The Vauxhall D 16 DTN is a 1,496 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a single twin‑scroll turbocharger, common‑rail direct injection, and dual overhead camshafts (DOHC) with variable valve timing on the exhaust cam. In standard form it delivers 90 kW (122 PS) and 300 Nm of torque, offering strong low‑end pull for compact hatchbacks and crossovers.

Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d .
The Vauxhall D 16 DTN is a 1,496 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2018–2023). It combines common-rail direct injection with a twin-scroll turbocharger to deliver strong low-rpm torque and refined cruising. Designed to meet Euro 6d TEMP and Euro 6d standards, it balances performance with stringent emissions control.

The Vauxhall D 16 DTN was used across Vauxhall's Corsa F, Crossland, and Mokka platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Mokka for NVH control and compact exhaust manifolds in the Corsa F—and from 2020 the updated Crossland MY21 models adopted revised engine control calibration for SCR management, creating minor ECU 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 D 16 DTN is generally robust when maintained properly, but early models (2018–2019) had HPFP reliability concerns. Post-2020 revisions improved fuel system durability. Using DEXOS2 5W-30 oil, EN 590 diesel, and adhering to service intervals greatly enhances longevity.
Top issues include high-pressure fuel pump wear, DPF saturation from short trips, AdBlue/SCR system faults, and turbo actuator issues. These are documented in Vauxhall service bulletins like PI1122 and supported by DVSA MOT data.
The D 16 DTN powers the Corsa F (2019–2023), Crossland (2018–2023), and Mokka (2020–2023) in 122 PS form. All are transverse-mounted Euro 6d-compliant diesel engines with AdBlue and DPF systems.
Aftermarket ECU tuning is common on the D-16-DTN 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.
In a Corsa 1.5 Turbo D 122 PS, expect ~4.2 L/100km (city), ~3.4 L/100km (highway), or ~58 mpg UK combined. Real-world mixed driving typically returns 52–60 mpg UK. DPF/SCR regeneration cycles can temporarily increase consumption during short trips.
Yes. Like all modern DOHC engines, the D 16 DTN is an interference design. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service under proper maintenance.
Vauxhall specifies DEXOS2 5W-30 (ACEA C3) synthetic oil. This low-SAPS formulation protects the DPF and turbo. Never use DEXOS1 or non-approved oils, as they can accelerate DPF clogging and HPFP wear. Change every 20,000 km or 12 months.
