The Vauxhall A30XH 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 96 kW (130 PS) and 230 Nm of torque, providing brisk low — end response for compact vehicle applications.
Fitted to models such as the Corsa F, Crossland X, and Grandland X—including the 1.2 Turbo variants—the A30XH was engineered for responsiv…
Production years 2018–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/7890).
The Vauxhall A30XH 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 Vauxhall A30XH was used across Vauxhall's Corsa F, Crossland X, and Grandland X 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.
The A30XH'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.
Analysis derived from Vauxhall technical bulletins (2019–2023) and UK DVSA failure statistics (2020–2023). 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 A30XH offers strong low-end torque and good efficiency, but early models (2018–2020) are prone to HPFP cam lobe wear. Post-2021 revisions improved durability. With strict adherence to Dexos1 Gen 3 oil, RON 95+ petrol, and timely servicing, later examples can be dependable beyond 150,000 km.
Top issues include HPFP camshaft lobe wear, GPF regeneration failures from short trips, intake valve coking, and turbo wastegate sticking. These are documented in Vauxhall service bulletins and DVSA MOT data, especially for urban-driven vehicles.
The A30XH powered the Corsa F (1.2 Turbo), Crossland X (1.2 Turbo), and Grandland X (1.2 Turbo) from 2018–2023. It was also used in Opel Corsa F and shared with PSA under co-development. All are Euro 6d compliant with gasoline particulate filters.
Yes. Stage 1 ECU remaps typically yield +15–20 kW safely, as the turbo and internals tolerate moderate torque increases. However, HPFP and camshaft reliability may suffer without supporting upgrades. Tuning is not recommended on pre-2021 engines without camshaft inspection.
In a Corsa F 1.2 Turbo, expect ~5.4 L/100km combined (52 mpg UK). City driving yields ~6.5 L/100km, highway ~4.5 L/100km. Real-world economy depends heavily on driving style and GPF regeneration frequency—short trips reduce efficiency.
Yes. The A30XH is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. While chain failures are rare, any unusual noises should be investigated immediately.
Vauxhall specifies GM Dexos1 Gen 3 0W-20 synthetic oil. This is critical for HPFP cam lobe protection and GPF compatibility. Never use non-Dexos1 oils, as incorrect additives can accelerate wear or cause GPF clogging.
