Great info, I’ve already done this procedure once on my own vehicle a few years ago. I’m about to do another tomorrow I’m feeling a bit discouraged lol. I did the first one on a lift, took about 5 hrs after work for everything under the car and another 5 hrs after work for all the egr stuff up top and just buttoning everything up. This next one is gonna be in a driveway, wish me luck.
Took mine off our audi a3 1.6 cayc engine last month....for a good "clean"....wow...had to lower the subframe to get it off as it was at the back of the engine, no lift, just on axle stands on my back for what felt like the whole weekend...the garage was very impressed 👍
2002 330d ,226k runs like clockwork ,no dpf ,no egr ,no inlet butterflies ,no engine light ,love it ,great vid mate cheers
What happens at mot? Want to get this done to my tt just worried about mot
Hi there. A mate has this engine in his 3 series. I'll link the video to him. I have an old Peugeot 306 IDI turbo diesel, which I've tuned up a bit and de-catted. To be honest, I couldn't cope with the constant anxieties of running a modern diesel, especially as I rarely drive far enough to get exhaust filters hot enough to burn the crap out of them. The sole minus side for me is that I have to cough up £300 a year in road tax for a car that isn't worth much more than that, but it's worth it for trouble free motoring.
All the best to you.
N57 notes: having removed this yesterday a few updates on Georges video.
1. Engine mount and support is different on N57, engine mount is 1x 18mm bolt on the side of the engine mount. You do not need to remove the heatshield on top of the engine support
2. The four bolts holding the engine support to the engine are in a better place, and the upper most forward bolt can be seen from the wheel arch looking in.
3. Before you remove the engine mount or engine support, take the bolt out that connects the two then jack the engine to get the mount split from the support, liklihood is they will be corroded together and will need a good whack to get them apart (spraying penetrating fluid into the bolt hole may help). You can get them out as a pair but it is very, very tight and you will need to pry them out.
4. The temperature probe at the top of the dpf is very tight and the nut is not the strongest, take care when removing it. The replacement is £85 from bmw. 14mm tight spanner needed as ring spanner will not fit over the connector.
5. Order a new exhaust flexi (70mm x 150mm) just incase (£30) if you damage it when removing, it's not worth putting back in without renewing this.
It's not a bad job to do on the drive in my opinion, just take all the dpf side 21mm subframe bolts out and loosen the opposite side right off. Engine support is optional if you jack it from below, the aircon line on the dpf side runs exactly where the support is used in this video so i ran it from the engine earth point side and then the dpf side top mount at the back (need to remove scuttle plastics)
😂😂 so glad it wasn't just me that found it hard i forgot to put the dpf back in first when i changed the engine on my e70 🤦♂and had to figure out how to get it back in on the driveway same as you spent whole day under the car so the frustration anger and the physical work out completely drained me pounding headache the lot lol
Honestly never again 😐😐
did a dpf on a 1 series and thats a pain. but looks hell of a easier job compaired to this one
Did the new intake manifold make much difference?/ was it expensive? Been debating doing it to my 325d e91
I’ve had diesel BMW’s since 2005. An e60 535d until 2011 (then sold it to a friend who ran it until 2018 without issue) An f10 520d until 2016 & currently running a f31 335d touring for the past nearly 6 years. Not once has the DPF, EGR or anything in the emissions system ever given a problem. The f31 has just had it’s egr cooler recall done to be fair but that’s the only inconvenience it’s caused me regarding emissions.
As far as I’m concerned, use quality premium fuel, change the oil regularly & make sure to give it a good motorway blast at least once a month is the key.
Yes I give mine the Italian tune up. I give it a good run at 80 mph for a good couple of hours.
Man u keep up the good work. Your videos are always helpful. Thanks.
Appreciate it!
Mk4 321k miles on same DPF and still going strong !!!!!
DPF been lots of problems but additives would sort it out .
Did the DPF, egr and the swirl flaps (just in case) too, along with a map. Standard practice.
Never bad practice!
Such a timely video for me 😅 I've been agonising over getting the DPF of my 2006 330d off for a good clean (back pressure over twice the permissable values). Regen had stopped due to bad thermostat, glow plug faults and possibly because ECU had expired the DPF due to having run for over 160k miles.
With the stats, plugs and controller replaced, the car was still refusing to regen due to 480A and 481A fault codes (as stated in ISTA when requesting regen). I thought I'd try the DPF cleaning foam route down through the back pressure sensor tube as I really didn't want to start another big job and happy to say it actually worked.
