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 performance and efficient motorway cruising. Emissions compliance was achieved through a close‑coupled three‑way catalytic converter and cooled exhaust gas recirculation (EGR), enabling Euro 6d‑TEMP compliance across all production years.
One documented concern is high‑pressure fuel pump (HPFP) wear under sustained high load, highlighted in Vauxhall Service Bulletin PI0872. This is often linked to marginal lubricity in low‑sulfur fuels and thermal stress during repeated short trips. From mid‑2020, Vauxhall introduced updated HPFP seals and revised calibration to mitigate premature wear.
All production years (2018–2023) meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/5678).
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 turbocharged direct-injection layout provides brisk throttle response but demands strict adherence to 15,000 km oil change intervals using DEXOS2 5W-30 to protect the high-pressure fuel pump and turbo bearings. Fuel must meet EN 228 standards with adequate lubricity; ethanol blends above E10 are not recommended. Short-trip driving increases carbon buildup on intake valves (due to lack of fuel washing), so occasional higher-RPM operation is advised. The front-mounted timing chain is considered lifetime but relies on clean oil; sludge from neglected changes may impair tensioner function. HPFP failures before 80,000 km should prompt inspection per Vauxhall SIB PI0872.
Oil Specs: Requires DEXOS2 5W-30 (ACEA C3) specification (Vauxhall Owner's Manual 2019).
Emissions: Euro 6d-TEMP certification applies to all 2018–2023 D 14 XEL engines (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output assumes RON 95 fuel (Vauxhall TIS Doc. TIS-D14XEL-04).

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.
Locate the engine code stamped on the front timing cover near the crank pulley (Vauxhall TIS TIS-D14XEL-06). The 7th VIN digit for D 14 XEL applications is 'D'. All units feature black valve covers with integrated coil packs and a Honeywell TD025 turbo with a single wastegate actuator. Critical differentiation from earlier 1.4T (B14XFT): D 14 XEL uses direct injection only (no port injectors) and has a different HPFP mounting flange. Service parts for HPFP (pre- and post-06/2020) are not interchangeable due to seal material changes per Vauxhall SIB PI0872.
The D 14 XEL's primary reliability risk is high-pressure fuel pump (HPFP) wear under repeated short-trip use. Vauxhall internal field data (2021) indicated elevated HPFP replacement rates before 80,000 km in urban fleets, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Thermal cycling and marginal fuel lubricity make DEXOS2 oil and fuel quality critical.
