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…
Production years 1998–2000 meet Euro 2 standards; 2001–2005 models comply with Euro 3 .
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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV4TD offers basic performance and reasonable reliability when properly maintained. Early models (1998–2000) are prone to turbocharger failure, while all variants demand strict timing belt changes every 120,000 km. Well-maintained engines with revised components (post-2001) can achieve high longevity. Using correct oil (15W-40 ACEA B2/B3) and avoiding immediate shutdown after load helps ensure reliability.
Key issues include premature turbocharger bearing wear (especially pre-2001), EGR valve clogging, timing belt failure due to missed intervals, and injection pump wear. These are documented in PSA service bulletins and owner reports. Turbo failure from oil starvation is common if maintenance is delayed. Regular inspections and OEM-recommended servicing mitigate most risks.
The DV4TD was used in entry-level Citroën models: Saxo 1.6 D/VTR Diesel (1998–2003), Berlingo 1.6 HDi (1999–2005), and C2 1.6 HDi (2003–2005). It was not used outside the Citroën lineup. Each model has unique ECU mapping and intake tuning, so direct swaps require compatibility checks.
Limited tuning potential. ECU remapping can yield +10–15 kW on optimized setups. Supporting mods like performance intercoolers and exhaust upgrades are possible but constrained by the SOHC 8-valve design and VE injection pump. Over-tuning without fuel and cooling upgrades risks turbo and pump failure. Most owners prioritize reliability over performance.
Excellent for a 1.6L diesel of its era. In a Berlingo 1.6 HDi, consumption is ~6.8 L/100km (city) and ~4.9 L/100km (highway), or about 48 mpg UK combined. Real-world figures depend on load and driving style—expect 42–50 mpg (UK) under mixed conditions with careful driving.
Yes. The DV4TD is an interference engine. If the timing belt fails or jumps, the pistons can strike the open valves, causing catastrophic internal damage. This makes adherence to the 120,000 km belt replacement interval absolutely critical. Any signs of belt wear or tensioner noise should prompt immediate inspection.
PSA specifies SAE 15W-40 oil meeting ACEA B2/B3 standards. Mineral or semi-synthetic oils are acceptable. Change intervals should not exceed 15,000 km or 12 months. Proper oil selection ensures adequate turbo and injection pump lubrication, especially in pre-2001 engines with known turbo durability limitations.
