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 compliance.
Fitted to models such as the Corsa F and Crossland—including the 1.2 Turbo D variants—the B12 XHL was engineered for compact urban mobility with strong low‑end torque and low CO₂ output. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), meeting Euro 6d‑TEMP standards throughout its production run.
One documented concern is high‑pressure fuel pump (HPFP) drive wear due to insufficient lubrication under frequent short‑trip operation, highlighted in Vauxhall Technical Service Bulletin TSB‑19‑41. This is often linked to fuel dilution from incomplete combustion cycles or use of non‑EN 590 diesel. Later service procedures mandated revised pump drive components and stricter fuel quality adherence.
Production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/9456).
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 DOHC three-cylinder layout delivers brisk low-RPM torque ideal for city driving but requires strict adherence to 15,000 km oil change intervals with ACEA C2/C3 0W‑30 oil to protect the CP4.2 high-pressure fuel pump. Short-trip driving increases fuel dilution risk, accelerating HPFP wear. Only EN 590 ultra-low-sulfur diesel (ULSD) must be used; biodiesel blends above B7 may degrade injector seals. The chain-driven timing system is durable but sensitive to oil quality—extended intervals risk guide wear. DPF regeneration cycles are frequent in urban use; regular highway runs are recommended to maintain filter health.
Oil Specs: Requires ACEA C2/C3 (0W‑30) specification (Vauxhall Owner Manual 2019). BMW Longlife-04 is not compatible.
Emissions: Euro 6d-TEMP certification applies to all 2018–2023 B12 XHL units (VCA Type Approval #VCA/EMS/9456). No earlier emissions variants produced.
Power Ratings: Measured under ISO 1585 standards. Output verified on dynamometer per Vauxhall PT‑2020.

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front face of the cylinder block adjacent to the timing cover (Vauxhall TIS V18‑445). The 8th VIN digit indicates engine displacement ('2' for 1.2L). B12 XHL units feature a black aluminium valve cover with “1.2D” embossed and a Bosch CP4.2 high-pressure fuel pump mounted on the right side. Critical differentiation from B12XEL (petrol): B12 XHL is diesel with DPF and EGR; B12XEL is turbo petrol with no aftertreatment. ECU part numbers beginning with “B12XHL” or “EB2DT” confirm application.
The B12 XHL's primary reliability risk is high-pressure fuel pump (HPFP) drive wear, with elevated incidence in urban-driven or short-trip examples. Vauxhall internal service data from 2021 indicated a notable share of pre-2020 engines requiring HPFP replacement before 80,000 km, while UK DVSA records show DPF-related advisories as common MOT items. Fuel quality and driving pattern make proper maintenance critical.
