The Citroën 8HT (DV4TD) is a 1,398 cc, inline — four turbocharged diesel engine produced between 2004 and 2012. It belongs to the PSA DV engine family, co — developed with Ford for transverse applications in compact vehicles. Featuring a cast — iron block, aluminium head, and common — rail direct injection, it delivers responsive torque and strong fuel economy. In standard tune, it produces 50 kW (68 PS) and 160 Nm of torque.
Fitted to models such as the Citroën C3, C2, and Berli…
Production years 2004–2012 meet Euro 4 emissions standards (VCA UK Type Approval #VCA/EMS/9123).
The Citroën 8HT (DV4TD) is a 1,398 cc inline-four turbocharged diesel engine designed for compact urban vehicles (2004–2012). It combines common-rail injection with a fixed-geometry turbocharger to deliver strong low-end torque and efficient operation. Designed to meet Euro 4 standards, it balances economy with acceptable performance for city driving.

The Citroën 8HT (DV4TD) was used across Citroën's B-segment platforms with transverse mounting and shared with Peugeot under the DV engine program. This engine received platform-specific calibrations-adapted EGR flow in the C3 and revised DPF regeneration logic in the Partner-and from 2008 the facelifted C2 adopted updated injector nozzles and ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The DV4TD's primary reliability risk is fuel injector coking on high-mileage or poorly maintained units, with elevated incidence in urban-driven examples. PSA internal quality reports from 2010 indicated a significant number of pre-2008 units requiring injector cleaning before 120,000 km, while UK DVSA MOT records show increased emissions-related failures in stop-start use. Extended service intervals and low-quality fuel accelerate degradation, making service adherence and fuel quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV4TD is generally reliable when maintained properly. Its compact design and proven architecture make it durable, but critical attention must be paid to the 120,000 km timing belt interval and fuel quality. Injector coking is common on pre-2008 units. With timely servicing and use of correct oil (5W-30), these engines regularly exceed 180,000 km.
The most documented issues are fuel injector coking due to poor diesel quality, timing belt failure from missed services, and DPF clogging from short trips. These are addressed in PSA service bulletins, particularly SIB-ENG-2008-06. EGR fouling is also seen in high-mileage urban examples. Post-2008 models feature improved injectors and reliability.
The DV4TD was used in the Citroën C3 (1.4 HDi 70), C2 (1.4 HDi 70), and Berlingo (1.4 HDi 70) from 2004 to 2012. It was also shared with Peugeot (206 1.4 HDi 70, 207 1.4 HDi 70) under the DV engine family. All applications are front-wheel drive with transverse engine mounting.
The DV4TD has limited tuning potential due to its small displacement and fixed-geometry turbo. Mild ECU remaps can yield +10–15 kW, but gains are modest. Aftermarket exhausts or air intakes offer slight improvements but are not cost-effective for most users. Most owners focus on reliability rather than performance upgrades.
In combined driving, expect 4.8–5.4 L/100 km (52–59 mpg UK). Real-world consumption is excellent in city driving (~4.6 L/100km), but motorway efficiency drops to ~6.0 L/100km (47 mpg UK). Fuel quality and driving style significantly impact economy, especially DPF regeneration cycles.
Yes. The DV4TD is an interference engine. If the timing belt fails or jumps, piston-to-valve contact will occur, causing catastrophic internal damage. Given the 120,000 km service interval, proactive replacement of the belt, tensioner, and water pump is essential to avoid expensive repairs.
PSA specifies Total Rubia TIR 5W-30 (or equivalent meeting PSA B71 2300). This low-SAPS oil is essential for DPF system longevity. Oil must be changed every 15,000 km or annually to maintain lubrication and prevent soot buildup, especially in mixed driving conditions.
