Description

This listing details the diesel particulate filter (DPF) for Mercedes C220 CDI W204 models equipped with the OM651 engine, produced between 2008 and 2014 and adhering to Euro 5 emission standards. We specialise in professional cleaning services for this specific unit, identified by OEM part number A6464907192 or its common alternative BM11062.

A diesel particulate filter is an essential component within modern diesel exhaust systems, mandated to trap and remove harmful soot particles from engine exhaust gases before they are emitted into the atmosphere. This intricate device features a ceramic substrate with a honeycomb structure, which acts as a physical filter for particulate matter. Over time, these filters accumulate soot and non-combustible ash, necessitating regular regeneration cycles where trapped soot is burned off at high temperatures.

Common failure modes for this Mercedes DPF primarily involve blockages. These issues often arise from incomplete regeneration cycles, frequently triggered by prevalent short journeys, incorrect engine oil specifications leading to excessive ash build-up, or malfunctions in critical engine management components such as faulty temperature or pressure sensors, issues with the Exhaust Gas Recirculation (EGR) valve, or injector problems. A severely blocked DPF will significantly restrict exhaust gas flow, resulting in noticeable reductions in engine performance, increased fuel consumption, and the illumination of dashboard warning lights. While less common, physical damage to the ceramic substrate can also occur due to impacts or sudden thermal shock.

At Gap Turbos, we offer a comprehensive and effective cleaning service for this Mercedes C220 CDI DPF. Our process employs advanced workshop ultrasonic and thermal cleaning techniques, meticulously designed to remove both accumulated soot and non-combustible ash deposits from the filter’s intricate internal structure. This state-of-the-art method effectively restores the DPF’s flow efficiency to near-new levels, typically achieving substantial cost savings, often 70-90% cheaper than purchasing a brand-new replacement unit, provided the ceramic substrate remains intact and undamaged. It is important to note that DPF removal is illegal in the UK and will result in an automatic MOT failure.

What this diesel particulate filter (DPF) fits

This particular diesel particulate filter is specifically designed for the Mercedes-Benz C-Class W204 chassis, exclusively for the C220 CDI variant manufactured between the years 2008 and 2014. It is fully compatible with vehicles fitted with the Euro 5 compliant OM651 diesel engine. The original equipment manufacturer (OEM) part number for this unit is A6464907192, with BM11062 being a widely recognised alternative reference. We strongly advise cross-referencing these numbers with your vehicle’s existing DPF to ensure absolute correct fitment.

Specifications

Vehicle fitment

• Mercedes C220 CDI W204

Common faults & troubleshooting

• Reduced engine power or “limp home” mode: Often indicates a severely restricted DPF; a professional clean can restore exhaust flow.
• Increased fuel consumption: A blocked DPF creates back pressure, forcing the engine to work harder and consume more fuel; address the blockage promptly.
• Dashboard warning lights (DPF symbol, engine management light): These indicate a DPF fault or blockage; scan for fault codes to identify the specific issue.
• Excessive white smoke from exhaust: Can be a sign of a failed regeneration attempt or a DPF issue; investigate underlying causes like injector problems.
• Strong diesel smell or exhaust fumes in cabin: Suggests a leak in the exhaust system or a DPF that isn’t functioning correctly; inspect for cracks or loose connections.

Fitting notes for this unit

• Always replace all gaskets and sealing rings when refitting the DPF to ensure a leak-free seal and proper sensor operation.
• Ensure all pressure and temperature sensors are correctly reconnected and torqued; incorrect sensor readings can prevent regeneration.
• Check for any exhaust system leaks upstream of the DPF, as these can disrupt pressure readings and regeneration cycles.
• After fitting, perform a forced regeneration using diagnostic equipment to clear any stored fault codes and initiate the DPF’s self-cleaning process.
• Verify that the correct low-ash, C3-specification engine oil is used, as incorrect oil can accelerate ash build-up in the DPF.
• Torque the DPF mounting bolts to manufacturer specifications to prevent exhaust leaks and ensure structural integrity.
