The Vauxhall B14XFL is a 1,199 cc, inline‑three turbo‑petrol engine produced between 2018 and 2023. It features direct fuel injection, a single-scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 103 kW (140 PS) and 245 Nm of torque, providing brisk low-end response for compact vehicle applications.
Fitted to models such as the Corsa F, Crossland, and Grandland—including the 1.2 Turbo variants—the B14XFL was engineered for responsive urban driving and relaxed motorway cruising. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and three-way catalytic converter, meeting Euro 6d standards across its production run.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the camshaft, highlighted in Vauxhall Service Bulletin 19‑058. This issue is often linked to marginal lubrication during cold starts and extended oil change intervals. From 2021 onward, revised camshaft and HPFP materials were introduced to improve durability.
Production years 2018–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/7891).
The Vauxhall B14XFL is a 1,199 cc inline‑three turbo‑petrol engineered for subcompact and compact models (2018–2023). It combines direct injection with a single-scroll turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 6d standards, it balances everyday performance with emissions compliance.

The compact three-cylinder layout delivers strong low-end torque ideal for city driving but requires strict adherence to 15,000 km oil change intervals using GM Dexos1 Gen 3 (0W-20) to prevent HPFP cam lobe wear. The Bosch HDP6 fuel system demands high-quality RON 95+ petrol to avoid injector coking. Extended idling or short-trip driving increases GPF soot accumulation, risking regeneration failures. Post-2021 engines feature updated camshaft surface treatment per Vauxhall SIB 19-058; pre-2021 units benefit from proactive HPFP inspection. Cooled EGR reduces knock tendency but requires periodic cleaning to maintain efficiency.
Oil Specs: Requires GM Dexos1 Gen 3 (0W-20) specification (Vauxhall SIB 19-058). Meets ACEA C5 but with OEM-specific additive limits.
Emissions: Euro 6d certification applies to all production years 2018–2023 (VCA Type Approval #VCA/EMS/7891).
Power Ratings: Measured under SAE J1349 standards. Output verified on Corsa F 1.2 Turbo 140 (VIN 8th digit 'L') per Vauxhall TIS V33‑002.

The Vauxhall B14XFL was used across Vauxhall's Corsa F, Crossland, and Grandland platforms with transverse mounting and co-developed with PSA (Peugeot/Citroën) under the joint Euro 6d petrol program. This engine received platform-specific adaptations—revised engine mounts in the Grandland and modified intake manifolds in the Corsa—and from 2021 the updated camshaft design improved HPFP durability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Vauxhall TIS V32‑1485). The 8th VIN digit indicates engine family ('L' for B14XFL). Pre-2021 models use a standard camshaft surface finish; post-2021 units have nitrided camshaft lobe treatment. Critical differentiation from B14XEL: B14XFL is higher-output (140 PS) with reinforced internals, while B14XEL is 130 PS. Service parts for fuel system require production date verification—HPFP kits for engines before 03/2021 are incompatible with later units due to camshaft material revision (Vauxhall SIB 19‑058).
The B14XFL's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the camshaft in early builds, with elevated incidence in vehicles using non-Dexos1 oil or exceeding service intervals. Vauxhall internal data from 2021 indicated a notable share of pre-2021 engines requiring camshaft replacement before 80,000 km, while UK DVSA records show increased GPF-related MOT failures in urban-driven examples. Short-trip cycles and poor oil quality accelerate wear, making oil specification and interval adherence critical.
