fault codes in ecu.. P2463 Particle Filter P24A4 Particle Filter where nobody checked was the BCM.. B1029 exterior temperature sensor fault that is located within the wing mirror.
Nice one Jimmy 👏👏 If it wasn’t so tragic that this chap had spent so much money to rectify the problem this would be laughable, it seems to me that most garages just throw parts at them at the expense of the owner and need to be held accountable if they can’t find the issue, let’s face it the answers are out on the Tinternet Web Thingy with a little bit of searching, I know these modern vehicles are a minefield of electronic wizardry that even the main dealers seem to struggle with, though they should have the training and specialists equipment for their own brand it seems to make no difference to the problem solving, I’ve heard so many similar stories to this one especially with reference to the Transit customs. Keep the content coming Jimmy 👍
@@curtisducati same as that mate I had two Smiles and 3 mk6’s & all done close or just over the 300k mark the last mk6 had done 100 miles under the 350k so you just beat me 👍 the engine was still going strong but got to the stage when I was fed up of laying on my back welding the thing up for each MOT. Was in Shopfitting for 35yrs so they were all motorway milages & thrashed every day.
Next doors Vaxhall van hits 400 miles and a fault shows up. The things been back to the dealer more than on the road. Did it from new ,its on a 23 plate, it's the same as this one only badged as Vaxhall.
Amazing to see that not one of the previous garages googled "external temperature sensor" just goes to show we don't have any mechanical brains anymore, just part fitters.
Unfortunately modern cars and trucks only work because of dozens of closed loop circuits which require some reverse and logical thinking to fix. The primary qualification for fixing vehicles is electronics and industrial computing. Secondary to that is being a mechanic. The 2 are not really compatible. A mechanic may work through a check list to clear run of the mill faults but without detailed understanding of how the system works as a whole complex and unusual faults will never reveal themselves.
Some were at least going back a few years. My father was an outstanding mechanic but left the trade when the garages went over to replacing whole units instead of repairing the old ones. I worked with him on his private customer's vehicles from when I was 9 or 10 until he'd had enough in his 60's and we did everything from servicing to engine overhauls. I serviced and maintained my vans when I had a same day courier service and I still maintain my motorhome and everyday vehicle now. Dad is gone now but he taught me well. Either you're too young to remember when real mechanics existed or you should take your dog mess covered glasses off.
Another great video, I work on commercial vehicles and see this problem all the time, a lot of sensors are in the mirror housing and there always getting hit, keep up the good work, as always great to watch and very informative.
I'm replacing my old 2002 van and while at a used van outlet yesterday I looked at a dozen or more vans from 2013 - 2018 ..I noticed they all had a certain strange industrial (unpleasant) smell, do you know what could be causing that smell that they all had in common? If they all smell like that I'll keep my old van.
I'm sure I've come across topics covering adding temperature sensors to the older boxer that didn't have that function activated. I think you can just buy an appropriate thermistor and use that. you'd just have to get hold of a sensor used in a factory mirror and measure the resistance readings in 2-3 temperature point and then put the reading in an online calculator which will tell you what thermistor code number you need 👍
NTCs come in standard values, measured at 25°C, the temp coefficient as you said can be calculated from different readings (easy to get accurate 0°C with ice in water, then ambient temp with a thermometer). When you have the right thermistor, solder wires to it and pot it in silicone or epoxy (for weatherproofing). The thermistor itself costs less than 1 euro at Farnell, TME or any large electronics parts distributor
@@brainndamage I use a decade box connected in the circuit and as you adjust the resistance you can watch the temp reading changeing. good simple diagnostic tool
just fitted the temp sensor I bought from eBay which cost £10. I hope now that I have a temperature displayed in the van it will run as it should. Excellent work! Many thanks for the video!
Brilliant video! I use a Citroen Relay for work and my driver's wing mirror has cracked around the plastic indicator. Was considering purchasing a replacement off ebay, will definitely not be doing that now 👍👍👍
I'm sure I just saved you months of headache. I've seen this story a dozen times now. Just the ones that came to me so God knows how many people are suffering with this issue
I had a 2016 Boxer van with 40,000 and the engine blew up (thankfully fixed by our dealer) but it had dpf faults nearly every week of the year we had it. I wish I had seen this video back then. I was glad to get rid of it.
