The Vauxhall D 14 XFT is a 1,398 cc, inline‑four turbo‑petrol engine produced from 2020 onward. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 230 Nm of torque, with variable valve timing enhancing responsiveness across the rev range.
Fitted to models such as the Astra K and Grandland, the D 14 XFT was engineered for compact‑car performance, offering brisk accelera…

The Vauxhall D 14 XFT is a 1,398 cc inline‑four turbo‑petrol engineered for compact and mid‑size models (2020–present). It combines direct injection with a twin‑scroll turbocharger to deliver responsive mid‑range torque and efficient highway cruising. Designed to meet Euro 6d standards, it balances sporty performance with low emissions and fuel consumption.

The Vauxhall D 14 XFT was used across Vauxhall's EMP2 platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Grandland and revised intake routing in the Astra K—and from 2022 the facelifted Astra adopted updated engine mounts and GPF substrate density, 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 XFT is generally robust when maintained properly. Key concerns include high-pressure fuel pump wear beyond 80,000 km and GPF clogging from short trips. Using EN 228-compliant fuel and DEXOS2 oil, plus occasional highway driving, significantly improves longevity. No widespread timing chain issues have been reported.
Top issues are high-pressure fuel pump wear, GPF overloading from urban driving, turbo actuator faults, and intake valve carbon buildup. These are documented in Vauxhall service bulletins like SIB 01 22 09. Most are preventable with correct fuel, oil, and driving habits.
The D 14 XFT powers the Astra K (2020–present) and Grandland (2020–present) in 150 PS form. It is exclusive to Vauxhall within Stellantis and is not shared with Peugeot or Citroën in this configuration. All units meet Euro 6d emissions standards.
Aftermarket ECU tuning is common on the D-14-XFT 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.
Official WLTP figures range from 5.8–6.5 L/100km (43–49 mpg UK) depending on model and trim. Real-world mixed driving typically yields 6.5–7.5 L/100km (38–43 mpg UK). Highway efficiency can reach 5.5 L/100km (51 mpg UK), while city driving may exceed 8.0 L/100km.
Yes. The D 14 XFT is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain design has shown high durability in service, with no major recalls to date.
Vauxhall specifies DEXOS2 0W‑20 synthetic oil. This low-SAPS formulation protects the GPF and turbocharger. Oil changes are required every 15,000 km or 12 months. Using non-DEXOS2 oil may void warranty and accelerate GPF clogging.
