Hello, I would like to know if without a DPF the SCR catalyst gets clogged with soot. I want to delete just DPF, and have the SCR system coded out of the ECU but I don't know if I can leave the physical box without having clogging problems in the future. Thank you
I know this is an older video but I had a question. How much were parts all together, and how much did you charge? You linked all the parts you used so I can check that out, but if I wanted a mechanic to perform the delete my vehicle instead of me, I would love a ballpark quote. Once I eventually have enough money to delete my baby, I will definitely be using your videos to help aid me. Thank you so much
Yes the diesel particulate filter catches this and turns it into ash. It actually gets stored in the diesel particulate filter, which eventually needs replaced because it gets filled up with ash.
Hey Munky, thanks for all the videos it’s helped me do all this work to my car. Quick question on the spring clamp that holds the DPF to the turbo, should this be tightened until it stops or just until there is tension on the spring? Mine doesn’t feel like it’s getting any tighter so have stopped to er on the side of caution.
They don't get tight like a normal bolt would because of the spring. Once the slack is taken out of it it will start to feel tight. But then it feels the same when you keep turning it. So don't over do it. Just a few turns once it starts to feel tight should be good.I have seen people break them because they over do it.
@@MunkysGarage Thank you appreciate it! I was a bit surprised when I got to the motor mount arm and found the steering column in the way which made things a lot more awkward, the joy of being in the UK with right hand drive. What are you doing with yourself these days?
I could possibly be the bearing seals in the turbos are starting to go bad and some of that oil gets into the intake which would possibly cause the blue smoke. The other could be the pcv system.
You will need to eliminate the SCR cat if you remove the DPF because the metering valve for the exhaust fluid is eliminated when removing the DPF. This will cause issues with the SCR cat due to DEF not being sprayed into it.
There is definitely a odor of diesel fuel from the vehicle with catless down pipes. There is very little intrusion into the cabin. The only time I have noticed the smell inside is when getting stuck in traffic where I am sitting still for long periods of time. It is very minimal tho and definitely livable in my opinion.
Just want to clarify so there is no confusion. If you are talking about the dpf, which is right off the turbochargers, I used the one from VRSF. If you are referring to the scr cat down stream in the exhaust, behind the transmission, I have been cutting that one open and removing the catalyst material and then welding it back up.
Hey Munky and all other viewers of this clip, I got a BMW 325D -06, enginecode M57TUD30, with a mileage of nearly 450000km.. What's sad is that i dunno whats done to it, all i know is that the DPF is gone, and maybe the swirlflaps.. The regenerate-light sometimes lights up, is that because it's not truly deleted from the cars software? It's time for the yearly inspection in 23 days, and i start to panic a bit xD PLEASE, reply and help me!
can you just do an EGR delete to get rid of the CBU? Can a tune be made just for that? My SCR and NOX sensors are still under warranty for another 1 year
I have never done just an EGR delete. All of the vehicles I have worked on have been the works. But I don't see why you couldn't do just the EGR delete. It would definitely eliminate the carbon buildup issue.
Yeah the owners of these I stay in contact with are getting between 41-44mpg highway consistently with very aggressive driving. I'm sure with fuel economy type driving it would get 50 easy.
Car will be fine on the first key cycle. When you shut if off and restart it set faults and goes into reduced power mode. You can clear the faults and then be able to restart it again once without faults. It was driven straight to the tuner after I worked on it to have it tuned for the emissions stuff no longer being installed.
I Have a 2011 335D and am in the process of doing this delete. Tried to find your IG but seems like you changed it? How can I get in contact with you and your garage would love to have you guys finish the delete for me
Honestly not much louder than stock. Could very easily be lived with from day to day. These cars have quite a bit of sound deadening material in them so not much outside noise gets in.
When you started it for the first time after doing all the deletes, did you get a SES light? was the car running in limp mode? Essentially what i’m asking is after i do my deletes, can i drive it to the tuner to get tuned or will I have to get it towed?
You will get one startup after doing the deletes. When you shut it off and start it again it will set faults for not seeing the egr valve connected and go into limp mode. That being said you can clear the fault and start it again and all will be good until you turn it off and start it again. So yes you can drive it to get tuned. Just keep a small scan tool with you in case you need to stop and restart it.
Tune is definitely necessary after all of this work. I had this vehicle tuned by a shop local to me called Stage Fabrication and Performance. They can actually tune the ECU itself without the car being there. So if you are not local to them but would like you use them you can contact them and mail your ECU in the for the tune.
I'm assuming you're talking about the two that come from the differential pressure sensor at the rear. I take one of the hoses off and loop the other back onto the nipple to seal the sensor off so it doesn't get messed up from humidity or dirt. Just in case someone wants to return it to stock
