Mercedes CLS-Class Diesel Particulate Filter DPF

The DPF in Mercedes CLS-Class diesel vehicles is positioned on the exhaust line, placed after the catalytic converter. It is made of ceramic material designed to effectively trap fine particles produced during diesel combustion.

The Diesel Particulate Filter is compatible with various Mercedes CLS-Class diesel variants, including:

• Mercedes CLS 320D
• Mercedes CLS 350D
• Other models such as E280 TD, E300, and E320 3.0 TD CDI

All these models comply with Euro 4 emission standards or higher, making the DPF an essential component for pollution control.

The cost of a DPF for Mercedes CLS-Class diesel engines varies widely depending on the type of part. While prices can range significantly, new adaptable silicate-based DPF units usually cost around €314 excluding VAT (£376.80 VAT included).

Prices depend on whether the part is new and OEM equivalent or other types, but Krosfou offers high-quality, original parts with a 3-year warranty.

Proper maintenance of the DPF includes regular driving conditions that allow for active regeneration, which burns off soot and restores filter efficiency.

• Drive at sustained speeds regularly to enable natural regeneration.
• Use quality fuel and ensure the engine management system is functioning correctly.
• Observe any warning lights related to the DPF and respond promptly.

If active or passive regeneration does not work, professional cleaning or replacement might be necessary.

The DPF warning light can be reset after a successful regeneration cycle or after replacement. This typically requires the use of dedicated diagnostic tools to reset the system's sensors and warning lights properly.

If the warning light remains on, it is advisable to check for faults with the pressure sensor or regeneration system and address any underlying issues to avoid damage.

Krosfou offers a range of new, original DPFs manufactured with high-grade quality standards:

• Manufactured in INOX 409 stainless steel for durability
• Equipped with high-quality ceramic monoliths with advanced coating technology
• Certified by TÜV SÜD, ensuring compliance with and often exceeding OEM standards
• Offered with a 3-year warranty covering up to 100,000 km usage
• Available for many vehicle models including Mercedes CLS-Class with fast delivery options

These features ensure an efficient, long-lasting filtration solution that supports effective exhaust gas cleaning and engine performance.

The DPF filters soot and particulate matter from diesel exhaust gases, preventing harmful emissions from entering the atmosphere. Positioned after the catalytic converter, it traps fine particles on a ceramic filter substrate.

• During regeneration cycles, accumulated soot is oxidised or burned off.
• This process helps maintain optimal exhaust flow and engine efficiency.
• Regular function of the DPF is essential for emissions compliance and engine health.

Proper operation also prevents increase in fuel consumption and power loss due to blockage or malfunctioning.

If the DPF warning light remains illuminated despite normal driving, or if the filter becomes blocked, consider the following steps:

• Check for any fault codes related to regeneration or pressure sensors using a diagnostic tool.
• Ensure that active regeneration has been given sufficient time and conditions to complete.
• Consult a garage or professional to perform a manual or forced regeneration if required.
• If cleaning is ineffective, replacement of the DPF might be necessary to restore proper function.

Timely attention can prevent more serious damage to the exhaust system and avoid costly repairs.

Always use original or OE-equivalent quality DPF replacements to maintain emissions standards and car performance.
