SCR Performance Low is really wide term when it comes to Volvo. It could be number things that will trigger this massage to pop up. It could be Inlet or Outlet Nox Sensors, DEF Doser Valve, EGR Cooler or EGR Valve, 7th Injector and list goes on.
Thats why you look up the code. The code will tell you where to start in the possible cause area. With his engine code Doser valve was 1 of the possibilities along with Def quality Def clogged lines n control module.
@Cedric Diggs i would think it was self-explanatory that you have to look at the code when I said it could be multiple different things. One thing you have to remember is that a lot of times when you get SCR Performance Low you won't get code pointing you to the right issue right away, and you have run diagnostics on all those things I mentioned above to find out which part triggers SCR Performance Low.
thanks for posting this video! here is something that every truck driver should have in their tool box,it saved my ass few times OTR Reset Tool | Volvo & Mack 2014 - 2020 | Forced DPF Regen | Reset Aftertreatment System | Clear Active/Inactive Codes
other problem that could be the reason you were actually getting scr code in the mount that you bolt the doser valve to likes to crack at the weld I actually spotted in the the video @5:23 you can see the crack with white crysalized def was seeping out that could cause multiple def false errors to come up
Always try cleaning that thing first and then regen. Did that o a Freightliner yesterday. Performance was definitely low but it would be with how caked up it was.
Hey there I have a question my truck went into a full derate 5mph and I have changed the doser valve it was caked up after do I need to get it towed to the shop to get the codes reset because it's still in derate mode.
Awesome man Great channel I'm planning to buy a truck Any recomendation?? Is for OTR I live in California and I love drive volvos but I cannot afford a new one 😫
Man, I hate the DEF systems. When they work, they work. When they don't, what a pain to figure it out. Hope you got it fixed for a good while. Any update on they headlight polish? WLBS
It seems to be fine now. But I usually have issues in the colder weather. So time will tell. Headlights are good. But they are showing signs of yellow again. I seen some on the volvo parked next to me in this video that I think I will order in a couple months.
you could have run the truck with the dozer valve off and see it it worked, it sprays intermittent shots of def. Think the problem was more with inlet being needed to be cleaned.
Thanks for the video, having the same issue. I bought a CanDo Hd Mobile scan tool $399 on sale that can clear codes and force a regen. Worth every penny. OTR makes one as well. Please follow up after a month to see if that took care of it.
@@Coronado-nz7wu wow. I’ve heard it was more expensive. Is there a way you can send me any info like model number or link. I would really appreciate that. I’ll need to get it
Yes everything is still good on my truck as well. I did replace both nox sensors at the end of June though. One of them went out, so I did both to be safe. Hope y’all are doing good..
I had to spend around $4k for a complete diagnostic tool to avoid going to the dealer every time CEL came on due to SCR's low performance. Every dealer visit to turn off CEL would cost me $400.
PLEASE save your self the headache and further derates and have a shop weld the hairline crack @5:26 on the DPF OUTLET MODULE above the def dosage valve mounting. Inspect the below from the outlet module to the scr inlet for cracks or bad gaskets etc.
I cleaned it with a wire brush and water. There is no crack. It was just Residue that looked like one. But thank you for the info and pointing out what to look for. It’s much appreciated.
@@TruckingLife Unfortunately it is cracked. it's a hairline crack and cleaning the area with a wire brush makes it harder to see, not easier. The easiest way to tell is to perform a stationary regen with that shield off so you have a clear view of the area. When the DPF gets close to 1000* in the middle of the regen, you'll see the crack expand A LOT. Stainless steel expands and contracts a lot with temperature variations. I have around 25 trucks with that model DPF and they all crack there.
Did you ever fix that crack? I noticed it on our 2012 Mack Mp8 too, looked exactly like this one does. This Def system is an absolute nightmare, still getting lightning bolt
Don’t do it lol my friend did that to his volvo and had to put everything back again cause there’s a lot of sensors and had to pay 30k when he could’ve just wasted like 10k and buy new dpf filter (3k) & scr catalyst (5k)
EPA troll bait lol. Not worth it. But you need a great wrench and we don't see enough of the 180 an hour dealer rates to be worth the 750 a month check starting in 10 years when Cancer rates spoke from rolling in DEF to maintain these properly. It's too specific, too touchy, overly governed with software and exposed to the elements to be done the way it should. Nobody can show me a video non stop of a shop doing this right in the time they say it takes without exposing the tech to the terrible chemicals.
If you have over 800k miles, change your scr box, or put nox sensors, dosers, and on and on, it will do the same thing, low performance, poor quality, engine derate stuff like that
Thank you for the nice video that code came up on my truck I was I was driving through Texarkana stop in West Memphis have my mechanics fix it since it's company truck they're going to be upset that I know what's wrong with it hopefully it won't take it 4 days to fix if so I'll do the damn thing myself thank you again
Perfect cause I work on a Peterbilt dealership but I have a Mack with the same Aftertreatment system I can see the new dozer has a metal Dower instead of a black plastic right? Cause I did had a crack on the decomposition tube next to the dozer I welded it and it fixed it but it just came back I’ll replaced that dozer and hopefully it finish the fix
@@TruckingLife 5:23 you checked your eyes con can clearly see the crack on the decomposition tube man I’m a diesel tech you don’t fool me haha Look right you can even see the def coming out of that pipe after the dozer bolt on
How do you like the Mack? I’m thinking about getting a Mack or a Pete next. I have had the Volvo for just over 4 years now. Time for an upgrade or a second truck.
@@TruckingLife I don’t own bro I work on a Perterbilt Dealership!! I’ve worked on a freightliner dealer also but I always recommend Peterbilt all the way every day
I have a 2014 with the D13. I see Volvo acknowledged the known issue in these motors and set aside 780 million to address it. This was announced in 2019. Has anyone found what the real fix is
Did you figure out what was the problem? I have same msg on dash and they telling me I need scr and it’s 5k , also that I need both inlet and outlet nox sensor
@@TruckingLife they replaced my scr and put the inlet and outlet nox sensors & it’s been doing good, I cleaned the EGR cooler before this happened and the dpf filter because before all this on January black smoke was coming out the exhaust and it was the injectors but after they changed the injectors that’s when it kept asking for regen and poor def quality so that’s when they changed the scr and nox sensors
My 2018 international can't go more than 5mph am see a SCR error severe debate stop engine on the dash along with four check lights one blinking what can I do tonget going
I have a 2013 Volvo d13 and I got a check engine code: spn 5394 fmi 17 My question is how serious is this code? Can I make a trip? It had me do a manual regen. Then I drove it for like 10 miles, parked, shut off engine. When I drove it after the regen the check engine light disappeared. But after I shut it off for 5-10 minutes and started it back up again, the check engine light came back on with the same code... How serious is this? Safe to go 200 miles
I’m not sure. I have been able to continue driving mine. I get those same codes every time I’m in Wyoming. Mine ends up clearing itself usually. So I hardly let it worry me. But you could be something else. I’m sure mine is a sensor acting up.

