Mercedes Sprinter Diesel Particulate Filter DPF

A Diesel Particulate Filter (DPF) is part of your Mercedes Sprinter's exhaust system. Its primary role is to trap soot and particulate matter from combustion gases before they exit the tailpipe. This helps your van meet strict emission standards and keeps your diesel engine operating under optimal conditions.

Every time you drive—especially short trips—fine particles accumulate in the filter. Once soot levels reach a certain threshold, the regeneration process activates to burn them off and restore flow.

Regeneration is a crucial DPF function. There are two types:

Passive regeneration: Occurs during long-distance driving (like motorway journeys) when high exhaust gas temperatures naturally burn off soot.

Active regeneration: Automatically triggered by the DPF monitor when soot levels increase. The ECU adjusts fuel injection to raise exhaust temperature and initiate burning.

Both types are essential to maintaining DPF performance. Interrupting this cycle—by cutting trips short or driving at low speeds—can leave regeneration incomplete, leading to a blocked condition.

Signs that your DPF may be full or struggling include:

• Dashboard warning lights or messages
• Sluggish acceleration and lower engine response
• Increased fuel consumption
• Excess smoke or black soot from the exhaust
• A noticeable change in engine noise or operation

These are clear signals to enter diagnostic mode or seek professional service attention before more serious issues develop.

Here are a few DIY and professional options for cleaning:

• Use a scan tool to trigger a manual regeneration
• Add a specialised DPF cleaning fluid to the fuel or apply directly through the pipe
• Take the vehicle on a highway drive to allow automatic regeneration to complete uninterrupted

Follow the vehicle's instruction manual and monitor soot levels with a diagnostic tool. If these methods don't work, it may be time for a replacement or a deep-clean service from a mechanic.

Sprinter DPF faults are often caused by:

• Short journeys that prevent full regeneration
• Use of poor-quality diesel
• Faulty DPF sensors or monitor failures
• Clogged muffler or backpressure buildup in the manifold

Keeping your DPF in top condition reduces the risk of performance issues and long-term engine damage. If left unchecked, accumulation can trigger codes, limp mode, and affect engine oil condition.

Use a diagnostic scan tool to check for trouble codes. P2002, for example, is a common code for DPF efficiency failure. A qualified mechanic will:

• Check exhaust manifold pressure and air flow
• Measure soot and ash accumulation levels
• Inspect sensors and catalyst operation

Routine checks reduce the chance of system failure and keep regeneration cycles functioning normally.

Mercedes-Benz recommends evaluating the DPF system after 100,000 miles, particularly if you're experiencing:

• Recurrent regeneration failures
• Decreased vehicle performance
• Physical signs of soot escape at the tailpipe

If cleaning no longer improves flow, opt for a high-quality DPF replacement product that fits your vehicle and meets EEC standards. Krosfou units include all necessary components in a full mounting kit.

At krosfou.co.uk, we offer:

• Fast, direct online ordering
• Spare parts for all major Sprinter diesel models
• DPF soot filters and catalytic converters
• Full installation kits for a complete solution
• Customer service and technical support

Our filters are designed to meet or exceed original manufacturer quality at a lower price, with reliable UK delivery and real-time stock availability.

Replacement prices depend on your Sprinter model, engine configuration, and whether you choose an aftermarket or OE-spec unit. Krosfou filters are competitively priced and built to last:

• Lower cost than main dealer alternatives
• Manufactured to match Mercedes-Benz engineering standards
• Each unit is ready to install—no hidden extras

Our products offer long-term value and reduced downtime.

Continuing to drive with a full or blocked DPF can:

• Increase engine strain and exhaust temperatures
• Trigger limp mode or acceleration limits
• Lead to catalytic converter damage

If the DPF warning light stays on and manual regeneration fails, don't ignore it. Stop, run a diagnostic check, and take corrective action promptly.

To extend your filter's lifespan:

• Drive at steady speeds for longer periods
• Avoid idling and short, low-speed trips
• Use premium fuel and low-ash engine oil
• Follow DPF regeneration instructions and monitor system behaviour

Simple habits help avoid blockages and reduce soot buildup over time.

• Expertly manufactured diesel particulate filter DPF solutions
• EEC-approved components and soot particulate filter options
• Automatic regeneration performance and superior quality materials
• Trusted by Sprinter owners, fleet drivers, and garages
• Every purchase includes a 3-year warranty

We combine advanced filtration design with value, service, and direct UK distribution. From spare part supply to expert guidance, Krosfou helps you keep your diesel vehicle running reliably.
