A common cause for a DPF regen failing is that the software you’re using isn’t clearing the vehicle as “safe.”. The following conditions must be met for the software to clear the vehicle or else the vehicle cannot initiate regeneration: Parking brake is set. Clutch is not pressed in. Accelerator pedal is not pressed in. Particle Filter Emergency Regeneration. Prerequisites: Ignition ON. Engine ON (Idle) Oil Temperature above 70 °C (see MVB 007.2) Particle Filter Load below 68g (see MVB 104.3) If the Particle Filter Load is above 68g the Particle Filter needs to be replaced since the car may burn down when regenerating. Passive Regeneration: This occurs when you are driving your vehicle. To trigger this process, you must drive the vehicle for at least 15 minutes and at 40 mph. When you do so, the exhaust heats up and starts burning the soot off. Active Regeneration: However, if you do not succeed in triggering passive regeneration then active regeneration For context, I'm retired, drive short hops only, and therefore never trigger a passive regen. The Jeep has 10,600 miles. The Jeep has 10,600 miles. A few months ago my Jeep was regening about twice as often as usual and the DPF%s were bouncing around erratically, as opposed to increasing 1% at time. Can't believe a blocked DPF would cause significant performance problems with it putting the DPF warning light on first. I've an OBD reader in my car which now picks up EGT as well. I believe to have seen one regeneration on the motorway where EGT increased from normally 350-400C to 600 and stayed there for 20 minutes. The DPF is a crucial component of the tractor’s emissions control system, and regular cleaning ensures optimal performance. Follow the manufacturer’s guidelines on cleaning frequency and procedures. 2. Use high-quality diesel fuel. Low-quality or contaminated fuel can lead to increased carbon buildup in the DPF, hindering regeneration. Location. Valparaiso, IN. TDI. 2013 Jetta TDI + Premium. Mar 29, 2014. #2. Yes the car will attempt another Regen next time you drive. If you interrupt too many in a row you will get a warning light (I believe it's the DPF light) and you will have to take the car to the dealership to have them force a regen using a Vag-Com. 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. To prevent clogging, DPFs clean themselves from time to time by burning off accumulated soot. This process is referred to as regeneration, because the DPF is working to “regen” itself to its original state. When everything is working as it should, regeneration occurs automatically while the vehicle is in motion, unnoticeable to the driver. Typically, once the DPF light comes on, a 20-minute drive at 55 mph will force the regen process to convert the soot and ash and turn off the dash light. As with the stationary method, in some cases the vehicle will need to travel at a slow rate of speed until the DPF cools down and turns off the dash light. Operators need to further understand fX7D.
