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 compa…

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 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.
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.
Analysis derived from Peugeot technical bulletins (2018-Present) and owner-reported failure data (2020-2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 9HV (DV6TED4BU) is generally a robust and economical engine, but its complexity lies in the emissions system. With regular long-distance driving to ensure proper DPF and AdBlue system function, and strict adherence to oil changes using 0W-20, these engines can be very reliable. Neglecting the AdBlue system or using short trips exclusively is the primary cause of major issues.
The most frequent issues are AdBlue injector crystallisation or failure, NOx sensor faults leading to emissions warnings, EGR valve clogging causing performance issues, and high-pressure fuel pump failures. These are well-documented in Peugeot service information and are often related to usage patterns or fluid quality.
This 1.5L diesel engine is used in Peugeot's current compact and mid-size models, including the 208 (2019-Present), 2008 (2019-Present), and 308 (2018-Present), typically in Allure or GT trims. It is part of the BlueHDi engine family and is not used in larger Peugeot models like the 5008.
Yes, moderately. The 9HV (DV6TED4BU) can be remapped for modest power gains (+15-25 kW), but its small displacement and focus on emissions compliance mean it's not a high-tuning-potential engine. Significant power increases would require extensive modifications and are not recommended due to potential reliability impacts on the emissions system and internals.
Expect combined fuel economy of approximately 4.0-4.5 L/100km (71-63 mpg UK) in a Peugeot 208 Allure. Real-world figures are excellent for highway driving but can be slightly higher in city use, especially if DPF regeneration is frequent. The official WLTP figures are quite achievable with gentle driving, making it one of the most economical diesel engines.
Yes. The 9HV (DV6TED4BU) is an interference engine. If the timing chain were to fail (a very rare occurrence) or if the cam timing is severely disrupted, piston-to-valve contact is possible, resulting in significant internal engine damage. The chain is designed for the engine's lifetime under normal conditions.
Peugeot mandates a 0W-20 synthetic oil meeting their specific 9736.C3 standard (or equivalent ACEA C5). Using the correct low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for the longevity of the DPF and AdBlue system. Change intervals should not exceed 20,000 km or 1 year.
