If the lightis working correctly,it means you have failed to complete several attempts at a regen. Not really sure how many you have to miss for the light to come on. It comes on continuously when the filter starts to gets a certain percentage full and then it flashes when you are close to full.vexorg said:Second regen time this morning, 1100 miles. Which was bad timing as my wife had been on 2 longish trips in the past 2 days, just over 20 miles each way on Monday, and then about 20 miles each way yesterday. This morning she said it must be trying to "do it's cleaning thing" as the fan was running on. As she has no plans to go anywhere else this week other than short trips into town, I thought I'd take it for work.
The dpf light was on when I started it. And stayed on for about 20-ish miles until it had finished. There's a noticeable kick in acceleration as it finishes.
What would the light be on? It didn't come on last time. And it had a few long trips beforehand so wouldn't have had any real failed attempts.
If you really are alwaysgetting the DPF warning light flashing, then I think that should be something to be concerned about. Are you absolutely sure it's the DPF warning light that's flashing?mannp said:I always get a flashing light, I onlyhad the continuous light once and that was when the car was new.Should I get the continuous light first before it starts to flash, if so then thats something I need to tell the dealership.

I'm 100% sure its the DPF light and I only get a flashing light and thats probably twice a week.Inchindown said:If you really are alwaysgetting the DPF warning light flashing, then I think that should be something to be concerned about.

There are three stages to a DPF regeneration.
First the car tries to do an automatic regen with no indication being given other than how it affects your MPG. For most people this happens about every 500 miles or so.
Second, if the car fails to complete several automatic regen attempts, the DPF warning light will come continuously. This means the car is telling you the filter is starting to become blocked.
Third, if you fail to complete more regens after the continuous light comes on, the light will start to flash. This is telling you the filter is almost completely blocked. At this point you should get the car on the open road and drive above 30MPH with the revs above 2000 until the light goes out. Failure to do this will cause the filter to completed block and this can have expensive consequences. You could do serious damage to the filter system and might need to have it replaced. This will not be covered by your warranty.
