4C) is a non-interference engine. If the timing belt were to fail, the pistons and valves will not collide, preventing catastrophic internal damage. The engine will simply stop running. This is a major reliability advantage, but the belt should still be replaced at the recommended interval to avoid being stranded.
Peugeot mandates the use of oil meeting the PSA B71 2290 specification, typically a 5W-30 synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for protecting the DPF (if equipped) and catalytic converter from clogging and ensuring proper lubrication of the fuel system components.
