DPF Regeneration

What Is A DPF
Regeneration?

DPF regeneration is the DPF cleaning process, which is designed to remove carbon build up from the filter elements inside the diesel particulate filter itself, when it becomes partially blocked.

DPF regeneration is automatically initiated by the vehicles ECU (engine management system) as part of the normal operation of your diesel engine.

Sensors measure pressure differential between the entrance and exit of the filter (which is part of the exhaust system), and when carbon builds up inside the DPF filter and creates sufficient back pressure, the DPF regeneration process is activated to burn off the carbon build up.

This DPF regeneration cleaning process is normally achieved by injecting additional diesel into the diesel particulate filter, which generates a high temperature inside the DPF filter.

You Can Benefit From A TerraClean If Your Engine Has:

Done More Than 12k Miles

Carbon build up starts to occur around this time. Using the TerraClean service will act as preventative maintenance.

Dropped In Power & MPG

Carbon deposit may be hindering your vehicles overall performance. Removing the deposits will restore your power.

Failed An M.O.T On Emissions

TerraClean helps to reduce the emissions that your vehicle omits. By using the service you can safely pass your MOT.

How Does A DPF Regeneration Happen?

In order for this DPF cleaning regeneration to take place, certain conditions have to be met, such as engine temperature, speed and distance/time. 

Details of these will be found in your vehicle’s handbook, or you can find out by contacting the dealer or by searching on the internet for your make/model/engine.

The DPF regeneration process will usually take place during your normal driving, but other times you may see a light on the dashboard indicating DPF cleaning is required. 

This usually means you need to take your vehicle on a run for 10-15 miles at a reasonable speed (usually 50 mph+), but consult your handbook or main dealer for specific details.

Sometimes a DPF regeneration is not enough for effective DPF cleaning, and specialist cleaning processes will need to be carried out to unblock it.

After the clean it’s been 550-700 miles of range. The best mpg l got on my trip to work was 24mpg and that was coasting A LOT. Doing the same drive now I got 30mpg

To be honest, I thought I would only see a small change in performance. I am however nicely surprised how much greater it in fact is. The car now has so much more grunt and is running so much smoother.

Great customer service from reception to the technicians. I've had my E350 Terraclean and remapped the same time. The car feel's a lot more responsive and smoother throughout the automatic gear changes with plenty of torque to hand for overtaking. Great work and highly recommended.

Had Terraclean service and remap done to my Golf TDI. The car is very much more responsive than before, but haven't done enough miles yet to work our the mpg. The service received was first class and would recommend them to anyone requiring similar work to their vehicle.

…I had to take this opportunity to say how impressed I am with the results. I have noticed an average increase of 6mpg on my normal 100 mile commute, the car is much more responsive and it smokes a little less on first start in the morning. It genuinely feels like it has had 60k knocked off the clock!
