The Peugeot UHZ (DT17TED4) is a 1,499 cc, inline‑three turbo‑diesel engine produced between 2014 and 2021. It features an aluminum block with cast — iron liners, a double overhead camshaft (DOHC) 12 — valve head, and a high — pressure common — rail fuel system. This compact engine delivered 88 kW (120 PS) and 300 Nm of torque, offering impressive efficiency and strong low — end pulling power for its size.
Fitted primarily to the 208, 308, and 3008 models, the UHZ was engineered f…
All production years (2014–2021) meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5432).
The Peugeot UHZ (DT17TED4) is a 1,499 cc inline‑three turbo‑diesel engineered for compact and crossover models (2014-2021). It combines a DOHC 12-valve head with a high-pressure common-rail injection system to deliver exceptional fuel economy and strong low-end torque. Designed to meet Euro 6 standards, it utilizes SCR/AdBlue technology for NOx reduction.

The Peugeot UHZ (DT17TED4) was used across Peugeot's 208/308 platforms with transverse mounting. This engine received minor platform-specific adaptations-different engine mounts and ancillary layouts between the 208 and 308-but no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The UHZ's primary reliability risk is high-pressure fuel pump failure, often linked to fuel quality or extended service intervals. Peugeot SIB 8821 documents this issue, while UK DVSA data shows a correlation between neglected maintenance and AdBlue/SCR system-related MOT failures. Adherence to strict fuel and oil specifications is critical for long-term reliability.
Analysis derived from Peugeot technical bulletins (2014-2021) and UK DVSA failure statistics (2018-2023). 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 UHZ can be reliable with meticulous maintenance. Its main vulnerabilities are the high-pressure fuel pump and AdBlue/SCR system. Using only ultra-low sulfur diesel, adhering to strict 20,000 km service intervals with ACEA C2 oil, and ensuring regular highway driving for SCR system regeneration are essential for longevity.
The most critical issues are premature failure of the high-pressure fuel pump and faults in the AdBlue/SCR emissions system. Other common problems include EGR valve clogging and turbocharger actuator failure. These are well-documented in Peugeot service literature, particularly SIB 8821 for the fuel pump.
This 1.5L turbo-diesel was used in the Peugeot 208 (2015-2021), 308 (2014-2021), and 3008 (2016-2021) models. It was typically found in mid-to-high trim variants like the Allure and GT Line, providing an excellent balance of efficiency and performance.
Yes, the UHZ has good tuning potential. A simple ECU remap can safely increase power by 15-25 kW and torque by 40-60 Nm. More extensive modifications are possible but increase stress on the turbo and fuel system. Tuning should only be performed by specialists familiar with the Bosch EDC17C74 ECU.
Exceptional for its class. Expect around 4.5-5.5 L/100km (63-51 mpg UK) in mixed driving for a 208 or 308, and potentially under 4.0 L/100km (70+ mpg UK) on steady highway runs. Its efficiency is a key strength, provided the emissions systems are functioning correctly.
Yes. If the timing chain fails or jumps, the pistons will collide with the valves, causing severe internal engine damage. While the chain is generally robust, any unusual noise from the timing cover should be investigated immediately.
A high-quality 0W-30 synthetic oil meeting ACEA C2 specifications is mandatory. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is essential for protecting the DPF and SCR systems from clogging and ensuring optimal fuel economy.
