The Vauxhall B16DTJ is a 1,496 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a DOHC 16‑valve layout, common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 88 kW (120 PS) at 3,750 rpm and 300 Nm of torque at 1,500 rpm, providing strong low‑end responsiveness ideal for urban and mixed driving conditions.
Fitted to models such as the Astra K, Corsa F, and Crossland X, the B16DTJ was engineered…
All production years 2018–2023 meet Euro 6d-TEMP standards .
The Vauxhall B16DTJ is a 1,496 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2018–2023). It combines Bosch CP4.2 common‑rail injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and urban fuel efficiency. Designed to meet Euro 6d-TEMP emissions standards, it integrates AdBlue SCR technology for NOx control.

The Vauxhall B16DTJ was used across Vauxhall's Astra K, Corsa F, and Crossland X platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Astra K and modified exhaust manifolds in the Crossland X—and from mid‑2020 the Corsa F LCI adopted updated camshaft lobes and pump couplings, 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Generally yes with proper maintenance. Early models (2018–2019) are prone to fuel pump drive wear if used primarily for short trips. Mid-2020 revisions improved camshaft durability. Using correct Dexos2 0W-30 oil, EN 590 diesel, and genuine AdBlue greatly enhances longevity beyond 180,000 km.
Top issues include high-pressure fuel pump coupling wear, AdBlue dosing faults, EGR valve coking, and timing chain tensioner rattle. These are documented in Vauxhall SIB 19‑037 and DVSA MOT data.
The B16DTJ powered the Astra K (2018–2023), Corsa F (2018–2023), and Crossland X (2018–2023) in 1.5 Turbo D variants. It was not used in commercial vehicles or licensed to other manufacturers.
Aftermarket ECU tuning is common on the B-16-DTJ 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 an Astra 1.5 Turbo D, expect ~4.9 L/100km (city) and ~3.7 L/100km (highway), or about 58 mpg UK combined. Real-world mixed driving typically returns 50–60 mpg (UK), depending on condition and driving style.
Yes. The B16DTJ is an interference design. If the timing chain fails, piston-to-valve contact can cause catastrophic damage. However, the chain is generally robust with proper oil maintenance.
GM Dexos2 0W‑30 (ACEA C2/C5) is mandatory. This low-SAPS oil protects the aftertreatment systems and fuel pump drive. Change every 20,000 km or 12 months, whichever comes first, to prevent sludge and component wear.
