PARTICLE FILTER ADDITIVE TOO LOVE: SYMPTOM SOLUTIONS

When a warning message indicates that the Additive level for the particles filter (FAP) It is too low, it is essential to react quickly. This additive, often called «Eolys» in the vehicles of the PSA group (Peugeot, Citroën), is essential for the correct functioning of the FAP. Find out here for this level of additives it goes down, how to identify the symptoms of a lack and what are the solutions to maintain a healthy Fap.

What is the additive of the particles filter?

The particle filter (FAP) is designed to retain and burn soil particles from the combustion of the diesel engine. In order to facilitate regeneration (i.e. the combustion of these particles), some car manufacturers use a specific additive stored in a dedicated tank.

• Role of the : Lower the combustion temperature of the particles, allowing a more common and complete cleaning of the FAP.
• Composition : Generally based on the Cerine (Cerio oxide), the additive is mixed with fuel to optimize post-cancellation.
• Use : Each time, a low volume of additives is automatically injected. When the additive tank empties, the car reports to Too low FAP additive level.

Why is the FAP additive level so important?

1. Prevention clogged : Without additive, the temperature required to burn the particles in the FAP is higher, which increases the risk of premature clog.
2. Engine performance : A dirty Fap causes loss of power and excessive fuel consumption.
3. Additional expenses : An clogged fap can request a depth cleaning or an expensive replacement if the problem persists.

Clearly, an insufficient additive level can quickly cause more serious damage to the vehicle, therefore the importance of monitoring and maintaining this tank.

Symptoms of a too low FAP additive level

Several signals indicate that it is time to control and create additives for the FAP:

1. Witness or alert message : On the dashboard, a «FAP» light or a message explicitly connected to the Additive level for particles filter It may appear.
2. Loss of power : The engine can give the impression of «force» and the guide becomes less fluid.
3. Fuel consumption : A fap that does not regenerate correctly requires the engine to request more energy.
4. Unusual odors : In case of advanced clogging, you can manifest burnt gases or stronger unloading.

What if the fap additive level was too low?

1. Add the additive :
   • Professional intervention : In general, it is recommended to induce additive recharge to a mechanic equipped with the diagnostic tool. The additive tank, often positioned near the fuel tank or under the car, requires precise handling.
   • Restores the calculator to zero : After completing the level, the engine computer must be reprogrammed to take into account the quantity of addition.
2. Check the conditions of the FAP :
   • In case of advanced clogging, cleaning of a seminar ora regeneration It may be necessary.
   • If the FAP is damaged, it will be necessary to consider its replacement.
3. Keep the vehicle regularly :
   • Use quality fuel : The particles formed are less abundant and less harmful for the FAP.
   • Respect the review intervals : Regular oil changes and periodic additive levels are in the maintenance book.
   • Adopt a suitable guide : Alternative urban trips and higher engine speed trips promote FAP’s regeneration.

What are the costs relating to the FAP subsidiary?

• Additional top -up : The price varies according to the type of additive and the required quantity, generally between € 70 and 200 € (excluding work).
• Workshop Workforce : The intervention, which includes the restoration of the calculator, can cost between € 50 and 150 €.
• FAP replacement : If the filter is irreparably damaged, it takes several hundred euros or even more than € 1,000 for an original model.

The importance of the additive particle filter

AND Additive level for particles filter too low it must not be taken slightly. This additive plays a crucial role in FAP’s regeneration, thus guaranteeing the correct functioning of the diesel engine and compliance with anti-impelution standards. In the event of a warning, it is essential to quickly recharge the additives and check the general conditions of the FAP to avoid expensive degrades. To optimize the duration of the life of the particles filter, do not forget to adopt adequate guide and scrupulously respect the maintenance calendar recommended by the manufacturer.
