The Vauxhall B16XER is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 2018 and 2023. It features port fuel injection, dual overhead camshafts (DOHC), and variable valve timing on the intake camshaft. In standard form it delivered 82 kW (112 PS) with 155 Nm of torque, engineered for urban efficiency and low — cost ownership.
Fitted to models such as the Corsa F, Crossland, and Grandland, including the 1.6i 112 variants, the B16XER was designed as…
Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d depending on market .
The Vauxhall B16XER is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for subcompact and compact crossovers (2018–2023). It combines port fuel injection with variable intake cam timing to deliver smooth low-end response and dependable urban efficiency. Designed to meet Euro 6d TEMP and Euro 6d emissions standards, it prioritises cost-effective ownership without compromising drivability.

The Vauxhall B16XER was used across Vauxhall's Corsa F, Crossland, and Grandland platforms with transverse mounting and no external licensing. This engine received platform-specific calibrations—revised idle logic in the Corsa and enhanced NVH tuning in the Grandland—and from 2020 the Euro 6d-compliant variants featured updated piston ring packs and valve stem seals, 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 B16XER offers dependable performance and low running costs, but early models (2018–2020) had oil consumption concerns. Post-2020 revisions with updated piston rings and seals improved durability. With proper maintenance—especially using GM Dexos1 Gen 2 oil and avoiding excessive short trips—these engines can reliably exceed 180,000 km.
Top issues include excessive oil consumption (early builds), catalytic converter degradation from oil burning, timing chain tensioner wear, and throttle body carbon buildup. These are documented in Vauxhall service bulletins PI1173 and TIS updates.
The B16XER powered the Corsa F (2018–2023), Crossland (2018–2023), and Grandland (2018–2023) in 1.6i 112 variants. All are transverse-mounted compact applications meeting Euro 6d TEMP or Euro 6d standards depending on year.
Limited potential. As a naturally aspirated port-injected engine, power gains are modest—typically +5–8 kW with intake/exhaust upgrades and ECU remap. Aggressive tuning is not recommended due to marginal internal strength and lack of forced induction.
Good for its class. In a Corsa 1.6i 112, expect ~6.2 L/100km (46 mpg UK) combined. Real-world mixed driving typically returns 40–45 mpg UK (6.3–7.1 L/100km), depending on driving style and conditions.
Yes. The B16XER is an interference design. Timing chain failure—though rare—can cause piston-to-valve contact and catastrophic damage. The front-mounted chain is robust with proper oil maintenance.
GM Dexos1 Gen 2-approved 5W‑30 synthetic oil is mandatory. This high-shear-stability formulation protects piston rings, valve stem seals, and timing components. Change intervals should not exceed 15,000 km or 12 months.