Yes I agree
I took to dealer, code was p20ee00
They said it’s not saying exactly point we have to look at each of all that possible cases.
Your first mistake is going to a ta. Your second mistake is listening to somebody who works there.

Get the OTR performance reset tool. It will clear codes and removed 5mph limit. It will save the trip to the dealer too.
I will have to get one. Thanks
I had one, it doesn't do special commands like " EXIT INDUCEMENT" which is SCR performance-related code. Premium Tech Tool is needed to fix it.
Thank you. I’ll look into a better one as well.
How is it running now? I notice that there is crack everywhere on your box where the def dower mounted.

Really Helpful.

Is it like a callback for this issue or they just acknowledge it and you have to get it fixed on your own?
What was your messages on the dash? Mine says poor quality def detected and asking for parked regen
Did you figure out what was the problem? I have same msg on dash and they telling me I need scr and it’s 5k , also that I need both inlet and outlet nox sensor

Your def dose house is cracked around the dose valve. Need welding. If not welding you will still have problem. I see on the video is cracked.

You’re right. I should have used one.
Macks regen system on mp7 is absolute garbage
You could just have tried cleaning it. It does become clogged
Yes sir. It was cheap to replace so I just replaced it.
Is it called an exhaust inlet valve. So I can Google on how to clean it. Thanks
I really wish they would stop putting all this crap on trucks. Plastic useless CRAP. Those engineers have been unbridled for too long.
