The Citroën 9HW (DV6BTED4) is a 1,560 cc, inline — four, turbocharged diesel engine produced between 2008 and 2018. It is part of the PSA DV (Diester/Vert) engine family, co — developed with Ford as part of the DLD family, and designed for efficiency and low emissions. Featuring high — pressure common — rail direct injection, variable geometry turbocharging (VGT), and DOHC 16 — valve layout, it produces 88 kW (120 PS) at 3,750 rpm and 320 Nm at 1,750 rpm, delivering strong low — e…

The Citroën 9HW (DV6BTED4) is a 1,560 cc inline-four turbocharged diesel engine engineered for mid-size applications (2008–2018). It combines high-pressure common-rail injection with a variable geometry turbocharger to deliver strong low-RPM torque and efficient cruising. Designed to meet Euro 5 standards, it balances performance with acceptable fuel economy and emissions for its class.

The Citroën 9HW (DV6BTED4) was used across Citroën's PF2/PF3 platforms with transverse mounting and shared with Peugeot and Ford derivatives. This engine received platform-specific adaptations-reinforced mounts in the C5 and revised intake manifolds in the C4 Picasso-and from 2014 the facelifted C4 adopted updated ECU mapping and SCR calibration, 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV6BTED4 delivers strong torque and good efficiency, but pre-2014 models have known timing chain concerns. Later revisions (post-2014) improved chain guide durability. Well-maintained engines with regular oil changes using correct specification (5W-30) can exceed 180,000 km. Urban drivers should prioritize oil quality and avoid short trips to prevent DPF issues.
Primary issues include timing chain wear (especially pre-2014), DPF clogging, EGR valve coking, and high-pressure fuel pump failure. These are documented in PSA service bulletins and linked to oil quality, fuel standards, and driving patterns. Regular maintenance and use of EN 590 diesel are essential to mitigate risks.
The DV6BTED4 was used in the C4 (1.6 HDi 120), C4 Picasso (1.6 HDi 120), and C5 (1.6 HDi 120) from 2008 to 2018. It was also shared with Peugeot (308, 508) and Ford (C-MAX, S-MAX) under the DLD-416 designation. All models are Euro 5 compliant.
Aftermarket ECU tuning is common on the 9HW-DV6BTED4 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Official combined figures range from 4.2–4.8 L/100 km (~67–58 mpg UK). Real-world consumption is typically 5.0–6.0 L/100 km (~56–47 mpg UK), depending on driving style. The C4 Picasso and C5 see higher consumption. Using EN 590 diesel ensures optimal efficiency and prevents fuel system damage.
Yes. The DV6BTED4 is an interference engine. If the timing chain fails or skips, pistons will contact open valves, resulting in catastrophic engine damage. Any timing-related rattles must be investigated immediately. Replacement of the chain kit at recommended intervals is critical.
PSA specifies Total Rubia TIR 5W-30 (or equivalent meeting PSA B71 2290). This low-SAPS oil is essential for turbocharger and DPF system protection. Oil must be changed every 15,000 km or annually to prevent sludge, coking, and premature wear.
