Hello Pedro. I'm an apprentice mechanic in Alberta Canada. I really appreciate your putting your knowledge and experience for us to watch and even learn from. Thank you

Hello Pedro. Thanks for sharing your mechanical skills through your videos. I been having a major soot problem with my 2011 freightliner cascadia with a detriot dd15 engine. I changed my 1Box because my old box had a lot of rust around it causing weak areas to leak air. And it had high levels of soot as well at the time. After replacing the 1BOX l cleaned the filter that came with it and l blew out SCR filter as well. After driving for a week the system is totally clogged up again. I was so clogged that it blew the clamp because of the clogged 1box. I towed it to the local freightliner dealership to have the truck checked. After 2 days they confirm the system was clogged up really bad and they would need to order new dpf filters and air clean the SCR filters in the 1box. I explained to him l just had the filters cleaned and l had the 1box SCR FILTERS blown out a week ago. I told the shop supervisor that's a lot of soot build up in a week. I ask him did he think it could be a problem on the engine side that would cause that amount of soot in a week. He said they will check to see if there was an issue with the engine. I never received a call they emailed me letting me know my truck repair was completed. I called them to get a run down of what they did and I was told they replaced the dpf filters repair 2 coolant leaks and they blew out the 1box filters. I ask the service person if they check to see what was causing the soot build up. He said because the dpf filters were bad because they were the original filters in the 1box and they failed the flow test. So after picking up the truck and driving it on the 3rd the truck seems like it running out of fuel and stop on the side of the interstate . I called road side assistant to bring fuel and filters after getting the truck to run it kept cutting off. After the 5th try l gave it gas this time and there was a large pop and black soot went everywhere. The 1box was completely clogged up again. The truck sounded good got over 7 miles to the gallon but its producing a lot of soot. The most common reason for too much soot is fuel and air mixture in the cylinder isn't correct to burn the fuel causing soot buildup. I'm not loosing oil or coolant other than the 2 leaking hoses that was supposed to be replaced but they are still leaking because the shop used the same old compression hose clamps. Pedro if you experience any repair jobs like this l would appreciate your feedback. Thanks in advance.

Good video, thanks for posting, I do read some comments questioning ur repair without knowing anything ignore them you are actually fixing the real cause of issues. I seen technician who can change every part of aftertreatment including one box without knowing the real concept most stealer-ship have those so called master tech😂.

I knew about the injector been plugged. I clean mine once a year. But thank you for the information on the in and out temps. Learned something new.

That sent me to the poor house,I replaced the one box,and still couldn t do a regen,finally, it was the DEF quality control valve (or something like that). The dealer in Knoxville assured me that once the box was replaced my troubles would be over,box was replaced and they took an extra 7 days to find the real problem,I paid for their incompetence... 20k doesn t sound like a lot,but it is a lot when the freight rates are very bad,almost 2 yrs later I can see light at the end of the tunnel debtwise. I learned that Credit card companies charge a lot to finance 20k,I'd never used a c/c this way.

Yo bud mad respect for your attitude towards sharing knowledge that doesn't necessarily grow on trees. But to maybe get you to see if you can pick up what I'm putting down. Regarding the ability to read in real time as the zone/levels of soot as they come down, on how certain programs do not oblige such data stream as you would like. Now just hear me out a second. I might not even be making any sense in recommending to use the data monitoring of the delta-p. Sensor before, during, and after. IDK!! ,WHAT U THINK BUD?

Its a joy watching ur videos, very good way to show and teach Thank you so much God Bless

check the fuel filter and see if the pin is broke off and fell into the fuel line restricting the fuel flow that will not allow the regen to get hot enough to regen the engine that is why Ash levels, to be higher this is what happened to my dd15,

Great job on the video👍🏻

2011 cascadia code ecc 61 spn 3719 fail 00. Also code cab 33 spn 522116 has pretty much always been on. Ambient temp sensor was replaced a while back and temp has beem reading correctly. Both ecm computers and the transmissiom were replaced about 20k miles ago. Truck is doing parked regen now i initiated that because it was deratging at like 3mph. Also fuel has only been lowing from drivers side tank for the last few months since we removed fuel filter system that used to be installed but was getting old and broken

You do provide very important and valuable information,thank you.

My rpm going up to 1300! But it goes back down after 3 minutes. Freightliner says first step is removing def dozer valve

OTR. I had same issues. Honestly it’s not work. Until you clean dpf filter. The reason why this code come after 600000 miles because your dpf filter need to cooked. Why this code don’t come before 500000 mile or 600000 mile because your dpf filter clean. The smoke not cross completely to dpf filter cause of too much Corbin. The the smoke come to back to the injector 7th. You clean 7th. It’s work only few days. Again same issue.

