Audi A6 Diesel Particulate Filter DPF

A diesel particulate filter (DPF) is a key part of your Audi's exhaust system, designed to capture solid particles like soot. Unlike a catalyst that neutralizes gases, this soot particulate filter physically traps debris before releasing air. It cleans itself using a process called regeneration.

Krosfou filters are made using high-performance materials like cordierite or silicon carbide — the same ones trusted by BMW, TDI diesel, and TFSi Quattro drivers alike. That means less fuel waste and better engine efficiency.

Modern Audi models let you check the filter's condition using onboard diagnostics. Just connect an OBD tool or VCDS and monitor:

Sensor pressure before and after the filter

Lambda feedback for clean combustion

Exhaust gas temperature, key to the regeneration process

All this helps you avoid performance issues and high fuel consumption.

Your vehicle uses a built-in regeneration process to keep the DPF from getting blocked. This can happen:

Passively, during long highway drives

Actively, triggered by the ECU

Manually, using diagnostic tools or your garage

Some drivers even use YouTube tutorials to initiate regenerate cycles using VCDS.

If your DPF is clogged, here's how to get it clean:

Cruise for 20 minutes at speed to encourage passive regeneration

Add a cleaning additive to your fuel tank

Try professional ultrasonic or thermal cleaning

Opt for a full replacement if it's beyond help

Short trips lead to soot buildup

Broken sensors cause false alerts

Failing EGR coolers or valves increase blockage risk

Excess backpressure can trigger limp mode

If you get fault codes like P2002, check your DPF, air intake, and surrounding parts like the suspension or brake system if handling is affected.
