LIQUI MOLY DPF Cleaning Fluid 1 Liter for BMW, Audi, Porsche Cayenne, Mercedes-Benz, Dodge Sprinter, and VW Diesels (2005–2025)

Clogged diesel particulate filters on clean diesel engines are the target of LIQUI MOLY DPF Cleaning Fluid, a 1-liter cleaner for the BMW, Audi, Porsche Cayenne, Mercedes-Benz, Dodge Sprinter, and Volkswagen diesels in the fitment table. The fluid quickly dissolves the contamination built up inside the filter. LIQUI MOLY presents it as a way to avoid the cost of replacing the filter. It is made in Germany. A particulate filter collects soot from the exhaust stream, and when deposits build faster than regeneration can burn them off, the filter clogs.

This product carries a 24-month, 24,000-mile warranty.

This cleaning fluid is the first step of LIQUI MOLY's DPF service. After the cleaning fluid, LIQUI MOLY follows with part 20112, the 500 ml DPF Cleaning Flush. The flush spreads the loosened deposits through the filter so they can burn off during normal regeneration. For application, LIQUI MOLY pairs the fluids with part 7945, the DPF Cleaning Wand Kit, and part 7946, the DPF Spray Gun. Ordering all four together gives you the complete process in one order. LIQUI MOLY has made its own additives in Ulm-Lehr, Germany, since 1978.
