The Vauxhall B16DTH (DV6FC) is a 1,499 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 96 kW (130 PS) with 300 Nm of torque, engineered for responsive urban driving and low CO₂ emissions.
Fitted to models such as the Astra K, Crossland, and Grandland, including the 1.5 Turbo D 130 variants, the B16DTH was d…
Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d depending on market .
The Vauxhall B16DTH (DV6FC) is a 1,499 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2018–2023). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and class-leading urban efficiency. Designed to meet Euro 6d TEMP and Euro 6d emissions standards, it balances performance with regulatory compliance.

The Vauxhall B16DTH (DV6FC) was used across Vauxhall's Astra K, Crossland, and Grandland platforms with transverse mounting and no external licensing. This engine, originally developed by PSA as the DV6FC, was integrated into Vauxhall’s lineup post-GM divestment and received platform-specific calibrations—revised idle logic in the Astra and enhanced NVH tuning in the Grandland—and from 2020 the Euro 6d-compliant variants featured updated camshaft profiles and DPF control strategies, 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 B16DTH offers strong low-end torque and good efficiency, but early models (2018–2020) had HPFP drive lobe wear concerns. Post-2020 revisions with updated camshaft profiles improved durability. With proper maintenance—especially using GM Dexos2 0W‑30 oil and avoiding constant short trips—these engines can reliably exceed 160,000 km.
Top issues include HPFP cam lobe wear (early builds), DPF regeneration faults from urban driving, EGR valve sticking, and turbo actuator binding. These are documented in Vauxhall service bulletins PI1215 and TIS updates.
The B16DTH powered the Astra K (2018–2023), Crossland (2018–2023), and Grandland (2018–2023) in 1.5 Turbo D 130 variants. It is the Vauxhall-badged version of PSA’s DV6FC diesel engine, used across Stellantis platforms.
Aftermarket ECU tuning is common on the B-16-DTH-DV6FC 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.
Excellent for its class. In an Astra 1.5 Turbo D 130, expect ~4.2 L/100km (67 mpg UK) combined. Real-world mixed driving typically returns 55–62 mpg UK (4.5–5.1 L/100km), depending on driving style and conditions.
Yes. The B16DTH 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 Dexos2-approved 0W‑30 synthetic oil is mandatory. This low-SAPS formulation protects the DPF, turbo, and HPFP drive system. Change intervals should not exceed 15,000 km or 12 months, especially with urban use.