After one can the values dropped just shy of permissable values, meaning regen still couldn't run, but the next day I run another can through and got it well into regen range. Due to the lower back pressure, I was then able to tell the ECU the filter had been replaced and request regen. On the next drive, the second the car got up to temp, regen started when I was only going 30mph and was even running at traffic lights. Temp really increased once I got to 40mph and back pressure plummeted down to next to nothing.
Hope this helps someone 🙂
Which can of Dpf cleaner did you use please.
My ‘06 e91 330d had similar issues last year with cool running thermostat not allowing regen to start. Since thermostat and glowplugs etc replaced, It regens ok now but does it alot so fancy trying a can but not sure which one to try…. Cheers,
Dave.
Great Channel by the way George A.
@D S E91, just like mine 😁 I used "POWATEC DPF / CAT CLEANER + FEED PIPE" from GSF Car Parts. Used two cans, applied separately a day apart. Each time it knocked off about 40-45mbar of back pressure at idle.
If mine was a bit less blocked and reneging still, i might have tried a fuel additive first. Powatec do one called DPF SUPER CLEAN also available at GSF. TBH I'm sure most other brands are just as effective.
My B.P is 1500 on ista!.
So reading your comment, I'm assuming a regen is blocked pending removal, cleaning and reset
@Gu Lag Wow that's high! Is that 1500Mbar at max RPM? Mine was around 500mbar at the highest reading.
But yeah, your plan of action sounds good to me. Just look out for any reappearing fault codes that may prevent future regens like what I had with the glow plugs and thermostat.
wow! sorry which foam cleaner did you use and where did you put it? thankyou!
I feel your pain mate.. I've spent a whole day trying to get my DPF out my F30 N57. Bolts are impossible to reach, cut my hands 1000 times. Trolley jack failed while it was holding up my engine hahaha!! I've got big problems to solve tomorrow. FML.
Oh wow.. Good luck lol
George honestly you are fighter.But biggest mistake that people do with BMW diesels is not letting regen do it's thing.Every couple weeks drive on the open highway for about 30 to 40 minutes does miracle for the car.They are really not city cars for 15 to 20 min.ride.I have E70 with 220k(miles) with original dpf and still running great.Changing an oil every 4-5 k and glow plugs is absolutely essential.But gutted dpf is not bad thing either.Cheers.
I'm doing this job on my E91 330D Xdrive. It's a big pain in the ass , but doable with a engine support like you got there and dropping the sub frame a little bit indeed. Doable alone,but recommend someone when you need to get the subframe down more using a pry bar or something. The only thing i struggle with really , is that engine mount bracket... Removing was EASY. But reinstalling is another thing... Shops they quote you good money because it takes much longer then removing it from a NON xdrive model.
i have my egr on my mondeo mk4 blanked out now for about 4 years with no problems but now its stuck open so im getting it mapped out, the guy said i dont have to actually remove it that mapping it out would be enough what do you think? is there any point removing it if its mapped out and blanked?
Got stuck with the motor mount found the answer here! Thanks for the video! Turbo replacement. 😔
I have a turbo replacement video coming soon👍🏻
Love u man. Thanks for every video u post
You are making some excellent videos. You are very intelligent and articulate. I have a couple of questions: 1. What do you mean by "remapped" and 2. What do you mean by deleted? Do you have a video that explains these things? Who can do it? What does it cost? Thanks
Hello mate, would you be able to tell me where the exhaust has temperature sensor bank 1 circuit 1 is located please on a e90 m57 330d
Hey George - my good friend has removed the old dpf and replaced it with a new dpf. It’s installed, no dpf lights now, it’s regenerating, but it has a chemically smell now for the last 3 weeks driving everyday. Any suggestions as to what it could be?
Seems a hell lot of work for you mate. I can tell it was big hassle and learning curve for any X5 owners from that series. My 2008 E65 730d still got DPF in I got it taken off around 125K and soaked in liquid for 2 days and car felt like new. Since I use forte DPF cleaner and regenerator every 6 months and change oil 5K and no issues and now on 210K. I only leave it on as don’t want it to smell like an old diesel. Keep up the good work mate
Yeah it's all personal preference.. My mate didn't want to map his car once then decide then have to map it again once the DPF fails
@@GeorgeAusters my 1 series will not regen due to glow plug issue and preheater issue. i take it theres no need to map it out after “cleaning”. nippy little thing after the “clean”
@DEVILS cousin Once DPF is cleaned, clear the fault codes and depending on mileage, you may need to mark DPF as replaced (think they have a predefined expiry of 250k ish km).