I live in a State where deleted are a big no no... I have an x5 35d I think I’ll buy a newer Tahoe later in its life. I’m only at 145k now with stock config. Soot mass in DPF is at 33g which seems healthy. I drive the highway often.🤞
slagletoby soot mass at 33g is pretty high. Are you sure you don’t mean ash mass? My soot mass is currently at 12g according to Carly and it regens around 15g.
Yes true story. I’ve been getting a DPF engine light recently. I have Carly and ISTA+, I’ve been trying to figure out if my DPF is actually on its way out or not. It’s been successfully cycling regens about every 250 miles or so, my DPF exhaust pressure sensor seems to be working fine, fuel mileage is average at 18 city, 26 Hwy, 22 combined, power is good too. It totally unsure yet because it runs strong and seems healthy. I was thinking about pulling out the DPF and doing a reverse flush to make sure there’s no ash plugging the screen causing blockage. After regens it climbs back op to 30.7 Soot and 39 Ash after 100 miles. Could be on the fritz! I need to run some back pressure tests that’s the tell-all if it’s clogged or not.
slagletoby those numbers seem strange, also you’re MPG is terrible. I get 33mpg combined. Have you checked your coolant temperature? The thermostats go out on these and kill your MPG and affect the regens.
Mike B Thanks Mike I’ll keep trying to figure out what’s going on. According to what I’m reading online soot mass at 30g is within spec. I have recently seen 18g but that was about a month ago, I have also seen up to 40g a few months back. After regen my MPG’s go up but settle back down to factory spec 18 City/26 Highway after monitoring for 100+ miles. I see up to 31 MPG on flat ground going 50 MPH but that doesn’t count. This is an x5, not a 330d which it weight/wind load different. I did some basic maintenance yesterday checking things out with my Depsteck optical scope cam. I have a broken CCV hose, just ordered a new one from Tunemyearo.com, the broken CCV was blowing sooty air in the engine compartment and getting into the air box making my air filter very dirty. Cleaned K&N air filter and will replace CCV hose this weekend. Not sure if that has to do with anything, likely not. I’m going to run back pressure test today, I might have a bad Exhaust Pressure Sensor, check the 2 hoses with scope cam they look ok. I did check the coolant temp and it running consistently at 190 degrees which is in spec. Good thought on the coolant temp, that was one of my first observations. Thanks for the ideas...
When they are deleted and tuned yes. The black smoke is a result of the vehicle being tuned and putting in a lot more fuel to make power, and the emissions stuff not being there to counteract it.
The tune that is done to it after the emissions things are removed. It's s personal preference thing. Most tuners can either make it run clean, or they add more fuel in than is necessary and it causes it to smoke like that. Some people like it blowing black smoke like that when they accelerate.
Planning on doing this on my car actually. Only difference is I’m gonna be running the ATM Catted downpipe. Just out of curiosity, how many hours did it take you for the whole job?
It took me around 7 hours to do everything. If you've never done it before it can easily be done in a weekend. If I were doing this to my own car I would use the catted downpipe as well. This was one of my co-workers cars. I have also done another co-workers car as well. Without the cat they soot up the back of the car like crazy and smell really bad of diesel when you are sitting still.
Munky & Rooster's Garage ok cool. Yah I feel pretty comfortable to do the EGR delete and swirl flap delete. I’m definitely a bit apprehensive about the DPF delete along with the carbon cleaning. Do you know if the SCR cat needs to be deleted? Or can it be kept and doubling as a resonator? What tune do you run after deletes?
@@Driven.ByVlad You can leave the scr cat in place if you would like. Both of my co-workers deleted it and it definitely made the exhaust a little louder. So leaving it would surely act as a resonator/muffler and keep the noise down. As far as the tuning process both of my co-workers took there car to a local shop that tuned them for the things being deleted. I'm sure there are some generic tunes you can get to load into the car. I always recommended having it tuned at a shop that has a dyno, as this is the best method for tuning properly.
Munky & Rooster's Garage ok, I’ll definitely try to drive it with it in place, I’ve read some people say it gets clogged and other say they run it 100% fine! So I might just cut it out and put a resonator in its place. oh yah, I 100% would prefer a tune like that too! I unfortunately don’t have any local tuners for m57’s. But Ryan from BBR is great, and he creates custom tunes for each customer even if they are remote. I’m Not sure where you are located, but Ryan is honestly one of the most knowledgeable tuners for this platform in the US.
@@Driven.ByVlad I have never seen the SCR cat actually clog up. I know they go bad in the higher mileage vehicles and set faults until they are replaced. The exhaust doesn't get crazy loud without it there. In the ones I have seen without the DPF or the SCR it is only slightly louder. The one thing you do get is a lot more turbo noise. Since you are going with a catted downpipe you may be ok to delete it and get a little more turbo noise without a super loud exhaust.
Sounds good even with the stock mufflers on.
Was not expecting to see the overflow lot for my dealership at the end
Boutta do this on m’y 2011 335d 😂 this is gonna help a ton thank you

