LIQUI MOLY DPF Cleaning Flush 500 ml for BMW, Audi, Porsche Cayenne, Mercedes-Benz, Dodge Sprinter, and VW Diesels (2005–2025)

LIQUI MOLY DPF Cleaning Flush is a 500 ml flushing liquid. It goes through a diesel particulate filter right after the filter has been treated with LIQUI MOLY DPF Cleaning Fluid, and it fits the clean diesel BMW, Audi, Porsche Cayenne, Mercedes-Benz, Dodge Sprinter, and Volkswagen models in the table. The flush dissolves the particulate deposits that the cleaning fluid has loosened and spreads them around the filter. From there, the deposits burn off during the filter's normal regeneration. It is made in Germany. A diesel particulate filter traps soot from the exhaust, and the engine periodically burns that soot off in a process called regeneration.

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

The flush is the second step in a two-fluid process, so it is not used by itself. LIQUI MOLY pairs it with part 20110, the DPF Cleaning Fluid, which goes in first. LIQUI MOLY also matches it with part 7945, the DPF Cleaning Wand Kit, and part 7946, the DPF Spray Gun, for applying the fluids. The cleaning fluid comes in a 1-liter container. The flush is the smaller 500 ml container that finishes the job. LIQUI MOLY was founded in Ulm, Germany, in 1957, and it develops and produces its additives in Germany.

Apply the flush only after the filter has been cleaned with the 20110 cleaning fluid. LIQUI MOLY's wand kit and spray gun are the tools it pairs with this process. The loosened deposits then burn off as part of the vehicle's normal regeneration.

Common Questions

Do I need the cleaning fluid as well?
Yes. The flush is meant for use after the filter has been treated with LIQUI MOLY 20110 DPF Cleaning Fluid.

Where do the dissolved deposits go?
The flush spreads them around the filter, where they burn off during normal regeneration.
