@@adammcallister2260 I can assure you that has nothing to do with it, from the beginning of my channel i average 1 video a month and has never changed. Sometimes especially during summer vacation it might take a little longer.
I had exactly the same thing on a BMW X3 I bought cheap. Local mobile mechanic replaced DPF, it blocked again so old owner took it to the main dealer who said the turbo was dead and the head needed a lot of work. I found the hole, cut off the retaining band where it mounted to a hard pipe and pushed it on another 25mm. New Miclaor clamp and it was as good as new. The boost pipe had been rubbing on the coolant fan for some time.
Great job. Your diagnostic approach - determine what's wrong as well as what caused it and not just fix what may be broken - is outstanding. Truly the sign of a professional and someone who is customer focused. Thanks for sharing the video. Once again, Dan not only diagnosed it but also provided important educational advice. Looking forward to your next video.
I'm surprised there wasn't a boost pressure code. My bet is that issue was there before the previous dpf failed and forced regens with too much soot in the old dpf cracked it. Cleaning is always better than forcing a regen when the pressure is too high! Sometimes people reset the learned soot values to make the vehicle regen when in reality it shouldn't be doing.
Drivability parameters should have been checked before and after DPF replacement. Why is this engine running inefficiently? It should have been addressed before sending it down the road
Came here to say this. There was one as he stated because he disconnected the maf, I wonder if it was missed while focusing on the dpf pressure and cleaning procedure.

As an aviation mechanic , it was very refreshing to see an auto technician use a logical approach to diagnosing the cause of a problem and not just the symptoms. I do have a question for you though. Why did you not look for TSB's on the symptoms before you started all the troubleshooting? It seems that checking for the TSB first could have helped you reach the solution faster.
You still need to diagnose the cause. Proper diagnostic procedures is the most important step for a successful repair and should always be your first step of the repair procedure. Cars are not like airplanes. Every system in a modern car is computer controlled
@@deerhunter8533 I wasn't suggesting that you shouldn't have done all the other steps to verify that the problem the TSB indicated as the most likely root cause was indeed correct. Especially the cleaning of the DPF system and verifying the pressure sensor was operating within parameters. I was just curious about the order in which you did them. Cars are more like modern aircraft than you realize. For instance the F-22 Raptor can tell the mechanic that there is high iron and nickel content in the engine oil which is a precursor to bearing failure. Not to mention the various other sensors for coolant levels, fuel , hydraulic oil levels, etc..even the length of time a relay takes to activate all are monitored by multiple redundant computer systems.
In my day to day work checking for tsb's would be the first step of my diagnosis. But for TH-cam i like to show as much as possible of the diagnostic process. In this video i did a little of both.
a very useful tool for turbo engines is the smoke machine. so many dpf issues are due to cracked hoses, leaking injector seals at the rocker cover, etc. we got one recently after watching @Orileysautos videos, and it has really saved us hours of leak testing.
If you use a smoke machine on turbo systems make sure you use one that can generate enough pressure. Some turbo hoses only start leaking when boost pressure is applied

What a difference in service compared to Australian dealership. My Mitsubishi Triton MQ 2015 2.4L 4N15 my RPM is dropping b 625rpm every time I come to a stop and then quickly comes up to normal rpm 650. Same when idling with AC on, AC clicks in rpm goes up, AC clicks again rpm drops to 625 an then quickly goes up to 650. I have no trouble codes, tested all seniors all good. I bought a smoke machine to test for vacuum leaks and found that the EGR has a leak at the hole used for atmospheric pressure to allow the diaphragm to go up and down. Tested the EGR with vacuum tool and it does hold pressure but has a leak when test from the intake. Purchased new EGR, and had the same leak, ordered another and the same leak. So bit the bullet and booked it with the dealer$hit and I told them what needed to be fixed and that the car has no trouble codes, they said diagnostics are done on a Thursday. Went to the dealership and sat there for half a day but they only looked at car for 15 minutes. Result was it has no trouble codes but we updated the computer, that will be $200 thanks, paid the bill got into the car only to find the same problem. When back in and told them it's still doing the same thing, they said maybe it could be the EGR or valve adjustment, the quote was $1850. Not paying $1850 for a maybe. Can anybody confirm if the EGR leak is normal as I can't get a confirmation from any dealer and the internet has mixed reviews. My EGR has vacuum operation and electronic built into the same unit. Thanks
