Audi A5 Diesel Particulate Filter DPF 1 (I) (2007-2016)

A DPF captures soot particles from diesel combustion in your exhaust system, reducing harmful emissions. Over time, these filters clog and require cleaning, regeneration, or replacement. Our brand new units are designed to restore your vehicle's emissions system to its original performance.

The DPF also plays a crucial role in keeping your catalytic converter efficient. A malfunctioning DPF can affect the entire exhaust line and lead to engine performance issues, making regular maintenance essential.

Regeneration occurs automatically during long drives. This burns off trapped particles using exhaust gas heat. For persistent clogs, a DPF cleaning kit or professional service may be required. Always use low-ash engine oil and consider supplementary fuel treatments to prevent buildup.

Some models allow for forced regeneration using diagnostic tools. Consult your vehicle manual or speak with a qualified garage to find out if your car supports this option. Periodically checking for engine fault codes can help prevent more serious DPF issues.

Key symptoms include:

• Dashboard alerts
• Loss of power or limp mode
• Increased diesel usage
• Irregular exhaust smell
• Frequent fan operation after shutdown

Unaddressed blockage increases pressure in the manifold, affecting your EGR valve, sensors, and even the catalytic converter. It can also lead to increased back pressure in the engine, which may cause turbocharger damage over time.

Consult your vehicle's manual, then perform a long, steady-speed drive. If alerts persist, scan for error codes. In advanced cases, replacing the DPF may be necessary. Ensure your bulbs and dashboard indicators are also functioning properly.

Driving at a minimum of 40 mph for 15–30 minutes on open roads can sometimes trigger automatic regeneration. Avoid short trips and low-speed driving, which prevent the filter from reaching the required temperature for cleaning.

Most Audi A5 DPFs last up to 180,000 km, but urban driving, poor oil quality, or short trips can shorten lifespan. Watch for repeated alerts, failed regenerations, or decreased fuel efficiency as signs it's time for replacement.

Tips to extend DPF life:

• Drive longer distances at highway speeds
• Use approved engine oil
• Avoid low-speed, short-distance trips
• Keep your EGR system and turbocharger in good condition
• Refill diesel exhaust fluid (if applicable)

• Use your registration or model year in our advanced search

We also provide detailed info, including the article number and fitment guide, with every listing. If unsure, our support team can help verify fitment with a few vehicle details.

You'll need:

• A standard mounting kit (gasket, clamp, hanger)
• Tools for detaching the exhaust manifold and pipework
• A scanner to reset dashboard error lights

Your local garage can complete the job in under a day, especially if combined with a gearbox service or secondary filter change. Installation time can vary based on vehicle age and corrosion level on bolts and flanges.

Alongside your new filter, check:

• Pressure sensors and EGR valves
• Cracked pipes, seals, or blocked hoses
• If needed, upgrade the catalytic converter (in cat-DPF units)
