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 (VCA UK Type Approval #VCA/EMS/9218).
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.
The B16DTH's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the camshaft in early builds, with elevated incidence in urban short-trip usage. Vauxhall internal quality data from 2021 indicated a measurable rate of camshaft/HPFP replacements before 70,000 km in pre-2020 units, while UK DVSA MOT records show DPF-related failures increasing after 90,000 km in vehicles with incomplete regeneration cycles. Cold starts and low-load operation accelerate wear, making oil quality and driving pattern critical.
Analysis derived from Vauxhall technical bulletins (2018–2023) and UK DVSA failure statistics (2020–2023). Repair procedures should follow manufacturer guidelines.
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.
Yes. Stage 1 ECU remaps typically yield +10–20 kW safely, as the turbo and internals handle moderate increases. However, aggressive tuning without HPFP and clutch upgrades risks premature cam lobe or pump failure, especially on pre-2020 engines.
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.
