LIQUI MOLY Pro-Line Diesel Particulate Filter Purge 500mL – Effective DPF Cleaning Solution for Automotive Use

Ahighly effective fluid for cleaning soot clogged DPF units without removal. Dissolves contaminants inside DPFs, restores vehicle performance and fuel consumption. Regular servicing of dpf units can help avoid expensive repair costs. Use only together with Pro-Line Diesel Particulate Filter Cleaner (part no. 20110), to apply use only 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. 20630). Fordiesel engines with diesel particulate filter (DPF/FAP). Special short-distance vehicles and city vehicles are primarily affected by problems with clogged diesel particulate filters. For professional repair shop use only. Cleaning is made with the compressed air gun for DPF (item no. 7946) and the specially developed DPF-Probe with 5 interchangeable tips (part no. 7945). The diesel particle filter must be accessed depending on the vehicle type. In order to do this, the temperature or pressure sensor on the diesel particle filter must be removed on most vehicles. Observe: When cleaning, the particle filter's temperature should be below 104F. On some vehicles the diesel particle filter is located near to the exhaust manifold or, optionally, the turbocharger, and not on the vehicle underbody. For safety reasons, utmost care must be taken when cleaning such vehicles - cleaning or flushing liquid may otherwise enter the combustion chamber through an open exhaust valve. The appropriate Pro-Line spray probe for the vehicle type is then fed into the particle filter through the opening. The full container of Pro-Line cleaner for diesel particle filters (1 liter) is sprayed directly onto the surface of the particle filter in intervals of 5 to 10 seconds (each with a break of 5 to 10 seconds in between) at an operating pressure of87 to 116 psi. The probe must be rotated and moved back and forth during cleaning in order to cover as much of the filter surface with Pro-Line cleaner. The particle filter is then flushed with the full container of Pro-Line flushing liquid for diesel particle filters (500 ml). The compressed air gun for DPF (item no. 7946) is also used here at the same intervals as during the cleaning process. The particulate deposits are dissolved during the cleaning process and distributed around the diesel particle filter, where they can then be burned off as part of normal regeneration. After reinstalling the sensor, the service centre or workshop must trigger regeneration according to the manufacturers' instruction. Caution: The protective measures for safe handling can be found in the safety data sheet.

• Guarantees Low Fuel Consumption
• Optimal Engine Performance
• Reduces Operating Costs
• Dissolves Soot

The LIQUI MOLY Pro-Line Diesel Particulate Filter Purge is a specialized cleaning fluid designed for professional repair shops to effectively dissolve soot and contaminants within diesel particulate filters (DPF). This 500mL solution restores optimal engine performance and helps reduce fuel consumption by ensuring the DPF functions correctly. It is compatible with Fordiesel engines equipped with DPF/FAP systems, particularly targeting short-distance and city vehicles that are prone to filter clogging. Regular use of this product, in combination with the recommended cleaning tools, can prevent costly repairs and maintain the vehicle’s emission compliance.
Application of the LIQUI MOLY Pro-Line DPF cleaner involves a careful process. The cleaner must be used alongside the Pro-Line DPF Pressurized Tank Spray Gun, DPF-Probe with five interchangeable tips, and optionally a long spray probe. During cleaning, the vehicle’s exhaust temperature should be below 104°F to prevent damage, and the process involves spraying the cleaner directly onto the filter surface in intervals of 5 to 10 seconds, with pauses in between. The probe is moved and rotated to ensure thorough coverage. After the cleaning cycle, the filter is flushed with the accompanying Pro-Line flushing liquid, and the particulate deposits are dissolved and redistributed within the filter.
This process allows the soot and carbon deposits to burn off during normal regeneration cycles, ultimately restoring the DPF’s efficiency. Proper handling procedures and safety measures are essential, especially when working near the exhaust manifold or turbocharger, to prevent liquids from entering the engine's combustion chamber. Once reinstalled, the vehicle's service technician must trigger a regeneration cycle according to the manufacturer's instructions, ensuring the filter is fully cleaned and operational.
The LIQUI MOLY Pro-Line DPF cleaner offers several key benefits including guaranteed low fuel consumption, improved engine performance, and reduced operating costs. Its targeted formula effectively dissolves soot buildup, helping maintain compliance with emissions standards and prolonging the lifespan of the DPF system. For professional use only, this product is an essential part of diesel engine maintenance, especially for vehicles operating in environments that promote rapid DPF clogging. Proper application and safety precautions are detailed in the included safety data sheet to ensure safe handling during the cleaning process.
