The Vauxhall B13DTN is a 1,248 cc, inline‑three turbo‑diesel engine produced between 2015 and 2021. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 66 kW (90 PS) and 200 Nm of torque, providing responsive low — end pull for compact vehicle applications.
Fitted to models such as the Corsa E, Adam, and Karl—including the 1.3 CDTi variants—the B13DTN was engineered for urban e…
Production years 2015–2021 meet Euro 6 standards .
The Vauxhall B13DTN is a 1,248 cc inline‑three turbo‑diesel engineered for subcompact models (2015–2021). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient urban driving. Designed to meet Euro 6 standards, it balances everyday performance with emissions compliance.

The Vauxhall B13DTN was used across Vauxhall's Corsa E, Adam, and Karl platforms with transverse mounting and co-developed with PSA (Peugeot/Citroën) under the joint Euro 6 diesel program. This engine received platform-specific adaptations—revised engine mounts in the Adam and modified intake manifolds in the Karl—and from 2018 the updated camshaft design improved HPFP durability, creating 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 B13DTN offers good urban efficiency and low-end torque, but early models (2015–2017) are prone to HPFP cam lobe wear. Post-2018 revisions improved durability. With strict adherence to Dexos2 oil, EN 590 diesel, and timely servicing, later examples can be dependable beyond 130,000 km.
Top issues include HPFP camshaft lobe wear, DPF regeneration failures from short trips, EGR cooler clogging/leaks, and turbo actuator sticking. These are documented in Vauxhall service bulletins and DVSA MOT data, especially for city-driven vehicles.
The B13DTN powered the Corsa E (1.3 CDTi), Adam (1.3 CDTi), and Karl (1.3 CDTi) from 2015–2021. It was also used in Opel Corsa E and shared with PSA under co-development. All are Euro 6 compliant with diesel particulate filters.
Aftermarket ECU tuning is common on the B-13-DTN 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.
In a Corsa E 1.3 CDTi, expect ~3.8 L/100km combined (74 mpg UK). City driving yields ~4.5 L/100km, highway ~3.3 L/100km. Real-world economy depends heavily on driving style and DPF regeneration frequency—short trips reduce efficiency.
Yes. The B13DTN is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. While chain failures are rare, any unusual noises should be investigated immediately.
Vauxhall specifies GM Dexos2 5W-30 synthetic oil. This is critical for HPFP cam lobe protection and DPF compatibility. Never use non-Dexos2 oils, as incorrect additives can accelerate wear or cause DPF clogging.
