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.
Fitted to models such as the Corsa F, Crossland, and Mokka, the D 16 DTN was engineered for responsive urban driving and efficient motorway cruising. Emissions compliance was achieved through a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, allowing adherence to Euro 6d TEMP (and later Euro 6d) standards depending on model year.
One documented concern is premature failure of the high-pressure fuel pump (HPFP) under sustained high-load conditions, noted in Vauxhall Service Bulletin PI1122. This is attributed to thermal stress and marginal lubricity in certain fuel batches. From mid-2020, revised HPFP internals and updated engine control software were introduced to mitigate premature wear.
Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d (VCA UK Type Approval #VCA/EMS/7891).
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 twin-scroll turbo provides immediate throttle response but demands consistent use of EN 590 diesel and DEXOS2 oil to protect the high-pressure fuel pump and turbo bearings. Extended oil change intervals beyond 20,000 km or 12 months may accelerate HPFP wear, especially in stop-start urban use. The diesel particulate filter (DPF) and SCR system require periodic highway driving (>60 km/h for 15+ minutes) to enable passive regeneration and AdBlue dosing. Cold starts below -10°C may trigger temporary power reduction until catalyst light-off. Vauxhall SIB PI1122 recommends HPFP replacement with updated part number (13601482) for pre-2020 engines exhibiting fuel rail pressure faults.
Oil Specs: Requires DEXOS2 5W-30 (ACEA C3) specification (Vauxhall Owner's Manual Corsa F 2020). Not interchangeable with DEXOS1.
Emissions: Euro 6d TEMP applies to 2018–2019 models (VCA Type Approval #VCA/EMS/7891). Euro 6d certification confirmed for 2020–2023 builds.
Power Ratings: Measured under EU Regulation (EC) No 715/2007. Output assumes EN 590 diesel and ambient conditions per ISO 1585.

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.
Locate the engine code stamped on the front cam cover near the timing chain cover (Vauxhall TIS TIS-D16DTN-01). The 7th and 8th VIN digits identify engine variant ('D6' for D 16 DTN 122 PS). Pre-2020 units use Bosch EDC17CP55 ECU with silver casing; post-2020 models feature EDC17CP65 with black casing and updated SCR logic. Critical differentiation from 1.2 Turbo petrol: D 16 DTN has AdBlue tank, DPF, and twin-scroll turbo housing. Service parts for fuel system require production date verification—HPFPs before 06/2020 use part number 13592105; later units use 13601482 (Vauxhall SIB PI1122).
The D 16 DTN's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in sustained high-load or hot-climate use. Vauxhall internal data from 2021 indicated a measurable uptick in HPFP replacements before 80,000 km for 2018–2019 units, while UK DVSA records show DPF/SCR-related warning lights as the second-most common emissions fault in urban-driven examples. Extended oil intervals and low-quality fuel amplify HPFP and turbo stress, making adherence to DEXOS2 oil and EN 590 diesel critical.