I have a code 3242 and a high soot level and the dozer valve and dozer injector are not activating while doing a parked regen. Also the temps do not rise above 496 degrees. I did replace the dozer block and cleaned the dozer injector and it still doesn’t regen the regen aborts after about 40 min

Which tool would you recommend to owner operators who want to diagnose their own trucks? Good video, sir, as always. Thank you!!

Thank you for sharing your knowledge

This type of work makes your light come on the next day

Why didn't you replace the doser instead of cleaning it? Any reason?

Great video man

I'm beginning to wonder if it's a problem with the Cascadia, as I've driven a few and they seem to want to conk out on when in lower gears, as I've noticed some sputtering and more hesitation when I've driven both the 10 speed and auto in the lower gears. That's my take on this. Could be that's where the soot build up is more noticeable as well too. I don't know.

Delete it and you won't torture yourself and your pocket. When those systems fail it is impossible to fix it,especially when the truck starts to burn oil which is normal for trucks over 500k miles. No technicians can fix them believe it or not.

The biggest fix to the DEF problem, is to never purchase a truck with DPF emissions. Money pit...

No codes soot level high forced regen aborts what can it be?

Great video

Bro great channel! New sub!

Good job 👍

After Regn my truck showed all signs stop engine and started warning buzzer i shut down the engine and start it again all sign gone their own

Red light came on because temperature was too low?

So I'm is. Having issues. Doing a parked regen it idles. Up and boost to about 28 psi for maybe 30 sec to 2 min max the shuts down then try agin maybe 3 times in a row. But the regen light is. Off when trying but will try that same prosses a couple min later until you drive. Also motive the same thing if the light comes. On boost to 28 psi them drops boost bit keeps rpms up at 1200 ish have you seen this befor what can I do to fix this also nli have no lights no codes

Would the ceramic gaskets on the tubing prior to the filters caused the heat to escape in the filters not get hot enough when doing a regen? This is a pre-one box Cascadia with the DD 15

I deleted mine. No more problems.

In my truck i cant remove that sensor.

Will a truck with a bad oil pressure sensor not complete a regen

I usually change my fuel filters an the regent will complete with out a problem. I usually get a abnormal doser pressure warning when regen will not complete.

Where do u get the Detroit software and how much is it? I checked ebay but idk if that money will go to waste

Hi Pedro, I’m in Montebello too and wanted to speak with you regarding some repairs

I have 2016 Cascadia truck. I have code of soot level high i tried to do regen it doesn’t run without engine fan off. Now i turned on the engine fan now regen is in progress but it has been more than 50 mints its not giving me the reading of nox inlet/outlet/conversion efficiency and many others. I also changed ACM. Please reply asap.

Ey Pedro mi camión hace regen asta dos veces por día es mbe900 2008 freightliner, tira humo azul cuando lo hace eso es normal ?

Hello. I'm using DDDL 8.13 and cant start parked regeneration. Can you give me some tips please?

Hey, on my truck 2014 freightliner cascadia dd15 spn102fmi18 code comes on and goes away automatically when i drive up hills

If it's the 1 box 📦. I'm out of 1 truck

Hey Pedro, what would be to much DOC inlet pressure to do a regular regen ?? I have this issue with a 2014 cascadia, face pressure was in the 3 psi range, had the filters in the box completely cleaned, after installation, system still requesting regen/ soot level high, did a regen and the doc inlet pressure was at 1.4psi, which is weird since the filters got cleaned, should I do a DOC face plug regen ?

Hi Pedro. Recently I got the codes ACM520342 17 and SSAM 520762 -5 and SSAM 520761 also 5. So I had to put my truck into Authorized Freightliner shop in Calgary, Alberta, Canada. It is New West truck Dealership . My truck is Freightliner 2020 with 190 000 MI on it with Automatic Transitions D12. I have Purchased this truck from the same Dealership in Calgary , Alberta, Canada. My Truck is sitting there for 8 days already and seems to me they still can't solve the problem. Today I had a chance to get into my truck and go trough Diagnostic. At that time I could see those previously faulty codes are gone and there is a only faulty code I haven't seen before. A new faulty code is ACM 3609 12. Wasn't there before. Please help me out to understand what is going on with my truck. Your response will be greatly appreciated. Thank you

I got the check engine light on with engine 2(4) fault, I'm not sure what that means, the acceleration goes up to 800rpm, and I couldn't go more than 1000 rpm with my foot on the accelerator . Please advise anyone. It's freightliner 2015

Need some help with Dd15. DEPF filter Clean, EGR Clean, DEF doser Clean, DEF filter Replace 5 months ago, but the truck keep asking for Rgen every 500 miles. Any idea what can be the problem?