Providing there aren't any reoccurring fault codes like glow plug, throttle valve, 480A/481A and engine gets up to temp ok, active regen should be able to run when required. Without the above sorted, the DPF will likely gradually block up again, unless you take regular longer/higher speed trips to allow passive regen.
This is all explained in far greater detail in ISTA D.
Can you change my pdf 😅
@@devilscousin4643 I believe once it is "cleaned" it still needs to be coded out. Get the glow plugs and relay changed then it will regen.
I have a 330d e91 2008 i have done the same,remap doing 294 bhp and 510 torque,only draw back is the smell of diesel when stationary 🤔
I too disagree with the removal. I commute from San Antonio to Austin daily and it works well. The motor isn’t set up for frequent start and stops and just trips to the store. Once rolling down the highway, the system works as it’s designed.
My 218D Msport coupe 2018 is at 130k now and i do 100miles plus per day in town, Might be stupid to ask if the dpf is clogged but i got error code P0138 bank 1 sensor 2 high voltage, am i best to just delete/gut the dpf? will i need these sensors or does the guy deleting/gutting know what to do, very stressed as my engine light is on with reduced power and i need the car daily.
Nice one dude, very explanatory information.... Nice one 👍
Most obvious clue with gutted dpf is the sound difference , smart people send a core drill through so it’s as quiet as stock
Oxford number plate 😃👍🏼👍🏼👍🏼
200,000 miles now no signs of any problems ?? BMW e92
Well done George! What if you had a quicklift, would you do it again?
Even a quick lift only lifts the car up so far 😅
How about a proper old school mechanics pit you drive the car over for the work?
I’m a mechanic & only drive petrol Japanese cars.
Probably for reasons the same as a gynaecologist not liking cunnilingus.
We see these systems at their worst.
Great video & very informative George, I was considering having the DPF & EGR removed from my 2015 F15 40d, any advice ?
Ask for some quotes at garages👍🏻
@@GeorgeAusters bizzarly enough i have just received a letter from BMW Group saying the following ….
‘Advanced Notice Of A Vehicle Safety Recall’
Exhaust Gas Recirculation (EGR) Replacement.
Would i be best just getting the EGR replaced free of charge & having the DPF delete at a later date by my independent ?
Also do you have any more advice on the F15 N57 engine ?
Regards
That will be the EGR cooler, its common for it to crack.
Watch my N47/N57 engine common problems video
Would you recommend doing an EGR delete as well?
Yep!
Hi George, have you heard of SULNOX ? regards Bill
Will this improve fuel consumption? Mine is running 16mpg in town…. I’ve done long runs to try and regenerate but no difference.
For sure!
evening champ, need your EXPERT advice, my N47 2.0 diesel is making an AWFUL noise , sound`s like the bottom end to me, but when the timing chain was changed (new one) the previous owner put a 2nd hand crank pulley on it, somebody suggested to me that the bearing in that could have gone, making the noise, does that sound likely to you , champ 🙄🙄
I'd replace the pulley regardless, watch my crankshaft pulley replacement video and I have linked the one I recommend there
@@GeorgeAusters cheers champ
did you leave the SCR? it wont clog? how's the smell after this?
There is no SCR on this👍🏻
@@GeorgeAusters so how had is the smell?
Not a chance in hell that will go through a properly carried out emissions test
It's a grey area really as in the MOT Guide it states that... " If a diesel particulate filter has clearly been cut open and rewelded, you should reject it unless the vehicle presenter can show evidence that there was a valid reason to cut it open, such as for filter cleaning." So in therory if the DPF less vehicle meets the MOT set emmision requirements and doesn't produce excessive smoke during the test then the "vehicle presenter" aka the owner of the vehicle can just say (prior to the MOT test ) ... BTW or FYI , my DPF has been cut open for cleaning purposes ;-) ... and "in theory" that should be enought to pass.
It will pass fine no issue!! Clueless. If the MOT tester cant see the downpipe then its fine which they wont be able too as undertray be in the way
@@scott2495 Correct, I ripped the thing out completely and straight piped it, on an E70 it's buried at the side of the engine so can't be seen under normal conditions. has been through three NCT's (Irish MOT) no problem at all. To say the turbo was liberated is an understatement.
