Liqui Moly Pro-Line Diesel Particulate Filter Purge is a highly effective neutralising and rinsing fluid used after cleaning the diesel particulate filter with Liqui Moly Pro-Line Diesel Particulate Filter Cleaner. The purge solution flushes out loosened and dissolved soot residues, redistributing them evenly within the DPF so they can be safely burned off during normal regeneration. This product neutralises the cleaner and is designed for use with the diesel particulate filter installed, eliminating the need for costly DPF removal or replacement. It is especially effective for vehicles driven mainly on short distances, where incomplete regeneration commonly leads to DPF clogging. Regular use helps maintain optimal exhaust system performance and significantly reduces operating and maintenance costs.
