The Vauxhall B16LER is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 2004 and 2011. It features a dual overhead camshaft (DOHC) 16‑valve layout with sequential multi‑point fuel injection. In standard form it delivered 77 kW (105 PS) at 6,000 rpm and 150 Nm of torque at 4,000 rpm, providing responsive urban performance and smooth motorway cruising.
Fitted to models such as the Corsa C, Tigra B, and Meriva A—including the 1.6 Life, 1.6 Club, and 1…
All production years 2004–2011 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5128).
The Vauxhall B16LER is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks, coupés, and MPVs (2004–2011). It combines DOHC 16‑valve architecture with sequential multi‑point fuel injection to deliver responsive low‑to‑mid range power and dependable daily driving. Designed to meet Euro 4 emissions standards, it balances drivability with serviceability.

The Vauxhall B16LER was used across Vauxhall's T300/Z30 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Meriva A and modified airbox routing in the Corsa C—and from 2007 the facelifted Tigra B models retained the same engine code but updated ECU calibrations for OBD‑II compliance, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
The B16LER's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in high-mileage vehicles used primarily for short urban trips. Vauxhall internal field data from 2006 indicated cam wear in a notable subset of engines exceeding 120,000 km without strict oil maintenance, while UK DVSA MOT records show secondary failures linked to misfire-related emissions faults. Cold-start cycles without full warm-up increase cam stress, making oil quality and change interval adherence critical.
Analysis derived from Vauxhall technical bulletins (2004–2008) and UK DVSA failure statistics (2010–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The B16LER is generally dependable with proper maintenance, but early camshaft wear can occur in high-mileage examples with infrequent oil changes. Using GM‑LL‑A‑025 oil and adhering to 10,000 km service intervals greatly reduces risk. Well-maintained units often exceed 200,000 km without major issues.
Exhaust cam lobe wear is the most serious issue, followed by throttle body carbon buildup, coolant sensor drift, and cam cover oil leaks. These are documented in Vauxhall TSBs and commonly observed in UK MOT failure data. Regular servicing mitigates most concerns.
The B16LER powered the Corsa C (2004–2011), Tigra B (2004–2009), and Meriva A (2004–2010) in 1.6 Life, Club, SXi, and Enjoy trims. It was exclusive to Vauxhall/Opel and not licensed to other manufacturers. All variants meet Euro 4 emissions.
Modest gains are possible via ECU remap (+5–8 kW) and induction/exhaust upgrades, but the engine lacks forced induction. Significant tuning is limited by the stock internals and fuel system. Most owners prioritize reliability over performance due to the engine’s age and design.
In a Corsa C 1.6, expect ~7.7 L/100km (city) and ~5.2 L/100km (highway), or about 43 mpg UK combined. Real-world mixed driving typically yields 38–45 mpg (UK), depending on condition and driving style. Economy is competitive for its era.
Yes. The B16LER is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause severe internal damage. However, the chain is robust and rarely fails if maintained; no widespread timing-related failures are documented.
Vauxhall specifies SAE 10W‑40 or 5W‑30 synthetic oil meeting GM‑LL‑A‑025. Always use a quality oil and change every 10,000 km or 12 months to protect the camshafts and maintain engine longevity.
