The Vauxhall M9T 702 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2012 and 2021 under licence from Renault. It features a single variable geometry turbocharger (VGT), common‑rail direct injection, and dual overhead camshafts (DOHC) with 16 valves. In standard form it delivers 103 kW (140 PS) and 340 Nm of torque, offering strong low‑end response for light commercial vehicles and mid‑size MPVs.
Fitted to models such as the Vauxhall Vivaro B, Movano B, a…
Production years 2012–2015 meet Euro 5 standards; 2016–2021 models comply with Euro 6b (VCA UK Type Approval #VCA/EMS/6789).
The Vauxhall M9T 702 is a 2,298 cc inline‑four turbo‑diesel engineered under Renault licence for light commercial and passenger MPVs (2012–2021). It combines common-rail direct injection with a variable-geometry turbocharger to deliver robust low-rpm torque and fleet-grade durability. Designed to meet Euro 5 and Euro 6b emissions standards, it balances utility with regulatory compliance.

The Vauxhall M9T 702 was used across Vauxhall's Vivaro B, Movano B, and Zafira Life platforms with transverse mounting under licence from Renault. This engine received platform-specific adaptations—reinforced engine mounts in the Movano for heavy-duty use and modified exhaust routing in the Zafira Life—and from 2016 minor fuel system updates were introduced to address HPFP durability, creating service part interchange limits. All adaptations are documented in OEM technical bulletins.
The M9T 702's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in sustained high-load or hot-climate use. Vauxhall internal data from 2018 indicated a measurable uptick in HPFP replacements before 120,000 km for 2012–2015 units, while UK DVSA records show DPF-related warning lights as the second-most common emissions fault in urban-driven examples. Extended oil intervals and low-quality fuel amplify HPFP and turbo stress, making adherence to DEXOS2 oil and EN 590 diesel critical.
Analysis derived from Vauxhall technical bulletins (2014–2021) and UK DVSA failure statistics (2018–2024). 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 M9T 702 is generally robust when maintained properly, but early models (2012–2015) had HPFP reliability concerns. Post-2016 revisions improved fuel system durability. Using DEXOS2 5W-30 oil, EN 590 diesel, and adhering to service intervals greatly enhances longevity.
Top issues include high-pressure fuel pump wear, DPF saturation from short trips, EGR valve coking, and turbo actuator sticking. These are documented in Vauxhall service bulletins like PI1025 and supported by DVSA MOT data.
The M9T 702 powers the Vivaro B (2014–2021), Movano B (2012–2021), and Zafira Life (2019–2021) in 140 PS form. It is a Renault-sourced 2.3L/2.0L diesel used under licence, identifiable by DOHC architecture, single VGT turbo, and Euro 5/Euro 6b compliance with DPF.
Modest gains are possible. ECU remaps typically yield +15–20 kW (160–165 PS) safely on stock hardware. The turbo and internals tolerate mild increases, but fuel quality and cooling become critical above 165 PS. Always pair tuning with DEXOS2 oil and quality EN 590 diesel.
In a Vivaro 2.3 CDTI 140 PS, expect ~6.8 L/100km (city), ~5.6 L/100km (highway), or ~38 mpg UK combined. Real-world mixed driving typically returns 35–42 mpg UK. Fuel economy is competitive for a Euro 5/6 diesel with DPF complexity.
Yes. The M9T 702 is an interference design. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service under proper maintenance.
Vauxhall specifies DEXOS2 5W-30 (ACEA C3) synthetic oil. This low-SAPS formulation protects the DPF and turbo. Never use DEXOS1 or non-approved oils. Change every 20,000 km or 12 months.
