As well as Terraclean, James Price’s Garage also offers a DPF clean suitable for vehicles with a DPF blocked with oil or ash. DPF’s block due to other problems, cleaning is not enough, you need the problem professionally identified and rectified, if not done correctly the unit will simply block again after cleaning.


What is a DPF?
A diesel particulate filter (DPF) is a device which sits within a vehicle’s exhaust system and is designed to “capture” soot/diesel particles to reduce harmful emissions into our towns and cities.
It became legal for vehicle manufacturers to fit DPFs to all vehicles when “Euro 5” emissions standards came into force in 2009, although some VMs did fit them prior to 2009.
DPFs are intended to self-clean, through a process called “regeneration”. This happens under certain driving conditions and the particles are emitted, leaving only a small ash residue. Sensors in the DPF unit communicate with the vehicle’s central computer (ECU) to determine when to clean/regenerate the DPF.
Stage One - Diagnostics
We diagnose the condition of the Diesel Particulate Filter & establish if it's blocked. Then we have to establish the cause because cleaning alone usually doesn't resolve the problem, if the cause isn't identified then it is likely to block again very soon.
Stage Two - Cleaning
The cleaning process involves injecting Specialist TerraClean fluid directly into the Diesel Particulate Filter. This process will break down the carbon particles enough to be able to pass through the filter and reduce the exhaust back pressure. The engines management will then allow a regeneration again.
Stage Three - Regeneration
The cleaning process involves injecting Specialist TerraClean fluid directly into the Diesel Particulate Filter. This process will break down the carbon particles enough to be able to pass through the filter and reduce the exhaust back pressure. The engines management will then allow a regeneration again.
