We Can Do Diesel Particulate Filter

(DPF) Regeneration For £235+vat
With A Very High Success Rate

What is Particulate Regeneration I hear you ask............

Well, its a process of where we insert a special chemical into your DPF and run your car (with the aid of our AUTOLOGIC diagnostic computer) for several miles, bringing your car up to operating tempreture, Monitoring and adjusting your car while the regeneration is in process with AUTOLOGIC, we can engage the regen process if it will not do it manually, So all this combined gives us an over 85% success rate on current modles.

Diesel Particulate filters


DPFs can reduce diesel soot
emissions by upto 80%
The exhaust emissions standards for new cars have required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to keep these systems working properly.

How do they work?
Diesel Particulate filters (DPF) catch bits of soot in the exhaust.

As with any filter they have to be emptied regularly to maintain performance. For a DPF this process is called 'REGENERATION' – the collected soot is burnt off at high temperature to leave only a tiny ash residue.


Regeneration is either passive or active

Passive regeneration takes place automatically on motorway runs when the exhaust is at high temperature . Because many cars don't get this sort of use most DPF filters block up alot earlier than normal.

Active regeneration
When the soot level in the filter reaches a set limit (around 45%) the ECU will inject more fuel to increase the exhaust temperature and activate regeneration. If the journey is short or in traffic or you take your foot off the accelerator while regeneration is in progress, it may not complete the process and the warning light may still come on to show that the filter is partially blocked.


It should be possible to start a complete regeneration and clear the warning light by driving for 15-20 minutes or so at speeds greater than 60mph.
If you ignore the warning light and keep driving in a short/traffic pattern, soot will continue to build up until around 75% then you can expect to see other warning lights come on too. After this point driving at speed alone will not be enough and you will have to take the car to a garage for regeneration or replacment.

Expensive repairs

If you continue to ignore warnings and soot keeps increasing, then the car will not run properly and more than likely you will to need to get a new DPF costing at least £1000.

The residue which remains after completed regeneration cannot be removed and will fill the filter. DPFs are designed to last about 75,000 miles but operating correctly, we see many cars achieving more than this.

The most commonly fitted type of DPF has an integrated catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that regeneration is more likely to be completed.

A wide range of manufacturers use a different type of DPF which relies on a fuel additive to lower the temperature of the soot particles to help burn easier.
The additive is placed into the fuel tank along with the fuel to make its way around to the exhaust systerm.

Don't be tempted to ignore a warning light showing that the additive tanks need refilling. It's absolutely essential this tank is refilled as without it regeneration is unlikely to be successful and a new DPF may be needed – at significant cost. Fuel consumption can increase as a result of failed regenerations too.

On some cars sixth gear may be to low in rev's and may be too low to generate the exhaust temperature needed for regeneration. sometimes driving in lower gears for longer should be sufficient to burn off the soot in some cases.
DPF regeneration shouldbe initiated by the ECU approximately every 300-400 miles depending on vehicle use and will take 10 to 15 minutes to be completed. You shouldn't notice any unusual driving conditions other than perhaps a puff of smoke from the exhaust.

Check the handbook

If you buy a car with a DPF it’s important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.

In most cases there is only a relatively short time between the dpf being partially blocked and becoming so blocked that it requires manual regeneration.