I was charging $1000 for all the work. That was working out of my garage at home. A shop would probably be double that.
@@MunkysGarageare you still charging that ?
Did you ever figure out a solution to get that sensor that wouldn't fit into the downpipe
I did not. I ended up not needing that sensor.
Good day folks, any recommendations on where to purchase the exhaust pipe ? thanks in advance.
is there a way to not have so much black smoke but still have the dpf removed and the car tuned?
There are a few people offering tunes that don't smoke as much.
That's alot of smoke does the DPF prevent it. I had a 2004 VW Passat 2.0 and on heavy acceleration, it would smoke.
Yes the diesel particulate filter catches this and turns it into ash. It actually gets stored in the diesel particulate filter, which eventually needs replaced because it gets filled up with ash.

can you do mine next ?
Why is the car blowing blue smoke when revving it? My car does the same thing and I’m not sure why. Im also deleted and tuned
I could possibly be the bearing seals in the turbos are starting to go bad and some of that oil gets into the intake which would possibly cause the blue smoke. The other could be the pcv system.
Hi @MunkysGarage is it necessary to do the SCR Cat delete after DPF delete or it is optional?
You will need to eliminate the SCR cat if you remove the DPF because the metering valve for the exhaust fluid is eliminated when removing the DPF. This will cause issues with the SCR cat due to DEF not being sprayed into it.
@@MunkysGarage thanks a lot
Hello. Did you find out what is the other senson besides oxygen sensor goes into the down pipe?
Do catless downpipes smell bad at all? If it does, does it penetrate the cabin at all?
There is definitely a odor of diesel fuel from the vehicle with catless down pipes. There is very little intrusion into the cabin. The only time I have noticed the smell inside is when getting stuck in traffic where I am sitting still for long periods of time. It is very minimal tho and definitely livable in my opinion.
@@MunkysGarage perfect i was worried about a catless downpipe and an SCR delete that the smell would be unbearable. thanks for tips
Hello Munky's Garage. Just have a quick question, where did you get scr delete for BMW?
Just want to clarify so there is no confusion. If you are talking about the dpf, which is right off the turbochargers, I used the one from VRSF. If you are referring to the scr cat down stream in the exhaust, behind the transmission, I have been cutting that one open and removing the catalyst material and then welding it back up.
@@MunkysGarage yeah I alredy replaced my dpf with the down pipe. Was just wondering about scr. Thank you for reply.
Did you guys deleted the Dpf from dme?
Yes sir
Hello. What kind of sensor have to go back into the down pipe?
The oxygen sensor and first exhaust temperature sensor are the only ones that have to go back.
@@MunkysGarage Ok. Thank you
Hi! After you fitted the dpf delete pipe did you have to map out the dpf?
Yeah the tune we put on the car turned off all the monitors for the emissions components that were removed.
Did he just hollow out the SCR or install a delete pipe?
Hollowed out the scr.

What did you do with the vacuum hose that was connected to DPF?
Looped one of them back onto the pressure sensor to seal up the hose ports so moisture couldn't get in and cause damage.
@@MunkysGarage Ok. Thank you!
with the SCR delete, you can also get better gas mileage with a tune, correct?
Yeah the owners of these I stay in contact with are getting between 41-44mpg highway consistently with very aggressive driving. I'm sure with fuel economy type driving it would get 50 easy.
Sounds like a truck lmfao
What tune is that ?
Was done my a shop local to where im at.
When you did the egr delete did the car go into limp mode? Of did you remap the ECU
Car will be fine on the first key cycle. When you shut if off and restart it set faults and goes into reduced power mode. You can clear the faults and then be able to restart it again once without faults. It was driven straight to the tuner after I worked on it to have it tuned for the emissions stuff no longer being installed.

If the car doesn’t get tuned does it stay into limp mode or the car drives normal?

It's a bad tune, too much smoke than other stage 2 35d's

Deleted my 09 335d on the 1st of Jan, running a Dumd stage 2 tune. Having issues with injectors due too the tune and just redid the VCG lol
Which tune did you get?
😂 that smoke dosnt feel right coming from the exhauste 😂
now Greta can sleep better at night :)
Not to be “that guy” but I wish mine smoked like thst just for when people are riding my ass
I can tell you it is annoying because of how bad it soots up the back of the car. But it is so enjoyable to smoke things out behind you.
Why anyone would do this is beyond me. Just get a car that can be fast without the smoke.
That’s bogus! Buy a petrol
Lmao
