The Vauxhall D12XHL (also known as PSA EB2ADT) is a 1,199 cc, inline‑three turbocharged diesel engine introduced in 2018. It features common‑rail direct injection, dual overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). In standard form it delivers 74 kW (100 PS) and 250 Nm of torque, offering strong low‑end pull in compact applications.
Fitted to models such as the Crossland and Grandland, the D12XHL was engineered for urban efficiency, refinemen…
All production years 2018–present meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/4103).
The Vauxhall D12XHL (EB2ADT) is a 1,199 cc inline‑three turbocharged diesel engineered for subcompact SUVs (2018–present). It combines Bosch common‑rail injection with a variable geometry turbocharger to deliver strong low‑rpm torque and urban drivability. Designed to meet Euro 6d emissions standards, it integrates AdBlue SCR and DPF systems for regulatory compliance.

The Vauxhall D12XHL (EB2ADT) was used across Vauxhall's EMP2-derived SUV platforms with transverse mounting and co-developed with Stellantis (PSA). This engine received platform-specific adaptations—revised engine mounts in the Grandland and enhanced cooling routing in the Crossland—and from mid‑2021 the updated camshaft design improved HPFP durability, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
The D12XHL's primary reliability risk is HPFP drive lobe wear on the intake camshaft in pre-mid‑2021 builds, with elevated incidence in frequent short‑trip or high‑load urban use. Vauxhall internal data (2022) indicated camshaft replacements in ~7% of early Crosslands before 60,000 km, while UK DVSA records show minimal SCR-related MOT failures due to robust AdBlue system logic. Cold starts and poor fuel quality accelerate cam lobe degradation, making oil grade and service adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D12XHL is generally robust when maintained properly, but early models (2018–2021) have a known HPFP cam lobe wear issue. Mid‑2021 revisions improved camshaft durability. Using EN 590 diesel, DEXOS2 0W‑30 oil, and adhering to service intervals greatly enhances longevity. Many examples exceed 100,000 km with no major issues.
HPFP cam lobe wear (pre‑mid‑2021), AdBlue dosing faults, DPF saturation from short trips, and EGR cooler leaks are the main concerns. These are documented in Vauxhall TSBs. Carbon buildup is less common than in older diesels due to precise injection control.
The D12XHL powers the Crossland (2018–present) and Grandland (2018–present) in the 1.2 Diesel 100 variant. It is shared with Peugeot 2008/3008 and Citroën C3 Aircross as the EB2ADT under Stellantis co-development.
Limited tuning potential. Stage 1 remaps typically yield +10–15 kW (115–120 PS) but accelerate HPFP and cam wear. The CP4.2 pump and cast internals are not designed for high torque increases. Most tuners advise against aggressive remapping due to reliability risks.
Official combined: ~4.3 L/100km (66 mpg UK). Real-world mixed driving typically yields 5–6 L/100km (47–56 mpg UK). Short urban trips can push consumption above 7 L/100km. EN 590 diesel is mandatory for emissions and pump longevity.
Yes. The D12XHL is an interference engine. If the timing chain were to fail (though rare), piston-to-valve contact would cause catastrophic damage. However, the front-mounted chain is durable and designed for life-of-engine service under normal conditions.
Vauxhall specifies DEXOS2 0W‑30 (ACEA C2) synthetic oil. This low-SAPS formulation protects the turbocharger, cam lobes, and aftertreatment systems. Oil changes every 15,000 km or 12 months are critical to prevent HPFP and cam wear.
