Description
This product listing covers the diesel particulate filter (DPF) for the Mercedes C220 CDI W204, specifically models equipped with the OM651 engine from 2008 to 2014, adhering to Euro 5 emissions standards. The DPF is a critical component in your vehicle’s exhaust system, designed to capture and store diesel particulate matter (soot) from the exhaust gas, preventing its release into the atmosphere and ensuring compliance with stringent environmental regulations.
Over time, DPFs can become blocked or saturated with soot and ash, particularly if the vehicle is primarily used for short journeys, which prevents the DPF from reaching the necessary temperatures for passive regeneration. Other common failure modes include frequent incomplete active regeneration cycles, often triggered by sensor malfunctions or driving patterns. Underlying engine issues such as faulty fuel injectors leading to rich mixtures, a malfunctioning Exhaust Gas Recirculation (EGR) valve causing excessive soot production, or turbocharger oil leaks introducing unburnt oil into the exhaust stream can significantly accelerate DPF clogging. Common symptoms of a failing DPF include reduced engine performance, noticeable loss of power, increased fuel consumption, the DPF warning light illuminating on the dashboard, and ultimately, the vehicle entering ‘limp home’ mode to prevent further damage. Ignoring these warnings can lead to severe back pressure, potentially damaging the turbocharger, exhaust manifold, and other engine components.
What this diesel particulate filter (DPF) fits
This particular DPF is a direct fit for:
- Vehicle: Mercedes C220 CDI W204
- Engine Code(s): OM651
- Year Range: 2008-2014
- Euro Class: Euro 5
- OEM Part Number: BM11062
- Alternative Part Number(s): A6464907192
At Gap Turbos, we specialise in DPF cleaning services for this Mercedes unit. We offer comprehensive solutions including workshop ultrasonic and thermal cleaning, which is a highly effective method to restore DPF function by thoroughly removing accumulated soot and non-combustible ash. For certain situations, we can also provide mobile cleaning services or assist with forced regeneration procedures using diagnostic equipment. It’s important to note that DPF cleaning, provided the ceramic substrate within the filter is intact and undamaged, is typically 70-90% more cost-effective than full DPF replacement. We strictly adhere to UK regulations; DPF removal is illegal, environmentally damaging, and will result in an automatic MOT failure, carrying significant penalties.
Our experienced technicians ensure a thorough and professional service to bring your DPF back to optimal performance and compliance. For a precise quote tailored to your specific needs and details on our comprehensive warranty, please contact us directly. We are committed to providing reliable, expert service from our Birmingham facility, ensuring your Mercedes C220 CDI operates efficiently and cleanly.

Common faults & troubleshooting
- DPF warning light on dashboard: Indicates the DPF is blocked and requires regeneration or cleaning.
- Reduced engine power or ‘limp home’ mode: The engine control unit (ECU) restricts power to prevent DPF damage due to excessive back pressure.
- Increased fuel consumption: A blocked DPF can lead to more frequent and prolonged regeneration cycles, consuming extra fuel.
- Excessive white smoke from exhaust: May indicate the DPF is attempting a regeneration cycle but failing, or unburnt fuel is entering the exhaust.
- Unusual smell (e.g., burning rubber): Can be a symptom of an overheated DPF during a failed regeneration attempt.
- Engine misfires or rough running: A severely blocked DPF can create back pressure affecting exhaust gas flow and engine performance.
Fitting notes for this unit
- Always replace the DPF mounting gaskets and exhaust clamps to ensure a leak-free seal.
- Check and clean all associated DPF sensors (differential pressure sensor, temperature sensors) and their wiring during removal and refitting.
- Ensure the exhaust system is properly supported during removal and installation to prevent stress on other components.
- After fitting, perform a diagnostic scan to clear any DPF-related fault codes and initiate a forced regeneration if necessary, or ensure a full drive cycle is completed.
- Verify the engine oil level and quality; excessive oil consumption or incorrect oil type can prematurely block a DPF.
- Torque all DPF and exhaust mounting bolts to the manufacturer’s specifications to prevent leaks or damage.

Need this DPF cleaned?
Most blocked DPFs do not need replacing. Our 5-stage workshop clean restores factory flow at a fraction of the cost of a new filter, and mobile DPF cleaning is available UK-wide for fleets.
