Ford B-Max Diesel Particulate Filter DPF (2012-2017)

The Diesel Particulate Filter (DPF) in the Ford B-Max, typically equipped with the 1.6 TDCi engine (95 hp, code CB2), captures harmful soot particles generated during combustion to reduce harmful emissions. It is a key component of the vehicle's emission control system.

Common signs of a clogged DPF include:

• Illumination of the check engine light or DPF warning light on the dashboard.
• Loss of engine power caused by exhaust gas blockage.
• Soot level reaching critical amounts above 50 g, meaning the filter is clogged and automatic regeneration becomes ineffective.

DPF regeneration is the process of burning off accumulated soot to keep the filter efficient. It happens in several ways:

• Automatic regeneration: occurs periodically without driver intervention when soot levels reach between 40-50 g.
• Forced regeneration: can be initiated using diagnostic tools or a specific driving mode ("Maintenance regeneration during driving") when soot exceeds 50 g.

This process helps maintain optimal engine and emission system performance.

To prevent DPF clogging and maintain performance, consider the following maintenance tips:

• Chemical cleaning: Use specific DPF cleaning products by pouring them into the filter, allowing them to act, and then running the engine at idle to burn off residues.
• Use preventive additives:
  • Eco-10000: Apply about once a year to clean the system and reduce soot buildup.
  • C99: Recommended for use at each fill-up, especially in high-clogging risk areas, such as Guadeloupe.
• Professional engine and DPF cleaning services are also an option for severe contamination.

If the DPF becomes irreversibly clogged or damaged, replacement is necessary. DPFs for Ford B-Max 1.6 TDCi (CB2) models are available from quality suppliers. Replacement prices vary depending on specifications. It is important to replace the DPF with parts conforming to manufacturer standards for proper performance.

Diagnostic tools compatible with the Ford B-Max 1st generation include OBD applications like Carista, which can scan and read alerts related to the engine, ABS, airbag, and specifically the DPF system. These tools help detect DPF clogging symptoms and manage regeneration procedures.

The official Ford manuals also provide guidance on interpreting DPF-related warnings and system maintenance.

Yes. Short-distance drives and city driving conditions tend to favor soot accumulation because the engine and DPF may not reach optimal operating temperatures needed for regeneration. Longer highway drives at steady speeds (e.g., above 50 mph) help the DPF burn off soot more effectively, reducing clog risk.

• Leaving the engine to complete a regeneration cycle during drives is recommended when you notice DPF warning lights.
• Regular use of regeneration-friendly driving conditions prolongs DPF life and helps keep the system healthy.

Removing the DPF from a Ford B-Max is not recommended as it leads to increased pollution and usually fails vehicle inspection tests such as the MOT. Detection of a missing or removed DPF will likely cause the vehicle to fail emission-related checks.

• DPFs are a mandatory part of the vehicle’s emission system to meet legal environmental standards.
• It is best to keep the DPF installed and properly maintained to ensure compliance and optimal engine performance.
