🎊 How Do You Trigger A Dpf Regeneration

Answered by Honest John. There is no DPF regeneration signal on anything. No car has one. They should have and it would be easy to rig via a heat sensor, but manufacturers choose not to fit them because it reminds drivers of an inconvenience of owning a diesel. I have a Renault Koleos which is the same vehicle with a different body. Diesel particulate filter (DPF) regeneration is one of the largest pain points for school bus operators and maintenance technicians. It’s not uncommon to hear of fleets who experience multiple regen issues a day, causing their buses to remain parked or on the side of the road in need of a manual regen. “It’s been a pain,” said Charlie My understanding is the primary driver for DpF regens is a timer based on engine run hours. This can be overridden by a pressure sensors. If the engine does not complete a regen it will try and do a full (10min) regen at the next opportunity . Sent from AutoGuide.com Free App [/color. Sadly sometimes diesel from the DPF regeneration process can leak into the sump oil (google it) diluting and degrading the oil and hence causing problems with the lubrication of the turbo bearings. Sometimes the oil level can rise to a point where the engine ‘runs away’. It can happen on any car which uses this type of DPF regeneration process. Regeneration can be spontaneous (if temperatures in the DPF reach burn-off), or triggered by the diesel ECM. Problems can arise if the vehicle is not driven for a sufficient amount of time to complete a successful regeneration. If this occurs several times, the DPF can be overloaded and the MIL will trigger. The next suggestion was to force a regeneration to try and bring the ECU back into alignment. On the previous 2 occasions the dpf light has been triggered by the ECU I have driven it literally 100’s of miles on the motorway and it will not go off without a forced regen by the garage. David. If you are usually under load the EGT during normal highway driving may be sufficient to cause passive regeneration to occur. That said - Starts and Stops along the way will stop the regen process if the DPF output Temp sensor drop below 550 degrees (somewhere in that range - I don’t have the TSB on hand so that’s from memory) .
