What is a DPF Filter?
Diesel engines are powered by compression-ignition combustion, which produces a sooty byproduct in contrast to gasoline engines. If these invisible soot particles escape the car as untreated exhaust fumes, they could seriously harm human health and the environment. An older diesel vehicle’s signature smokey, black exhaust gases are a dead giveaway that a diesel particulate filter is at work, trapping this soot and any hazardous particles to keep them from being released into the sky.
Is Your Diesel Motor in Limp Mode? We'll fix it
DPF Issues often cause vehicles to go into forced Limp Home Mode. Designed to prevent further damage to the system.
This Can sometime’s be dangerous particularly on Motor Ways. Get Your DPF issue Sorted Immediately.
How do DPF Filters Work
The inside of a DPF is typically constructed of a silicon carbide honeycomb with a high porosity. The porous walls of this catalytic honeycomb structure catch solid hazardous particles when unfiltered diesel exhaust fumes pass through the channels of the DPF, while still allowing the filtered gaseous components of the exhaust to escape as vapour.
While the vast majority of dangerous particles are kept from entering the atmosphere thanks to this mechanism, the soot itself builds up inside the filter as a “cake” layer. When the diesel particulate filter is full, an excess of this cake layer might result in blockages, which may result in breakdowns.
Your DPF must be kept as clean as possible to avoid a blockage from happening. To do this, extra soot that has built up inside the filter must be burned at a temperature high enough to transform it into finer ash particles that can be ejected from the system. The term “regeneration” refers to this self-cleaning process. Exhaust system issues may arise if this procedure is halted and the DPF is unable to renew.
Watch for these DPF warning signs:
- Increased fuel consumption
- Excessive black smoke
- Strong diesel smell
- Loss of engine power
- Stop-start system failure

Frequently Asked questions
A DPF (Diesel Particulate Filter) is a component in diesel vehicles designed to trap harmful soot particles before they are released into the atmosphere. It helps reduce air pollution.
The DPF has a honeycomb structure that captures soot particles. This soot builds up over time and needs to be burned off in a process called regeneration.
Signs of a blocked DPF include reduced engine power, increased fuel consumption, excessive smoke, and the engine going into limp mode.
DPF regeneration is a process where the soot trapped in the filter is burned off at high temperatures. This can occur passively during normal driving or actively through forced regeneration.
While some additives and cleaning solutions claim to clean DPF filters, it's generally recommended to leave this task to professionals due to the complexity of the process.
The frequency of DPF cleaning or replacement depends on driving conditions, fuel quality, and vehicle maintenance. Regular servicing and adhering to recommended maintenance schedules can help prolong the life of your DPF.
Removing a DPF filter is illegal in most countries as it is a crucial component for emissions control. It's essential to maintain a properly functioning DPF to comply with environmental regulations.
Urban Autohaus offers DPF diagnosis, cleaning, and replacement services. Our experts can identify the root cause of DPF problems and provide effective solutions to restore your vehicle's performance.
