Liqui Moly Pro-Line Diesel Particulate Filter Purge

For flushing passenger car diesel particulate filters (DPF/FAP) after cleaning with Pro-Line Diesel Particulate Filter Cleaner when installed. Flushes the soot softened by the cleaner and distributes this in the diesel particulate filter so that it can be burned off with normal regeneration. The cleaner is neutralized by the Purge. Regular cleaning in combination with flushing can help avoid expensive repairs.

For passenger car diesel engines with diesel particulate filter (DPF/FAP).

Application

Cleaning is performed with the DPF Pressurized Tank Spray Gun (part no. 7946) and the specially developed DPF Probe with 5 interchangeable tips (part no. 7945). Depending on the type of vehicle, establish access to the diesel particulate filter. On most vehicles, remove the temperature or pressure sensor of the diesel particulate filter for this. Note: The temperature of the particulate filter during cleaning should be less than 40 °C. In some vehicles the diesel particulate filter is located near the exhaust manifold or in some cases the turbocharger rather than on the underbody. For safety reasons, use extreme care when cleaning these vehicles to ensure that no cleaning or flushing fluid enters the combustion chamber via an open exhaust valve. Introduce the appropriate Pro-Line Spray Probe for the type of vehicle into the particulate filter through the opening that is created. The total amount of Pro-Line Diesel Particulate Filter Cleaner (1 l) is sprayed directly onto the surface of the particulate filter in several intervals of 5 – 10 seconds with a break of 5 – 10 seconds in each case at an operating pressure of 6 – 8 bar. In order to coat the entire surface to the greatest possible extent, turn the probe and move it back and forth when cleaning. Wait approx. 15 minutes to allow the cleaner to take effect. Then flush the particulate filter with the total amount of Pro-Line Diesel Particulate Filter Cleaner (500 ml). Processing is likewise performed with the DPF Pressurized Tank Spray Gun at the same intervals as for the cleaning fluid. The cleaning dissolves the soot enough and distributes it in the particulate filter so that it can be burned off with normal regeneration. After the sensor has been reinstalled, the service operation or the workshop must initiate a regeneration as per the manufacturer’s specifications. Attention: Refer to the safety data sheet for the protective measures to be taken when handling the product.

Other information

Attention: Following application, depressurize the pressure tank and drain it completely. The gun must not be stored with material in the tank.
