Sorry I realised after the video I was confusing Fahrenheit with Celcius temperature readings. Temperature sensor wasn't changed and the best news is the vehicle hasn't had a DPF error since.
Your thermo camera was in Celcius and the scan tool was in Fahrenheit. Still was reading higher than camera but not by as much. Also agree on those tuning boxes. Have seen them make black smoke on pre DPF vehicles. So DPF vehicles hide the smoke and block up.
Celsius and Fahrenheit gets me all the time. I need to Google what's higher Celsius and Fahrenheit each time ha ha. 100 Degree Celsius to Fahrenheit is 212 Fahrenheit. I need to find a way to remember off the top of my head without checking all the time. Any tips anybody ? They say... Double and add 30: To convert Celsius to Fahrenheit, double the Celsius temperature and add 30. For example, 30°C is roughly 90°F because (30 x 2) + 30 = 90°F.
LOVE your new tool! Great stuff BUT, never do a forced re-gen... my dopey son had his done and I was VERY upset! His Vivaros' DPF has now been damaged!
I'm goin mental here, I have one of these, I have a power problem, not that serious but annoys the crap out of me, I'd nearly drive from west of Ireland to you in the uk to solve it, your vids are excellent, serious mechanic💪
Sherlock Holmes hat again and well done. Big finger pointing at the after market mapping. I had one on my Disco 3 which worked well until it failed and caused no end of problems.... are they worth the small gain? I don't think so. Have a great one Jimmy.
Hi Jimmy, thanks for the great videos and advice. I do have a question. Have you ever damaged O2 and/or NOx sensors while doing those DPF cleanings? Or triggered some fault errors? Thanks in advance, and keep up with the excellent job. Best regards
we once got sent down a right rabbit hole by a mapped vw transporter t5. the injectors were sent off and tested because we though there was a fault with them, which there was. but at the test center, they all tested within spec, one was a little bit close to the edge of the parameters, but still should have been ok. because of the map and the extra rail pressure the van was running, this injector was actually no good and causing a drop in the rail pressure. total nightmare to sort out. owner didn't even tell us the van was mapped. spent ages on it and eventually it went to another garage who specialized in vw's and mapping them. he diagnosed faulty injector, which we had tested first! obviously the customer wasn't happy and we looked bad at the garage but if it hadn't been mapped the diesel injector tester place would have been right that the injector was within spec for normal rail pressures etc.
@ORileysAutos upstream temperature is usually EGT temperature not DPF temperature. is the sensor that you're showing the one at the exhaust manifold, or in-between the CAT and the DPF?
Good upload, these dpfs are nothing but trouble..i have a question for you. My c4 2014 1.6 hdi has a service light popped saying engine fault. When ive scanned it the difference in pressure on thr dpf on idle is 5 mg & 60 at revs. Bit the cinder level is 100% this has the eloys tank which is showing 795 ml. Any.pointers as to what I should be looking at. P1445 is the fault code addidtive exceeded or something like that.
Might be daft to say but that sensor is reading in Fahrenheit.. 300⁰F is about 150⁰C.. that's not much far from the camera reading. A d it measures exhaust gas passing inside and camera measures case temp. Don't know, what do you think?
Scaner showing 400 farengate witch is around 200 calcium. Termo camera reads 120 calcium of outside of DPF FILTER ( sensor is inside the dpf filter and reads 60-80 degrees of calcium more, withs is about right).
Merry xmas jimmy what happens to scan tools once the free lifetime updates come to an end can you still use them without updates. I was looking at the foxwell gt60 for my old mondeo and s60
Bluffs the reading to the ECU. A common one is to intercept the air intake temperature and to bluff the Ecu into thinking the engine is sucking in really ice cold air. The ECU will naturally add more fuel for the fake conditions. The issue with this is that DPF regens usually only trigger when certain engine parameters are met. Bluffing the temperature could have meant that it was always outside if these parameters and no regen is ever triggered... That twinned with extra soot from the fuel and 5 hundred forced regens from Halfrauds is a recipe for an unhealthy DPF
the tuning box is the problem. the only way they will work is if they are set up on a rolling road or road tuned. plug a play box as in just plug it in and it is done just don't work. seen many of these boxes causing the same problem once removed and new dpf all is good again on many i have removed these nissan and renault are the worst for it.
Hi Jimmy, I just saw on diagnostic tool that dpf sensor is reading in Fahrenheit, and your thermal camera in Celsius. Didn't get time to calculate but maybe sensor isn't problem? Good video as always
0:32 this is happening because you don't want to take thing apart and clean them manualy. You could take the diesel particle filter off and clean it with cellulosic thinner but.instead of that you're trying to sell a half fast technique where your tools are basically shootly up hasardly some aftermarket products in any holes you can and erasing faults.hoping that the probllem will not come back up. I don't get that oil dilution theorie.. how squirts of solvent in the exhaust pipe could ever go back in the crank case and do oil dilution..? The dpf is in the exhaust pipe. If cleaning liquid injected on the dpf that is in the exhaust pipe was ever able to go back the exhaust valve 🤨... and compression to the engine oil..? I don't get that oil dilution .. where is the oil.. you're not cleaning the EGR... you're cleaning the Diesel Particule Filter in the exhaust pipe right?
nissan mechanic here. the engine ecu alters the fuelling, EGR strategy + ignition timing during a regen, this contaminates the oil at a far higher rate than normal driving, it basically rips the oil apart at a molecular level, so the oil has to be changed after a forced regen [at about £300] we have navaras on our lease fleet that will do 9k between oil changes, we also have the bastard ones that only last 3k, these vehicles are supposed to last 2yrs between services, never ever happens... the dpf is 7 feet long and requires major stripdown to get it out, and typically the sensors strip out, so they cannot be satisfactorily cleaned out, and they are about £3k to renew compared to the old navaras, these french engined ones are dogshite, this is why nissan/mercedes/renault finished production in 2021... unfortunately they had a 5yr warranty, stroll on 2026...
Some diesels are injecting the extra diesel late into the cylinder and it washes past the rings into sump and contaminates the fuel...others are fuel in exhaust injection or fluid in exhaust injection.or fluid into tank injection..or a mixture of all of above ...so you can't knock someone's process if you don't know this... Don't shoot the messenger..
Some diesels are injecting extra fuel late into the cylinder to heat dpf ..this washes past the rings and causes the oil dilution,some are injecting the fuel at exhaust ,some are injecting fluid at exhaust some are injecting fluid at tank and some are a mixture of all of the above,so you need to know all that before you knock someone's process ,if your underneath a car looking at exhaust wondering how fuel contamination got back up exhaust downpipe into sump .you shouldn't be there.. Don't shoot the messenger