This is why people need training to fully understand how these DPF systems work. I hate them I think they’re shite, I’d love to do an emissions analysis on what’s coming out when a regen is performed. But there’s no going back in emissions laws now so people need to get trained better! Top job mate you really showed how diagnostics should be performed
Hello from a Pensacola Florida! I myself was a dealership technician before I got out of the trade. It seems like good diagnostic technicians are a problem world wide. A very basic inspection would have told anyone with a brain what the problem was. Unbelievable.
Back in 1988 I had to call out the AA to my broken down MG Montego. The chap said "these modern cars are a nightmare so we have to look for things that appear to be out of place". He quickly found a broken wire in a plug wrapped with blue insulation tape. Problem sorted. My 2007 Sprinter has given me plenty of headaches which I have successfully resolved, thanks to my dealings with the chap from the AA all those years ago.
7:42 wow this was insightful Jimmy.. You are nothing les than a Legend.. Wish you were closer to me I'd be straight to you for sure. . Not meaning to sound daft but I take it this is generic issue across the board ? Makes sense it meeds to read the surrounding air temp... I have a 2ltr insignia ecoflex... Lets just say its getting on my last nerve... Too many sensors.. Great videos I enjoy seeing your honesty..🫡👏👍
Very interesting video. I'm glad that my old Peugeot diesel car doesn't have a crappy DPF filter on it. I've kept my car for almost 10 years and self taught myself all about mechanics. My car is almost 20 years old and I wouldn't want to change it for a more modern car otherwise I'd have to invest in £6000 for a scanner like you have in this video. And that's not going to happen 😂
This is a great video, and you are a great bloke. Very interesting. You have a mischievous streak in you though, you were really teasing that poor customer at first, knowing full well he would think it absurd that a mechanical engine fault would be fixed by getting a new wing mirror! Was funny though. Best wishes from England.
(can't believe they didn't see that error on the scanner) On My car external temperature sensor was for some reason mostly wrapped around the radiator hose witch caused mainly issues with climate control system, so it was reporting high 60c outside so the 26c setting on the thermostat control did basically nothing (unless set to max witch just sets the flap to 100% open regardless of outside temp) once the radiator pipe got hot even thought it was like 10c outside also caused running issues of the engine when it was -5c or lower outside as sensor would start reporting 20c outside temp at engine start (guess it was slightly damaged) , once it was reporting 50-60c caused engine power issues (guess because outside temp was reporting incorrectly high it was trying to not overheat the engine or was messing with air intake/fuel mix calculations)
You can replace the outside temperature sensor. The sensor and associated wiring and plug will cost around £50 from an authorised dealer. The wing mirror has to be removed along with wiring ( the two plugs shown in the video). Then the two mirrors with have to be unclipped being careful not to break them. The new sensor can now be installed. Replace mirrors and reattach door mirror to vehicle. Do not buy new sensors from non PSA sellers. I did that and the temperature read out was 40 degrees C +. However it does not seem to affect the DPF. If you do break the mirrors ( I did ) you can buy new ones on line for about £16. All much cheaper than £200+ - £700 for a new mirror.
Curious to know if it regens on its own now, I have similar troubles. 10k thermistor from RS is a good replacement for the often missing temp sensor, the eBay Chinese sensors are a waste of money and don't work.
Sure others have said by now fuel level code is set when low fuel light is on and will stop regen when driving it will self reset when the tank next sees more the quarter full tank
Seems to me there’s too many electronics on modern cars and can’t be easy to find the real fault. I’ve got a 2016 Renault Espace, this model isn’t available in the U.K. I love the car but a have a reoccurring fault that shows up every year In August, I get the STOP warning come on and a message saying Braking System Fault. Renault mechanic plugs in his computer and there’s nothing, he says it’s a bug, he deletes the error and I’m good to go for a yr. I’ve looked up this fault online an it could be many things causing it, even down to the battery. The only thing I don’t like about the car is there’s never a light showing when it’s doing a regen of DPF and as I do mostly short journeys often I stop the car mid regen.
