The Peugeot DT17TED4 is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features an aluminium block and head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). This engine delivered 82 kW (112 PS) and 270 Nm of torque, engineered for efficiency and strong low — end pull in Peugeot's compact and mid — size vehicles.

The Peugeot DT17TED4 is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size SUVs and hatchbacks (2010-2018). It combines DOHC 16-valve architecture with a variable geometry turbocharger to deliver strong low-rpm torque and efficient cruising. Designed to meet Euro 5 emissions standards, it prioritises fuel economy and everyday drivability.

The Peugeot DT17TED4 was used across Peugeot's PF2 and PF3 platforms with transverse mounting. This engine received platform-specific adaptations-notably different engine mounts and exhaust configurations for the 308 versus the 3008-creating minor parts variations. 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 DT17TED4's primary reliability risk is high-pressure fuel pump failure if the drive shaft is not upgraded, with elevated incidence in high-mileage vehicles. Peugeot service documentation indicates a significant number of pre-2012 units required pump replacement before 150,000 km, while owner data suggests DPF-related issues are common in urban-driven examples. Adherence to long-distance driving cycles and using correct fuel make preventative maintenance critical.
Analysis derived from Peugeot technical bulletins (2010-2018) and Peugeot Owner's Club failure statistics (2015-2023). 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 DT17TED4 can be reliable long-term if its known issues are addressed. The most critical is replacing the high-pressure fuel pump with the revised unit if it's an early (pre-2012) engine. Regular oil changes, using the correct 5W-30 oil, and ensuring the DPF regenerates properly through highway driving are essential for longevity.
The most common and critical problem is high-pressure fuel pump failure on pre-2012 engines. Other frequent issues include EGR valve clogging, DPF regeneration problems (especially in city cars), and turbocharger actuator failures. These are well-documented in Peugeot service bulletins.
The DT17TED4 1.6L diesel was used in several Peugeot models, primarily the 308 II (2013-2018), 3008 I (2010-2016), and 5008 I (2010-2016). It was also used in Citroën models like the C4 Picasso II, as part of the PSA Group's shared engine strategy.
Aftermarket ECU tuning is common on the DT17TED4 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.
Fuel economy is excellent for its class. In a Peugeot 308, expect around 4.5-5.0 L/100km (63-56 mpg UK) on a combined cycle. Real-world figures for the heavier 3008 SUV are slightly higher, around 5.0-5.5 L/100km (56-51 mpg UK), depending on driving style and conditions.
Yes. The DT17TED4 is an interference engine. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is generally robust and designed to last the engine's lifetime with proper oil maintenance.
Peugeot specifies a fully synthetic 5W-30 oil meeting the PSA B71 2290 standard. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is crucial for protecting the DPF and other emissions components. Using the correct oil and adhering to service intervals (typically 20,000 km) is vital for engine health.
