VW/Audi DPF cleaning kit. This diesel particulate filter cleaner from Liqui-Moly is designed to provide a low cost solution to replacing clogged diesel particulate filters. When the DPF becomes clogged the ECU usually starts the regeneration process. This would typically burn away the soot build up in the DPF. If you constantly use your TDI for short trips around the city the cataylitic converter never gets up to a hot enough temperature to burn these particles. This is when your DPF light comes on. Instead of spending thousands of dollars to replace your "clogged" DPF this kit will allow you to clean the unit while it is still installed on your vehicle. The kit includes the spray wand, hose, 5 nozzles, the spray canister, the DPF cleaning fluid, and the DPF purge fluid. This tool requires the use of an air tank to push the fluid into your DPF for a proper cleaning.
The Diesel Particulate Filter captures ash and burned particles from the exhaust system. The VW/Audi DPF cleaning kit is designed to remove soot that is normally burned in the regeneration process, but the DPF will still fill up with metallic remnants that cannot be burned away. To prevent this build up make sure to use the VW approved fluids in your VW/Audi TDI. A VW 507 oil is specially blended for the clean diesel TDI engine to minimize DPF clogging.