His car has other faults he dosent want fixing , his front windscreen is cracked 😂😂, droving it with that faulty , obviously dosent want to spend his hard earned cash as they say 😂😂😂, hope you charged him and he watches this video to show how honest you are Dan , many would have charged for a smoke test
You know Jimmy o reiley has already watched this! This had his name all over it! Can't believe it didn't throw a turbo under boost fault up or MAF correlation code up. That was a big spilt!. Another great video. Putting the point across that dpf only block up because of an underlying issue
I thought the same but a diesel jag I had showed no fault codes it was barely running,smoke from rocker cover and dipstick I thought the engine had gone but no I smoke tested it to find out a intercooler hose had rotted jubilee clip and the hose came off,put new one on it’s like new now but still you would have thought it would show a fault but it didn’t 😂
My add to the video. I have one Honda C-RV 2008 2.2 diesel that had the exact fault. The difference were tha I have a manual 6 speed gearbox. I left it to my repair shop and they told me"We can not regenerate DPF because AC is not working". My thaught on that answer, These two are different systems to each other butI learnd that tha engine computer controled both systems together and I had onf faulty ac-compressor. I had to change compressor and air-dryer filter and fill everything back up again to be able to regenerate DPF. When done, my car is fixed.
Your methodical diagnostic approach is outstanding. Really enjoy your channel. Just wish you would put out videos more frequently. That way I could become smarter faster 😊
Excellent job Dan, with this scenario u'd think the owner would've noticed a performance drop sometime before but I think that's just indicative of his driving style.
Nice video, congrats for being honest with the work. It is very good you did not replace again the dpf, but, instead, you looked for the cause that lead to dpf clogging. Also for the customer, it is cheaper to replace one broken (and in-sight) hose, than pay 2 dpf's and labour
Excellent job , and very good described 😉👌🏻.... Owns a Volvo V60 T6 R AWD, 326 hp from 2020 , my ever best car in my opinion.... Love it ❤❤ But as an old retired mechanic myself it was an excellent video of good diagnose and repair. Thx and keep up the good work 💪💪👏👏
Great Diagnose Dan: As an Automotive TAFE Teacher, I told all my students: Before you reach for the scan tool, LOOK AND LISTEN, UNPLUG AND REPLUG CONNECTORS. It is amazing how many times this fixes an Issue, finding the CAUSE ,as you state.
Unplugging connectors before reading faultcodes is not the best of advise in my opinion. Unplugging connectors could set faultcodes that have nothing to do with the cars issue and send you down a Rabbit Hole.
Almost 99% of dpf problems on vehicles are either caused but turbo issues or boost pipes being burst. See this kinda fault a lot on Mercedes with the 651 engine.Either than that it’s always cars that are city driven and can’t regenerate . Great content as always Sir.
@@mosestaukobong5937 that's not my experience we see many different causes for dpf issues. It can be; behavior of the customer (short trips) an engine that uses oil, injector issues, egr issues, temperature sensors failing, AdBlue injectors stuck open, turbo issues, mass airflow sensors, failing pressure differential sensors, and i could keep on going.
Nice to see the filter is working so good and that the particles are for real! Some also get clogged by short city driving, the conditions for regen are never met. A petrol is less problematic if mostly city/short driving..
Dan, your customers must be very lucky people - thanks to your experience and systematic approach they save lots of time and money! And, I used to repair starter motors and alternators for about 10 years and the soot, mixed with engine oil, would never leave my fingers🙂- I had no time to put the rubber gloves on 😁
Thank you for understanding dpfs. There are so many mechanics that just don't understand how a dpf works and it drives me nuts. "Dpf clogged? Yeah just replace it" ahhhhhhhh
One of the most common causes I've found of dpf high frequency regeneration is the intake pipe leak.... experience has came to find usually the pipes split when the dpf gets blocked to the point the car struggles to start or doesn't and the back pressure and intake pressure meet and blow out. Often tend to find the dpfs block up due to oil leaking from the turbos, which is typically caused by poor and infrequent oil changes is usually the biggest cause of them blocking up..... always great to have ddtsb though dan.... like in terms of precisely.... I now carry digital weighing scales in my van.... thats the level we are at.... cheers. Felix
Looks like Dan spent a couple of hours on the fix and, to my mind, it wasn't a 'come back' job but I know from my time in the business that the customer will say it is and that the Service manager will write off the bill as a goodwill gesture. That cost would then be deducted from my bonus at the months end and this is one of the reasons I retrained and left the motor industry. Best decision I ever made as, for the first time, I could afford to buy and run new cars rather than patching up other peoples cast offs.
