Best DPF Cleaner Overview

By running your car in this manner, you regenerate the DPF Filter and unclog all the soot and dirt that’s built up over time. A DPF system works sitting in between the vehicle engine and exhaust system. It’s a small to medium sized filter which catches exhaust soot and then stores it in the filter instead of it being pumped out of the exhaust and into the atmosphere. A passive regeneration occurs when the vehicle exhaust system has reached a particular temperature after a sustained period of driving at specific speeds. Generally, this occurs when driving on a motorway at speeds of around 50-70mph for more than 30 minutes. The Used Car Guy holds no liability for your outcomes when trying the procedure listed above.
