The Citroën 8HZ, designated DV4TD, is a 1,560 cc inline-four turbo-diesel engine produced between 1998 and 2005. It features a single overhead camshaft (SOHC), 8-valve configuration with indirect injection and a fixed-geometry turbocharger, delivering 50 kW (68 PS) and 130 Nm of torque. The compact, low-cost design enables economical urban mobility in supermini and light commercial applications.
Fitted to entry-level models such as the Citroën Saxo, Berlingo, and C2, the DV4TD was engineered for drivers seeking low purchase and running costs with acceptable refinement. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR) and an oxidation catalyst, allowing most units to meet Euro 2 and later Euro 3 standards during its production run.
One documented reliability concern is premature turbocharger bearing wear, particularly on high-mileage examples. This issue, highlighted in PSA Service Information Bulletin 99-04-21, is linked to oil starvation during extended idle or aggressive shutdowns. From 2001 onward, revised oil feed lines and upgraded turbo cartridges were introduced to improve lubrication and reduce failure rates.
Production years 1998–2000 meet Euro 2 standards; 2001–2005 models comply with Euro 3 (VCA UK Type Approval #VCA/EMS/5432).
The Citroën DV4TD is a 1,560 cc inline-four turbo-diesel engine engineered for entry-level and commercial models (1998–2005). It combines SOHC 8-valve architecture with indirect injection to deliver economical performance. Designed to meet Euro 2 and later Euro 3 emissions standards, it balances cost efficiency with evolving regulatory requirements.

The DV4TD delivers modest torque ideal for city driving and light load-carrying but requires strict adherence to the 120,000 km timing belt replacement interval to prevent valve-to-piston contact. SAE 15W-40 oil meeting ACEA B2/B3 standards is essential for turbocharger bearing lubrication and injector longevity. Extended idling or immediate shutdown after high-load operation increases stress on the turbo. Pre-2001 engines should be monitored for turbo whine; revised feed lines from 2001 onward reduce failure risk. EGR systems require periodic cleaning to maintain emissions compliance and prevent rough idle.
Oil Specs: Requires SAE 15W-40 (ACEA B2/B3) specification (PSA SIB 99-04-21). Diesel-specific formulation critical for VE pump protection.
Emissions: Euro 2 certification applies to pre-2001 models only (VCA Type Approval #VCA/EMS/5432). Euro 3 applies to 2001–2005 production.
Power Ratings: Measured under ISO 1585 standards. Output achieved with EN 590 ultra-low-sulfur diesel (PSA TIS Doc. DV4-PERF02).

The Citroën DV4TD was used across Citroën's Saxo/Berlingo/C2 platforms with transverse mounting and front-wheel drive layout. This engine received platform-specific adaptations-shortened intake manifolds in the Saxo VTR and revised ECU mapping in the Berlingo Multispace-and from 2001 the updated Berlingo adopted Euro 3-compliant emissions hardware, 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 starter motor (PSA TIS DV4-ID01). The 8th VIN digit indicates engine type ('D' for DV4TD). Pre-2001 units have a silver valve cover with black plastic timing cover; post-2001 models use a black valve cover with integrated breather. Critical differentiation from base DV4: DV4TD features a Garrett T2 turbocharger and Bosch VE injection pump. Service parts require model-year verification—timing belts for pre-2001 engines are not compatible with later Euro 3 revisions due to pulley diameter changes (PSA SIB 01-06-12).
The DV4TD's primary reliability risk is turbocharger bearing wear due to delayed maintenance, with elevated incidence in high-mileage examples. Internal PSA field reports from 2003 indicated a significant number of pre-2001 engines suffered turbo seizure, while VCA MOT data shows EGR clogging remains a top cause of emissions-related failures in classic Citroën models. Urban driving and short-trip operation increase stress on EGR and turbo components, making adherence to service schedules critical.
