The Vauxhall D 14 XEL is a 1,399 cc, inline‑four turbo‑petrol engine produced between 2018 and 2023. It features direct fuel injection, dual overhead camshafts (DOHC), and a single‑scroll turbocharger. In standard form it delivers 110 kW (150 PS) and 235 Nm of torque, with strong low‑rpm response for everyday drivability.
Fitted to models such as the Astra K, Crossland X, and Grandland X—including the 1.4 Turbo variants—the D 14 XEL was engineered for responsive urban per…
All production years (2018–2023) meet Euro 6d-TEMP standards .
The Vauxhall D 14 XEL is a 1,399 cc inline‑four turbo‑petrol engineered for compact and crossover models (2018–2023). It combines gasoline direct injection with a single‑scroll turbocharger to deliver responsive low‑end torque and refined highway performance. Designed to meet Euro 6d-TEMP, it balances performance with strict emissions control.

The Vauxhall D 14 XEL was used across Vauxhall's Astra K, Crossland X, and Grandland X platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Grandland X for NVH control and modified airbox routing in the Crossland X—and from 2020 the Astra K LCI adopted updated HPFP hardware, creating minor service part distinctions. 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 D 14 XEL offers strong performance and refinement, but early units (2018–mid-2020) had HPFP reliability concerns under urban use. Later revisions improved pump durability. With proper maintenance—especially using DEXOS2 5W-30 oil and quality fuel—most engines exceed 200,000 km without major issues.
Top issues include high-pressure fuel pump wear, intake valve carbon buildup (due to direct injection), turbo wastegate rattle, and coolant leaks from the plastic thermostat housing. HPFP and thermostat problems are addressed in Vauxhall service bulletins PI0872 and TIS-D14XEL-07.
The D 14 XEL powered the Astra K (2018–2023), Crossland X (2018–2022), and Grandland X (2018–2021) in 1.4 Turbo 150 PS form. It was not used in commercial vehicles or licensed to other manufacturers. All applications are transverse FWD or AWD layouts.
Aftermarket ECU tuning is common on the D-14-XEL 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 an Astra 1.4 Turbo (150 PS), expect ~7.2 L/100km (city), ~5.1 L/100km (highway), or ~58 mpg UK combined. Real-world mixed driving typically returns 48–55 mpg UK. Economy suffers with short trips due to extended warm-up enrichment and carbon buildup.
Yes. The D 14 XEL is an interference engine. If the timing chain fails (extremely rare due to front-mounted design), piston-to-valve contact will cause catastrophic damage. However, the chain is designed for life-of-engine service with proper oil maintenance.
Vauxhall specifies DEXOS2 5W-30 (ACEA C3) synthetic oil. This low-SAPS formulation protects the turbo, HPFP, and emissions systems. Change intervals should not exceed 15,000 km or 12 months, especially with urban driving.
