F350 def alarm

[NEnative]

I drive a 2016 f350. I would like to know if anyone has found a mod to add a chime to the def filter cleaning warning that comes up on our display. The small orange display that pops up for a few seconds is easy to miss so I hope to add an alarm/chime so it catches my attention. Thanks everyone.

I politely disagree. Knowing how often your DPF is cleaned will at least keep you from making unbelievable statements like “I’ve driven my (whatever brand) Diesel for over 20,000 miles and it has NEVER cleaned!” :W

Ya got me there.

My BMW X5 diesel does a regeneration about every 500 miles, which I know only because I’ve added instrumentation to watch exhaust gas temperatures. In normal use, they run in the neighborhood of 300 degrees C. When they suddenly shoot up over 500 degrees, it’s due to a dpf regeneration. BMW provides no little light or other marker. It’s supposed to be totally invisible to the owner/driver, because after all it’s supposed to be something you don’t need to worry your little head about. All anti-pollution measures are required to be totally invisible to owner/operators. The DEF system is the only one allowed to violate that, and only because it was shown to be so effective. And only then after a huge fight.

I have a Scan Gauge II and I programed it to show regen, that is the only way I know its in regen and when its done. I also have it show exhaust temp on the first sensor and it is interesting seeing it hit 1100 degrees sometimes.

I’d need to see some actual ECM log data to believe that.

I have driven my RAM 54K miles and only once after the fact figured out that it had been in regen.

I've got the % full DPF display on mine and find the DPF cleans every 500 miles. When the 500 miles is up the filter will be only from 20 to 40% full if the previous clean was allowed to finish. If the truck gets shut off before cleaning is done it might reach 80% full next time the 500 miles is up. I think the reason the % full display is not provided from the factory is that it's not worth driving extra miles to finish a cleaning cycle.

Check on the Ford Enthusiast forum site. I see there is a way you can add a percentage display for the DPF in a program called Forscan. Forscan is a software that is available on for your phone than interfaces the truck via certain OBD modules. I have no experience with it but it's out there.

You are correct guys, I did mean dpf, sorry about that. Thank you for the replies.

[naturist]

I’ve never heard of a vehicle that has a def filter, so I, too, suspect you mean the dpf, ie the diesel particulate filter. This isn’t anything worth your attention and the fact there’s even a light that blinks momentarily is more notice than most vehicles give you.

I believe you mean dpf. I don't know of any audible alarm but you can take your truck to the Ford dealer and have the add the dpf status scream that shows you a percent full status of your dpf and this way you can predict when a regen will occur.
