The Vauxhall B12 XHL (also designated EB2DT by PSA/Stellantis) is a 1,199 cc, inline‑three turbo‑diesel engine produced between 2018 and 2023. It features a double overhead camshaft (DOHC), 12‑valve configuration with high‑pressure common‑rail direct injection, delivering 66 kW (90 PS) and 230 Nm of torque. The aluminium block with cast‑iron liners and integrated exhaust manifold reduce weight while enabling rapid catalyst light‑off for urban emissions complian…

The Vauxhall B12 XHL (EB2DT) is a 1,199 cc inline‑three turbo‑diesel engineered for subcompact hatchbacks and crossovers (2018–2023). It combines high-pressure common-rail injection with a low-inertia turbocharger to deliver responsive urban drivability and low CO₂ emissions. Designed to meet Euro 6d-TEMP standards, it integrates advanced aftertreatment with lightweight architecture.

The Vauxhall B12 XHL (EB2DT) was used across Vauxhall's Corsa F and Crossland platforms with transverse mounting and shared PSA/Stellantis architecture. This engine received platform-specific adaptations—revised engine mounts in the Crossland for NVH control and modified air intake routing in the Corsa F—and from 2021 the WLTP-compliant updates included minor ECU calibrations for RDE compliance, 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 B12 XHL is compact and efficient but sensitive to driving patterns and fuel quality. Early models (2018–2019) are more prone to HPFP wear under short-trip use, while post-2020 units with updated components are more resilient. Regular oil changes with ACEA C2/C3 0W‑30 and use of EN 590 diesel greatly improve longevity.
High-pressure fuel pump wear, DPF regeneration issues, EGR cooler leaks, and timing chain guide wear. These are documented in Vauxhall TSB‑19‑41 and observed in urban-driven fleets. Most issues stem from operational factors rather than inherent design flaws.
Exclusively the Corsa F (2019–2023) and Crossland (2018–2023) in 1.2 Turbo D 90 PS trim. All are Euro 6d-TEMP-compliant and share PSA/Stellantis EB2DT architecture. No cross-brand applications outside Stellantis group are documented for this diesel variant.
Limited tuning potential. ECU remapping may yield +5–8 kW, but the CP4.2 pump and three-cylinder bottom end are not designed for significant increases. Most owners avoid tuning due to HPFP reliability concerns and minimal real-world benefit in urban driving.
Typical consumption is ~4.8 L/100km (city) and ~3.6 L/100km (highway), or about 59 mpg UK combined in a Corsa 1.2 Turbo D. Real-world figures range 52–63 mpg (UK) depending on driving style, DPF status, and route type.
Yes. The B12 XHL is an interference engine. If the timing chain fails or jumps, pistons will contact open valves, causing severe internal damage. However, the chain system is generally durable with correct oil maintenance.
Vauxhall specifies 0W‑30 oil meeting ACEA C2 or C3 standards. BMW Longlife-04 or non-low-SAPS oils are not compatible. Change every 15,000 km or annually to protect the HPFP and timing components.
