Mercedes V-Class W447 (2014-Today) Diesel Particulate Filter DPF

The DPF in the Mercedes V-Class W447 (including models like V 200, V 220 CDI/d, V 250, V 300, EQV) is a crucial part of the diesel exhaust system. It captures fine particulate matter (soot) to comply with Euro 4, 5, or 6 emission standards. The filter is typically made from silicon carbide or cordierite ceramic materials and measures approximately 960 mm or 1260 mm in length, weighing between 6 and 8.5 kg.

If your DPF is clogged or defective, you may experience:

• Increased fuel consumption.
• Loss of engine power.
• Check Engine warning light illumination.

These symptoms indicate the DPF may need cleaning or replacement to restore performance and emission compliance.

There are several methods to clean the DPF:

• Passive regeneration: Drive continuously at 60-80 km/h for 25-30 minutes to reach the optimal temperature and burn off soot deposits (up to 60 g of ash maximum).
• Active regeneration: Use diagnostic tools such as VCDS to initiate a forced regeneration cycle.
• Chemical cleaning: Apply special aerosol or liquid additives designed for DPF cleaning (for example, 400 ml CARTECHNIC spray).

Regular cleaning helps maintain DPF performance and vehicle compliance.

It is recommended to replace the DPF every 135,000 to 175,000 km to avoid breakdowns and ensure optimal performance.

• Replacement filters comply with OBD, CE/CEE standards, and Euro 5 or Euro 6 norms.
• Common OEM references include A4474900083 and 4474903700.

Proper replacement ensures emission standards are met and engine performance is maintained.

Compatible DPFs typically feature:
