Anyone has an explanation why I keep getting this? Im trying to force regen my truck.
jelizard, i know you are past this now but i figured i would share my experiences in hopes it will help someone else.

I'm guessing possibly the message you were seeing "Condition not met: Brake pedal pressed" is that you were pressing the break pedal when the instructions say not to touch the brake or accelerator pedals.

With a lot less highway driving lately my truck has been doing regens a lot and I too ignored the 90, 100% warnings until it was too late and I got the "Exhaust Filter 100% Full. Service Required. See Dealer." error. I scheduled an appointment with my dealer who couldnt get me in for a week and said they would need it overnight. I decided to take a chance on the AlfaODB, bought a cheap Amazon fire tablet and bluetooth ODB and gave it a try. It was pretty finicky to get started, the sequence of events was pretty specific and I almost gave up but here was the exact sequence required:

a) Start the truck and drive around or let it idle until the coolant temperature > 60 C / 142 F as shown on the dash (or in the AlfaODB)
b) Plug in and pair the bluetooth adapter in AlfaODB, select your vehicle year/model/etc. My truck is a 2017 and AlfaODB report it as a 2015 Bosch EDC17 ECU.
c) With the key/ignition in the on position but truck not started use the AlfaODB Faults screen to read all faults then clear faults.
d) Turn the ignition completely off, wait a moment, then back to ignition on/not started
e) Select "DPF Regeneration Enabling" from the AlfaODB Active Diagnostics screen
f) Start the truck, then -- with no pedals pressed -- immediately select "Particulate filter regeneration" from the AlfaODB Active Diagnostics screen
Note, the only time I pressed the brake pedal at all in any of this is for a split second when starting the engine for step f. If the truck is not up to temp, pedals are pressed, codes are present or the DPF Regeneration Enabling trigger is not set this step will fail.
g) Assuming you got the sequence correct, when the "Particular filter regeneration" starts the truck's idle will raise to around 2500. Go back in the house and come back 20-25 minutes later, the truck will drop back to a normal idle and the dash errors (Service Required, See Dealer, etc) will go away on their own when it finishes.

For me the AlfaODB showed a soot level of around 140% before I started this and 9% after it finished and it took about 25 minutes.

The other advice about the dealer making sure nothing else is failed like a melted injector or that kind of thing is still good advice, but if you know you do a little too much city driving and sometimes the truck misses out on a full regen then this is a cheap way to take care of it yourself.

I did a forced regen using Alfa and I thought it was a very simple process.

I mostly have Hwy driving and never see regen message on the dash, every few months I use the alfa obd to do a parked regen anyways. Works well to keep the filter happy.
