BMW X4 Diesel Particulate Filter DPF

The diesel particulate filter (DPF) on BMW X4 diesel models is designed to capture soot particles from exhaust gases to reduce harmful emissions. It works by trapping these particles in a ceramic honeycomb structure and periodically burning them off at high temperatures to regenerate the filter.

The DPF captures soot in a ceramic cell structure. It regenerates naturally when the exhaust temperature reaches about 550°C, burning off the particulates. If the filter becomes clogged, active regeneration injects fuel post-combustion to raise temperature and clean the DPF automatically.

The DPF is featured on the following diesel BMW X4 models:

• X4 F26 xDrive35d (3.0 diesel, 313 hp, engine N57 D30 B)
• X4 2.0 d xDrive (G02 F98, 2.0 diesel, 190 hp)
• X4 xDrive20d (190 hp diesel)
• X4 M40d xDrive (326 hp diesel)

These models benefit from OEM-standard DPFs designed to meet emissions regulations and ensure durability.

Regular maintenance of the DPF includes:

• Allowing regular highway driving for passive regeneration at high exhaust temperatures.
• Utilising forced regeneration services via specialist equipment if the filter is clogged.
• Ensuring timely diagnostics and cleaning to prevent buildup and damage.

Professional cleaning and forced regeneration tools are recommended especially for models like the X4 xDrive20d and X4 M40d.

Common issues include:

• DPF clogging due to frequent short trips and insufficient high-temperature operation.
• Warning lights and reduced engine performance when regeneration fails.
• Increased fuel consumption during forced regeneration processes.

Regular servicing and proper driving habits are key to avoiding these problems.

Replacement times vary by model, for example:

• X4 M40d xDrive (326 hp): approximately 10 hours and 10 minutes.
• Other models may require less or more time depending on engine specifics and setup.

We advise consulting a qualified mechanic for an accurate labour estimate.

Some additives claim to aid in DPF maintenance by improving combustion or reducing soot accumulation. However, their effectiveness can vary, and they should only be used according to manufacturer guidance and after consultation with a trusted mechanic.

• Always verify compatibility with your specific BMW X4 diesel model.
• Do not rely solely on additives to fix serious DPF issues.

Proper driving and professional servicing remain essential for DPF longevity.

Genuine new DPFs made from premium stainless steel with advanced ceramic monoliths are available directly from trusted manufacturers. Look for products certified by automotive authorities such as TÜV Süd that ensure superior quality and compliance with European regulations.

• These DPFs come with warranties up to 3 years or 100,000 km.
• Technical support and installation guides are often provided.
• Fast shipping options and professional customer service can ease the purchasing process.
