Great video Bro👍 Honestly you're a Pro😉, plz make another video on a similar case study showing how to step by step diagnose this type of fault & which PID's to keep an eye on🕵️♂️ Thanks for sharing Bro, Stay Safe👍
@@romanosautomotive yeah, use silicone hoses instead. This engine gets so hot when stationary that on a hot day, the AC can't cope and it'll blow warm air.
Ok, loved the video, but I’ve got a question in my mind about how the boost leak causes a clogged dpf. It’s been my assumption on a turbo diesel that the ecm will only fuel based on the current intake pressure. If there is boost you get fuel and less/no boost you get less fuel. Apparently that’s not the case if it will overfuel with a boost leak and clog the DPS with soot. There’s obviously something I’m not understanding correctly. Glad the regen did the trick, but I was hoping to see the device you had mentioned come to save the day.
Hey Kevin, the ECM is basing fuel delivery on air flow measured. Boost creates more suction through the air flow meter so the ECM delivers fuel for the amount of air measured. But the calculated air doesn't make it into the engine because it's leaking at that main boost hose. So just constantly overfuels. Does that make sense?
@@romanosautomotive oh yes that most certainly makes sense. I had overlooked the possibility of there being a MAF reading. I work on a few medium duty diesels in school buses. They don’t have a MAF reading only boost reference, intake air temp and maybe an atmospheric sensor. Different ecm strategies. Probably more like a speed density system. Thanks for taking a minute to explain!
DPF systems on North American pickup trucks are a nightmare. Had a friends quit the trade partly over this. Warranty work paid for too little time to do all dig and fix. Always a squabble between shop owner and manufacturer. He's now a fireman. Will also get a better pension at the end of it...
Nice Rob. Dpf and ad blue just love them. Nice use of the scann tool. I usually look at the dpf sensor koeo 0v with scanner and then with engine running. Then verify with manual gauge. I have been told once you have an engine light on they won't regen themselves. What do you think.
@@romanosautomotive key on engine off 0 bar, engine at idle less than .010mbar and at 2500rpm less than .050 mbar for a good dpf anything above this I find to be an issue.
I am not really fan of doing DPF regeneration through the scan tool at the workshop. I prefer doing it manually, on the freeway (or payway😂 ). With the scan tool, I think, you stress a lot the engine.
It's great Adam and super fast. If you know Gscan, this is a walk in the park to use then as it is basically the same software. I don't think it's replacing it, just an alternative tool while the Gscan3 is off the table due to hardware supplies being low.
Mate I had exactly leaks on the same areas of both hoses. Seems like a deliberate weak spot built by Mitsubishi to make extra profit for charging 1000 AUD for the 2 hoses. I hate Von Bibra.
Long waited DpF video..keep it coming..!
Appreciate it Prashan!
That was the best instructive video that I have watched. Keep adding to it. ⭐⭐⭐⭐⭐
Thank you Ralph!
Perfect same split and problem on a MY2022, thanks man!!
Good diagnosis and repair Rob.......You are loving that new scan tool! 😉😉
Haha thanks Max but not for much longer. It's going to my tech in the mobile van 🙃
@@romanosautomotiveBuy one more, for the shop 😂😂😂
@@romanosautomotive Oh NO! I get it now......it's just an excuse to buy another new tool for the workshop! 😁😉
Nice one Rob. Good to see some DPF stuff. Just had a VW Polo in the other day with DPF fault. Oh what fun lol
Cheers Kirk, did you solve it?
@@romanosautomotive yeah mate. Good as gold now
Great diag and repair. Thank you for sharing.
Thank you Ravindra!!
Great work as always. 👍👍

Thanks Salman, I will do on the next one for sure
Great video..
Another problem fix
Thank you awudu!
Nice one mate! I've had this exact fault before - both hoses.
Must be somewhat common
Cheap material maybe?
@@romanosautomotive yeah, use silicone hoses instead.
This engine gets so hot when stationary that on a hot day, the AC can't cope and it'll blow warm air.
Nice one Rob.
Thanks Jeremy 💪
Awesome job 👍
Thank you Shaun!
This was so helpful… how much should a repair like this set me back? Same issue in my car and don’t want to be ripped off.
Are you in Perth WA? If so, we are too so google us and give us a call and we can look after you.

it makes the engine create more soot due to a rich mixture.

Thanks Denis. I think the DPF nightmares are all over the world 🤣
always interesting!
Thanks Johann!
This is incredibly helpful as I also have this exact issue!! Any idea what the part number is for the first tube? I'm having trouble finding it.
Direct from Mitsubishi Cassie. Give them a call with your vin number and they'll get you the right one.

Thanks D.D and not necessarily. Usually I find it may or may not regen depending on how overfull the DPF is. What do you usually see?

You'll cook the DPF usually. They can't handle many stationary regens, so you are correct good sir.
Hows the zenith Rob ? Do you know if its replacing the gscan brand?
