Specialist diesel particulate filter cleaning saves money and keeps our customers on the road. 

An overloaded diesel particulate filter (DPF) is expensive to replace – not to mention the time spent wasted thanks to a lengthy stay in the workshop when problems need to be resolved. 
 
That’s where expert solutions from DR Automotive can help. Our DPF cleaning services are designed to keep you moving and ensure your car continues to perform at optimal levels, rather than undertaking costly replacement. After all, prevention is better than cure. 

How does a diesel particulate filter work? 

All new diesel cars are now required to be fitted with a DPF, which aims to cut emissions by catching soot (diesel particulates) in the exhaust. 
 
To maintain the filter’s performance, this soot must be emptied in a process called regeneration. However, incomplete regeneration and soot build-up over time can cause significant problems including lack of power and high fuel consumption. 
 
If regeneration is interrupted and soot loading continues to increase, replacement of the filter is inevitable – at a potential cost of between £600 and £4,000 depending on the make and model of your car (plus labour and diagnostic time). 
There is an alternative: Fast and efficient diesel particulate cleaning rather than replacement.

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, pipes 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.
