Production years 2018–2023 meet Euro 6d standards .
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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

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.
Aftermarket ECU tuning is common on the A-30-XH platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
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.
