The Vauxhall M9T 716 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2014 and 2021 under licence from Renault. It features dual overhead camshafts (DOHC), 16 valves, and a variable geometry turbocharger (VGT) with intercooler. In standard form it delivered 103 kW (140 PS) at 3,750 rpm and 340 Nm of torque at 1,750 rpm, providing strong low-end pull for mid-size vans and crossovers.
Fitted to models such as the Vivaro B and Grandland X, the M9T 716 was engineered for durability, towing capability, and refined operation in commercial and family applications. Emissions compliance was achieved through high-pressure common-rail injection, exhaust gas recirculation (EGR), and a diesel oxidation catalyst, allowing all units to meet Euro 6b standards.
One documented concern is premature failure of the diesel particulate filter (DPF) regeneration cycle due to urban driving patterns, which can lead to excessive soot accumulation and limp-mode activation. This issue, highlighted in Vauxhall Service Bulletin TIS-16-09-20, is attributed to insufficient exhaust temperatures during short trips preventing passive regeneration. From 2017, updated ECU calibration improved regeneration logic and reduced DPF-related complaints.
All production years 2014–2021 meet Euro 6b standards (VCA UK Type Approval #VCA/EMS/8452).
The Vauxhall M9T 716 is a 2,298 cc inline‑four turbo‑diesel engine engineered for light commercial and compact SUV applications (2014–2021). It combines DOHC 16-valve architecture with a variable geometry turbocharger to deliver robust low-RPM torque and highway refinement. Designed to meet Euro 6b emissions standards, it balances load-carrying capability with fuel efficiency.

The DOHC VGT design provides strong, linear torque ideal for towing and mixed-use driving but requires strict adherence to 15,000 km or 12-month oil change intervals using low-SAPS ACEA C3 oil to protect the DPF and turbo actuator. The Bosch CP4.2 high-pressure pump is sensitive to fuel lubricity; only EN 590-compliant ultra-low-sulfur diesel should be used. DPF regeneration issues are common in urban driving—vehicles should complete at least one 30-minute highway run monthly to enable passive regeneration. Post-2017 ECU updates improved regeneration logic per Vauxhall SIB TIS-16-09-20.
Oil Specs: Requires ACEA C3 (5W-30) low-SAPS oil specification (Vauxhall SIB TIS-16-09-20) to ensure DPF compatibility.
Emissions: Euro 6b certification applies to all model years (VCA Type Approval #VCA/EMS/8452). No earlier emissions variants exist.
Power Ratings: Measured under SAE J1349 standards. Output consistent across all applications (Vauxhall TIS Doc. V14‑3601).

The Vauxhall M9T 716 was used across Vauxhall's Vivaro B and Grandland X platforms with longitudinal mounting and licensed from Renault. This engine received platform-specific adaptations—reinforced engine mounts in the Vivaro B for payload stability and revised cooling ducts in the Grandland X—and from 2017 the ECU calibration was updated to improve DPF regeneration, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left side of the cylinder block near the turbocharger (Vauxhall TIS V14‑3601). The 8th VIN digit indicates engine displacement ('T' for 2.3L diesel). All M9T 716 units feature a black plastic cam cover with '2.3 dCi' embossed and dual camshaft pulleys. Critical differentiation from M9T 724: M9T 716 uses Bosch EDC17C74 ECU with 24-pin under-hood connector; M9T 724 is a higher-output variant (170 PS) with twin-turbo configuration. Service parts for DPF and ECU differ pre/post 2017 due to regeneration logic changes (Vauxhall SIB TIS-16-09-20).
The M9T 716's primary reliability risk is DPF regeneration failure due to urban driving patterns, with elevated incidence in stop-start city use. Vauxhall internal data from 2019 noted increased limp-mode activations on Vivaro B vans under 60,000 km in delivery fleets, while UK DVSA MOT records show DPF-related emissions failures as a recurring cause in light commercial vehicles. Frequent short trips and delayed oil changes accelerate soot accumulation, making scheduled highway driving critical.
