- Essential after-treatment for a fully cleaned DPF - Supports fast and efficient regeneration - Developed for professional use High-quality flushing fluid for effectively flushing a cleaned built-in diesel particulate filter (DPF / soot filter). The 5in1 DPF Flush constitutes step 2 of the cleaning process and helps prevent costly repairs and replacement of the DPF. Features • Flushes the diesel particulate filter completely in one treatment • Removes loosened soot and cleaning residues • Supports and restores optimal engine performance • No disassembly of the particulate filter required • Easy to apply • Clear instructions available via an animation video • Instructions for use During step 1, the soot is loosened and evenly distributed in the diesel particulate filter so that it can be burned off during normal regeneration. Application: after using the 5in1 Diesel Particulate Filter Cleaner (STEP 1), the particulate filter must be flushed with the entire contents of the 5in1 Diesel Particulate Filter Flush (STEP 2). Perform the same steps as described in STEP 1. After the flushing process is complete, reinstall the pressure or temperature sensor. Subsequently, the maintenance service or workshop must perform a test drive of at least 20 minutes to activate the regeneration of the diesel particulate filter. If the engine electronics do not automatically start the regeneration, we recommend manually initiating the regeneration process using a diagnostic tester or a suitable readout device from the workshop.