Mine does and has no egr present either 🤣
@@pjmccracken Where did you get it re-mapped
Good luck with next MOT emissions test
Will pass easy. Never had 1 fail
Hi mate I have a vw Passat 2.0tdi, I want to remove the dpf,can I remove it without messing about with the computer.
Needs to be mapped out
is it easier to remove the dpf from a e82?
Yes
My 1991 Mercedes 208d has non of this shit on it and it never breaks down.
When Diesel engines were bullet proof!
You need a lift and an engine bar like you used . Bc dropping the front suspension holder is really needed . I used to be the fastest @ BMW for this job . It becomes alot more easy if you loosen the subframe bolts 😅. But yeah its a bitc to do it like that on your driveway
Yep really not fun without a lift!
2:00 @GeorgeAusters I can’t find the link to the cleaning video. I’m trying to confirm if mine was cleaned properly. Can you point me to the link please
Cleaning what?
@@GeorgeAusters the dpf
@OCDan1 Here you go:
czcams.com/video/v2vCtKWon_0/video.html
Haha share the pain as I have had the DPF on and off my 330d a few times and that engine mount is a pain in the arse!! Personally I would never advise to remove a DPF, instead get the problems fixed that contribute to a blocked DPF like thermostats and more regular lengthy journeys.
Plenty of things that can fail on the DPF like pressure sensors etc too though!
This engine does a good job of cleaning itself but a lack of understanding (and a very odd fault code logic) means the owner does not know there is a problem until the piwer vanishes! All of the glow plugs must operate, and the car always have at least a quarter tank of fuel or the DPF will not regen. Once these preconditions are met, the self cleaning cycle works really well. I have had them with back pressure so high (1000mb plus) that the car reports a faulty pressure sensor. Forcing an active regeneration and a hard drive will bring the back pressure down to zero and restore the power.
@@elliottpeters2996 Yes agreed I have fault code 480A but nothing on the dash. Stats and DPF are new so I give up and will drive it until it stops!! I also note when the car is doing an active regen the temp only gets to 460c which is not enough to burn the soot?
@Dazzlers Channel Yeah active regen temps are generally higher when combine with driving. If you're seeing either of the 480A/481A codes, that signifies regen isn't running. If the DPF is new and you haven't got any other related fault codes, sounds like you might just need to mark the DPF as replaced. I believe you need to clear fault codes in order to reset and can only be done if backpressure is within permissible values.
Keep the DPF, keep the EGR, but remove swirl-flaps if any. Just do a little extra maintenance (checking and cleaning the EGR and intake manifold every 5 years or so) and more frequent oil-changes, and the DPF and EGR will not be a big problem. Your consciousness will be clean as will the air leaving the exhaust, for the most part. I hate diesel cars without DPF, a sure sign is a huge black smoke filled with toxic particles coming from the exhaust, most notably when the accelerator is floored. Annoyance when it happens in the city and you are not yourself in a car with activated charcoal cabin air-filter.
DPF delete doesn’t mean instant black smoke on acceleration… that’s either due to shit car mapping or just a unhealthy engine with boost leaks, dodgy injectors etc.
The average owner doesn't want to keep removing items and cleaning them. Your engine will last much longer without any of the emissions devices!
Removing the EGR and DPF means they can NEVER fail!
Black smoke means too much fuel and not enough air (usually from clogged intake ports, caused by the EGR valve)
@@GeorgeAusters the engine might last longer, but not the people breathing the smoke
Dpf removal doesn't cause black smoke as already said.
The DPF cycle also uses extra fuel. Personally I would rather have it as I am slightly green in my thinking.
Yep.. Kind of false economy - You create more emissions by using more fuel!
@@GeorgeAusters Good point. But the extra emissions are mainly carbon dioxide while getting rid of some amount of soot particles. That's still a win in terms of respiratory health, though I don't know how significant.
Tyre particulates from heavy electric cars (all of them) produce more lung damaging particulates than the lastest DPF diesels. 🤔
Wait till you run the main bearings
@@gulag8735 I am not sure that's an issue on the old M57.
You don't even need to remove it to clean it, the Wurth DPF cleaner works great.
I saw someone use coca cola to clean it and it did a great job lol.
Yh but won't be long till problems rise again unless it wasn't that blocked in first place den your a lucky one
Anyone have fuel efficiency data post Delete ?
