To reduce emissions, diesel cars are fitted with a Diesel Particulate Filter (DPF) – something that filters and catches soot particles. Most DPFs will automatically clear as they’re used but on rare occasions, in specific circumstances, they may get blocked and require manual cleaning. In normal use, a DPF cleans or regenerates itself by During both active and passive regenerations the EGT jumps up to between 1200 and 1500 degrees F. for about 5 to 10 minutes. These high EGTs are the reason many people do not shut down their engine during a regen. These temperatures are high enough that they might do harm to the turbocharger.
The DPF light will then go out and you can resume your normal driving. DPF LIGHT FLASHING A flashing DPF light means the exhaust filter is just about full and the truck cannot go much farther. Complete a “parked regeneration” as soon as possible. DPF LIGHT FLASHING WITH BEEPING ALARM A flashing DPF light with an audible alarm means the
On my car I had to correct the p2015 issue before I could fix the dpf issue. If you're also getting a check engine light you need to sort that out first. In my case I sorted it with a $60 part I was easily able to install myself. And if you can afford it, get the adapter cord so you can run vcds from your diagnostic port.
As it says on the box, a DPF is there to catch diesel particulates (or soot). Indeed, it’s designed to reduce the amount of particulates making it out into the atmosphere by 80 percent. However, because a DPF, just like any filter, has a limited capacity to filter before it becomes clogged, it has a bunch of sensors built in that will see it
I made three (3) round trips of 2,200 miles (1.1K each way) over a 9 month period before attending to the internally cracked DPF. I did have well over month of around town driving prior to the 1st road trip & was comfortable with the car & situation. Prior to the first round trip, I made similar inquiries to yours (most were on TDI FB groups). 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. pR5uFTj.
