The Peugeot DT20C is a 1,998 cc, inline‑four turbo‑diesel engine introduced in 2021 as part of Stellantis’ next‑generation diesel family. It features a double overhead camshaft (DOHC), 16‑valve architecture with a variable geometry turbocharger (VGT) and high‑pressure common‑rail direct injection operating up to 2,500 bar. Peak output is 110 kW (150 PS) with 370 Nm of torque, engineered for refined urban and motorway performance while meeting stringent emissions t…
All production years (2021–present) meet Euro 6d standards .
The Peugeot DT20C is a 1,998 cc inline‑four turbo‑diesel engineered for midsize SUVs (2021–present). It combines DOHC valvetrain architecture with a variable-geometry turbocharger and ultra-high-pressure common-rail injection to deliver responsive torque and low-end refinement. Designed to meet Euro 6d emissions standards, it integrates AdBlue-based SCR for stringent NOx control.

The Peugeot DT20C was used across Stellantis's EMP2 platform with transverse mounting and shared with Citroën and DS. This engine received platform-specific adaptations—revised engine mounts in the 5008 III and modified AdBlue tank routing in the 3008 III—and from Q3 2022 the updated camshaft and pump couplings created minor 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 DT20C is generally robust if maintained correctly. Early units (2021–mid-2022) are susceptible to cam lobe wear under high-load or urban use, but Q3 2022+ revisions improved durability. Using correct low-SAPS oil (ACEA C2/C3), adhering to service intervals, and maintaining AdBlue quality greatly enhance longevity.
Top issues include camshaft lobe wear driving the fuel pump, AdBlue/SCR system faults, EGR valve carbon buildup, and timing chain tensioner wear. These are documented in Stellantis service bulletins SI‑22‑03 and TIS updates from 2022–2023.
Primarily the Peugeot 3008 III and 5008 III (2021–present) in 2.0 BlueHDi 150 variants. It was also introduced in the facelifted Citroën C5 Aircross and DS 7 Crossback from 2022 onward under the same BlueHDi branding.
Aftermarket ECU tuning is common on the DT20C 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.
Efficient for its class: ~5.6 L/100km (city) and ~4.3 L/100km (highway), or 50–66 mpg UK combined. Real-world figures depend heavily on driving style, AdBlue consumption, and DPF regeneration cycles—consistent mixed use optimizes economy.
Yes. The DT20C is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing severe internal damage. Prompt attention to chain rattle or timing faults is essential.
Stellantis specifies 0W‑30 synthetic oil meeting ACEA C2/C3 and PSA B71 2312 standards. This low-SAPS formulation protects the DPF and SCR systems and ensures proper lubrication of the cam-driven fuel pump. Change every 20,000 km or annually.
