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.
You wife's trips amount to four possible regen attempts, so maybe that was enough to make the light come on. I've never had the light come on, so not really all that sure how it works.
