The Vauxhall A17DTE is a 1,499 cc, inline‑three turbo‑diesel engine produced between 2017 and 2023. Developed jointly with Stellantis (formerly PSA) as part of the DV5 family, it features a high — pressure common‑rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshaashes (DOHC). In standard form it delivers 81–88 kW (110–120 PS) with peak torque of 250–270 Nm, offering responsive urban drivability with low fuel consumption.

All production years (2017–2023) comply with Euro 6d emissions standards .
The Vauxhall A17DTE is a 1,499 cc inline‑three turbo‑diesel engineered for subcompact and compact SUVs (2017–2023). It combines high-pressure common‑rail injection with a single variable‑geometry turbocharger to deliver brisk low‑end response and class-leading CO₂ figures. Designed to meet Euro 6d emissions standards, it integrates SCR/AdBlue technology alongside EGR and DPF systems.

The Vauxhall A17DTE was used across Vauxhall's Corsa E, Crossland, and Grandland platforms with transverse mounting and shared extensively with Stellantis (Peugeot 208/2008, Citroën C3 Aircross). This engine received platform-specific calibrations—revised engine mounts in the Grandland and acoustic covers in the Corsa—and from 2020 the AdBlue system hardware was updated to reduce crystallisation risk, creating 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 A17DTE offers excellent fuel economy and low CO₂, but early models (2017–2020) are prone to AdBlue crystallisation and CP4.2 pump sensitivity. Post-2020 revisions improved AdBlue reliability. Longevity depends heavily on using DEXOS2 0W-30 oil, EN 590 diesel, and including regular highway driving to enable full emissions system regeneration.
Top issues include AdBlue line crystallisation, Bosch CP4.2 fuel pump wear, EGR valve sticking, and DPF pressure sensor drift. These are documented in Vauxhall TSBs and DVSA MOT data. Regular highway driving and correct oil/fuel greatly reduce risk.
The A17DTE powered the Corsa E (2019–2023), Crossland (2017–2023), and Grandland (2017–2023) in 1.5 Turbo D 110/130 variants. It is mechanically identical to the Stellantis DV5RC engine used in Peugeot 208/2008 and Citroën C3 Aircross from the same era.
Aftermarket ECU tuning is common on the A-17-DTE 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.
Excellent for its class. In a Corsa 1.5 Turbo D 110, expect ~4.5 L/100km (city) and ~3.3 L/100km (highway), or ~63 mpg UK combined. Real-world mixed driving typically returns 55–60 mpg (UK) with conservative use and regular highway segments.
Yes. The A17DTE is an interference design. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally robust with proper oil maintenance.
Vauxhall specifies DEXOS2 0W-30 synthetic oil. This is mandatory for turbo-diesel protection, CP4.2 pump lubrication, and low-temperature fluidity. Change every 15,000 km or annually—whichever comes first—to prevent soot buildup and wear.
