Ford S-Max Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on the Ford S-Max, mainly for diesel engines like the 2.0 TDCi and 2.2 TDCi, is an exhaust system component that captures and removes fine soot particles from the exhaust gases. It complies with Euro 4 or Euro 5 emission standards and works by filtering soot followed by thermal regeneration to burn off the particles.

DPFs are fitted on Ford S-Max diesel engines including:

• 2.0 TDCi 140 HP (engine codes: QXWA, QXWC, UFWA)
• 2.2 TDCi (engine code: KNWA)

Production years range approximately from 2010 to 2015, with different temperature sensor configurations and materials such as cordierite used for the filter element.

Common symptoms indicating DPF issues include:

• Increased fuel consumption
• Loss of engine power
• "Check Engine" warning light illumination
• OBD fault codes such as P244C, P2463, and P243F

Specific issues for S-Max/Galaxy WA6 models can also arise from failed injectors or glow plugs affecting regeneration, as well as rust or counterfeit parts accelerating wear after around 200,000 km.

The DPF filters soot particles and then performs a thermal regeneration by burning off accumulated soot at high temperatures. This is achieved by injecting fuel post-catalytic converter to heat the exhaust, unlike AdBlue systems.

• Driving at 65-80 km/h for about 24-26 minutes can naturally raise temperature to clean ashes.
• A diagnostic tool such as VCDS can be used to initiate forced regeneration if necessary.

Proper drying after cleaning and avoiding counterfeit parts help maintain DPF performance and safety.

Recommended replacement intervals range from approximately 125,000 to 195,000 km for the 2.0 TDCi engine, but earlier replacement may be necessary if reliability is poor or filter is heavily clogged.

• Typical aftermarket DPF prices vary, with OEM parts costing around €500.
• Professional installation using proper sensor handling is recommended.
• Alternative options like stainless steel DPF removal tubes exist but must be checked for legal and emission compliance.

Step-by-step guides and video tutorials are available to assist with replacement procedures.

Yes, driving mostly in urban stop-and-go traffic can cause quicker DPF clogging and failures. Regular motorway driving helps maintain higher exhaust temperatures for natural regeneration.

• Avoiding short trips and ensuring complete regeneration cycles helps prolong filter life.
• Regular diagnostics to check sensor functionality and fault codes are useful preventive measures.
• Use only high-quality, non-counterfeit parts to avoid premature rust and damage.

Following recommended maintenance and usage guidelines optimises the DPF's durability and your vehicle's emission compliance.

Diagnosing a blocked DPF requires:

• Reading trouble codes such as P244C, P2463, P243F via an OBD diagnostic tool
• Monitoring temperature sensors and pressure differentials across the DPF
• Inspecting related systems like injectors and glow plugs that affect regeneration

Consulting with qualified mechanics or using advanced diagnostic tools can differentiate between genuine blockages and other exhaust system or engine issues affecting DPF performance and vehicle emissions.
