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, and Zafira Life, the M9T 702 was engineered for durability, payload capacity, and fleet reliability. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), allowing adherence to Euro 5 standards in early builds and Euro 6b in later production.
One documented concern is premature failure of the high-pressure fuel pump (HPFP), noted in Vauxhall Service Bulletin PI1025. This is attributed to thermal stress and marginal lubricity in early-design Bosch CP4.2 internals under sustained high-load conditions. From 2016, revised HPFP components and updated engine control software were introduced to improve reliability.
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 VGT turbo provides strong low-end torque ideal for payload and towing but requires consistent use of EN 590 diesel and DEXOS2 oil to protect the high-pressure fuel system and turbo bearings. Extended oil change intervals beyond 20,000 km or 12 months may accelerate wear in the Bosch CP4.2 pump and timing chain. The DPF requires periodic highway driving (>60 km/h for 15+ minutes) to enable passive regeneration. Vauxhall SIB PI1025 recommends replacing the HPFP with updated part number (13625780) for pre-2016 engines exhibiting rail pressure faults.
Oil Specs: Requires DEXOS2 5W-30 (ACEA C3) specification (Vauxhall Owner's Manual Vivaro B 2014). Not interchangeable with DEXOS1.
Emissions: Euro 5 applies to 2012–2015 models; Euro 6b certification confirmed for 2016–2021 builds (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under EU Regulation (EC) No 715/2007. Output assumes EN 590 diesel and ambient conditions per ISO 1585.

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.
Locate the engine code stamped on the front timing cover near the oil pump (Vauxhall TIS TIS-M9T-01). The 7th and 8th VIN digits identify engine variant ('M9' for M9T series). All units use Bosch EDC17C74 ECU with black casing. Critical differentiation from M9T 720: M9T 702 has 140 PS output and lower boost calibration. Service parts for fuel system require production date verification—HPFPs before 01/2016 use part number 13610450; later units use 13625780 with revised internals (Vauxhall SIB PI1025).
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.
