DPF Cleaner (1L) & DPF Purge (500ml) Kit

Highly effective 2-step system for cleaning and flushing clogged diesel particulate filters (DPF) without removal. The cleaner dissolves stubborn soot and deposits, while the flush distributes and neutralises residues so they can be burned off during normal regeneration. Helps restore engine performance, improve fuel efficiency, and prevent costly repairs. Suitable for passenger car diesel engines with DPF/FAP.

Application:

Apply using a DPF spray gun and probe via the sensor opening (DPF below 40 °C). Spray cleaner in intervals, allow to soak (15 minutes), then flush in the same manner. Reinstall the sensor and carry out regeneration as per the manufacturer's instructions. Depressurise and empty the equipment after use.
