Audi A1 Diesel Particulate Filter DPF 1 (I) (2010-2018)

The DPF (Diesel Particulate Filter) in the Audi A1 diesel models, such as the 1.6 TDI (90 or 115 HP), is an anti-pollution device integrated into the exhaust system after the turbo and catalytic converter. It captures up to 99% of harmful diesel particulates using a porous ceramic substrate, reducing the emission of cancer-causing soot particles into the environment.

Exhaust gases pass through the filter where porous walls trap soot particles. When soot accumulates to a certain level (up to 60 g for the Audi A1 1.6 TDI), sensors trigger an automatic regeneration phase. This burns off the captured soot at high temperatures via extra fuel injection or post-combustion, restoring the filter’s efficiency.

Common symptoms include:

• Illumination of the engine or DPF warning light on the dashboard
• Loss of engine power due to blocked gas flow
• Increased fuel consumption
• Error codes such as P2463 indicating a clogged DPF or regeneration issues

DPF sensor faults are frequently reported on these models, often requiring sensor replacement to resolve regeneration problems.

DPF maintenance includes:

• Manual regeneration by driving at 60-80 km/h for 25-30 minutes to reach soot burn-off temperature or using diagnostic tools (VCDS/OBD)
• Use of diesel-compatible cleaning additives poured into the fuel tank, which help reduce soot buildup
• Decarbonisation treatments demonstrated to reduce soot quantity significantly

Cleaning is recommended every 100,000 km or if clogging occurs, preferably before considering replacement. Care should be taken to avoid affecting pressure sensors during cleaning.

The DPF typically requires replacement between 120,000 and 200,000 km or immediately upon significant malfunction. Replacement is costly, estimated between 1000 and 2000 euros (before taxes and labor). A DPF exceeding 60 g of ash content must be replaced to ensure proper exhaust and emission system function.

Krosfou offers brand-new, high-performance DPFs and catalytic converters manufactured in Europe, certified by TÜV SÜD for superior or equal quality to original parts. Made in stainless steel with high-grade ceramic monoliths using advanced coating technology, they provide excellent durability and performance.

• 3-year warranty limited to 100,000 km of use
• Compliance with European regulations and manufacturer specifications
• Free returns within 30 days for unused, original packaging products

Proper installation by a professional and adherence to maintenance guidelines ensure warranty validity.

Driving with the DPF warning light on is not recommended as it indicates issues like clogging or sensor faults affecting exhaust flow and engine performance. Prolonged driving without addressing the issue can lead to engine damage or increased emissions.

• Attempt to perform a manual regeneration by driving at steady speeds as recommended
• Have the vehicle checked with a diagnostic tool or by a professional to identify and fix the root cause

Immediate attention prevents costly repairs and further damage to the diesel particulate filter and related exhaust components.

DPF clearing (regeneration) can be initiated automatically by sensors detecting soot accumulation or manually by the driver. Manual methods include:

• Driving at sustained speeds (60-80 km/h) for 25-30 minutes to raise exhaust temperature and burn off soot
• Using professional diagnostic tools (like VCDS/OBD) to trigger forced regeneration
• Adding approved diesel fuel additives that enhance soot combustion and filter cleaning

Regular maintenance and avoiding short trips help maintain DPF efficiency and longevity.
