The DPF Cleaning Process:
Stage 1: In Depth DPF Diagnostics

We carry out an in depth diagnostics, checking that the key components and sensors are functioning correctly before initiating a DPF clean. Where necessary, further investigation is carried to ensure a successful clean. We carry various common DPF sensors, pipe’s etc in stock so that we can quickly have you back on the road in the event that your DPF problem is actually a component failure.

Stage 2: The DPF Cleaning Process

Using our specialist cleaning system, a carbon cleaning solution is injected into the pre DPF pressure line and soak period is now initiated. The engine is then ran at a fast idle allowing the soak fluid to clean the carbon content in the DPF. This is then followed by a further injection of a cleaning flush solution during an engine fast idle cycle and we carry out the flushing process twice.

Stage 3: Live Data and DPF Analysis

Finally, live data is analysed during a road test or DPF regeneration. This is then followed by final parameter checks logging DPF back pressure readings. These readings, before and after, are then reported back to you for your peace of mind. The three stage DPF cleaning process is now complete.

The whole process takes approximately 2 hours to complete.