Well spotted !
Another sad story, due to aftermarket add-ons. Have a Great Christmas, Jimmy!

Retired mechanic 20+ yr ago i would never get back into this trade the hoops you guys have to jump through now' a real balls ache .......
Merry Christmas Jimmy. Thanks for sharing your wisdom with regard to these tricky faults which seem more and more frequent these days.
Same to you!
Tuning Boxes are nothing but trouble keep it stock they are bad enough when engineered by the Manufacturer !
There’s a world of difference between these stupid boxes & a proper remap.
A good remap shouldn’t make it smoke.
All the best Jimmy 👍
Half bet the turbine pressure sensor pipe is restricted on that 2.3dci as well.
Happy Christmas Jimmy!
Who takes a vehicle to Halfraud’s,
Merry Christmas Jimmy
Always a excellent presentation
Temp sensor is fine it was showing in Fahrenheit and you camera was in Celsius
merry Christmas great video and information always top man
Your videos are great, have helped me so much over the past year…. Keep up the great content!!
Thanks, will do!
Happy Christmas Jimmy. Thanks for all of your great and informative videos. All the best.
Same to you!
Merry Christmas to Jimmy and all viewers.
Merry Christmas and Happy New Year Jimmy 🌲🌲🌲
Same to you!

Happy Holidays

Doing what you do best merry Christmas jimmy 🎁🎄
Happy Christmas Jimmy, thank you for all the great videos this year, superb 👍👍👍
Thanks, you too!
Jimmy, you were comparing the temperature in Farenheit on the topdon with celcius on your tool 390f is 200C
Yeah sorry I didn't realise. My Launch is celcius so wasn't paying attention to the topdon
Happy Christmas 🎄🎁 Jimmy
Hi Jimmy, thanks for the great videos and advice. I do have a question. Have you ever damaged O2 and/or NOx sensors while doing those DPF cleanings? Or triggered some fault errors?

Tdi tuning box aka dpf blocker

Well explained Jimmy, makes a lot of sense. Wishing you and your family a merry christmas.
Scan tool was set to Fahrenheit easy mistake to make
Can't believe I didn't see that 😬😬 all was well after so no sensors needed. All working fine with no more DPF Faults
Do you ever use neat cleaner
What does the tuning box do? Seems unnecessary
Bluffs the reading to the ECU. A common one is to intercept the air intake temperature and to bluff the Ecu into thinking the engine is sucking in really ice cold air.

plug a play box as in just plug it in and it is done just don't work.
seen many of these boxes causing the same problem once removed and new dpf all is good again on many i have removed these nissan and renault are the worst for it.

Good video as always
Yeah can't believe I didn't realise that 😆😬 vehicle didn't get any faults return so no further work was needed and no more DPF fault
To convert C to F , first multiply x 1.8 then add 32 or F to C is take 32 then divide by 1.8 .
Just do force regeneration 😊😊😊
They should have stuck with the old Terrano lump- bulllitproof 🤡🌏
350 .F is 170 (ish ) C is that not ok.. stationary various revs..
( no argument here i feel i have education comming my way ) 🤞🤞🙏
If the tuning box is the cause ( hard to seek a different reason ) education is needed to consumers , if maps are needed to support
