The Vauxhall B12XHT (also known as PSA EB2DTS) is a 1,199 cc, inline‑three turbo‑charged diesel engine produced between 2018 and 2023. It features a DOHC 12‑valve layout with high — pressure common‑rail direct injection and a fixed‑geometry turbocharger. In standard form it delivered 70 kW (95 PS) and 230 Nm of torque, optimized for urban efficiency and compact vehicle packaging.

The Vauxhall B12XHT (EB2DTS) is a 1,199 cc inline‑three turbo‑diesel engineered for subcompact and compact SUVs (2018–2023). It combines Bosch common‑rail injection with a fixed-geometry turbocharger to deliver responsive low‑rpm torque in a compact footprint. Designed to meet Euro 6d emissions standards, it integrates AdBlue® SCR technology alongside EGR and DPF systems for regulatory compliance.

The Vauxhall B12XHT (EB2DTS) was used across Vauxhall's Crossland X and Grandland X platforms with transverse mounting and developed jointly with PSA Group. This engine received platform-specific adaptations—revised AdBlue tank routing in the Grandland and modified engine mounts in the Crossland—and from 2021 the facelifted Grandland models adopted updated ECU calibrations, 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 B12XHT offers compact packaging and Euro 6d compliance, but early models (2018–2020) had HPFP cam lobe reliability concerns. Later units improved camshaft hardness, so well-maintained examples can be robust. Regular servicing and using GM Dexos2 5W‑30 oil greatly aid longevity.
The biggest issues are HPFP cam lobe wear, AdBlue crystallization from short trips, DPF pressure sensor drift, and EGR valve sticking. These are documented in Vauxhall service bulletins TIS 19‑063 and 18‑055.
This 1.2L diesel was used in the Crossland X (2018–2023) and Grandland X (2018–2023) as the 1.2 Diesel 95 PS variant with AdBlue/SCR. It is a PSA-sourced EB2DTS unit and was not used in non-SUV Vauxhall lines.
Aftermarket ECU tuning is common on the B-12-XHT-EB2DTS 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 Crossland X 1.2 Diesel, typical consumption is ~5.2 L/100km (city) and ~3.8 L/100km (highway), or about 60 mpg UK combined. Real-world economy varies with driving style—expect 52–62 mpg UK on mixed roads for a healthy, unmodified engine.
Yes. The B12XHT is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic damage. While the chain is generally durable, any unusual timing noise should be investigated immediately.
Vauxhall specifies GM Dexos2 5W‑30 synthetic oil. This is critical for HPFP cam lobe lubrication and turbo protection. Always change oil every 15,000 km or 12 months, whichever comes first, especially in stop-start or urban use.
