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…
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 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.
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.
Analysis derived from Vauxhall technical bulletins (2018–2023) and UK DVSA failure statistics (2019–2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The D 15 SFL offers strong performance and good efficiency, but early models (2018–2020) had camshaft HPFP drive lobe wear concerns. Later revisions (post-2021) improved camshaft durability. With regular servicing and GM dexos2 oil, well-maintained examples can exceed 150,000 km without major issues.
The most frequent issues are camshaft HPFP drive lobe wear, turbo wastegate sticking, GPF clogging from short trips, and oil leaks from the cam cover. These are documented in Vauxhall service bulletins, particularly SIB 12 068.
This 1.5L turbo petrol engine was used in the Corsa F (2019–2024), Crossland (2018–2024), and Mokka (2020–2024). All variants are badged '1.5 Turbo' and comply with Euro 6d emissions standards from launch.
Yes. ECU remaps typically yield +15–25 kW safely on stock hardware, as the turbo and internals tolerate moderate torque increases. Stage 1 tuning is common on Corsa and Mokka. However, aggressive tuning without supporting fuel system upgrades may accelerate camshaft and HPFP wear.
In a Corsa 1.5 Turbo, typical consumption is ~6.5 L/100km (city) and ~4.8 L/100km (highway), or about 48 mpg UK combined. Real-world mixed driving usually returns 45–52 mpg (UK), depending on driving style and model weight.
Yes. The D 15 SFL is an interference engine. If the timing chain fails (though rare due to robust design), piston-to-valve contact can cause catastrophic damage. However, the chain is designed as maintenance-free and rarely fails if oil is changed regularly.
Vauxhall specifies GM dexos2 (SAE 5W-30) synthetic oil. Always use this exact specification to ensure camshaft and turbo longevity, and change every 15,000 km or 12 months—whichever comes first.