George you can get a DPF cleaned out, you do have to remove it but there are companies that have cleaning machines for DPF and you refit like almost new.
I will never ever be removing one of these again… I’d rather just gut it and forget it!
Isn't it illegal to remove a DPF.
Just drill it out lol
Has that dpf been gutted?.. looks very empty 😕
Just cleaned with hot soapy water
@@GeorgeAusters 😂😉
The problem with this is that the car sounds like a jet engine on any stage of the throttle. The turbo whistle is just too loud and annoying
Any garages that does this in UK ?
Just ask👍🏻
So why did it break down?
Video will be up this week!
Problem is that people buy diesels when their usage isn't really compatible. I can't agree removing emission controls is acceptable these days where air quality is such a hot topic. Buy the car and engine combination which suits your needs and you need to accept that replacement of dpf's and similar, could be part of the running costs. If replacement is likely but unaffordable (or justifiable), then its probably not the right car. Does the owner actually need a large diesel 4x4?
He needs a 7 seater and unfortunately this is the only BMW with 7 seats👍🏻
@@GeorgeAusters Fair enough. The problem we have is that diesel was pushed quite vigorously and petrol options are very limited on used cars over the last 10 years or so.
@@Mudster250 Yeah you're pretty much only left with the N62 V8 when it comes to petrol options which is an engine I wouldn't recommend to anyone
Where did LPG go? I remember dual fuel being a thing back in the day..
@@johnathanpearson3203 it's odd how LPG has disappeared. Running costs of a diesel (or better) and refinement and reliability of a petrol. Never had an LPG car, so maybe the aftermarket kits were unreliable themselves
had mine removed and left it to a garage and all done with all mapped out it was only £240 and done in a few hours
Yeah would definitely be easier on a lift and with multiple hands on it, and much nicer not rolling around in and cold and wet too
There’s no DPF or Cat in that down pipe 😅😂 you must of cleaned it so well it cleaned the DPF and cat away 😅👍🏽
Yep came up very well with a bit of hot soapy water!
@@GeorgeAusters what Happened the old Mr Muscle Oven done an Amazing Job breaking the particles down so when you put some of that Nice smelling fairy Liquid it cleans it so good, that you never have to deep clean It again wonderfull stuff indeed.
Why not just use a blocker instead of removing it?
Can I come working with you?
For us in northern europe, removing dpf, cats and other emissions control stuff is all cool and fun, until your yearly or bi-yearly roadsafety inspection date is up..
Your car will never pass inspection/emissions check without those systems in place and functioning properly, the new emissions analysing equipment will take every car that has been modded off the road, giving the owner the choice between putting everything back the way it was, or scrap the vehicle.
Offering services as a business removing or tampering with emissions stuff/software can get you in trouble with the law, sort of similar to what the EPA in America has been doing to all kinds of tuning shops, aftermarket (racing) parts suppliers and even big OEM factories.
I personally hate all the emissions crap fitted to post 1994 cars, cars from before 1994 have only very basic emissions control stuff on them and therefore have way less strict emission regulations to meet. but the pre 2005 diesels have been banned from a lot of major citys in an effort to improve air quality/reduce smog problems
No, you have to drive correctly the car and monitor the soot in the DPF and not interrupt the regenerations
If you wish to do that then you can of course!
Much easier and cheaper to get rid of it 👍
The best way to deal with dpf problems is to come away from Satan's fuel and get a petrol.
limp mode
Um, have two diesels, don't think either have one. 1990 Toyota Hiace 2004 Hyundai Terracan
Nope neither of those will have one. The 1990 might not even have a catalytic converter
@@GeorgeAusters Ok, great. Good for the next ten years or so at least then. I have 'some older cars, but they're petrol.
Is it just me who’s never had an issue with an EGR & DPF? Not worth the hassle to remove them for me.
You will soon trust me
My old 2002 astra 1.6 SOHC had a EGR problem at 80k. Replaced for £80 and no issues ran until 145k when I scrapped it. 😃
There are problems with all BMW DPF and DPF pressure switches. The DPF pressure switch fails which then makes the DPF not do a region
I would never have the balls to remove the DPF. I already got a taste of what unfiltered and raw exhaust fune exposoure does to my health over 6 months. Fatigue, muscle pain, random headaches, coughing for no reason, chest pains, shortness of breath, anxiety. You'd be insane to remove it. Nothing is more important than your health.
Do what you want with EGR but do not remove the DPF! It is dangerous to yourself and to everyone close to your car
pfizer?
