The Vauxhall M9R 780 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2006 and 2018 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 96 kW (130 PS) and 320 Nm of torque, offering strong low‑end response for mid‑size crossovers and light commercial vehicles.
Fitted to models such as the Vauxhall Antara, Vivar…
Production years 2006–2009 meet Euro 4 standards; 2010–2018 models comply with Euro 5 .
The Vauxhall M9R 780 is a 1,995 cc inline‑four turbo‑diesel engineered under Renault licence for mid-size passenger and light commercial vehicles (2006–2018). It combines common-rail direct injection with a variable-geometry turbocharger to deliver robust low-rpm torque and towing capability. Designed to meet Euro 4 and Euro 5 emissions standards, it balances utility with regulatory compliance.

The Vauxhall M9R 780 was used across Vauxhall's Antara, Vivaro A, and Zafira Tourer C platforms with transverse mounting under licence from Renault. This engine received platform-specific adaptations—reinforced engine mounts in the Vivaro for commercial load tolerance and modified exhaust routing in the Antara—and from 2010 minor timing system updates were introduced to address tensioner durability, creating service part 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 M9R 780 is generally robust when maintained properly, but early models (2006–2009) had timing tensioner durability concerns. Post-2010 revisions improved chain system longevity. Using DEXOS2 5W-30 oil, EN 590 diesel, and adhering to service intervals greatly enhances reliability.
Top issues include timing chain tensioner wear, DPF saturation from short trips, EGR valve coking, and turbo actuator sticking. These are documented in Vauxhall service bulletins like PI0512 and supported by DVSA MOT data.
The M9R 780 powers the Antara (2006–2015), Vivaro A (2006–2018), and Zafira Tourer C (2005–2011) in 130 PS form. It is a Renault-sourced 2.0L diesel used under licence, identifiable by DOHC architecture, single VGT turbo, and Euro 4/Euro 5 compliance with DPF.
Aftermarket ECU tuning is common on the M9R-780 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.
In a Vivaro 2.0 CDTI 130 PS, expect ~6.4 L/100km (city), ~5.3 L/100km (highway), or ~41 mpg UK combined. Real-world mixed driving typically returns 37–44 mpg UK. Fuel economy is competitive for a Euro 4/5 diesel with DPF complexity.
Yes. The M9R 780 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 timing system. Never use DEXOS1 or non-approved oils. Change every 20,000 km or 12 months.
