DPF units are a costly experience to replace when they block up. This was the driver that led us to develop DPF cleaning technology over a few years that is a proven process to clean out the carbon and ash deposits from DPFs.
The DPF cleaning technique involves deconstructing the DPF unit to expose the internals, then washing off all heavy and coarse carbon and ash. Then the unit is placed in our state-of-the-art German manufactured DPF cleaning machine. We engaged a chemical engineer to work with us to formulate a chemical compound that will dissolve carbon and ash, without damaging the filter, oxygen catalysis or casing. This DPF cleaning process removes the fine carbon particles that have built up internally. After the cleaning process is complete we rinse out the remaining chemical, dry and flow test the unit. Following successful flow test results, the DPF unit is then reconstructed and ready for collection.
A blocked DPF is a symptom of a problem, it is not the cause of a problem. Make sure you have rectified the cause of your DPF becoming blocked before you send your DPF for cleaning, or you may find that the DPF may block again. Download our DPF blockage checklist to diagnose the problem.
