Stop-start driving conditions reduce the engines ability to make the necessary adjustments to induce regeneration of the DPF (Diesel Particulate Filter), causing a continual build of soot and carbon in the filter.

Left unchecked this will eventually lead to an engine fault and the vehicle will go into limp mode.

Tec4 Post-Combustion DPF Soak along with Tec4 Post-Combustion DPF Flush are technically advanced formulations for application via Tec4 Carbon Cleaning Equipment, designed to effectively clean the DPF on-board – so there’s no need to remove the DPF from the vehicle.

Key Benefits:

• Cleans soot, carbon and ash from the DPF
• Improves engine performance and response
• Reduces harmful exhaust emissions
• Improves fuel economy
• Compatible with all DPF types
• Will not harm catalytic converter.

APPLICATION – DO NOT MIX WITH FUEL :

(For full application instructions please refer to the Carbon Cleaning machine instruction manual.)

Post-Combustion DPF SOAK and FLUSH should only be administered using the Tec4 Carbon Cleaning Machine.

The products are simply injected into the exhaust system at a suitable location prior to the DPF, (typically this is done via the oxygen sensor plug) with the engine running at approximately 2000rpm.

These products will dissolve soot, carbon and ash from the DPF allowing it to be safely discharged through the exhaust outlet.

Care should be taken to ensure the cleaning operation is conducted in a well-ventilated area away from residential buildings.

Tec4 accepts no responsibility for any damage caused to the engine during the cleaning process due to over-loading of the system with product or solid matter entering the combustion chamber.
