The Zetti diagnostic tool can perform static regenerations as well as diagnose DPF faults. This hand held DPF Tool simply plugs into the vehicles diagnostic connector and can be used to diagnose codes, carry out the all important forced regeneration and even zero the DPF after replacement.

Covering major manufacturers and more:
Modern diesel vehicles are fitted with complex anti-pollution systems. These systems require servicing and resetting which can only be completed via diagnostics. The Zetti DPF tool allows you to carry out numerous functions on the Diesel Particulate Filter system without having to send the car to a main dealer. The tool will reset the DPF light after the filter has been replaced, reset the additive level after it has been topped up, and burn off collected particles when a maximum fill level is reached by performing a static regeneration. It is only necessary to replace the DPF when this process breaks down and the filter becomes irreversibly clogged. The Zetti DPF reset tool covers the majority of our range of Diesel Particulate Filters.
*It is only necessary to replace the DPF when the filter becomes irreversibly blocked.
The DPF Regeneration Process
Dependent on the vehicle a DPF may either need to be regenerated by one of the following methods:
The DPF is constantly cleaned through a catalyst process when the vehicle is driven at a certain speed or length of time.
When the DPF reaches a predetermined level (usually 45% capacity) the ECU will make small adjustments to the fuel injection timing system to increase exhaust temperature to initiate the regeneration process. In order to reach this temperature the vehicle must be driven for a certain time period at a minimum speed. If frequent stop start driving takes place the opportunity does not exist for the vehicle to regenerate the DPF. In this case a warning light will illuminate on the dash to advise the DPF is partially full. The vehicle will need to be taken for a long drive to regenerate the DPF. If the DPF becomes to full to perform a regeneration on its own the DPF will have to undergo a “static” regeneration with the use of specialized diagnostic equipment. When a DPF becomes 90% it is no longer able to be regenerated and will have to be replaced.
Active Regeneration with additives:
As per Active Regeneration but with the aid of an additive (EOLYS™) which is injected into the exhaust to lower the temperature required to perform the regeneration. Most commonly found in Peugeot and Citroën vehicles.
Regeneration will not take place when:
– The fuel light is on, or there is less than 20 litres of fuel in the tank.
– The ‘check engine’ light is on.
– Your foot is resting on the clutch pedal.
– DPF failure can be due to:
– Poor engine maintenance
– Malfunctioning pressure sensor/pipes (condensation in the pipes)
– Faulty temperature sensors
– Incorrect oil temperature
– Faulty EGR valve
– Damaged exhaust system
– Incorrect fuel
– Short runs (lack of temperature)
