The Ford NWN is a 1,999 cc, inline‑four naturally aspirated petrol engine produced between 2007 and 2011. It features dual overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. In standard form it delivered 107 kW (145 PS) at 6,000 rpm and 190 Nm of torque at 4,500 rpm, providing responsive everyday drivability.
Fitted to models such as the C‑MAX, Focus, and S‑MAX, the NWN was engineered for balanced performance and fuel economy in compact and mi…
All production years (2007–2011) meet Euro 4 emissions standards .
The Ford NWN is a 1,999 cc inline‑four naturally aspirated petrol engine engineered for compact and midsize models (2007–2011). It combines DOHC architecture with sequential multi‑point fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 4 emissions standards, it balances everyday usability with moderate fuel consumption.

The Ford NWN was used across Ford's C1 platform with transverse mounting. This engine received platform-specific adaptations—revised engine mounts in the S‑MAX and modified accessory drive routing in the Focus—creating minor service part differences. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 NWN is generally reliable with proper maintenance. Early models (2007–2008) had VCT solenoid issues, resolved in later builds. Using correct 5W-30 oil (WSS-M2C913-C) and regular servicing ensures longevity. Most well-maintained examples exceed 200,000 km without major issues.
Top issues include VCT solenoid sticking (causing timing codes), IMRC actuator faults, timing chain tensioner wear, and thermostat housing leaks. These are documented in Ford service bulletins like 07S034 and are manageable with OEM parts and proper diagnostics.
The NWN 2.0L petrol was used in the Focus Mk2 (2007–2011), C-MAX Mk1 facelift (2007–2010), and S-MAX (2007–2010). All are transverse-mounted applications on Ford’s C1 platform, meeting Euro 4 emissions standards.
Modest gains are possible via ECU remapping (+10–15 kW), but the naturally aspirated design limits potential. Forced induction is not recommended without major internal upgrades. Most owners focus on drivability improvements rather than significant power increases.
Real-world consumption is ~8.5 L/100km (city) and ~5.8 L/100km (highway), or about 33 mpg UK combined. Expect 30–36 mpg (UK) depending on driving style and vehicle model (Focus vs S-MAX).
No. The Ford NWN is a non-interference engine. If the timing chain fails, pistons will not contact valves, preventing catastrophic internal damage—though repair is still required to restore function.
Ford specifies SAE 5W-30 oil meeting WSS-M2C913-C standard. This ensures proper VCT solenoid operation and chain lubrication. Change every 15,000 km or 12 months, whichever comes first.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
