Clogged Particulate Filter (DPF)
By Bardahl • The 11/30/2018 • 5 min reading

The breakdown of the particulate filter or DPF is very common on a Diesel vehicle. However, cleaning and degreasing the DPF is within everyone's reach!
Depending on your driving habits, this organ will become clogged more or less quickly. If this is the case, Bardahl allows you to avoid replacing the DPF by cleaning it. With our solutions, you will avoid replacing it prematurely.
What is a DPF used for?
The DPF is a motor component that traps many very fine particles that are harmful to health. It is located on the exhaust gas line and becomes clogged more or less quickly depending on the driving mode. If it no longer works properly, you will be refused the technical inspection!
How and why does the DPF get clogged?
The DPF traps particles present in the exhaust gases and then forms a layer of soot on its walls. After a cycle (a distance traveled or a saturation level, this varies depending on the manufacturer), your DPF will increase its temperature in order to burn the accumulated soot and carbon. But very often, this does not eliminate all the carbon present in the DPF.
It is therefore in your best interest to clean it in order to avoid a breakdown.
Bardahl has several solutions for cleaning your DPF, both preventively and curatively!
Why clean your DPF?
The reason is simple: maintenance is essential to increase the life of your vehicle and avoid replacement (and therefore unnecessary costs). But that's not all!
Cleaning your DPF with Bardahl products:
- Lowers the combustion temperature of soot particles
- Prevents fouling due to the accumulation of unburned soot
- Does not alter the components (precious metals) allowing to sting and burn harmful particles
- Avoids overconsumption, loss of power and replacement of the particle filter. In the event of a blocked filter, the exhaust gases can no longer escape and the engine stalls due to suffocation
- Allows soot retained inside the filter to be burned and destroyed more easily
- Extends the life and proper functioning of particulate filters
- Allows you to pass your technical inspection without the risk of being refused
How do I know if my DPF needs cleaning?
Prevention is always better than cure. With preventive use of our additives, you will avoid problems with clogged DPF. If you have not yet had this reflex, there are many symptoms that can alert you before a breakdown. This is never serious at first, but the consequences can be expensive in repairs if you do not react:
- Power loss without big smokes
- Orange or red engine / DPF warning light
- Vehicle in "safety" mode
- The engine chokes, cuts out or stalls too easily
How to clean and maintain your DPF?
The estimated cost of replacing a DPF varies from €1,500 to €4,000 depending on the model. In order to avoid the costs associated with replacing your DPF, there are 2 solutions:
1. A bottle to pour into your fuel tank
Our additives are easy to use, just add them to your tank either as a preventative or curative measure.
- If you drive in the city or only make short trips, clean every 5000 km or once a year with Bardahl DPF cleaner.
- You regularly drive on the motorway: clean every 10,000 km or once a year with Bardahl FAP cleaner
- Consider driving in a lower gear from time to time. For example, you drive at 120 km/h in 5th gear, instead of 6th, for a period of 15 minutes.
2. FAP and engine decarbonization
The most efficient and innovative process on the market for cleaning your DPF is Bardahl’s eco-engine cleaning!
With the largest network of professionals in the world in this field, our 3,000 experts will decarbonize your engine to give it a new lease of life!
Where other hydrogen decarbonization methods attempt to clean all the organs of your engine by injecting a solution only into the intake, Bardahl treats each element independently for an optimal result!
Your injectors, intake, EGR valve, turbo and FAP are cleaned between 30 minutes and 2 hours.
Concrete and immediate results
- A reduction in your consumption and therefore an increase in autonomy.
- A reduction in the opacity of exhaust fumes and therefore a reduction in harmful emissions.
- A smoother, more dynamic ride.
- A return to original power and responsiveness.
