Q: What is a DPF filter in a DAF truck? 

‌DPF (Diesel Particulate Filter)‌ is a key part of a diesel engine's exhaust system. It traps and filters particulate matter (PM) to cut down on pollution. In DAF trucks, it's essential for meeting National VI and higher emission standards. It captures unburned carbon smoke and other harmful particles effectively.

The DPF is typically made from ceramic material. Its honeycomb filter structure catches particles through diffusion and inertial interception. It can clean up to 70–90% of exhaust pollutants. Over time, particles build up, raising back pressure and hurting engine performance. To keep working right, the DPF needs regular "regeneration" to burn off the trapped particles.

Regeneration happens in two ways: passive and active. Passive regeneration uses exhaust heat during normal driving. Active regeneration kicks in when the engine control unit adjusts ignition timing or injects extra fuel to raise temperatures. If too many particles build up or the wrong oil is used (like high-ash oil), regeneration can fail. When that happens, professional service or replacement is needed.

For DAF truck owners, proper DPF care is crucial. Avoid long idling or low-speed driving to let passive regeneration work smoothly. If power drops or a warning light comes on, get it checked right away. Never try forced regeneration yourself—it can be dangerous.

Q: Who makes DAF filters?

The original manufacturer of DAF filters is DAF company itself, which is a Dutch manufacturer of heavy-duty trucks and commercial vehicles. Its original filters (including air filters, fuel filters, etc.) are specifically designed for DAF models, such as CF, XF series, etc. ‌
In the field of automotive maintenance and repair, original parts are usually produced directly or authorized by vehicle manufacturers to ensure optimal matching and performance. DAF, as the brand owner, is responsible for the original supply of its filters.

Q: What are the signs of a clogged DPF filter?

When the diesel particulate filter (DPF) is clogged, vehicles usually issue warning signals through various means. Here are some common signs that combine instrument indications, performance changes, and driving experience:

• Instrument panel warning light prompt: The DPF warning light (often an icon with an exhaust filter) is a direct indicator. The constant illumination of the light usually indicates a level one alarm, that is, DPF carbon deposits have reached a certain level and require regeneration treatment; If the light flashes, it will prompt a second level alarm, indicating severe blockage, which may have triggered engine torque or speed limits to protect the system. In addition, the driver's warning light yellow constantly on may be associated with insufficient urea or system failure, while the carbon accumulation indicator light flashing or constantly on indicates the need for parking regeneration or service station intervention, respectively.

• Decreased power performance: DPF blockage will increase exhaust back pressure, hinder exhaust emissions, and lead to reduced engine power. Manifesting as weak acceleration, slow acceleration, and even difficulty shifting gears or abnormal RPM while driving at high speeds.

• Abnormal fuel consumption and emissions:

Due to poor exhaust, the engine needs to work harder, and fuel consumption may significantly increase. At the same time, the exhaust may present a heavy black smoke or be accompanied by an odor, which reflects insufficient combustion and reduced particulate matter filtration efficiency.
• Idle or abnormal start: In idle state, the engine speed may increase abnormally (such as reaching around 1000 revolutions per minute), which may be a sign that the DPF is full. When there is severe blockage, it may even make it difficult to start the vehicle, which needs to be confirmed through data flow or professional diagnosis.

• Abnormal regeneration process: DPF relies on active or passive regeneration to remove carbon deposits. If the system detects blockage, it will automatically trigger regeneration (such as passive regeneration during high-speed driving), but if regeneration fails or occurs frequently, it may be accompanied by high exhaust pipe temperature, white smoke emission, or continuous indicator light alarm.
