The Peugeot 8HX (DV4TD) is a 1,398 cc, inline‑four turbo‑diesel engine produced between 2004 and 2010. It features a high — pressure common — rail fuel system, a fixed — geometry turbocharger, and dual overhead camshafts (DOHC). In standard European specification, it produced 66 kW (90 PS) and 200 Nm of torque, engineered for compact car efficiency and urban drivability.
Fitted primarily to the Peugeot 207, 206+, and Citroën C3 and C2 platforms, the DV4TD was designed for r…
Production years 2004–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6543).
The Peugeot 8HX (DV4TD) is a 1,398 cc inline‑four turbo‑diesel engineered for supermini and city cars (2004-2010). It combines common‑rail direct injection with a single fixed‑geometry turbocharger to deliver strong low-end torque and efficient urban performance. Designed to meet Euro 4 standards, it prioritises fuel economy and low emissions.

The Peugeot 8HX (DV4TD) was used across PSA Group's PF1 platform with transverse mounting. This engine received platform-specific adaptations-lighter engine mounts in the C2 and specific ECU mapping for the 207-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
The DV4TD's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in high-mileage vehicles. PSA internal reports from 2008 indicated a significant number of failures before 120,000 km, particularly in vehicles with irregular servicing. Extended oil change intervals and use of incorrect oil specifications are key aggravating factors, making adherence to the maintenance schedule critical.
Analysis derived from PSA technical bulletins (2006-2010) and UK DVSA failure statistics (2012-2023). 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 DV4TD is a frugal and torquey engine for its size, but its long-term reliability hinges on addressing the known fuel pump issue and adhering to the timing belt schedule. Vehicles that have had the pump replaced per PSA bulletin 5512 E, receive strict oil changes, and have the timing belt replaced on time can be very reliable beyond 150,000 km.
The most critical issues are high-pressure fuel pump failure and timing belt neglect. Other common problems include EGR valve clogging and glow plug/module failure. These are well-documented in PSA service bulletins and owner reports, with the fuel pump being the most frequent cause of breakdowns.
This 1.4L HDi engine was primarily used in the Peugeot 207 (2006-2010) and 206+ (2008-2010). It was also fitted to the equivalent Citroën C2 and C3 models (2004-2009), always in the 90 PS variant, providing a balance of performance and economy for these superminis.
Yes, the DV4TD can be remapped. Stage 1 tunes can safely increase power to around 105-110 PS and torque to 230+ Nm. The engine's internals are generally robust for mild tuning, but it increases stress on the fuel pump and turbo. Addressing the fuel pump weakness is highly recommended before any performance upgrades.
Fuel economy is outstanding for its era. In a Peugeot 207, expect around 4.5 L/100km (63 mpg UK) in combined driving. Highway cruising can yield figures closer to 3.8 L/100km (74 mpg UK). Real-world economy is excellent, making it one of the most economical engines of its time.
Yes. The DV4TD is an interference design. If the timing belt were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal damage. This makes adhering to the 160,000 km or 10-year replacement interval absolutely critical.
Peugeot mandates the use of oil meeting the PSA B71 2296 specification, typically a 5W-30 synthetic. Using the correct oil is critical for protecting the turbocharger and fuel pump. Change intervals should not exceed 20,000 km or 12 months.
