A highly effective fluid used for cleaning soot clogged DPF units without disassembly. Dissolves contaminants inside DPF units, restores vehicle performance and fuel consumption. Regular use help prevent expensive repairs. Always use in combination with Pro-Line Diesel Particulate Filter Cleaner (part no. 20110). To apply use DPF Pressurized Tank Spray Gun (part no.7946), DPF-Probe with 5 interchangeable tips (part no. 7945) and if needed DPF Spray Probe long (part no.

For cleaning of diesel particle filter (DPF) as installed on vehicle. For professional repair shop use only.


To clean use DPF Pressurized Tank Spray Gun (part no. 7946) together with DPF-Probe with 5 Interchangeable Tips (part no. 7945). When cleaning large diameter units also use DPF Spray Probe Long (part no. 20630). Cleaning is done by removing a temperature or other sensor from the DPF unit. Observe: Before use make sure to have already used Diesel Particulate Cleaner (20110) and that DPF temperature is below 40 °C (104 °F). Particle filter location need to be determined as some vehicles have their DPF located near exhaust manifolds or next to a turbocharger. In such a case utmost care must be taken to prevent fluid from entering the combustion chamber and cause damage. Remove appropriate sensor to determine which probe (part of 7945) to use, then insert probe through sensor hole. Add full bottle of Pro-Line Purge (20112) into spray gun (7946). Set pressure at 6-8bar and spray short bursts of approximately 5-10 seconds towards core of unit while aiming up-down / side-to-side. During the cleaning process particulate deposits are dissolved and distributed inside the diesel particle filter, to allow burn off. To complete the cleaning process, activation and completion of regeneration with a Scantool or diagnostic software is needed.
