BMW X5 Diesel Particulate Filter DPF

A diesel particulate filter (DPF) is a key exhaust component found in diesel engines, including all modern BMW X5 series. Its job is to capture and store soot particles that form during combustion, preventing them from being released into the air. The DPF works alongside the catalytic converter, EGR system, and other components to reduce harmful diesel exhaust emissions in compliance with Euro regulations.

A blocked DPF can cause several symptoms, including:

• A warning light on the dashboard
• Loss of power during acceleration
• Poor fuel economy
• Increased exhaust pressure
• Fault codes from the DPF sensor
• Visible smoke from the tailpipe

Ignoring these issues can lead to expensive damage to the turbo, pipework, or even the manifold. A full diagnostic check at a garage is advised if you see any of these signs.

There are a few reliable methods for cleaning diesel particulate filters:

• Passive regeneration: Occurs naturally when driving at higher speeds
• DPF forced regeneration: Requires a diagnostic tool, often done at a garage
• Professional DPF cleaner service: Involves removing the unit for chemical or heat-based cleaning

For filters that are too far gone, replacement is often more cost-effective in the long run.

Regeneration is the process of burning off the soot stored inside the filter. It can be passive, active, or forced. Without proper regeneration, soot particulate builds up and restricts airflow, increasing engine strain. Keeping your regeneration cycle healthy ensures better engine response and lower long-term fuel consumption.

To confirm the right part, gather your BMW model, engine code, bhp rating, and xDrive status. These details ensure you get the right mounting type, fittings, and Euro compliance level. You can also use our contact form or speak to our support team for quick guidance.

If you're confident with mechanical tasks, you may handle the DPF removal and installation process yourself. Each Krosfou DPF kit includes proper mounting hardware, so it’s ready to go. However, to preserve your warranty and ensure the correct system calibration, we recommend using a qualified garage—especially for newer models.

Our kits typically contain:

• The filter unit (with or without integrated cat)
• A full mounting kit with gaskets and bolts
• Technical specs including model, fitment, and compatibility
• Warranty documentation and installation support

Each item is shipped in pristine condition, ready for direct installation with no adjustments needed.

You can buy online directly from Krosfou.fr, the manufacturer. We maintain accurate stock listings for all BMW X5 DPF applications—standard and mild hybrid alike. Whether you're looking for a quick swap, an upgrade, or a bestseller, our team can help you choose the right product.

Pricing varies depending on whether you need a basic DPF, a model with an integrated catalyst, or a full emission system upgrade. Most of our options start at around €300. We offer excellent value with direct-from-brand pricing, full kits, and a warranty to match.

Yes, all Krosfou parts meet Euro 4, Euro 5, and Euro 6 standards. If you’re driving a Euro 4 fits BMW model, rest assured—we have a perfect match. Our units undergo full testing under UNECE Regulation R103 and use high-grade materials for consistent performance.

We do. Our catalog includes filters for 2020 BMW and newer G05/G06 series with MHEV (mild hybrid electric vehicle) systems. These units often differ slightly in pipe and manifold layout, so we recommend reaching out to confirm compatibility.

Not exactly. A DPF traps particulate matter, while a catalytic converter breaks down gases. Many filters now come as a combined cat-DPF system to save space and improve efficiency. These integrated units are commonly used in newer diesel cars, including the X5.
