During the initial three instances of DPF cleaning, your vehicle may not display any messages on the dashboard. However, there are subtle indications that the cleaning process is happening. These include observing the engine idling at 1100 rpm, which then gradually drops to 800 rpm. Additionally, you may notice a slight increase in power At the same time, the driver will usually be alerted by DPF warning lights flashing on the dash while this active regen is in progress. Once started, the process must be allowed to complete, which typically means driving the vehicle for a certain distance or time (five to 25 minutes is typical) at a defined minimum speed (usually about 80km/h The diesel particulate filter, which is part of the Mercedes-Benz truck exhaust after-treatment system, reduces particulate emissions to a virtually undetectable level. However, from time to time it is necessary to clean the filter and burn off the accumulated soot particles. A good DPF cleaning company must have at least 5 years of successful cleaning experience. They can also determine if the DPF is in fact damaged internally. A mechanic can test the DPF on the vehicle to determine if it is blocked. They cannot confirm if the DPF is collapsed or melted internally creating the blockage. The average clean for a Helping my viewers save Money on their Mercedes Sprinter Maintenance.Amazon Removed me from being a Affiliate so they told me to Removed all my Affiliate Lin The "cleaning" process is actually the oxidation (burning) of the soot (carbon) deposited in the ceramic filter. Performing a successful regeneration requires high enough exhaust gas temperatures to ignite (light off) the soot in the DPF, a bit like using a match to light a piece of paper. Make the paper hot enough and it will start to burn by Purchase a DPF cleaning additive to help clear the ash and soot. This bottle of fluid is designed to break down the ash and soot that's clogging the filter. Visit your local motor supply store or look online to purchase a cleaning additive. Regeneration Process (Regen) Regen is the process of burning off the built up diesel particulate matter (DPM) in the diesel particulate filter (DPF). There are three regen strategies for the 6.7L Ford, passive, active, and manual. One of the requirements for any regen to start is the exhaust gas temperature must reach between 950° and 1050° F. – “CLEANING EXHAUST FILTER CONTINUE DRIVING” – “DIESEL PARTIC FILTER IS FULL CONTINUE DRIVING” – “DIESEL PARTIC (Particulate) FILTER IS FULL CONTINUED DRIVING MANDATORY” – Either DIC message may be accompanied by DTC P2463. The DPF will clean itself as part of normal operation. Several factors including fuel consumed, hours of A diesel particulate filter is one of the most important elements of the exhaust system. It is designed to reduce diesel particulate matter emissions by 80%. However, this unit is prone to wear and tear. Its limited capacity means it should empty the soot to work properly. AtXvCP.
