The Vauxhall B16DTR is a 1,496 cc, inline‑three turbo‑diesel engine produced between 2018 and 2023. It features common rail direct injection, a single variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 88 kW (120 PS) and 300 Nm of torque, providing strong low‑rpm pull for responsive urban and motorway driving.
Fitted to models such as the Corsa F, Crossland, and Grandland, including the 1.5 CDTi 120 variants, the B16DT…
Production years 2018–2019 meet Euro 6d-TEMP standards; 2020–2023 models comply with Euro 6d .
The Vauxhall B16DTR is a 1,496 cc inline‑three turbo‑diesel engineered for subcompact and compact SUV platforms (2018–2023). It combines common-rail direct injection with a single variable-geometry turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet Euro 6d-TEMP and Euro 6d standards, it balances everyday performance with economy and emissions compliance.

The Vauxhall B16DTR was used across Vauxhall's Corsa F, Crossland, and Grandland platforms with transverse mounting and shared with Peugeot and Citroën under Stellantis (formerly PSA-GM) collaboration. This engine received platform-specific adaptations—revised engine mounts in the Grandland and modified exhaust routing in the Corsa F—and from 2020 the Euro 6d update introduced a closed crankcase ventilation (CCV) system, creating interchange limits. Partnerships allowed Peugeot's 1.5 BlueHDi to share core architecture. 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 B16DTR offers good efficiency and strong low-end torque, but early models (2018–2019) had fuel pump coupling concerns. Post-2020 Euro 6d revisions improved durability. With strict adherence to GM dexos2 Gen 2 oil changes and use of EN 590 diesel, well-maintained examples can exceed 200,000 km reliably.
Top issues include high-pressure fuel pump coupling wear, EGR/DPF clogging from short trips, turbo actuator faults, and occasional injector leakage. These are documented in Vauxhall SIB 19-067 and DVSA emissions data. Regular maintenance greatly reduces occurrence.
The 1.5 CDTi 120 (B16DTR) powered the Corsa F (2018–2023), Crossland (2018–2022), and Grandland (2018–2023). It was also used in Opel equivalents and shared architecture with Peugeot 1.5 BlueHDi under the Stellantis alliance.
Aftermarket ECU tuning is common on the B-16-DTR 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 F 1.5 CDTi 120, expect ~4.8 L/100km combined (59 mpg UK). Highway driving can achieve ~4.1 L/100km (69 mpg UK), while city use may rise to ~5.9 L/100km (48 mpg UK), depending on traffic and maintenance.
Yes. The B16DTR is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally robust if serviced correctly with proper oil.
Vauxhall specifies GM dexos2 Gen 2 0W-30 synthetic oil. This is critical for protecting the high-pressure fuel pump and turbo bearings. Oil changes every 15,000 km (or annually) are essential—extended intervals risk pump and chain wear.