I have connected an indicator light to the rear window defroster. During regeneration the light comes on and I continue driving until it goes out. This way I have a complete regeneration in one go. This takes 10 minutes. This is a very useful solution for those who drive short journeys. I do this on Stellantis (PSA) cars. I don't know whether other brands also switch on the rear window heating during regeneration. Stellantis diesels use an additive 'Eolys) to lower the regeneration temperature. From this I conclude that other brands that work without Eolys also switch on the rear window heating to achieve the desired exhaust gas temperature.
😊😊😊😊 thank you very much for another wonderful video. Thank you very much for your time and effort for putting it all together 10 out of 10. The diesel market in the diesel community is finally catching up with all of the extra cats and everything else that are put on all the cars and the trucks and everything else and now all the little problems are now finally showing their ugly little heads and all the codes to come with it and everything goes in limp mode. If you get stuck out on the road, you’re kind of like upper creek without a paddle going nowhere thank you again Dan.
I had one of these as a roadside breakdown. Found the split hose and used Amalgamation tape as a temporary repair. Dan, I think viewers might miss what you say about a cracked dpf. It's a internal crack not a crack like a fractured weld etc letting exhaust gasses out the side of it. Wonder if the hose caused the original dpf to crack??
Hose cracked because of deterioration of the rubber material, oil does that to rubber. DPF can crack because of age, temperature or low quality material
@@deuce9769no, DPF cracking is a result of excessive soot load during regeneration - i.e. someone reset the soot loading when the DPF light came on, then continued driving until the vehicle finally managed to do a regeneration - at which point the DPF was already overloaded. This causes excessive temperatures inside the DPF (can easily exceed 1300⁰C instead of the normal
When I was stationed in California, back in the 70s, mandatory emission testing was required. Waving the wand in the air would fail the test. Put it in the tailpipe, and it would pass. The smog was so bad, the engine was cleaning the air.
Glad to see you back again. This was a very interesting problem which you fixed by instituting "cause and effect" (or effect and cause) protocol. I'm retired now but in my trade, electronics, this worked as well. Thank you,
I’m glad you brought up the all cars are made the same and if one part fails it will fail on every other car made people don’t usually understand that one.
Someone mentioned smoke testing. I agree. Mitsubishi Outla Der diesel. Is the diesel better or worse than the gas model. Any Mitsubishi technicians out there? Diagnose Dan is one of the best, if not the best diagnostic technicians on TH-cam.
I would love to hear your comment on this: I drive a Opel Corsa pick up at work. This thing started to do a strange thing. When driving with lights off, all was normal. With lights on, and using right hand turn signal, the high beams would go on. A small wiggle of the stalk would most times correct that, but not every time. Every now and then, I would have no lights, and only the rear turn signals would work. Trying to turn on the lights would only show the blue high beam lamp and the green turn lamp on the dash. I thought (correctly, as it turns out) that I had a missing or bad earth connection. It took me several tries to find out that the battery negative lead to the body was bad. The nut on the clamp had vibrated loose, so the body earth was intermittent. The clamp itself was tight, hence never a starting or charging problem. Why would the rear turn signals work but not front? And best of all, why would the high beams go on only when turning right? Weird!
whenever there's something wrong with my car, I always check online forums or TSBs to see if anyone else is having the same issue. 90% of the time, someone else is having the exact same issue. :) I do that before getting my hands dirty with the repairs... :) saves time that way.
