Diesel Exhaust Filter Cleaning.

I have 2015 Ford F350 PS that hasn't been driven much for last 6 months due to back surgery. Lately I have taken on some short trips and seems like just before I get home a screen pops up on my DIC that says something to the effect "Exhaust Filter Cleaning" for about 4 seconds then goes way. When it goes away is done or should be drive around the block and let it complete the cycle? Should I take on highway and drive it? I going fill up the tank today because we are leaving for the Caribbean and won't be back to the end of the month and just going to sit while we are gone.

Kenny,
When it says that what is doing and how does it cleaning the filter? Might be dumb question but if don't know you have to ask.

Diesel Exhaust Filter Cleaning.

It's dumping extra fuel, and super heating your diesel particulate filter.

That link should be required reading for diesel truck owners. I quote from the link but there lot more good information on the link.

"If the regeneration is unsuccessful due to an insufficient driving cycle the extra fuel injected into the cylinders will not burn and will drain into the sump. As a result, oil quality will deteriorate and the level will rise. Most DPF equipped engines will have an oil quality/viscosity sensor but it is important that you check that the oil level does not increase above the maximum level on the dipstick as diesel engines can run on their own oil if the level is excessive – often to the point of destruction. If you ignore the DPF warning light and keep driving in a relatively slow, stop/start pattern, soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will need to take the car to a dealer for 'forced' regeneration."


All I can say is WOW.... Glad I asked. I guess there isn't any dumb questions. Off to check the oil level and drive on the highway.

When I was at Ford, I had a little old lady customer with a vw golf tdi.

Every few months, she would bring her car in for me to force a manual regen cycle.

I had the cable and vw software to do this. She just didn't drive it enough, and was fine paying us to do this.

The regen takes more than a few seconds. On mine ( see sig) it takes a good 30 mins of driving at speed. I added an Edge Iniight engine monitor which allows me to see the soot level and when I am in regen. I can also force a regen if needed. If I know I am going on a 30 min+ drive and am close to regen with no long trips planned after that , I will force the regen and be OK. .

Reading the manual is always a good idea, GM has this in a separate manual that comes with the duramax.

If it's a newer ford then it's dumping def not fuel I thought?? You need a good run on the hwy to exercise that puppy. Regens take more than a few seconds. If you see the screen pop up I would at least drive it for 15-20 mins if you haven't driven it much lately.

DEF is constantly being injected. Very small amounts.
