The Vauxhall D 14 XER is a 1,399 cc, inline‑four naturally aspirated petrol engine produced between 2010 and 2018. It features dual overhead camshafts (DOHC), 16 valves, and variable valve timing (VVT) on the intake camshaft. In standard form it delivered 74 kW (100 PS) at 6,000 rpm and 130 Nm of torque at 4,400 rpm, providing responsive urban performance with low fuel consumption.
Fitted to models such as the Corsa D, Meriva B, and Adam, the D 14 XER was engineered for compact city driving with an emphasis on refinement and economy. Emissions compliance was achieved through precise electronic throttle control, exhaust gas recirculation (EGR), and a close-coupled three-way catalytic converter, allowing all units to meet Euro 5 standards.
One documented concern is carbon buildup on the intake valves and EGR passages, which can cause rough idling and hesitation. This issue, highlighted in Vauxhall Service Bulletin TIS-10-05-12, is attributed to crankcase ventilation routing and EGR soot accumulation over time. From 2015, revised PCV hoses and updated ECU calibrations were introduced to mitigate the problem.
All production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Vauxhall D 14 XER is a 1,399 cc inline‑four naturally aspirated petrol engine engineered for subcompact and city cars (2010–2018). It combines DOHC architecture with variable intake cam timing to deliver responsive low‑end torque and smooth idle quality. Designed to meet Euro 5 emissions standards, it balances urban drivability with fuel efficiency.

The naturally aspirated design provides linear throttle response ideal for city driving but requires periodic cleaning of the EGR valve and intake manifold to prevent rough idle and hesitation. GM Dexos2 (5W-30) oil is essential to maintain valve train longevity and catalytic converter efficiency. Extended idling or frequent short trips accelerate carbon buildup in the PCV and EGR circuits. The chain-driven valvetrain is generally robust, but oil degradation can increase wear on tensioners. Post-2015 models benefit from updated ECU maps and revised breather hoses per Vauxhall SIB TIS-10-05-12.
Oil Specs: Requires GM Dexos2 (5W-30) specification (Vauxhall SIB TIS-10-05-12). Not interchangeable with older GM-LL-A-025.
Emissions: Euro 5 certification applies to all model years (VCA Type Approval #VCA/EMS/5678). No Euro 6 variants exist.
Power Ratings: Measured under SAE J1349 standards. Output consistent across all applications (Vauxhall TIS Doc. V10‑4421).

The Vauxhall D 14 XER was used across Vauxhall's Corsa D, Meriva B, and Adam platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Meriva for NVH control and compact accessory layout in the Adam—and from 2015 the Corsa D facelift introduced updated ECU calibration and PCV routing, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the exhaust manifold (Vauxhall TIS V10‑4421). The 8th VIN digit indicates engine displacement ('D' for 1.4L). All D 14 XER units feature black plastic cam covers with '1.4' embossed and a single intake cam phaser. Critical differentiation from A14XER: D 14 XER uses Bosch ME7.8 ECU with 16-pin under-hood diagnostic connector; A14XER uses Continental EMS3125 with 24-pin. Service parts for EGR and PCV hoses differ pre/post 2015 due to routing changes (Vauxhall SIB TIS-10-05-12).
The D 14 XER's primary reliability risk is EGR and intake carbon fouling, with elevated incidence in urban stop-start use. Vauxhall internal data from 2014 noted a measurable increase in idle instability complaints on vehicles under 60,000 km in city fleets, while UK DVSA MOT records show EGR-related emissions failures as a recurring cause in Corsa D models. Short-trip driving and infrequent oil changes accelerate deposit formation, making maintenance adherence critical.
Analysis derived from Vauxhall technical bulletins (2010–2016) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
