I was on vacation last week. I drove approx 1k miles to my destination. And while at my location I drove approx. 15 miles each way around town. On the 3rd day I drove 45 miles to my destination and on the way back the "drive to clean filter" message came on after approx 30 miles. By the time I reached my destination it had completed regen. This is the first time this message has come up. I would have thought that during the road trip it would have cleaned the dpf enough to where this message would not have popped up. Since at home sometimes I don't drive it as much and this message had never came up. The truck has approx 45k miles.

 

Where you towing on this trip? My experience is with towing my 5er, I have not been given the "drive to clean" message, but once I unhook and run it in the 15 minute continuous range, then I will get the message. I have only gotten it on 2 occassions since the PCM was replaced in March. But still skeptical of what I am seeing, and I keep up with what others are witnessing with the new flashes. I am beginning to think what is "logical" with these Rengens, we should actually be thinking what is "illogical."

 

I wasn't towing. I drove the same distance last year (without towing) and did not get the message anytime since I bought the truck. Don't know if the flash had anything to do with it. The thing I don't like about the flash is not getting the message cleaning filter to stay on during the entire cycle. I know you can check by going through the setup button but its not the same. Before I knew exactly how many miles it would go into regen. Now I check about every ten miles to see if its still in regen, that is when I don't forget or get distracted. Just seemed out of the ordinary for my driving habits to get this message especially after a long trip and several regens during trip.

 

Hard to say why and I would not worry about it to tell you the truth. While coming down here to FL this year I was regening every 150-170 miles. Usually it is every 130 miles while towing heavy.

Who knows...everything can effect the regen cycle.