You are the best in troubleshooting, this is my personal opinion,.You are very pleasant person and admirable tutor. I wish you good luck and I devine you flawless health as you do to the cars
Thank you so much Dan for this very informative Video. Thanks Dan to encourage us mechanics to dig deeper in finding the cause of a problem on the car for a permanent fix or repair. I love the Video thank for teaching us Dan ! Greetings to your entire family Dan 😀
The qualitybofnyour videoes are a treat Dan! 👍👍👍 I had a split hose on my 2008 Golf 1.9TDI.. it was producing a cloud of black smoke upon acceleration. It barely passed emission test last year and this year after repair, it passed with flying colours. 😊
Brilliant video as always.......! Thank you for sharing your wisdom with us for free. It's an amazingly complicated system with so many possibilities. If I was a younger person, I would volunteer to work in your shop for free, just to learn some of your many secrets. Thanks again Professor...!!
Hi Diagnose Dan, trust you are super well... love watching your videos.. I have an issue with my car - VW Tiguan 2020 TSI. I have checked with numerous VW dealers and other Mechanics and still no one can find an issue. In the morning on cold start when turning left at a stop has a noise that sounds like metal that is loose / dragging. As I said you here this when the car is at a stop then taking a left. I have not heard anything when the car is turning right. The noise is more prominent when turning left up a hill. Shocks, struts, bearings, links and sway bars have been checked. Nobody can find any issue. This is only heard in the early mornings on cold start...
I think everyone in Australia who has a Pajero Sport buys aftermarket silicone intercooler hoses because splitting is such a well-known issue. I would love to see the original DPF because I reckon the problem was the split intercooler hose the whole time.
I have seen this like a hundred times. (KIA & Mitsubishi tech) As soon i saw the codes i knew that the hose would be the cause 😊. I have only used the original M.U.T diag tool and i have always been able to force an regen.
I usually look at MAF and Turbo pressure, if I have good MAF and lower than usual boost pressure that means the air is metered and escapes between the turbo and intake. A leak and as this is already metered with the MAF the ECU gives fuel for that metered air, but the engine in reality does not get that air so we get rich mixture (black smoke).
in my country the technicians don't bother with diagnostics the reason they just fix the results and make money:( and if you find a mechanic like Dan you are lucky. thx for video
I like your test drive area. Very nice! That's great you had that bulletin. It helped show the damaged hose. (Not Enough Air) I started to think blocked air filter or air inlet, but without a Mass Airflow Sensor reading, it makes the diagnosis more difficult. Great video! Hope the customer was happy. Also if this is a "pattern problem," I hope the OEM has an updated fix.

Here in NSW, Australia, that windscreen crack/s would instantly fail a registration inspection, especially as it's right in front of the driver!
You know Jimmy o reiley has already watched this! This had his name all over it! Can't believe it didn't throw a turbo under boost fault up or MAF correlation code up. That was a big spilt!. Another great video. Putting the point across that dpf only block up because of an underlying issue
I thought the same but a diesel jag I had showed no fault codes it was barely running,smoke from rocker cover and dipstick I thought the engine had gone but no I smoke tested it to find out a intercooler hose had rotted jubilee clip and the hose came off,put new one on it’s like new now but still you would have thought it would show a fault but it didn’t 😂
I've seen some of his videos and he seems to be dealing with alot of dpf stuff!
Fantastic work Dan, Always a pleasure watching
Thanks!
My add to the video. I have one Honda C-RV 2008 2.2 diesel that had the exact fault. The difference were tha I have a manual 6 speed gearbox. I left it to my repair shop and they told me"We can not regenerate DPF because AC is not working". My thaught on that answer, These two are different systems to each other butI learnd that tha engine computer controled both systems together and I had onf faulty ac-compressor. I had to change compressor and air-dryer filter and fill everything back up again to be able to regenerate DPF. When done, my car is fixed.
I too want a diesel Mitsubishi. Love diesels
This is why we keep missing you Dan,please come often,you keep us waiting for so long friend
Thanks for your comment its appreciated
Your methodical diagnostic approach is outstanding. Really enjoy your channel. Just wish you would put out videos more frequently. That way I could become smarter faster 😊
🤣 🤣
Excellent job Dan, with this scenario u'd think the owner would've noticed a performance drop sometime before but I think that's just indicative of his driving style.