Hey was wondering if you can help me out. I have a 2017 frightliner cascadia. I have a code 520349 14 DPF filter efficiency low. I had the filters cleaned and doser unit and injector replaced. Also replaced soot sensor. Cleared code reset dpf filter soot level and performed soot sensor test. Soot sensor passed and regend. Code stayed as permanent and after driving for 2 to 3 hours code comes back. Any suggestions? Thank you.

Thank you so much. Do you have shop ? I can go check it up ?

I have a 2013 Cascadia. Truck asking for regen but will not engage. Tried to have it force regen but thats not working either. Any idea what could be blocking the truck from regen process?

I'm having this current issue. I have a 2017 freightliner Cascadia. What should I do?

Hey brother I am having issues with my truck how can I contact you for a question?

Bro I got SPN 4374 FMI 0 showing up and got derate do you know if I can take the speed sensor off and make the running speed come back a little bit?

Actually is deleting the def on the evo something i can do

Can I still drive with regan problem ? Does it deal with thermostat ? Or

I have that code and the esc I parked in the shop and now it won’t start any help?

what percentage should the doser injector status stay at during a regen

What is the scanner tool ??

These companies need to stop trying to outdo each other with more technology. They should be trying to make these trucks as simple as possible. The fewer parts they have the less there is to go wrong.

Is there a way to do a forced regen on my tripac Evolution? Has code 13 and im not able to regen while driving

Please help I have 2012 cascedia. We did the regen and the light still flashing and also the engine light came on both the yellow and the red one. The truck will cut off in like 5 minutes. It’s giving me a code eec61 and spn3556. Thanks

What temperature does it newd in tye morning parked regen..when cold

I haven't the same issue with my 2015 Freightliner, I have spent about $5k through a Freightliner dealership, still not able to resolve the issue for me. I'm on the East Coast, do you have any paid online session to troubleshoot?

Hello bro, Great video. I have one question. I have taken my truck to the mechanic shop 3 to 4 times already. The problem is when the truck ask for regen and then I park and start the regen manually by pressing the regen button and then it starts revving up the RPM as usual and then after few mins the fan starts and then the truck jumps every time when fan clicks like it misfires or something and then after truck regen sound goes to normal but RPM stays up between 12 to 1300 rpm and its not doing anymore regen but acting like it's doing. Please advise the truck is 2014 cascadia

Thnx Man

how much cost this diagnostic software ?

I did the regen, but the regen light is still on and speed limited to 55mph

I have a question

Hey guys, im a mechanic out Bakersfield ca. I am having this issue bueno the difference is that my fuel cut off valve is at 0% and won't come on. I have changed the doser block, 7th injector, engine harness, and qcv and still no luck. Anyone had this problem or have an idea?

Hi Carlos. I have this codes 061 spn 5443 15 dd13 cascadia and 061 spn 3719 0. Both amber check engine and red flashing light. Wont let me do regen truck shuts off and DOC temperature inlet not reaching temperature for regen to start. I clean fuel doser and S pipe. You think i should replace delta pressure sensor?

I have the small regen light flashing( the one where the DEF gauge is at) after doing 2 regen which took about 40 mins each which is a normal regen time. What are the most likely reason of that?

at 9:56

Wheres your location sir

Its been 15k miles and my def still full. Any advice?

Hi Pedro, I have a problem with my 2012 Cascadia 700k miles. Just cleaned filters put them back in and when I wanted to do forced regen it starts but instead of staying on 1500RPM it goes back to 1100 for a second and then back to 1500 for 5-10 seconds and then goes down again and circles like that all the time… DOC temp is around 380 when it starts but slowly getting up. Had to stop doing regen because I thought something is broken… no fault codes except the NOx sensor permanent… do you think it’s only nox or something more serious? My mechanic tells me it’s probably turbo not building up the temperature, but turbo shouldn’t make my engine RPM go low from time to time while doing forced regen. Never had any issues with this truck whatsoever

I wish I could sue the Freightliner of Knoxville,Tn they replaced my box for $17,000.00 my issue was that it didn t reach the temperature,they replaced it,and still didn t reach the temperature,they spend a few more days and then they replaced the "def quality valve" And that fixed it, now I am having the same issue and it s been 7 months. I hate this truck and I hate the damned EPA that pushes crap down our throat.

All of crap on the dash is clogging the filter

I got a 2012 cadcadia it started yesterday with the idle not working cruise control works fine but idle not working is hot over in Texas when to sleep let the truck running for my AC with no idle because is not working this morning woke up I see check engine light and Regen light flashing tried to hit the Regen button but did not work in January of this year I freihtliner change filter box meter unit def pump new filters I have one code eec 061 spn3719 16 what can it be

I'm so done with the DPF system. What a freaking waste of space 🙄
