Description

This product listing covers a reconditioned Diesel Particulate Filter (DPF) for the Ford Focus 1.6 TDCi, specifically designed for Euro 4 emission standards. We offer a professional cleaning service for your existing DPF unit, restoring its function and avoiding costly replacement while ensuring compliance with UK regulations.

A Diesel Particulate Filter (DPF) is an essential emissions control device fitted to diesel vehicles, designed to capture harmful particulate matter (soot) from the exhaust gas before it enters the atmosphere. The collected soot is periodically burned off during a process called regeneration. Over time, DPFs accumulate not only soot but also non-combustible ash, which cannot be removed through regeneration. This ash build-up, combined with excessive soot loading from frequent short journeys, failed regeneration cycles, or issues with associated engine management sensors (such as the differential pressure sensor or exhaust gas temperature sensor), can lead to blockages. Common failure modes for the Ford Focus 1.6 TDCi DPF include reduced exhaust flow, increased back pressure, and eventually, a completely blocked filter. Internal damage, such as melting or cracking of the ceramic substrate, can also occur, often as a result of prolonged high temperatures from over-fuelling, injector malfunctions, or an incorrectly executed forced regeneration. A blocked DPF will typically manifest as reduced engine power, increased fuel consumption, activation of dashboard warning lights (including the DPF warning light or engine management light), and potentially putting the vehicle into ‘limp mode’.

What this diesel particulate filter (DPF) fits

This DPF is suitable for the Ford Focus 1.6 TDCi models manufactured between 2005 and 2010, equipped with engine codes HHDA and HHDB. It is designed to meet Euro 4 emission regulations. The original equipment (OE) part number is BM11071, with an alternative part number of 1731154. Confirming these details against your vehicle’s specifications is crucial for correct fitment and optimal performance.

At Gap Turbos, we provide a specialist DPF cleaning service for this specific unit. Our comprehensive process involves advanced ultrasonic and thermal cleaning techniques, meticulously designed to effectively remove both soot and non-combustible ash deposits from the DPF’s intricate ceramic substrate without causing structural damage. This method is a significantly more economical and environmentally friendly alternative to purchasing a brand-new replacement DPF, typically offering savings of 70-90% of the cost, provided the internal substrate is intact. We also offer advice on mobile cleaning services and can guide you on appropriate diagnostic and forced regeneration procedures where applicable. It is important to note that DPF removal is strictly illegal in the UK and will result in an immediate MOT failure, alongside potential fines. For a precise quote tailored to your DPF cleaning needs and comprehensive details on our warranty, please contact us directly. We are a Birmingham specialist since 1986.

Specifications

Vehicle fitment

• Ford Focus 1.6 TDCi

Common faults & troubleshooting

• Reduced engine power / Limp mode activation: Likely a heavily blocked DPF restricting exhaust flow. Diagnose DPF pressure sensor readings.
• DPF warning light or engine management light on dashboard: Indicates DPF blockage or a fault within the DPF system. Check for fault codes using a diagnostic tool.
• Increased fuel consumption: Engine working harder against exhaust back pressure. Verify DPF saturation levels.
• Strong exhaust smell or excessive smoke: Could indicate a failed regeneration attempt or damaged DPF substrate. Inspect DPF for physical damage.
• Engine struggling to start or stalling: Severe DPF blockage can create extreme back pressure. Test exhaust back pressure directly.

Fitting notes for this unit

• Gasket Replacement: Always replace the DPF inlet and outlet gaskets with new items to ensure a leak-free seal. Reusing old gaskets can lead to exhaust leaks and incorrect sensor readings.
• Sensor Check: Carefully remove and inspect the differential pressure sensor and exhaust gas temperature (EGT) sensors. Consider replacing them if they show signs of damage or corrosion, as they are critical for DPF function.
• Torque Settings: Adhere strictly to manufacturer’s torque specifications for all DPF mounting bolts and clamp bands. Overtightening can strip threads, while undertightening can cause leaks.
• Eolys Fluid: For Euro 4 models, check the Eolys fluid (DPF additive) level and top up if necessary. The system needs this fluid for effective regeneration. Reset the additive counter via diagnostics after refilling.
• Diagnostic Reset: After fitting a cleaned DPF, it is crucial to perform a diagnostic reset of the DPF learned values and differential pressure sensor adaptations using appropriate diagnostic equipment. This tells the ECU the DPF is clean.
• Forced Regeneration: Post-installation, perform a forced regeneration or a suitable road test to allow the ECU to adapt to the newly cleaned DPF and ensure proper operation.
