What is a diesel particulate filter ?

A diesel particulate filter (DPF) is a critical part of your vehicle's exhaust system. It traps soot and ash from your Audi's diesel engine before they exit the exhaust pipe, reducing harmful emissions. Without proper regeneration—either passive or active—this filter can clog, causing pressure buildup, loss of performance, and increased fuel consumption.

What are the signs that your DPF is blocked ?

A blocked DPF causes several performance issues. Watch out for:

A warning light or system error message

Reduced turbo power or sluggish acceleration

Excessive smoke or exhaust gas smell

Rising fuel usage on short or daily drives

If these symptoms persist, it's important to get your DPF checked to avoid further damage to the engine or oxygen sensor system.

How do I clean or regenerate it ?

Cleaning depends on the level of blockage. Here's how the process works:

Passive regeneration occurs when you drive at higher speeds for longer periods, like on the motorway. The consistent exhaust manifold temperature helps burn off soot.

Active regeneration is automatically triggered by the ECU, injecting extra fuel to raise the exhaust temperature and burn particulates.

If neither works, a technician can complete a manual or forced regeneration using specialized equipment or a DPF cleaner.

Keeping track of your regeneration history helps you stay ahead of problems.

What does Audi A3 DPF error code 2458 mean ?

This specific error code points to reduced filter efficiency. It usually indicates that regeneration has not completed successfully, or that there's excessive soot buildup or a failed temperature sensor.

Use a diagnostic tool to review the DPF data. If regeneration attempts are repeatedly interrupted, it may be time for an update, professional cleaning, or a complete replacement.

When should the DPF be serviced or replaced ?

Under normal conditions, your Audi A3's particulate system will self-regenerate regularly. However, frequent short trips or cold starts may prevent the process from completing.

We recommend:

A technical inspection or check every 20,000 to 30,000 km

Full replacement between 120,000 and 160,000 km, depending on your driving habits and fuel type

Logging your service history to monitor system health

Can I legally remove the DPF from my Audi A3 ?

DPF removal is not only illegal under current Euro emission standards, but it will also cause your Audi to fail its MOT or Contrôle Technique. It may trigger ongoing warning lights and engine management issues.

At Krosfou, we provide OEM-quality, certified solutions for legal replacement, preserving your vehicle's resale value and environmental compliance.

What's the typical price of a new Audi A3 filter ?

The price varies depending on the engine type, platform, and whether you're buying just the filter or a complete kit.

Basic units start at €250

Full kits include the main DPF, gaskets, clamps, mounting set, and sometimes a manifold adapter or sensor pipe

Discounts are available for garages, bulk buyers, or trade professionals

Our filters are built from high-end materials like silicon carbide and cordierite, offering long-term durability and performance.

Where can I buy a DPF for my Audi A3 online ?

You can order directly from Krosfou.com for the best service and fast delivery on this item. We stock a wide range of diesel particulate filters compatible with:

Audi A3 TDI 1.6, 1.9, and 2.0 engines

Generations including 8P, 8V, and 8YA

All fuel types and engine codes (CLHA, CRLB, BMN, etc.)

You'll also find our parts on platforms like eBay, but ordering directly from us ensures fast support and full access to fitment and technical data.

Which Audi models does your DPF range cover ?

We support a wide selection of Audi A3 diesel variants:

2015 Audi A3 and earlier: 1.6 TDI (CLHA, CXXB), 2.0 TDI (CUNA, CRLB), 1.9 TDI (BLS, BMM)

Compatibility across exhaust manifold and mounting types

You can enter your vehicle information on our site to get matched with the correct item.

Is a catalytic converter the same as a DPF ?

No. A catalytic converter (or cat) deals with gas-based pollutants like nitrogen oxides, while a DPF traps physical particles like soot and ash. Many Audi A3 systems combine both in one assembly. We offer both individual and dual-purpose units depending on your setup.

What's included in your DPF kits ?

Our complete DPF kits include:

A diesel particulate filter built to OEM specifications

Gasket sets, mounting hardware, and sometimes a sensor pipe or manifold fitting

All necessary installation equipment to ensure proper alignment and seal

Each listing clearly outlines what's included so there are no surprises. You can also contact us for technical advice.

How can I confirm my DPF is working correctly ?

To confirm your filter is still operating efficiently, use a diagnostic tool to check:

Recent regeneration status

Temperature data from the DPF sensors

Stored error codes such as P2002 or 2458

Real-time soot levels and pressure readings

If you're unsure, bring your car to a professional who can verify functionality and recommend whether a replacement is necessary.
