The Nissan YD22DDTi is a 2,184 cc, inline‑four turbo‑diesel engine produced between 2001 and 2007. It features a cast — iron block, aluminium cylinder head, and a variable geometry turbocharger (VGT) paired with common rail direct injection. In standard form for the Almera and Primera, it delivered 88 kW (120 PS) and 275 Nm of torque, providing strong low — end pull for everyday drivability.
Fitted to models like the N16 Almera, P12 Primera, and T30 X — Trail, the YD22DDTi was…
Production years 2001–2007 meet Euro 3 standards (VCA UK Type Approval not applicable for this non-EU homologated variant in some markets).
The Nissan YD22DDTi is a 2,184 cc inline‑four turbo‑diesel engineered for compact and SUV models (2001-2007). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 3 standards, it balances everyday performance with economy.

The Nissan YD22DDTi was used across Nissan's N16/P12 platforms with transverse mounting and no licensed partners. This engine received platform-specific adaptations-different engine mounts for the X-Trail and revised intake manifolds for the Primera-creating minor 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.
The YD22DDTi's primary reliability risk is variable geometry turbocharger actuator failure, with elevated incidence in vehicles with high idle times or short trips. Nissan Service Bulletin NTB03-098 documents the issue, while owner reports frequently cite EGR system clogging as a secondary cause of running problems. Adherence to preventative maintenance for the turbo and EGR system make longevity critical.
Analysis derived from Nissan technical bulletins (2001-2007) and owner-reported failure data (2008-2023). 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 YD22DDTi is generally robust with proper maintenance. Its main weaknesses are the VGT actuator and EGR system, which require attention. With regular oil changes, clean fuel, and preventative cleaning of the EGR and turbo actuator, a YD22DDTi can be very reliable and last well beyond 250,000 km.
The most frequent issues are VGT actuator linkage binding, EGR valve and cooler clogging, high-pressure fuel pump failure, and oil leaks from the rocker cover. These are well-documented in Nissan service bulletins and are common knowledge among specialist mechanics.
The YD22DDTi was used in the Nissan Almera (N16, 2001-2006), Primera (P12, 2002-2007), and X-Trail (T30, 2003-2007). It was not used in any other Nissan production vehicles or licensed to other manufacturers.
Yes, the YD22DDTi responds well to ECU remapping. Stage 1 tunes can safely increase power to around 100-110 kW (135-150 PS) and torque to 320-350 Nm. The stock turbo and internals are generally capable of handling this. More aggressive tuning requires supporting modifications like a larger intercooler.
Fuel economy is excellent for its era. Expect around 6.5-7.5 L/100km (38-43 mpg UK) in combined driving for a hatchback like the Almera. The heavier X-Trail 4x4 will be closer to 8.0-9.0 L/100km (31-35 mpg UK). Real-world figures depend heavily on driving style and maintenance.
Yes. The YD22DDTi is an interference engine. If the timing chain fails or jumps, the pistons will contact the valves, causing severe internal engine damage. Fortunately, the chain system is very durable and rarely fails if oil is changed regularly.
Nissan specifies an oil meeting ACEA B4 standard. SAE 5W-30 is recommended for year-round use in most climates, while 10W-40 can be used in consistently warmer conditions. Always use a high-quality synthetic or semi-synthetic oil designed for turbocharged diesel engines.
