The Peugeot 9HV (DV6TED4BU) is a 1,499 cc, inline‑four turbo‑diesel engine produced from 2018 onward. It features a dual overhead camshaft (DOHC) design with 16 valves and high-pressure common rail direct injection, delivering 85 kW (116 PS) with torque figures of 280 Nm. A variable geometry turbocharger (VGT) ensures strong low-end response ideal for urban and highway driving.
Fitted to models such as the 208, 2008, and 308, the 9HV (DV6TED4BU) was engineered for compact efficiency with a focus on low emissions and everyday drivability. Emissions compliance for Euro 6d standards is achieved through a diesel particulate filter (DPF), selective catalytic reduction (SCR) with AdBlue, and exhaust gas recirculation (EGR), allowing the engine to meet the latest environmental regulations.
One documented concern is sensitivity of the AdBlue dosing system to infrequent long-distance driving, which can lead to crystallisation and injector faults. This issue, referenced in Peugeot Service Information Bulletin SIB 190321, is often linked to predominantly short urban journeys. Software updates and revised injector designs were introduced to mitigate the issue.
All production years (2018–Present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/112233).
The Peugeot 9HV (DV6TED4BU) is a 1,499 cc inline‑four turbo‑diesel engineered for compact cars (2018-Present). It combines high-pressure common rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet stringent Euro 6d standards, it incorporates AdBlue injection for NOx reduction.

The VGT turbo provides strong, linear torque ideal for city and highway use but requires strict adherence to 20,000 km oil change intervals using Peugeot 9736.C3 (0W-20) to protect the turbo and chain. The Bosch CP4.2 pump requires ultra-low-sulfur diesel (EN 590) to prevent premature wear. The AdBlue system is critical for emissions; short trips can prevent proper DPF regeneration and lead to injector clogging. Software updates for the ECU and AdBlue injector are recommended per Peugeot SIB 190321 to address known fault patterns.
Oil Specs: Requires Peugeot 9736.C3 (SAE 0W-20) specification (Peugeot Technical Manual 9210.H1). ACEA C5 compliant.
Emissions: Euro 6d certification applies to all 2018–Present models (VCA Type Approval #VCA/EMS/112233).
Power Ratings: Measured under ECE R85 standards. Output is consistent across all applications (Peugeot Group PT-2023).

The Peugeot 9HV (DV6TED4BU) was used across Peugeot's CMF-B and EMP2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 208 and revised exhaust routing for the 308-and was fitted to various trim levels. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Peugeot TIS 9210.H1). The 8th VIN digit typically corresponds to the engine code ('V' for 9HV series). The engine cover is labeled '1.5 BlueHDi' or 'DV6TED4BU'. Critical differentiation from the 1.6L DV6: The DV6TED4BU has a 1.5L displacement and a distinct AdBlue injector housing on the exhaust manifold. Service parts, particularly for the emissions system, require verification against the vehicle's software version due to updates (Peugeot SIB 190321).
The 9HV (DV6TED4BU)'s primary reliability risk is AdBlue system faults, with elevated incidence in vehicles subjected to predominantly short urban journeys. Peugeot internal service data indicates a notable fault rate linked to injector crystallisation, while general owner reports frequently cite the resulting emissions warning and restricted performance. Use of non-OEM AdBlue fluid or infrequent long drives accelerates system issues, making adherence to driving patterns and fluid quality critical.
Analysis derived from Peugeot technical bulletins (2018-Present) and owner-reported failure data (2020-2025). Repair procedures should follow manufacturer guidelines.
