FORD Diesel Particulate Filter DPF Focus 2 (II) (2004-2011) 1.6 TDCi Diesel

A diesel particulate filter (DPF) is a critical exhaust component in your Ford Focus diesel. It traps fine particles from unburned fuel and burns them off using heat, keeping your car clean and compliant with Ford Motor Company emissions standards.

Your DPF type depends on your Focus model, engine code, and emissions class (Euro 4, 5, or 6). For example, the Ford Focus MK2 often uses an additive-based system that includes a fluid reservoir, sensor, and pipe to inject Eolys.

Key benefits of a working DPF:

• Prevents harmful particle release
• Supports better fuel economy
• Extends turbo and converter lifespan
• Ensures roadworthy condition

If your filter is restricted or nearing the end of its recommended interval, your car will often show signs of accumulation:

• Warning light on the dash
• Reduced throttle response
• Increased fuel usage
• Black smoke from the exhaust
• Idle stalling or cold start hesitation
• Error messages or fault codes like P242F

These are classic DPF issues caused by soot buildup, which blocks the filter over time—especially in city driving.

Yes—depending on its condition, a cleaned filter can work just as well as a new one. Here’s how:

• Passive regeneration
  Longer drives at stable speed (like on a motorway) help raise exhaust temps to burn off excess soot.
• Manual regeneration
  A garage or DIYer with the right tool can manually trigger a regen via the OBD port.
• Additive cleaner
  Pour-in cleaners or sprays can break down carbon inside the filter through the sensor or pipe entry points.

If the filter is saturated or damaged, a replacement is the safest long-term solution.

You should change your diesel particulate filter every 120,000 km or sooner if the system cannot regenerate properly. For many, this means around 75,000 miles.

Krosfou’s recommendation: Replace your filter every 100,000–120,000 km, especially if you do mostly short trips.

Older models like the Ford Focus MK2 or 2012 Ford Focus with Duratorq TDCi engines may also require an Eolys top-up, which helps with regeneration.

Absolutely. Many customers handle the installation at home—especially when ordering a fitting kit. It includes essentials like clamps, gaskets, and mounting hardware.

For a successful DIY install, you’ll need:

• A compatible filter for Ford Focus
• Basic tools and a jack
• Reset capability via OBD
• A stable surface and clear instructions

Look for these signs:

• No DPF or fault light
• Steady fuel economy
• No smoke or smells
• Good engine response
• Acceptable sensor readings on scan tool

If you’re unsure, we recommend a DPF health check or professional cleaning. Or simply buy a new one and return your core item.

We don’t recommend it.

That light is a sign that the system’s pressure is too high—often due to restriction from soot. If ignored, it can lead to engine damage, failed emissions tests, and costly repairs.

Try regeneration or cleaning, but if you’re seeing repeat errors, opt for a replacement.

Our filters are engineered to meet a range of needs:

• Cordierite: budget-friendly, great for town drivers
• Silicon carbide: durable, higher heat resistance
• Catalytic particulate filters: include a converter for improved emissions

Every item we sell is certified to Euro 4/5/6 and manufactured for exact fit.

Yes. Our accessories include:

• DPF pipes, clamps, and couplings
