The Vauxhall D 15 SFL is a 1,490 cc, inline‑three turbocharged petrol engine produced between 2018 and 2024. It features a DOHC 12‑valve layout, gasoline direct injection, and a single‑scroll turbocharger, delivering 107 kW (145 PS) and 225 Nm of torque. Variable valve timing and a lightweight aluminium block enable responsive performance and improved thermal efficiency.
Fitted to models such as the Corsa F, Crossland, and Mokka—including the 1.5 Turbo variants—the D 15 SFL was engineered for agile urban driving and relaxed motorway cruising. Emissions compliance was achieved through a close‑coupled three‑way catalytic converter, particulate filter (GPF), and cooled exhaust gas recirculation (EGR), allowing full Euro 6d compliance from launch.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the camshaft, highlighted in Vauxhall Service Bulletin 12‑068. This is often linked to infrequent oil changes or use of non‑dexos2‑approved lubricants. In 2021, Vauxhall introduced a revised camshaft material specification and updated HPFP calibration to mitigate wear.
Production years 2018–2024 meet Euro 6d standards across all markets (VCA UK Type Approval #VCA/EMS/8912).
The Vauxhall D 15 SFL is a 1,490 cc inline‑three turbocharged petrol engineered for subcompact and compact models (2018–2024). It combines gasoline direct injection with a single‑scroll turbocharger to deliver brisk low‑end response and smooth power delivery. Designed to meet Euro 6d emissions standards, it balances urban agility with fuel efficiency and regulatory compliance.

The compact turbocharged layout provides responsive acceleration suited to city and highway use, but requires strict adherence to 15,000 km or 12-month oil change intervals using GM dexos2 (5W-30) to protect the camshaft HPFP drive lobe and turbo bearing. The Bosch HDP6 fuel system demands EN 228-compliant 95 RON (or higher) petrol to prevent injector coking and HPFP wear. Short-trip driving may accelerate carbon buildup on intake valves due to the absence of fuel-wash in direct-injection systems. Post-2021 engines include a nitrided camshaft per Vauxhall SIB 12 068 to improve HPFP drive durability.
Oil Specs: Requires GM dexos2 (5W-30) specification (Vauxhall SIB 12 068). Equivalent to ACEA C5 but with GM-specific additive limits.
Emissions: Euro 6d certification applies to all 2018–2024 models (VCA Type Approval #VCA/EMS/8912). No market-specific deviations.
Power Ratings: Measured under SAE J1349 standards. Full 107 kW output requires 95 RON minimum fuel (Vauxhall TIS Doc. V31620).

The Vauxhall D 15 SFL was used across Vauxhall's Corsa F, Crossland, and Mokka platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Mokka for NVH refinement and compact exhaust manifolds in the Corsa F—and from 2021 the Crossland LCI adopted updated camshaft hardware, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block near the timing cover (Vauxhall TIS V31520). The 7th VIN digit indicates engine family ('D' for D15 series). All D 15 SFL units feature a black plastic cam cover with '1.5 Turbo' badge. Critical differentiation from naturally aspirated D15: D 15 SFL has a visible turbocharger on the exhaust manifold and high-pressure fuel rail. Camshaft part numbers changed in 2021—pre-2021 camshafts (GM 55598760) are not interchangeable with post-2021 units (GM 55598761) due to nitriding treatment updates (Vauxhall SIB 12 068).
The D 15 SFL's primary reliability risk is camshaft HPFP drive lobe wear in early builds, with elevated incidence in vehicles using non‑dexos2 oil or extended service intervals. Vauxhall internal data from 2022 indicated a measurable increase in camshaft‑related warranty claims before 80,000 km, while UK DVSA records show no significant GPF‑related MOT failures linked to this engine. Oil quality and change discipline make camshaft longevity critical.