Nice video, congrats for being honest with the work. It is very good you did not replace again the dpf, but, instead, you looked for the cause that lead to dpf clogging. Also for the customer, it is cheaper to replace one broken (and in-sight) hose, than pay 2 dpf's and labour
If the Dpf would have been broken that would have been covered under warranty including labour.
Excellent job , and very good described 😉👌🏻.... Owns a Volvo V60 T6 R AWD, 326 hp from 2020 , my ever best car in my opinion.... Love it ❤❤
But as an old retired mechanic myself it was an excellent video of good diagnose and repair. Thx and keep up the good work 💪💪👏👏
Great Diagnose Dan: As an Automotive TAFE Teacher, I told all my students: Before you reach for the scan tool, LOOK AND LISTEN, UNPLUG AND REPLUG CONNECTORS. It is amazing how many times this fixes an Issue, finding the CAUSE ,as you state.
Unplugging connectors before reading faultcodes is not the best of advise in my opinion. Unplugging connectors could set faultcodes that have nothing to do with the cars issue and send you down a Rabbit Hole.
Visual inspection only. Do not touch anything. If problem is intermittent, and you accidently fixed it, you never know what was the problem.
I'm glad Dan "we fix it again" 😅🍻
The customer is always right *in matters of taste. That* is the quote.
Almost 99% of dpf problems on vehicles are either caused but turbo issues or boost pipes being burst. See this kinda fault a lot on Mercedes with the 651 engine.Either than that it’s always cars that are city driven and can’t regenerate . Great content as always Sir.
@@mosestaukobong5937 that's not my experience we see many different causes for dpf issues. It can be; behavior of the customer (short trips) an engine that uses oil, injector issues, egr issues, temperature sensors failing, AdBlue injectors stuck open, turbo issues, mass airflow sensors, failing pressure differential sensors, and i could keep on going.
Nice to see the filter is working so good and that the particles are for real! Some also get clogged by short city driving, the conditions for regen are never met. A petrol is less problematic if mostly city/short driving..
The particulate counter is a real eye opener.
Dan, your customers must be very lucky people - thanks to your experience and systematic approach they save lots of time and money!
And, I used to repair starter motors and alternators for about 10 years and the soot, mixed with engine oil, would never leave my fingers🙂- I had no time to put the rubber gloves on 😁
Somehow rubber gloves dont work for me either, they tear each time i touch something
Thank you for understanding dpfs. There are so many mechanics that just don't understand how a dpf works and it drives me nuts. "Dpf clogged? Yeah just replace it" ahhhhhhhh
One of the most common causes I've found of dpf high frequency regeneration is the intake pipe leak.... experience has came to find usually the pipes split when the dpf gets blocked to the point the car struggles to start or doesn't and the back pressure and intake pressure meet and blow out. Often tend to find the dpfs block up due to oil leaking from the turbos, which is typically caused by poor and infrequent oil changes is usually the biggest cause of them blocking up..... always great to have ddtsb though dan.... like in terms of precisely.... I now carry digital weighing scales in my van.... thats the level we are at.... cheers. Felix
Also the use of low SAPS oil is highly recommended in engines that have exhaust gas treatment systems.
Thanks for your comment Felix!
Looks like Dan spent a couple of hours on the fix and, to my mind, it wasn't a 'come back' job but I know from my time in the business that the customer will say it is and that the Service manager will write off the bill as a goodwill gesture. That cost would then be deducted from my bonus at the months end and this is one of the reasons I retrained and left the motor industry. Best decision I ever made as, for the first time, I could afford to buy and run new cars rather than patching up other peoples cast offs.
I have connected an indicator light to the rear window defroster. During regeneration the light comes on and I continue driving until it goes out. This way I have a complete regeneration in one go. This takes 10 minutes. This is a very useful solution for those who drive short journeys. I do this on Stellantis (PSA) cars. I don't know whether other brands also switch on the rear window heating during regeneration. Stellantis diesels use an additive 'Eolys) to lower the regeneration temperature. From this I conclude that other brands that work without Eolys also switch on the rear window heating to achieve the desired exhaust gas temperature.
Video takes me back to diagnosing DPF issues on my old BMW E61! Nice work Dan.
I worked alot on that generation 5 series i even owned a 525 diesel although that was an E60 sedan.
