ANY video is welcome - long or short - its ALL education to the problems on modern cars & how to fix them - We ALL appreciate the time & effort you put into making these for us - your a busy garage so see these faults regular - but for smaller operations - we only see these now & again - hence ANY KNOWLAGE is welcome THANK YOU PETER 👍👍👍
@@colinblythe3710 thank you so very much Colin, I have a lot of stuff going on lately so I’m slow on my reply recently but I’m just about at the end now. Thank goodness, but I really appreciate your nice comment 🙏🙏
Even getting a trade in on anything with the 2.2 skyactiv is really hard these days. Dealers don't want the hassle and the private market is flooded with them.
@@johnnyryan83 I’m finding that private owners are having more success in selling or trading the in once the new owner knows I’ve been working on it. Which is fantastic for me 😊 But yes, the best thing to do is to keep it once it’s repaired right, the savings come from not spending 20k on another car 🤔
@@raywalsh5822 gosh Ray, I wouldn’t say I’m any expert but hopefully seeing some of these issues and logging will help us all to find answers faster 🤞🤞
I will try your method tomorrow. I had exactly the same situation with a torn turbo valve flap, which I fixed. Then I was travelling at quite a high speed, the error ‘high particulate matter build up’ came up and errors p2458 and p2463 appeared and while I was trying to find a solution a third error p242f was added. This mazda really needs to be driven on the motorway as much as possible, that's my mistake, after fixing the turbo I drove mostly in the city and had a couple of incomplete regeneration and that's when I got first p2458 p2463 and then p242f. I'll report back with the result.
Nice Job again Pater with lots of useful infos! At the end of my wife's suzuki we had to change the DPF because from one day to another one it is totally blocked and zero exhaust went through on it: The DPF pressure sensor showed 600-900mbar pressure at idle and run out of measurement range 5V once the engine reved up. Exhaust exited through the pipe clamps instead:) I bought a new one from autodoc thanks to it it was only 133€ incl shipping and asked a local garage to replace it as I did not have tool to cut and drill it out in my parking lot.. Now everything works fine again and we passed the yearly inspection... long and painfully story with our beloved diesel suzuki, hopefully it will run long without any issues... if not I will take a big hammer and .....
@@TrailVapor I don’t really understand the question. But from 2012 or so on Mazda Skyactive engines have another egr control format on the exhaust camshaft design. This leaves the rockers underneath the larger lobe with no roller bearing (just hardened steel) This causes those 4 lobes and rockers to wear every 120 to 140,000kms
Mad world , how we have to pollute the environment to try and get pressures and emissions down 😂😂😂😂, as we know diesels produce shite , public only interesed in fuel consumption, top video Peter 👍👍
Hi Ken. My 2014 Mazda 6 dpf is regenerating every ~100km. mileage is 166k km. no fault code. What is the possible cause? DPF has reached end of life? I have done forced regeneration before once, it regened itself after 170km, then quickly fall back to every ~100km. Cheers
@@timbo19751975 ooohhh, I like your educated response 🙂🙂 Timbo is correct, check injector correction (it should be below 1 on all 4) And unfortunately the exhaust camshaft is most likely worn, once over 140,000kms 😔😔
car is currently doing 6.0-6.3L/100km despite regen happens every~100km. What i remember was the DPF regens approx every 240km and one day it suddenly dropped to 150km and now most commonly every 100-120km. Fuel consumption is ~5.0L /100km for motorway driving, i am thinking injectors are fine, the DPF could indeed got filled up with unburnable ash.
I have a 2016 Mazda 6 with 180k kms. I replaced the exhaust pressure sensor last year and there was a new turbo put in by Mazda 2 yrs ago, along with copper injector washers replaced. I get oil changed every 10k kms. I was going to post the same problem with the frequent regens, mine does it every 120kms. I had the car carbon cleaned last month - EGR, inlet manifold, intake ports etc done. Injector correction values all below 1. Car is going great, no warning lights, getting similar 5L/100kms fuel economy on motorway but a bit worried about all these regens. Would a worn camshaft cause this or is it more likely the ash buildup in dpf?
@@remotaurog I have seen all the same issues or items to fail on the all the way up to 2017 or early 2018. And the dealership doesn’t really want to know about it. But this isn’t uncommon for any warranty 🤷🏼♂️🤷🏼♂️
Mr. Kennedy I saw your video when you removed DPF from Mazda 6 - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lpJMFtD2dX0.html Could you please tell me, if I can remove DPF from Mazda CX-5 AWD, without removing sub frame, maybe even from top after removing wipers, wiper shield and metal cross brace. Thank you!
@@samostraser8924 the diesel particulate filter can be removed relatively easily from below without removing the subframe. But it will not go up the way. It is a bit tight but can be twisted out with some patience 😉🤞🤞
@@kennedysgarage3281 Hello, yes patience, I saw this when I was removing exhaust sensor pipe 😁. Almost no place for removing bolts 🥴, you have magic hands and good tools. Did you removed DPF from AWD Model of Mazda also, without removing sub frame, because there is little less space. What do you think about cleaning DPF on the car? Do you have any experiance with helicoil or time-set, better not ask me, where I must have repairing thread 🤓
@@samostraser8924 generally if the Dpf is blocked something has caused it to happen in the first place. And it is generally an exhaust camshaft or turbocharger or similar, so very often I will have the engine removed if taking of the Dpf. But it can be removed from the all wheel drive CX5. I find removing the subframe retaining bolts and allowing the subframe to drop down 4 or 5 inches works best for me 🤔
@@kennedysgarage3281 Thank you Mr. Kennedy, yes I know something caused DPF blocked, mybe just too many km ;), over 260.000km So after I replacing exhaust sensor metal pipe, regeneration started at around 200km (I know its not good its not bad). Some values before and after regeneration at idle: Before: PM_ACC and PM_ACC_DSD are 5,49g/l (REG started at around 6), DP_DPF pressure around 1,5kPa, PM_GEN 4,14g/l (this value is not as good as before, when the car was little younger :p). Before PM_GEN was always more than PM_ACC and PM_ACC_DSD, and REG started when PM_GEN was about 6. If I drive slow, PM_ACC and PM_ACC_DSD stay bellow PM_GEN, otherwise raised above PM_GEN and this trigger REG faster. After: PM_ACC and PM_ACC_DSD are around 0,15-0,20g/l, PM_GEN 0,03g/l, DP_DPF pressure 0,0-0,3kPa When acceleration DP_DPF pressure raised (I am not sure how many) 10kPa and more I think, mybe this mean that DPF is little full. Camshaft and turbo, better stay healthy, car runs too good :p, just DPF reg need some doctor :p. I have plan to put some LM cleaner and rinsing fluid into DPF and check, I think this cannot make things worse. I have also plan, to replace injector washers again (after 60kkm). And if was not better, I must carefully look under valve cover (I am scared ;( ). Any comment about upper values from Mazda Doctor will be gladly welcome. Thank you, have a nice day and I hope, you will teach us about repairing even further on your videos 👍
@@samostraser8924 the regeneration did help. It isn’t unusual to see 10kpa exhaust pressure under acceleration. But a good chemical clean would most likely help to extend the life of the Dpf and the distance between regenerations 🤞🤞
