How Do You Force Clean DPF? Everything You Need to Know

DPF stands for diesel particulate filter in diesel running engines. The car engines have a tough duty to run per mile, especially if it revs on diesel fuel with hydrocarbon soot and ash deposits stuck to the filter gauze. A Particulate diesel Filter is a device installed in the engine’s exhaust systems to remove smoke. However, it is not any smoke. The gaseous compounds of burnt diesel’s mini particles and carbon toxins are inevitable. The car releases them anyhow like other fumes and warming gases. The catalytic devices or DPFs in the trucks, cars and vehicles convert the toxic fumes into eco-friendly gases to help protect the atmosphere. These do not harm the environment and cause air pollution once the contaminated smoke converts. However, once they are overfilled with soot and rubbish, they need proper DPF solutions and maintenance. 

The Symptoms and Cleaning Prices 

The car service helps in cleaning these filters professionally. However, if you clean them from your car mechanic, he will charge from €200 to €500 per year to cleanse the DPF from contaminants. Instead of heavy mechanical tools, you can simply try them at home for €60! Learn the mechanism of it first and cleanse the DPF whenever the engine idles or the following symptoms appear.

  • A strange smell rose from the revving engine. 
  • The engine ignition becomes harder to charge up
  • Loss of excessive fuel due to more strain on the engine to run. 

How Do DPF Particulates Develop? 

The DPF protects a vigorous amount of cheap diesel fuel particulates blocks completely. It is dangerous for the car engine not to be able to excrete the smoke from the silencer from the blockage. The hydrocarbon particulates collect each other in the filtrate and trigger the engine management system to lower the efficiency of cleansing itself. The continuous accumulation can weaken the engine if left uncleaned. Due to poor service history and maintenance of the vehicle and severe performance boosting tricks can also ruin the DPF and block it from time to time. The poor quality of diesel is the main cause of DPF contamination. The device pressurizes the engine to boost when the engine is already weak to run. The wear and tear of the engine compartments and continuous circulation of the burning soot and ash inside can also bust the engine. 

How To Clean DPF by DIY? 

As it can be expensive to do it alone without a complete car service, you can purchase a DPF cleaner solution for less than €60. The cleansing agents can quickly burn the hydrocarbons into plain gas and reduce the blockage. The steps are simple and efficient. All you need to do is open the temperature sensor and plug the nozzle of the cleaning agent directly into the hole. Press and keep moving the tube or bottle to fill the chamber with the cleaning fluid. Once the bottle empties, you can start the engine, wait for all the particulates to burn with the cleansing compounds, and clear out the blockage. It takes a few minutes to keep the car on rev mode and extract white smoke from the muffler to let all the liquid and carbon toxins burn in the air. You can take your car for a drive to check if the weak engine feeling wears off or not. 

Force Regeneration by Mechanics 

Taking the entire DPF out from the car can be hectic, not for your mechanic. Spraying gushing water from a pipe to cleanse out the gauzes from soot and ash can prove beneficial by clearing out all the particulates and adjusting it back to assist the engine drive smooth and sound. The cleansing agents and detergents mechanics use might be tacky for DIY methods common car owners use. They might weaken the working systems of the engine if poured in excess. Mechanics have specialized methods to force DPF soot to wash down in the drain. The squeaky clean the device back in position, and you are good to go. Some technicians regenerate a code inside the car related to the DPF in modern engines to automatically clean out the deposits from the filtrate. 

How Will I Know If my DPF Blocks?

A warning light turns on to let you know it is time to clean the diesel filtrate as soon as possible. It is unsafe to ignore the blinking light because it alerts regarding the engine power reduction and lack of fuel economy. The driver in the seat will sense the engine health poorer in throttle responses. The weakened health of the engine can lead to serious issues inside the car. 

Diesel Particulate Filter Removal 

Never go for removing the complete device from the car, as it is illegal to run your car without a DPF installed. Considered a major MOT test failure, DPF is an essential element of the car to protect the environment from blackish smoke. The black gaseous compounds can ruin the atmosphere without a DPF device installed and can bust the engine if it blocks. The engine systems are sensitive to such deposits and contaminants if left unchecked. Similarly, the ecosystem perishes with smoke and hazardous gases if the DPF is dirty. 


Maintaining a great service history is better, so all the engine essentials and compartments get cleaned with safe techniques and professional tools. The agent’s mechanics’ use is long-lasting indeed. However, to save a few euros from toppling off-budget, you should always keep a DPF cleaner in your car. 

Mechanic Tip: Answer the call of the car at one symptom. If you leave one symptom unchecked, it will also trigger other working parts to collapse. 

Consult your mechanic if the DPF light often blinks or does not fade away. Do not risk any chemical inside the engine that may worsen the situation or charge you extra for replacements. These are all the important things you need to know about DPFs and their cleansing rules.
