The Vauxhall B13DTE is a 1,248 cc, inline‑three turbo‑diesel engine produced between 2018 and 2023. It features a DOHC 12‑valve layout, common‑rail direct injection, and a fixed‑geometry turbocharger. In standard form it delivered 70 kW (95 PS) at 3,750 rpm and 230 Nm of torque at 1,500 rpm, providing efficient urban performance with strong low‑end responsiveness.
Fitted to models such as the Corsa F and Crossland X, the B13DTE was engineered for compact city driving with fuel‑efficient cruising capability. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), and a selective catalytic reduction (SCR) system with AdBlue injection, enabling Euro 6d‑TEMP compliance across its production run.
One documented concern is premature AdBlue injector coking and dosing faults, highlighted in Vauxhall Service Bulletin 19‑042. This issue stems from frequent short‑trip operation preventing full thermal cycles required to clear urea deposits. From late 2020, revised injector seals and updated dosing strategies were introduced to improve reliability.
All production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/9254).
The Vauxhall B13DTE is a 1,248 cc inline‑three turbo‑diesel engineered for subcompact and compact crossover models (2018–2023). It combines Bosch CP4.2 common‑rail injection with a fixed‑geometry turbocharger to deliver responsive low‑rpm torque and urban fuel efficiency. Designed to meet Euro 6d-TEMP emissions standards, it integrates AdBlue SCR technology for NOx control.

The B13DTE offers brisk low-end torque ideal for city driving but requires regular highway use to maintain AdBlue and DPF system health. Frequent short trips prevent thermal regeneration cycles, leading to AdBlue injector coking and SCR dosing faults. Use of EN 590 ultra-low sulfur diesel and Dexos2 0W-30 oil is mandatory. AdBlue consumption averages 1.2 L per 1,000 km; low-fluid warnings must not be ignored. Revised injector seals introduced in late 2020 improve reliability—pre-2021 engines should be inspected per Vauxhall SIB 19‑042.
Oil Specs: Requires GM Dexos2 0W-30 (ACEA C2/C5) specification (Vauxhall Owner’s Manual 2019). Non-Dexos oils risk aftertreatment damage.
Emissions: Euro 6d-TEMP certification applies to all B13DTE production (2018–2023) (VCA Type Approval #VCA/EMS/9254).
Power Ratings: Measured under UN ECE R85 standards. Power output verified via VCA chassis dyno certification (VCA/EMS/9254).

The Vauxhall B13DTE was used across Vauxhall's Corsa F and Crossland X platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Crossland X and modified exhaust manifolds in the Corsa F—and from late 2020 the Corsa F LCI adopted updated AdBlue injector seals and dosing calibrations, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the timing cover (Vauxhall TIS B13DTE‑01). The 8th VIN digit indicates engine displacement ('3' for 1.3L). All B13DTE units feature black cam covers with '1.3 CDTi' embossed and a single fixed-geometry turbo on the exhaust side. Critical differentiation from B15DTH: B13DTE is a 3-cylinder with AdBlue; B15DTH is a 4-cylinder petrol without SCR. Post-2020 engines have revised AdBlue injector part numbers; pre-2021 injectors are not backward-compatible (Vauxhall SIB 19‑042).
The B13DTE's primary reliability risk is AdBlue injector coking and dosing system faults, with elevated incidence in predominantly urban or short-trip use. Vauxhall internal data (2021) noted SCR-related warning lights in ~9% of pre-2021 engines beyond 60,000 km, while UK DVSA MOT records show increased NOx-related emissions failures in low-mileage city vehicles. Cold starts and infrequent highway driving prevent thermal cleaning cycles, making driving pattern and AdBlue maintenance critical.
