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 (VCA UK Type Approval #VCA/EMS/5678).
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.
The NWN's primary reliability risk is variable cam timing (VCT) solenoid malfunction, with elevated incidence in high-mileage or poorly maintained engines. Ford internal data from 2009 indicated a notable share of pre-2008 builds required solenoid replacement before 100,000 km, while UK DVSA records show minimal emissions-related failures due to robust catalyst design. Infrequent oil changes and use of non-spec oil increase solenoid clogging risk, making correct oil specification and interval adherence critical.
Analysis derived from Ford technical bulletins (2007–2012) and UK DVSA failure statistics (2015–2023). 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 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.
