Fiat Fiorino Diesel Particulate Filter DPF 3 (Iii) (2007-2025)

The Diesel Particulate Filter (DPF) on the Fiat Fiorino 3 is an essential component of the 1.3 Multijet diesel engines. It filters fine, carcinogenic particles from the exhaust gases to meet Euro 5 and Euro 6 emission standards. Positioned after the turbo in the exhaust line, the DPF consists of a silicon carbide filter combined with an integrated catalytic converter, helping reduce pollution and improve air quality.

The DPF is installed on several diesel-powered Fiat Fiorino 3 versions since 2009, including:

• 1.3 D Multijet 75 HP (55 kW) – from 07/2009, compliant with Euro 5 & 6
• 1.3 D Multijet 95 HP (70 kW) – from 2009, Euro 5 & 6 standards
• 1.3 D Multijet 80 HP (59 kW) – from 03/2015, Euro 6 version with automatic chain tensioner

Note: Petrol versions like the 1.4 73 HP do not have a DPF.

The DPF traps soot particles from diesel exhaust gases using a silicon carbide filter. Its regeneration is controlled by the engine control unit, which monitors sensors for pressure, temperature, and oxygen. When soot accumulates, the system injects fuel to burn off the particles at high temperatures in a process called regeneration. This can be passive or active depending on conditions. If regeneration fails, the vehicle enters a degraded mode and a warning light appears.

Common issues with the DPF include premature clogging, especially in urban driving conditions where low speeds prevent proper regeneration. Symptoms of DPF faults include:

• Engine warning light activation
• Loss of engine power
• Entry into degraded mode with reduced performance

Frequent short trips can affect DPF longevity, requiring regular monitoring and maintenance.

DPF maintenance involves preventing clogging by regular driving at operating temperatures to enable regeneration. In case of failure, professional cleaning products can be used to clear blockages. Replacement includes changing silent blocks, flex pipes, and exhaust manifold gaskets as needed. Full tutorials and installation guides are available to assist with mounting. Tools for diagnostics help reset DPF-related errors, but removal of the DPF is illegal and discouraged.

• New original DPFs are manufactured to strict European standards using high-grade ceramics and stainless steel
• Krosfou offers premium quality DPFs with a 3-year warranty
• Replacement cost can be around €900 including parts and labor

You can confirm your vehicle’s DPF presence by checking the engine type and model year:

• 1.3 Multijet diesel engines from 2009 onwards are equipped with a DPF
• The engine control unit monitors DPF regeneration and sensor data
• The owner’s manual or vehicle documentation also specifies the presence of the particulate filter

For more precise confirmation, use your VIN number to verify parts compatibility through professional catalogs or authorized dealers.

The DPF has differential pressure sensors located around the DPF unit in the engine compartment to monitor soot accumulation. Additional sensors include:

• Temperature sensors before and after the DPF
• Oxygen (lambda) and NOx sensors integrated into the exhaust system

These sensors provide real-time data to the engine control for regulating DPF regeneration and ensuring proper exhaust gas flow.
