Forté Diesel Particulate Filter Cleaner and Regenerator has been specifically formulated to combat the adverse effects that start/stop driving conditions have on Diesel Particulate Filter (DPF) regeneration. With a continued stop/start driving pattern, soot loading builds up in the DPF since the ECU is unable to make the necessary small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration.

Forté DPF Cleaner and Regenerator uses a catalyst to adhere to the soot particles during combustion, lowering the temperature at which they can be burnt off. The soot particles will burn at lower temperatures in the soot filter area, helping to regenerate the filter, especially in cases where exhaust temperatures are low, like stop and go traffic, city traffic and short drives.

Forté DPF Cleaner and Regenerator should be used at regular service intervals in conjunction with Forté Advanced Formula Diesel Treatment and when the symptoms indicate that treatment is necessary.

  • Aids passive regeneration of Diesel Particulate Filter
  • Actively reduces soot emissions
  • Improves stability of Diesel Particulate Filter systems
  • Compatible with all diesel engines
  • For diesel and bio diesel up to B30


Forté DPF Cleaner & Regenerator should be used at regular service intervals, use two bottles if running in limp mode and apply to the fuel tank ONLY. It is also recommended to be used in conjunction with Forté Advanced Formula Diesel Treatment and Forté Diesel Turbo Cleaner to clean & lubricate the fuel system or when the symptoms indicate that treatment is necessary to ensure efficient Diesel Particulate Filter operation.

Forté products are developed for professional trade use only.

Product Reviews for Forte DPF Cleaner & Regenerator (400ml)

Questions & Answers for Forte DPF Cleaner & Regenerator (400ml)

How do you use Forte DPF Cleaner?
Use only as directed in compression ignition engines in conjunction with the Forte Diesel Advanced Formula Fuel Treatment. Add one 400ml bottle during service intervals to the diesel fuel tank to help prevent DPF problems. One bottle treats up to 50 Litres of diesel fuel. Where a fault has occurred add two 400ml bottles to the fuel tank.

Can Forte DPF Cleaner be used if running in limp mode?
Yes, you can use it in limp mode. It is recommend 2 cans at the same time in a low tank and within 15/20 miles the light should go out.

What does a diesel particulate filter do?
The DPF is fitted within the exhaust system and is designed to catch soot particles and nitrous oxide (NOx) from the combustion process that would otherwise be released into the atmosphere. The DPF is highly effective and traps around 80 per cent of these harmful particulates.

Why do modern diesel engines need a particulate filter?
European legislation places increasingly strict exhaust emissions targets on all vehicle manufacturers. From September 2009, the ‘Euro 5′ legislative standard came into effect, part of which required all diesel cars registered from that point on to be equipped with a diesel particulate filter, or DPF.

These filters are used throughout the industry in all diesel-powered passenger vehicles, and the efficiency of this system is becoming increasingly important now that tougher ‘Euro 6′ emissions standards came into effect in September 2014.

Do I need to replace a diesel particulate filter during normal servicing?
Diesel particulate filters do have a capacity limit and can become full. But unlike traditional air, oil or pollen filters that need to be exchanged manually at regular intervals, the DPF has a much longer service life and is designed to be regenerated to restore its performance. The car’s electronic control unit (ECU) is programmed to do this automatically, neutralising the soot by burning it off at high temperature within the exhaust system while the vehicle is running. All modern cars with diesel engines follow this procedure.

How does this regeneration occur?
The regeneration occurs automatically, usually without the driver being aware that it is taking place. In the majority of cases, the process is carried out when the engine and exhaust system is up to normal operating temperature and the vehicle is travelling at over 40mph.

However, if your driving is limited to inside the city, the low speeds and frequent stops mean the conditions for normal regeneration do not exist. In these instances, the ECU monitors the accumulation of soot and instructs an alternative regeneration programme to begin well before the filter becomes saturated.

This programme injects small quantities of fuel into the engine after combustion, thereby increasing the temperature within the exhaust system and creating an environment where it is possible to safely burn off the soot.

This latter method is very successful within the small percentage of vehicles where normal regeneration is not possible. However, due to the nature of city traffic, the regeneration process can be interrupted when the vehicle completes its short journey and is turned off. If this occurs, the ECU is programmed to recommence the process when the engine is restarted and back up to temperature again.

How can I ensure that the DPF regeneration process completes successfully?
By creating frequent opportunities for the ECU to complete its normal regeneration programme. Quite simply, this means regularly driving the car at a sustained speed above 40mph for a period of at least ten minutes.

Will I be warned if all DPF regeneration processes have been unsuccessful?
Very occasionally, use of the vehicle might be such that it will have been impossible for the ECU to complete the administration of any regeneration procedure. At this point, the DPF will have become overloaded and stopped functioning, so the vehicle will illuminate a warning light in the dashboard. It will then be necessary for the soot to be neutralised and the filter regenerated manually at a main dealer.

It is extremely unwise to ignore this visual warning as the DPF can become irreparably damaged. What’s more, it is illegal to remove the filter entirely.

Why diesel particulate filters are fitted to modern cars if they bringing so much troubles?
Car manufacturers had to equip modern diesel engine cars with DPF diesel particulate filter to meet EURO 5 and EURO 6 emission criteria. This solution doesn't make our lives with modern day diesel engines easy. Very often the vehicles own DPF regeneration which avoids filter blockage is causing poor fuel consumption. In the worst scenarios - expensive DPF filter replacement.

Why is my Diesel Particulate Filter (DPNR) getting blocked so often?
Due to urban driving style DPNR commonly known as a Toyota DPF diesel particulate filter is getting blocked. There is no enough time to perform DPF regeneration in start - stop driving cycles. Toyota’s DPF system equipped with 5th injector in the manifold for quicker and better raising the temperature in the DPF filter. Even this maintenance free technology is still struggling to perform successful dpf filter regeneration.

• Short distance driving
• Poor fuel quality
• Carbon build up in the inlet manifold
• Poor servicing

All of these factors they only help get Toyota DPF filter problems. Lack of successful DPF regeneration causing complete DPF filter blockage.

Most common symptoms indicating DPF filter problems;

• Engine management & other warning lights on the dash
• Lack of power
• Poor fuel consumption
• White exhaust smoke

These symptoms should indicate your DPF filter is in trouble and needs attention.

What are the common diagnostics fault codes for DPF's?
P2002 - "DPF filter efficiency low fault code logged in".
P2453 - "Diesel particulate filter differential pressure sensor circuit range/ performance".
P2458 - "Diesel particulate filter regeneration duration".

These are the most common fault codes found on the ECU (engine control unit).
