Description

This listing is for a Volkswagen Golf 2.0 TDI Euro 4 Diesel Particulate Filter (DPF), suitable for BKD and AZV engine codes from 2003-2009. We offer professional cleaning services for this specific DPF, providing a cost-effective alternative to full replacement.

A DPF is an exhaust aftertreatment device designed to trap soot particles from diesel engine exhaust gases. It works by collecting these particles, which are then periodically burned off during regeneration cycles, preventing their release into the atmosphere. This component is crucial for meeting Euro 4 emissions standards and is a mandatory fitment in the UK, ensuring environmental compliance and vehicle legality.

What this diesel particulate filter (DPF) fits

This DPF is specifically engineered for the Volkswagen Golf 2.0 TDI model range, manufactured between 2003 and 2009. It is compatible with vehicles equipped with the BKD and AZV engine codes, which are common in this generation of Golf. The original equipment (OE) part number for this unit is BM11055, with an alternative part number 1K0254705LX also applicable. It ensures the vehicle complies with Euro 4 emissions regulations.

Over time, DPFs can become blocked with excessive soot and ash, especially if the vehicle primarily undertakes short journeys or if the regeneration process is incomplete. Common causes include faulty injectors, EGR valve issues, turbocharger problems leading to oil consumption, or incorrect engine oil usage. A heavily blocked DPF will restrict exhaust gas flow, leading to reduced engine performance, increased fuel consumption, and dashboard warning lights. In severe cases, the DPF substrate can melt or crack due to excessive heat from attempted regenerations on a fully blocked unit. DPF removal is illegal in the UK and will result in an MOT failure.

At Gap Turbos, we specialise in DPF cleaning services. For this VW Golf 2.0 TDI DPF, we offer a comprehensive workshop ultrasonic and thermal cleaning process. This method effectively removes accumulated soot and ash from the DPF substrate, restoring its flow characteristics to near-new condition, provided the internal ceramic matrix is intact. Cleaning is a highly cost-effective solution, typically 70-90% cheaper than purchasing a new replacement DPF. We also offer advice on mobile cleaning or forced regeneration if appropriate for less severe blockages.

Common faults & troubleshooting

[‘Reduced engine power and limp mode: Indicates a severely blocked DPF restricting exhaust flow; requires DPF cleaning or replacement.’, ‘DPF warning light illuminated on dashboard: Suggests a DPF blockage or regeneration issue; attempt a forced regeneration or seek professional diagnosis.’, ‘Increased fuel consumption: A DPF struggling to regenerate can lead to the engine injecting more fuel to attempt regeneration, increasing consumption.’, ‘Excessive white smoke from exhaust: May indicate unburnt fuel entering the exhaust during failed regeneration attempts, often linked to DPF issues.’, ‘Strong diesel smell: Can be a sign of DPF regeneration issues, where fuel is not completely burnt off in the exhaust system.’, ‘Engine oil level rising: Diesel fuel can dilute engine oil if regeneration attempts are frequent and incomplete; requires immediate attention and oil change.’]

Fitting notes for this unit

[‘Always replace the DPF mounting gaskets and clamps to ensure a leak-free seal and proper exhaust system integrity.’, ‘Ensure all temperature and pressure sensors connected to the DPF are carefully removed and reinstalled, checking for damage or corrosion.’, ‘Verify the correct functioning of the differential pressure sensor and its associated pipes, as these are critical for DPF monitoring and regeneration.’, ‘After installation, perform a diagnostic scan to clear any DPF-related fault codes and initiate a forced regeneration if necessary, to “bed in” the cleaned unit.’, ‘Check for any underlying engine faults (e.g., injectors, EGR valve, turbocharger) that may have caused the original DPF blockage, and rectify them to prevent recurrence.’, ‘Use only C3 specification low-ash engine oil, as specified by Volkswagen, to minimise ash accumulation in the DPF and prolong its lifespan.’]
