The Nissan M1D is a 1,461 cc, inline‑three turbo‑diesel engine produced from 2018 to present. It features an aluminium block and head, dual overhead camshafts (DOHC), and 12 valves with common rail direct injection. This compact engine was designed for efficiency and low-end torque in Nissan's global supermini platforms.
Fitted exclusively to the Nissan Micra (K14) in European markets, the M1D was engineered for urban efficiency and responsive acceleration from low RPMs. Emissions compliance is achieved through its common rail injection, exhaust gas recirculation (EGR), and a diesel particulate filter (DPF), meeting stringent Euro 6d standards.
One documented service consideration is the sensitivity of the high-pressure fuel system to fuel quality, as noted in Nissan Technical Bulletin NTB18-055. Contaminated or low-quality diesel can lead to injector or pump issues. The engine is a result of Nissan's partnership with Renault, sharing core architecture with the Renault H5Dt engine.
Production years 2018–Present meet Euro 6d emissions standards for all applicable markets (Nissan Technical Service Bulletins, EU Regulation (EC) No 715/2007 as amended).
The Nissan M1D is a 1,461 cc inline‑three turbo‑diesel engineered for supermini applications (2018-Present). It combines common rail direct injection with a DOHC 12-valve valvetrain and a small turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet stringent Euro 6d emissions standards, it prioritizes urban drivability with low emissions.

The three-cylinder design offers excellent fuel economy and strong low-RPM torque for city driving but requires strict adherence to 20,000 km oil change intervals to protect the turbo and DPF. ACEA C2/C3 5W-30 oil is critical for DPF longevity. The common rail system is sensitive to fuel quality; contaminated diesel can damage injectors or the high-pressure pump. The timing chain is designed for life but should be inspected if a rattle develops. EGR and DPF systems require periodic highway driving for effective regeneration.
Oil Specs: Requires ACEA C2/C3 specification 5W-30 oil (Nissan Owner's Manual). Low-SAPS formulation is essential for DPF protection.
Emissions: Euro 6d certification applies to all production years (EU Regulation (EC) No 715/2007 as amended).
Power Ratings: Measured under JIS D 1001 standards. Output is consistent across all Micra applications (Nissan Global Product Data).

The Nissan M1D was used exclusively in Nissan's K14 platform with transverse mounting. This engine is a product of the Renault-Nissan Alliance, sharing its core design with the Renault H5Dt. No platform-specific adaptations exist beyond ECU tuning. All specifications are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the alternator (Nissan SM-M1D). The 8th VIN digit often corresponds to engine type ('D' for diesel variants in many markets). Visually, it features twin cam covers (DOHC) and a prominent turbocharger with an intercooler pipe. Critical differentiation from petrol engines: The M1D is the only diesel engine offered in the K14 Micra. Service parts for the fuel injection and emissions systems are specific to this diesel variant.
The M1D's primary reliability consideration is the sensitivity of its high-pressure fuel system to fuel quality, as documented in Nissan service data. NTB18-055 indicates that contaminated fuel is a leading cause of injector or pump failure. DPF clogging can occur with predominantly short-trip driving, while EGR valve sticking is a known service item on high-mileage examples. Adherence to OEM maintenance schedules is critical.
