The DPF light comes on to tell you that there’s a problem with your car’s diesel particulate filter. This is something that has been fitted to diesel cars since 2009 to reduce the amount of soot released through the car’s exhaust system, lowering emissions. This soot is harmful and can cause respiratory problems. Hyundai Tucson Ultimate new in April 2023. Petrol driven (got rid of first diesel ever bought prior to this because of PDF warnings all the time). 1600cc engine with 3 driving modes. On 19/12/23 warning light to keep driving and regenerate exhaust filter. Didn’t know it had an exhaust filter but NOT impressed. Make sure you’re using the correct type of fuel for your vehicle. Some fuels can damage the DPF system. If your DPF warning light is on, there are a few things you can do to try and clear it. First, make sure you’re driving enough to allow the DPF to regenerate. If that doesn’t work, you can try a DPF forced regeneration cycle. Diesel Particulate Filter (DPF) u0007DPF collects and stores PM on the walls and surfaces inside the DPF. u0007DPF oxidizes soot via regeneration when the temperatures are high enough. u0007Ash is trapped and accumulated inside the DPF. Ash will accumulate and may, in time, clog the DPF, which will necessitate DPF replacement. To begin with, DPF stands for Diesel Particulate Filter. In short, the DPF system is a filtration system designed to trap soot and prevent it from exiting the tailpipe and entering the atmosphere from your diesel-powered engine. Low sulfur highway diesel and EGR systems have been integrated into modern diesel engines to help reduce harmful NOx Who monitors DPF regeneration on those engines? I jumped on ScanGauge when they come with x-gauge for it and drove about 3000 miles to date observing when regeneration happens. It never did, at least according to ScanGauge. I use truck with 5000 lb camper, so it is under constant load and usually drive 300 miles a day. The lights on a Volvo dashboard follow a traffic light colour system: Green: the system is working correctly or is currently in use. Orange: something is not working correctly - take extra care and check it out as soon as possible. Red: there is a serious, and potentially dangerous problem - stop driving as soon as it is safe to do so. Seems ridiculous to assume that this short procedure could make any difference.After all, as the manual says, the DPF light flashing indicates that the DPF requires regeneration by driving for 10-15 minutes at a specified high level of revs to burn off the accumulated particulate. And if you can’t regenerate it, you have to replace it. If you look in the handbook it tells you that if the dpf light comes on then you have to drive for as long as possible above 2000 rpm until the light goes off. If you go by that theory most of the time when the dpf light isn’t on then you will stop it from coming on as the higher rpm burns the soot off. uj5x0I.

how long can you drive with dpf light on
