BMW X4 Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in BMW X4 diesel models captures fine soot particles from exhaust gases to meet Euro emission standards such as Euro 6. It is a key part of the exhaust and emission system, designed to reduce harmful pollutants released into the atmosphere.

DPFs are fitted on various BMW X4 diesel variants, including but not limited to:

• BMW X4 2.0 d xDrive (G02/F98) with engine B47D20A, 190 hp, Euro 6 standard (2018-2020)
• BMW X4 (F26) xDrive35d 3.0 with engine N57 D30 B, 313 hp
• Other diesel versions like 20d, 30d, sensitive to short trip usage

The DPF part numbers and specifications differ by model and engine type, ensuring proper fit and performance.

The DPF collects soot particles during diesel combustion, which must be periodically burnt off by regeneration to prevent clogging and failure. Regeneration types include:

• Passive regeneration: Exhaust gas temperature rises automatically to burn soot during normal driving
• Active/natural regeneration: Requires sustained driving at speeds above ~60 km/h (~60 mph) for the DPF to regenerate
• Forced regeneration: Executed via special BMW software (Rheingold ISTA-D) to clean the DPF regardless of soot level; requires stable speeds (~60 mph)

Proper regeneration ensures DPF durability with an expected lifetime of about 125,000 to 185,000 miles (200,000 to 300,000 km).

Signs of a clogged or faulty DPF include:

• DPF warning light illuminated on the dashboard
• Reduced engine performance and increased fuel consumption
• Vehicle entering limp mode or restricted power mode

These issues often arise from frequent short trips, low-speed driving, or excess soot accumulation, causing filter blockage.

To prevent, regular highway driving over 60 km/h is recommended for proper DPF regeneration.

Maintenance and cleaning options include:

• Diagnostic checks using OBD or BMW ISTA software to monitor soot levels
• Forced regeneration via BMW software if soot exceeds 10-15%
• Chemical cleaning for advanced ash blockages without complete removal
• Replacement when the DPF is irreversibly clogged with ash, followed by reprogramming

Regular preventive maintenance helps extend DPF life and avoid costly replacements.

BMW X4 DPF prices vary depending on model and supplier. For example, some DPFs for the X4 3.0 L variant weigh around 8.36 kg and cost approximately €726. Krosfou offers high-quality, new original DPFs manufactured in Europe with a 3-year warranty, available for professional and retail customers.

• Products are shipped from factory directly with options for express delivery
• Store DPFs in their original packaging and dry environment to ensure product integrity
• Contact suppliers for specific model compatibility and pricing details

Always ensure DPF compatibility with vehicle Euro standard and engine code before purchase.

While some additives claim to assist DPF regeneration by helping burn soot at lower temperatures, BMW and maintenance experts generally recommend relying on proper driving habits and diagnostic regeneration procedures instead.

• Additives are not universally endorsed and may have varying effectiveness
• Routine forced regeneration via BMW software is a safer and more reliable method
• Always consult your vehicle’s service manual or a professional mechanic before using any chemical additives

Maintaining proper engine and exhaust conditions remains the best practice for DPF health.
