Dpf temps

[Soulreaver0102]

Hello everyone. Truck had been doing pretty good up until lately with regens. It has started just before Christmas asking for a regen on dash where I could actually push the button to start the process. First time it has ever done that since I’ve owned it. Bought in February 19 started running it in April. So I pushed button let it do it’s thing and away I went. But noticed it was doing a regen or trying to often. I took filter out. Replaced gaskets and clamps throughout the exhaust system weekend just before Christmas cause I could smell raw diesel whenever it would regen. Do good Monday then Tuesday It started asking for a regen again. I didn’t perform one after gaskets cause a friend had my laptop and didn’t get it back until Tuesday night. Well figured I’d take the load headed about 2 hours away and let it regen running down the road. Seemed ok but back at it again today with wanting to regen. I didn’t work Wednesday so seems like once a day on most days it wants to or tries to. So. To my point. I’m sitting in truck doing a regen now and inlet temp is about 100 degrees less than outlet temp. Inlet is 1010 and outlet 1100 doc 673. Is that normal on temps. Also had some inactive codes when I plugged in. I’ll try and post pic but it was 5397 2 counts and 3251 5 counts. 2012 Freightliner cascadia 2250 656,000 miles. Last pic is during regen
