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 Berlingo, as well as the Peugeot 206 and 207, the DV4TD was engineered for urban efficiency and low running costs. It prioritizes city driving practicality and fleet economy, making it ideal for first-time drivers and commercial use. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 4 standards throughout its production run.
One documented concern is fuel injector coking due to low-sulfur diesel quality, particularly in high-mileage or short-trip driven units. This issue, highlighted in PSA Service Bulletin SIB-ENG-2008-06, can lead to misfires, rough idle, and increased emissions. From 2008, revised injector nozzle designs and updated ECU mapping were introduced to improve fuel atomization and deposit resistance.
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 fixed-geometry turbo provides strong low-RPM torque ideal for stop-start driving but requires adherence to 120,000 km timing belt intervals to prevent valve/piston contact. Total Rubia TIR 5W-30 oil is essential due to its low-SAPS formulation and compatibility with DPF systems. The Bosch CRS 2-16 system demands ultra-low-sulfur diesel (EN 590) to prevent injector coking and internal wear. DPF regeneration requires regular highway runs to prevent clogging. Post-2008 models feature improved injector nozzles and ECU calibration, enhancing deposit resistance. Cold-start idling should be minimized to reduce EGR soot buildup.
Oil Specs: Requires Total Rubia TIR 5W-30 or equivalent meeting PSA B71 2300. Supersedes ACEA C3.
Emissions: Euro 4 certification applies to all models (2004–2012) (VCA Type Approval #VCA/EMS/9123).
Power Ratings: Measured under ECE R85 standards. Output requires EN 590 diesel for optimal injection performance (PSA TIS DV-ENG-06).

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.
Locate the engine code stamped vertically on the left-side engine block near the transmission bellhousing (PSA TIS DV-ENG-07). The 8th VIN digit indicates engine type ('D' for DV4TD). Pre-2008 models have silver injector bodies; post-2008 units feature black nozzles with revised spray pattern. Critical differentiation: DV4TD uses a Bosch CRS 2-16 common-rail system with Garrett GT12 turbo, while the earlier DW8 uses a mechanical injection pump. Service parts require model-year verification—injection components from pre- and post-2008 builds are not interchangeable (PSA SIB-ENG-2008-06).
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.
