Iveco Daily Diesel Particulate Filter DPF

The DPF on the Iveco Daily is a critical exhaust component designed to capture harmful fine soot particles emitted by incomplete combustion of diesel fuel. It helps reduce pollution by filtering these particles before they leave the vehicle’s exhaust system.

Common signs of a clogged or damaged DPF include:

• Loss of power during startup or acceleration
• Frequent engine stalling, especially at startup
• Illuminated DPF warning light on the dashboard
• Increased fuel and engine oil consumption
• Slower vehicle response
• Black smoke emitted from the exhaust

Ignoring these symptoms can cause further engine damage.

The main causes include:

• Normal wear from soot and ash accumulation
• Poor combustion leading to incomplete soot burn, especially if exhaust temperature stays below 550°C
• Blocked EGR system or degraded exhaust components such as catalytic converter or turbo
• Predominantly short trips or city driving with insufficient heat for passive regeneration

The DPF system uses sensors measuring differential pressure and temperature to monitor its condition and trigger regeneration when needed.

The DPF is located downstream of the turbocharger and includes an integrated catalytic converter.

• Filtration: It traps soot and fine particles in the diesel exhaust gases.
• Regeneration:
  • Passive regeneration: Occurs automatically at high exhaust temperatures over 550°C, common during highway driving.
  • Active regeneration: Triggered by the engine control unit if clogging is detected, injecting fuel to raise temperature and burn off soot. This can increase engine oil level.
  • Additives may be used to lower combustion temperature of particles.
• Sensors continuously monitor pressure and temperature to control regeneration processes.

If you notice problems related to your DPF, consider the following steps:

• Get an immediate diagnostic check from a professional mechanic to confirm clogging.
• Perform forced regeneration by either driving at high speed for a long distance or using diagnostic tools like Autel MaxiCOM MK808BT to initiate regeneration safely.
• Alternative cleanings include hydrogen decarbonization to environmentally remove soot and boost engine/turbo performance, or chemical products (use cautiously to avoid sensor contamination).
• If cleaning fails, replace the DPF with a new one from a reputable supplier (avoid refurbished parts).

Always try cleaning and regeneration before considering full replacement to avoid unnecessary costs.

Preventive measures include:

• Regular maintenance and technical inspections
• Driving longer distances at sustained speeds to allow passive regeneration
• Using quality diesel fuel to minimize soot production

These practices help maintain the DPF's function and extend its lifespan.

Yes, many users perform forced regeneration via diagnostic tools that prepare the vehicle and heat up the DPF to burn off soot safely. Online tutorials and videos guide how to proceed, but it is essential to:

• Use compatible and reliable diagnostic equipment
• Follow manufacturer instructions carefully
• Ensure vehicle is in good running condition before attempting regeneration

If unsure, consult a professional mechanic for checking and repairs to avoid triggering error codes or causing further damage.

For reliable and high-performance new DPFs and catalytic converters that meet manufacturer standards and European regulations, choose original parts from trusted suppliers. These products come with guarantees, professional technical support, and ensure compliance with environmental standards.

• Look for products made with stainless steel INOX 409 and high-quality monoliths with thin-layer coatings for durability and performance.
• Registered warranties (e.g., 3 years limited to 100,000 km) and free return policies improve purchase security.
• Professional advice and installation manuals are often available to assist mechanics and users.

Always avoid refurbished or low-quality parts and seek expert advice for installation and maintenance.
