Liqui Moly Combo of Pro-Line Diesel Particulate Filter Cleaner (1L) & Purge (500ml)

Restore your diesel vehicle’s DPF system to top performance with this two-step professional kit. Ideal for workshops and serious DIYers who want to address blocked or inefficient diesel particulate filters (DPF/FAP).

What’s included

• 1 L Cleaner – breaks down soot and contaminant build-up inside the DPF.
• 500 ml Purge – flushes and disperses the loosened residue so it can be burned off during regeneration.

Why this combo matters

• Diesel particulate filters trap soot and ash from the exhaust. Over time, these deposits build up, restricting exhaust flow and reducing engine performance.
• The Cleaner tackles the core of the problem by dissolving the accumulated soot deposits. (As described: “Dissolves contaminants inside DPF units, restores vehicle performance and fuel consumption.”)
• The Purge then ensures the loosened material is safely dispersed and ready for regeneration: “Flushes the soot softened by the cleaner … The cleaner is neutralised by the Purge.”
• Together, the kit helps:
  • Improve exhaust flow and lower back-pressure
  • Restore engine responsiveness
  • Reduce fuel consumption
  • Extend DPF life and avoid costly replacements