OMG. Is it really that dangerous?! Haha
Some people took experimental drugs that cause issues in 1 in 35 according to reports.
Those who took it are the same people who worry about diesels. The same diesels that were around without DPFs.
I’d take no DPF on my car than any government advice.
Buy a petrol, simples x
Will not pass another not with our or any signs of tampering
No signs of tampering when it’s gutted👍🏻
If dpf gutted e.m light will on , no not !
@@andrewcitizennotsubject8897 if its done properly then no there won't be any lights on dash 👍
So, MOT failure then as the DPF is now gutted?
Depends on the readings the mot tester gets when testing the exhaust. But as mentioned in the video im going to assume it depends on the overall condition of the engine and how efficiently it can burn the fuel.
the way this was done it will not be obvious to a tester, BUT the emissions test may be hard to pass depending on year and sticker limits.
Nope.. Should pass fine!
George cleaned mine a few years back now, passed MOT every time not even a advisory 👍
Glad to hear Mark!
Remove the dpf get rid wast of time
This is bad advice since MOT will in near future start checking if cars have dpf removed...
No way to check
@@GeorgeAusters if mot legislation says there will be a check to see if the dpf has been removed then you can bet your life there will be a certified way to check probably using an electronic method. Also removing the dpf is already illegal.
@@GeorgeAusters Do they not test emissions in the UK? I thought the dpf significantly lowered emissions.
@@Veroxzes they reduce particulate matter , if you drive it hard now and then and deisel system healthy you wont get particulate matter to fail test, discovery 25 td5 no dpf passed all test
It's not removed, it's just not available anymore 🙂
I dont get what he has done, just see him standing there talking!!!
My n57 is on 250k and still on the factory dpf 🥴🤣
mine 310k
Make the car 🚗 performance better without it and save more ⛽️
So what you are saying is, if my car works perfectly fine i should just remove it because its going to fail some time in the future?
Thats the most stupid statement i have ever heard. You dont need to remove anyything if everything works, this is a totally clickbait title. If its clogged up, you will have to do something ofcours but judging by the title of this video i need to remove it immediantly.
But the EGR i would remove non the less, as it just makes a mess and clogs the intake. But removing the dpf just for the hell of doesnt make any sense. Unless you are tuning the hell out of it.
Simply don't buy a modern diesel
Can i just point out that modifying emissions equipment on your car is very illegal and also will cause your car to fail MOT. Fix it properly and get the dpf cleaned and maintain when needed BMW put it there for a reason!
Euro5 was the reason.
That's why I have a petrol diesel is dog piss
Removing your DPF is illegal and your vehicle can be taken from you and crushed. Not to mention it will never pass an MOT smoke test, and if it somehow does it will fail because it's been tampered with or is missing. Instead just drive your car properly and don't use cheap fuel an oil, problem solved 👍🏻
You don't know what your talking about 🤣🤣
@@adamswindells2310 Why don't I? I wok for VOSA which is the governing body for MOT testing. Go on the online MOT inspection manual and you will see it all on there?

@Lewis Jenkins vosa hasn't exist since 2014. You live your fantasy
Totally disagree with removing emissions stuff from cars.
Why? They use less fuel, last longer, take less service work. Less Carbon build up. Also drops the manifold temperature which is a big plus for longevity.
Must be a mechanic at kwik fit 😂
I used be of this opinion but I'm sick of multiple systems preventing dpf regeneration. Glow plugs, glow plug module, diesel quantity in tank, short trips, fuel pressure-sensors, pump, power fluctuations, coolant temp, coolant sensors, thermostat........the list is endless.......and then, to top it all off, if the regen is interupted, the extra diesel used to increase rail pressure is tipped into the engines sump......🤯
Cry more.
I agree. Diesel has 2 major problems ito emissions: NOx and particulate matter. Diesel exhaust fumes are a L1 carcinogen, and all these measures are designed to reduce the NOx and particulate emissions, which we inhale.
I'm fond of diesel engines (I'm a mech engineer and Bosch certified Fuel injection tech) and I think the tech on these machines are for a good cause. Removing dpf and NOx reduction equipment is injurious to your health.
Removing the emissions control gubbins is a question of ethics. Would you accept me urinating in your drinking water? Well, your removal of this kit is the equivalent to all of us breathing in your fumes, including you and your kids....
The right thing is almost never the easy thing. Which will you choose?
