The Vauxhall A 14 XER is a 1,399 cc, inline‑four naturally aspirated petrol engine produced between 2005 and 2013. It features a double overhead camshaft (DOHC), four valves per cylinder, and sequential multi‑point fuel injection. Output ranges from 74–77 kW (101–105 PS) with torque between 130–136 Nm, providing responsive urban performance with improved fuel efficiency over earlier SOHC units.
Fitted to compact models such as the Corsa C, Corsa D, and Meriva A, the A 14…
Production years 2005–2008 meet Euro 4 standards; 2009–2013 models meet Euro 5 depending on market .
The Vauxhall A 14 XER is a 1,399 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and MPVs (2005–2013). It combines DOHC 16‑valve architecture with sequential multi‑point fuel injection to deliver responsive low‑to‑mid range torque and smooth urban drivability. Designed to meet Euro 4 and Euro 5 emissions standards, it balances performance, efficiency, and regulatory compliance through precise electronic engine management.

The Vauxhall A 14 XER was used across Vauxhall's T-Car and Zafira A platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Meriva and modified intake manifolds in the Corsa D—and from 2009 the updated timing tensioner design improved reliability, creating minor 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 A 14 XER is generally reliable and can exceed 150,000 km with proper care. Early units (pre-2009) are prone to timing tensioner wear, but later versions are more durable. Regular oil changes with correct 5W‑30 spec oil and use of quality fuel are essential for longevity.
Common issues include timing chain tensioner wear (early builds), intake valve carbon buildup, throttle body contamination, and camshaft position sensor failure. These are documented in Vauxhall Engineering Bulletins EB‑07‑18 and service manuals from the 2000s.
The A 14 XER powered the Corsa C (2005–2006), Corsa D (2006–2013), and Meriva A (2005–2010) as the 1.4i 16v petrol variant. It was never licensed to other manufacturers. All applications used transverse front-wheel-drive mounting.
Aftermarket ECU tuning is common on the A-14-XER 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.
Typical consumption is ~7.2 L/100km (city) and ~5.4 L/100km (highway), or about 39–44 mpg UK combined. Well-maintained examples achieve 38–46 mpg (UK) on mixed routes, depending on driving style and fuel quality.
Yes. The A 14 XER is an interference engine. If the timing chain jumps or fails, the pistons will contact the valves, causing severe internal damage. Any timing rattle must be addressed immediately.
Vauxhall specifies SAE 5W‑30 oil meeting ACEA A3/B4 or GM‑LL‑A‑025 standards. Full synthetic is recommended. Change every 15,000 km or annually. Correct oil is critical for timing chain and tensioner longevity.