😊😊😊😊 thank you very much for another wonderful video. Thank you very much for your time and effort for putting it all together 10 out of 10. The diesel market in the diesel community is finally catching up with all of the extra cats and everything else that are put on all the cars and the trucks and everything else and now all the little problems are now finally showing their ugly little heads and all the codes to come with it and everything goes in limp mode. If you get stuck out on the road, you’re kind of like upper creek without a paddle going nowhere thank you again Dan.
Thank you for your fantastic comment!
O'Riley's Autos the DPF King uses Launch DPF cleaner, I mention it because it is a single shot application and always seems to work.
It's been a while. Sure glad to see you back!
Thanks!
I had one of these as a roadside breakdown. Found the split hose and used Amalgamation tape as a temporary repair. Dan, I think viewers might miss what you say about a cracked dpf. It's a internal crack not a crack like a fractured weld etc letting exhaust gasses out the side of it. Wonder if the hose caused the original dpf to crack??
Hose cracked because of deterioration of the rubber material, oil does that to rubber. DPF can crack because of age, temperature or low quality material
@@deuce9769no, DPF cracking is a result of excessive soot load during regeneration - i.e. someone reset the soot loading when the DPF light came on, then continued driving until the vehicle finally managed to do a regeneration - at which point the DPF was already overloaded. This causes excessive temperatures inside the DPF (can easily exceed 1300⁰C instead of the normal
When I was stationed in California, back in the 70s, mandatory emission testing was required. Waving the wand in the air would fail the test. Put it in the tailpipe, and it would pass. The smog was so bad, the engine was cleaning the air.
This is such a great channel. Very clear, detailed explanations.
Glad to hear you like the videos!
I wish more people would perform the same thought process as your do.
Very good explanation why DPF is need to be in place and also why DPF destroyed by fat fuel mixture!
Not destroyed but blocked
well well, Dan is using my brand new scanner - im still learning my way around in there - Topdon Pheonix Max
@@jimmypeters-j9s its a great scantool!
Glad to see you back again. This was a very interesting problem which you fixed by instituting "cause and effect" (or effect and cause) protocol. I'm retired now but in my trade, electronics, this worked as well. Thank you,
Thanks for your comment!
Thorough and easy to understand. I love this guy.
Thank you!
Diagnose Dan is the Chuck Norris of the automotive world
I’m glad you brought up the all cars are made the same and if one part fails it will fail on every other car made people don’t usually understand that one.
You have so smooth roads there. Better roads in the industrial area compared to Finland main highways :D
Ps. Great work once again!
We also pay alot of tax for it😂
Another masterclass, have learned a lot about DPF and smoky diesels, many thanks!!
Thanks for your comment!
Car is never an unsolved problem !! Customers attitude is!! Thanks Dan
Its a pleasure!
I have a Mitsubishi ASX in Australia with same engine, good to see some tips and I’ll be checking my boost hose.
Someone mentioned smoke testing. I agree. Mitsubishi Outla Der diesel. Is the diesel better or worse than the gas model. Any Mitsubishi technicians out there? Diagnose Dan is one of the best, if not the best diagnostic technicians on TH-cam.
Shuddered when you lifted the engine cover after doing the timing chain and balance shaft unit on that engine but good video!
I would love to hear your comment on this: I drive a Opel Corsa pick up at work. This thing started to do a strange thing. When driving with lights off, all was normal. With lights on, and using right hand turn signal, the high beams would go on. A small wiggle of the stalk would most times correct that, but not every time. Every now and then, I would have no lights, and only the rear turn signals would work. Trying to turn on the lights would only show the blue high beam lamp and the green turn lamp on the dash. I thought (correctly, as it turns out) that I had a missing or bad earth connection. It took me several tries to find out that the battery negative lead to the body was bad. The nut on the clamp had vibrated loose, so the body earth was intermittent. The clamp itself was tight, hence never a starting or charging problem. Why would the rear turn signals work but not front? And best of all, why would the high beams go on only when turning right? Weird!
whenever there's something wrong with my car, I always check online forums or TSBs to see if anyone else is having the same issue. 90% of the time, someone else is having the exact same issue. :) I do that before getting my hands dirty with the repairs... :) saves time that way.
