The Vauxhall B14 XE is a 1,399 cc, inline‑three turbocharged petrol engine produced between 2018 and 2023. It features a double overhead camshaft (DOHC), 12‑valve configuration with direct fuel injection and variable valve timing, delivering 103 kW (140 PS) and 240 Nm of torque. The all‑aluminium construction reduces weight while maintaining rigidity, and the integrated exhaust manifold enables rapid catalyst light‑off for urban emissions compliance.
Fitted to models such as the Corsa F and Crossland—including the 1.4 Turbo variants—the B14 XE was engineered for responsive urban performance with strong low‑end torque and refined high‑speed cruising. Emissions compliance was achieved through gasoline particulate filtration (GPF), exhaust gas recirculation (EGR), and precise lambda control, meeting Euro 6d‑TEMP standards throughout its production run.
One documented concern is high‑pressure fuel pump (HPFP) drive wear under sustained high‑load conditions, highlighted in Vauxhall Technical Service Bulletin TSB‑19‑28. This is often linked to marginal oil film strength at the pump drive pinion during aggressive driving or extended oil change intervals. Later service procedures mandated revised pump drive components and stricter oil specifications.
Production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/9321).
The Vauxhall B14 XE is a 1,399 cc inline‑three turbocharged petrol engine engineered for subcompact hatchbacks and crossovers (2018–2023). It combines direct injection with variable valve timing and a low-inertia turbocharger to deliver brisk urban acceleration and smooth highway performance. Designed to meet Euro 6d-TEMP emissions standards, it integrates a gasoline particulate filter with lightweight architecture.

The DOHC three-cylinder layout delivers responsive torque ideal for city driving but requires strict adherence to 15,000 km oil change intervals with ACEA C2/C3 0W‑20 oil to protect the high-pressure fuel pump drive. Aggressive driving or extended intervals reduce oil film strength at the HPFP drive pinion, accelerating wear. Only EN 228 unleaded petrol must be used; ethanol blends above E10 may degrade injector seals. The chain-driven timing system is durable but sensitive to oil quality—extended intervals risk guide wear. The GPF requires periodic highway driving to maintain regeneration cycles.
Oil Specs: Requires ACEA C2/C3 (0W‑20) specification (Vauxhall Owner Manual 2019). Non-low-SAPS oils are not compatible.
Emissions: Euro 6d-TEMP certification applies to all 2018–2023 B14 XE units (VCA Type Approval #VCA/EMS/9321). No earlier emissions variants produced.
Power Ratings: Measured under ISO 1585 standards. Output verified on dynamometer per Vauxhall PT‑2020.

The Vauxhall B14 XE 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 V18‑334). The 8th VIN digit indicates engine displacement ('4' for 1.4L). B14 XE units feature a black aluminium valve cover with “1.4T” embossed and a Bosch HDP5 high-pressure fuel pump mounted on the right side. Critical differentiation from B12XEL: B14 XE is 1.4L with GPF and direct injection; B12XEL is 1.2L with port injection and no GPF. ECU part numbers beginning with “B14XE” confirm application.
The B14 XE's primary reliability risk is high-pressure fuel pump (HPFP) drive wear, with elevated incidence in aggressively driven or poorly maintained examples. Vauxhall internal service data from 2021 indicated a notable share of pre-2020 engines requiring HPFP replacement before 90,000 km, while UK DVSA records show GPF-related advisories as common MOT items. Driving style and oil quality make proper maintenance critical.
