I have also seen an increase in regen frequency this summer. I was averaging 800 miles or so now they are happening in the 120-150 mile range for about the past month ????? 20,000 + miles.
So much for good fuel millage. 20+ is great but when you factor in the regen at 12, it sucks. I don't drive much, but it seems that every time I go out in it, it's on a regen cycle. I get pissed, so I do my own version of regen. ( cycle the key ) Fixes the problem and back to good millage. The warrenty will take care of any problems I should encure. After that I can do a total exaust and chip refit. They should have some good ones out by then.
Vinnie - if I read that right, you're stopping the regen by stopping and restarting the truck? If so, you are asking for a clogged DPF which will result in horrible mileage and an expensive repair. The soot in the DPF needs to be burned out or it will eventually completely restrict the exhaust. You may have saved a few dollars in fuel cost only to spend a couple of thousand later after the vehicle is out of warranty. I'm pretty sure Ford will review the regen logs on your truck if it fails within the warranty period and if it shows a willful failure to Drive to Clean, they may have a case to deny your claim. If you're worried about the regen, don't. It's no big deal. Just let the truck do it's thing and it will be fine.
Yes if you keep resetting the key eventually the truck will go into limp mode and you will not be able to go into a regen. It will have to go into Ford where they can then force it to go into regen when idling with their laptop. It will not be under warranty.
Don't stop the regen every time. Let it do it's job.
The 6.7L handles this process with great improvement over the 6.4L.
It just starts back up again later.
ruschejj,
The active regen distance on the Edge isn't working yet.
It has been stuck on 219 miles and I had a regen yesterday.
RedneckTrucker, I like the way you think, there are certainly factors affecting number of regens. However whether they can be properly quantified and whether they are significant to the overall outcome is hard to say. I do a fair bit of highway driving and I've noticed that I do more regens running at 60 vs 75 so the amount of engine load is a factor (as has been previously mentioned with towing vs not towing). However despite more regens my fuel mileage is still way better at 60 vs 75, so the fuel burnt in a regen is not a big deal for me.
I'd love to see the active regen distance in action it would provide greater insight into what affects the process of soot buildup. I love monitoring these types of things however I wonder how much it matters in the end. If I'm busy I'm still gonna drive that truck harder than if I have more time!
It matters very little with this truck, at least so far.
Regardless, I monitor these types of things for no reason other than I want to.
The soot GPL count (whatever GPL is) is working and it hit 2.30 today and soon after began another regen (I had one yesterday but had to interrupt it).
I'll attempt to pay attention to see if all regens begin at 2.30.
Nothing like 14.3 MPG without towing something so it better clean itself out on a 600 mile drive this weekend.
With my luck, the truck will save up until I'm driving 15 miles to work Monday morning.