Not heard from you for a while. Always like the way you methodically go through the issues. Sorted and done yet again.😄👍
Thanks for watching!!
You are the best in troubleshooting, this is my personal opinion,.You are very pleasant person and admirable tutor. I wish you good luck and I devine you flawless health as you do to the cars
Thank you
Excellent video Dan. We don't drive too many diesel vehicles in the USA but I learned how sophisticated no gasoline engines can be.
Thank you Dan.
Thank you so much Dan for this very informative Video.
Thanks Dan to encourage us mechanics to dig deeper in finding the cause of a problem on the car for a permanent fix or repair.
I love the Video thank for teaching us Dan !
Greetings to your entire family Dan 😀
The tools Dan has are so good.
And so expensive i bet too.
Diagnosis means = split or unknown
Thank God we have DiagnoseDan
Thanks for watching
The qualitybofnyour videoes are a treat Dan! 👍👍👍
I had a split hose on my 2008 Golf 1.9TDI.. it was producing a cloud of black smoke upon acceleration. It barely passed emission test last year and this year after repair, it passed with flying colours. 😊
Thats great to hear!!
Brilliant video as always.......! Thank you for sharing your wisdom with us for free. It's an amazingly complicated system
with so many possibilities. If I was a younger person, I would volunteer to work in your shop for free, just to learn
some of your many secrets. Thanks again Professor...!!
And thank you for watching my videos and taking the time to leave a comment its really appreciated!
Hi Diagnose Dan, trust you are super well... love watching your videos.. I have an issue with my car - VW Tiguan 2020 TSI. I have checked with numerous VW dealers and other Mechanics and still no one can find an issue. In the morning on cold start when turning left at a stop has a noise that sounds like metal that is loose / dragging. As I said you here this when the car is at a stop then taking a left. I have not heard anything when the car is turning right. The noise is more prominent when turning left up a hill. Shocks, struts, bearings, links and sway bars have been checked. Nobody can find any issue. This is only heard in the early mornings on cold start...
I had that happen on my Scion, check the metal shield behind the rotor, it was slightly touching it, just push it back a little bit
Nice work, You should have put those Paddle shifters on that Diesel to the test! Agree more videos and bloopers needed.
😁👍
I think everyone in Australia who has a Pajero Sport buys aftermarket silicone intercooler hoses because splitting is such a well-known issue.
I would love to see the original DPF because I reckon the problem was the split intercooler hose the whole time.
Just returned from a trip to Holland lovely country clean and tidy place nice roads with plenty of road signs loved it
I hope you had a good time!
You are a real repairman!! Greetings from Sweden.
Thank you!
Another great study and example of your diagnostic process and confirmation of issues.
Thank you
I have seen this like a hundred times. (KIA & Mitsubishi tech) As soon i saw the codes i knew that the hose would be the cause 😊. I have only used the original M.U.T diag tool and i have always been able to force an regen.
I usually look at MAF and Turbo pressure, if I have good MAF and lower than usual boost pressure that means the air is metered and escapes between the turbo and intake. A leak and as this is already metered with the MAF the ECU gives fuel for that metered air, but the engine in reality does not get that air so we get rich mixture (black smoke).
Loving your bloopers. In case you're wondering. Is one of the highlights. The other highlight, is how we get there!
Another good video, but that cracked screen would be a fail here in the UK.
Hi, Dan. Nice to see you again, buddy. Great diagnosis…as usual! 👏👏👏
Thank you!!
Awesome video buddy. It’s great to see the particle counter used to diagnose the dpf system. Wish i had this in the past.
It's a real eye opener, it makes you "see" the great job the DPF is doing
in my country the technicians don't bother with diagnostics the reason they just fix the results and make money:( and if you find a mechanic like Dan you are lucky. thx for video
welcome back missed your great videos
Great to be back!
I like your test drive area. Very nice!
That's great you had that bulletin. It helped show the damaged hose. (Not Enough Air)
I started to think blocked air filter or air inlet, but without a Mass Airflow Sensor reading, it makes the diagnosis more difficult.
Great video! Hope the customer was happy. Also if this is a "pattern problem," I hope the OEM has an updated fix.
Thanks for watching!
