How much does DPF cleaning cost?

A diesel particulate filter is a must on vehicles with diesel engines. It plays a key role in limiting the emissions of pollutants your vehicle emits during your travels. This is why it is necessary to clean the DPF from time to time to prevent clogging.

🚘 What is a Diesel Particulate Filter (DPF)?

The diesel particulate filter, located on the exhaust line, is most often located after the engine outlet. Usually DPF can filter up to 99% of polluting particles... His work is presented in two separate stages:

• Particle collection : This filtration phase allows the collection of polluting emissions. Over time, particles stored in the filter will form a layer of soot, which will be less effective at retaining dirt. In addition, overloading the filter will also affect the performance of the engine, which will decrease significantly;
• Filter regeneration : The filter itself automatically cleans itself, removing soot deposits that have accumulated during collection. Due to the high engine temperature, the particles are burned and removed.

However, if the DPF is too clogged, the sensors will be there to detect it and they will transmit that data to your car's engine. In this way, the exhaust gases are heated more, particles are absorbed and started. automatic regeneration cycle filters.

💨 What does DPF cleaning consist of?

To avoid costly replacement of your vehicle's particulate filter, you can clean it. There are currently two different methods for this:

1. Use of the additive : This maneuver can be performed by you without the help of a professional. The additive will have to be poured into a container. fuel, either as a preventive measure or as a treatment measure in case the DPF is already blocked. You will then need to drive about ten kilometers, forcing your engine to climb the towers to raise the temperature of the system and allow the stored particles to be burned;
2. Descaling DPF and engine : descaling it is an operation that will work in the entire engine system. This removes any existing limescale, liquefies the passages and cleanses all parts of the engine. The injectors, exhaust gas recirculation valve, FAP and turbo look like new after descaling. Several methods of descaling are known, including hydrogen descaling, which is known to be very effective.

🗓️ When should DPF cleaning be done?

There is no specific frequency to perform DPF cleaning. It is recommended to add an additive to the fuel. once a year for preventive purposes... However, if your DPF needs to be cleaned or replaced in the most severe cases, there are several warning signs that may alert you:

• The engine is losing power : during the acceleration phases, the motor will no longer be able to keep track of the speed;
• Black smoke coming out of the tailpipe : particles are no longer removed and the filter is completely clogged;
• Excessive fuel consumption : As the engine overheats to remove particulate matter, it will consume a lot more diesel.
• Engine stalls regularly : you notice the feeling of suffocation from the engine.

If you have any of these symptoms, add the additive to the tank and move to clear the DPF. If this method is ineffective, you will have to go to the garage to deeply descale your vehicle.

💸 How much does it cost to clean the particulate filter?

If you clean your DPF yourself, you just need to buy a container of additive from an automotive supplier or online. It will cost you in between 20 € and 70 € depending on the brand.

However, if you need professional descaling, the average price will be about 100 €... The price of the service will vary depending on the type of descaling you choose and the working hours required for your vehicle.

DPF cleaning is essential to ensure good performance of your engine. It is part of your vehicle's maintenance that will allow you to extend the life of various engine and exhaust system related parts.
