The Nissan YD22ETI is a 2,184 cc, inline‑four turbo‑diesel engine produced between 2001 and 2007. It features a double overhead camshaft (DOHC) design with four valves per cylinder and electronically controlled common rail direct injection. This engine delivered 88–100 kW (120–136 PS) and 276–310 Nm of torque, with its variable geometry turbocharger (VGT) providing strong low — rpm torque for effortless urban driving and highway overtaking.

Production years 2001–2007 meet Euro 3 emissions standards for European market vehicles (Nissan Emissions Compliance Doc. YD-EU3-01).
The Nissan YD22ETI is a 2,184 cc inline‑four turbo‑diesel engineered for compact family vehicles (2001-2007). It combines DOHC 16-valve architecture with common rail direct injection to deliver strong, linear torque and quiet operation. Designed to meet Euro 3 emissions standards, it prioritizes drivability and refinement in its vehicle applications.

The Nissan YD22ETI was used across Nissan's N16/P12 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Primera for enhanced NVH control-and from 2004 minor ECU revisions for improved diagnostics, creating minor interchange limits for control units. 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.
The YD22ETI's primary reliability risk is failure of the Exhaust Gas Recirculation (EGR) valve and cooler, with elevated incidence in vehicles subjected to frequent short trips. Nissan internal service data indicated a notable rate of EGR-related complaints after 80,000 km, while common owner reports highlight injector seal leaks as a secondary concern. Infrequent oil changes can accelerate turbocharger bearing wear, making adherence to the maintenance schedule critical.
Analysis derived from Nissan technical bulletins (2001-2007) and aggregated owner-reported failure data (2007-2023). 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 YD22ETI is generally a robust engine with strong torque. Its main long-term concerns are the EGR system and injector seals, which are relatively inexpensive to fix. With regular oil changes every 15,000 km and timely cleaning of the EGR system, a YD22ETI can easily exceed 250,000 km. Its chain-driven timing system is a significant durability advantage over belt-driven designs.
The most frequent issues are clogging and failure of the EGR valve and cooler, leaks from the fuel injector seals, and oil leaks from the timing cover gasket. Less common but serious is turbocharger bearing wear, often linked to poor maintenance. These are well-documented in Nissan service bulletins.
The YD22ETI was primarily used in the Nissan Almera (N16 generation, 2001-2006), Nissan Primera (P12 generation, 2002-2007), and Nissan Almera Tino (V10 generation, 2001-2006). It was marketed as the 2.2 dCi and was positioned as the performance diesel option in these compact and mid-size models.
Yes, the YD22ETI responds well to tuning. A simple ECU remap can yield gains of 20-30 kW and 50-70 Nm safely, as the engine has strong internals. More aggressive tuning requires upgrades to the turbocharger, intercooler, and clutch. It's a popular candidate for tuning due to its robust design and good factory torque output.
Fuel economy is very good for its era and performance. Expect around 6.5–7.5 L/100km (43–38 mpg UK) in combined driving for an Almera or Primera. Highway cruising can see figures as low as 5.5 L/100km (51 mpg UK). Actual consumption is highly dependent on driving style and the condition of the EGR system.
Yes. The YD22ETI is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain system is very durable with proper maintenance.
Nissan recommends API CF-4 or CG-4 grade 5W-30 or 10W-40 engine oil. Using a high-quality synthetic or semi-synthetic oil of the correct viscosity is crucial for protecting the turbocharger bearings and timing chain tensioners, especially in varying climates.
