Lancia Delta Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) is an essential component of Lancia Delta Diesel engines, particularly for the 1.6 Multijet models. It filters soot particles from exhaust gases to comply with Euro 5 emission standards. The DPF is made from silicon carbide with a honeycomb porous structure that traps carbon particles, reducing pollution and supporting environmental regulations.

The DPF is specifically used on the Lancia Delta III (844) Diesel versions, mainly the 1.6 D Multijet engines with power outputs ranging from 105 CV to 120 CV. The applicable engine codes include 198 A2.000, 844.AXC11, and 844.AXC1A. It is fitted on various engine variants between model years 2008 to around 2014, generally for 5-door hatchback body styles.

Signs of a clogged or defective DPF include:

• Increased fuel consumption.
• Loss of engine power.
• Illumination of the Check Engine light on the dashboard.
• Specific amber warning light for DPF regeneration during vehicle start.
• Accumulation of soot blocking exhaust gases flow.

If you experience these symptoms, it's important to check the DPF condition promptly to avoid further engine damage or reduced fuel efficiency.

The DPF regenerates by burning trapped soot particles to restore filtering capacity. There are two main methods:

• Automatic regeneration: The vehicle's ECU monitors differential pressure sensors before and after the filter and triggers temperature increase in exhaust gases, often aided by catalytic converter additives that facilitate rapid carbon oxidation.
• Manual regeneration: Driving continuously for 20-30 minutes at speeds between 60 to 80 km/h can initiate soot burning. Alternatively, diagnostic tools like VCDS can force regeneration.

Use of special cleaning additives accelerates particle combustion and helps maintain filter health. Regular longer trips are recommended for effective DPF cleaning and longevity.

Replacement is generally recommended between 130,000 and 200,000 kilometers to prevent failures. Exact mileage can vary depending on vehicle usage conditions. Always verify OEM part numbers before fitting a replacement DPF. Proper installation by a qualified professional is strongly advised.

Quality Diesel Particulate Filters manufactured in Europe with strict adherence to OEM specifications are available online. They are made with stainless steel (INOX 409) casing and feature high-performance silicon carbide monoliths treated with advanced coatings for durability and efficiency.

Look for products with proper certifications such as E24-103R, and avoid items labeled only with CE mark, which is not an automotive homologation. Ordering from reputable manufacturers ensures product reliability, a 3-year warranty, and compliance with European regulations.

• Check product compatibility by providing your Lancia Delta model and engine code (e.g., 198 A2.000).
• Ensure the seller offers clear shipping terms, return policies, and warranty coverage.

A properly functioning DPF helps maintain optimal engine and fuel system operation while reducing harmful emissions. However, when a DPF becomes clogged, fuel consumption can increase significantly and engine power may drop, as the engine must work harder to push exhaust gases through the obstructed filter.

Regular maintenance and proper regeneration of the DPF are vital to avoid such issues and to ensure your vehicle runs efficiently with lower fuel consumption and emissions.

When selecting a DPF for your Lancia Delta, consider the following factors:

• Exact engine type and code to ensure fitment (e.g., 1.6 Multijet 120 CV - 198 A2.000).
• Certification and compliance with Euro 5 emission standards.
• Material and build quality (stainless steel casing with high-grade silicon carbide substrate).
• Warranty and after-sales service.
• Compatibility with your vehicle’s sensors and ECU for correct regeneration management.
• Professional installation to maintain vehicle warranty and proper functionality.

Choosing a DPF from a trusted manufacturer with proven quality ensures durability, optimal performance, and environmental compliance.