Do you know if it would cause problems with the cooling system on the relays , thinking of cooling fan and thermostat control ? i have one on which almost every component in the cooling system has failed, leaking water pump, oil cooler mixing oil and water , EGR cooler , leaking thermostat, and leaking radiator. all the componets have been replaced at some point in the last year, it goes away runs great for a while until the next item fails. looking at fan and thermostat actuation today it seemed erratic and i also noticed it had no dash temp display after watching this i`m wondering if there is a connection, thanks
More and more these days,most garages seem incapable of fixing problems,because their so called 'technicians' don't have even the basic idea of how to go about organised basic diagnostics. They look at an electronic screen,jump to conclusions and then throw parts at the problem hoping it will magically go away,all the while charging customers handsomely for their ineptitude. I am in my seventies,do all my own vehicle maintenance and have been doing so since a teenager. I have no intention of placing my vehicle in the hands of someone I wouldn't trust to service a wheelbarrow.
I would be interested if replacing the outside temperature sensor had an effect on the fuel low fault. Cold day means lower air pressure which in turn could effect pressure inside fuel tank, bit of a stretch but you never know.
@@rupertgethin-u5p warm day fuel vapour will expand causing an increase in pressure. Cold day creates lower pressure. Commonplace known as oil canning.
That's unreal the amount of money people are loosing trying to track faults down due to these stupid dpfs and to top it off a wing mirror sensor sorts it
Modern day vehicles with all that electronic crap in them that goes wrong. Thankfully i hate modern day vehicles and thats why i love my iveco daily mk3.
Car manufaccturers: Let's make computerized systems for the cars that can detect everything on a car and stop random things working without actually telling anyone what the problem is directly. My next car will be from the 80's.
You don't know what the problem is if you're, let's say, less inclined to have a great number of neurons. Diagnosing a car has never been easier. That is, unless you're a boomer that looks at computer as if they've got seven heads.
@@tobiascat6173 You need to improve you comprehension skills. Both for reading and understanding comments and then, to properly read manufacturer walkthroughs. And as if that isn't enough, your need to add a "fact" to the end of your sentences, trying to convey some more importance to the word salad you just wrote, tells us everything we need. Your knowledge about these subject is at best limited. That is indeed a fact. Incompetence, sadly is everywhere and dealerships are no exception. If anything, they seem to concentrate inept people. Run the rings you want grandpa. Couldn't care less. You just confirmed every single stereotype there is about your kind. Next time try reading about how the fault systems work and how they are standardized. Might save you from looking like a fool in the future.
Well he did go to Halfords and kwiikfit, what did he think would happen? That's like going to a pool party at Michael Barrymore's house and expecting good things to happen.
I have found that ambient air temp sensor is a critical sensor for a many components in a modem day vehicles (especially diesels). The two one's I have come across was the first one I had, the parking sensors where not working (parking sensors need this temp sensor reading in case snow or ice may be present on the sensors which may cause unnecessary sensor activation). The second one was for a AdBlue concern. (as you may know, the AdBlue system needs to know the ambient temp in case of AdBlue freezing for heater regulation). Good video and excellent information, subscribed.
You're right, I had my entire AC system in my Astra stop working after hitting a bird at high speed. The bird took the wires off the temp sensor behind the grille, and luckily as it was a hot day I noticed the AC stopped blowing cold immediately. I thought it had punctured the condenser and dumped the gas but was surprised it was still holding pressure. Only after replacing the exterior temp sensor did the AC start cooling again. That car is not new and surprised me that there was a connection in the vehicle software.
Wow! Don’t get me wrong, I’m not even a van owner But have thoroughly enjoyed watching your videos and your diagnosis process and was an eye opener to see a wing mirror can affect the dpfs operation! If only this chap went to someone like you first! & why I only trust a few diff ppl to diagnose any issues on my car that I cannot! Well done Sir! Keep up the good work 😎🙏🏻
I'm totally team O rileys! Had this on a 2.2 transit with a broken wire to ambient temp sensor. Caused all kinds of problem. Can't believe mechanics don't think that sensors irrelevant. Another nice diag. See you tomorrow in the next one! 😉
I think telling someone it is the wing mirror is confusing because it isn't the wing mirror it's self but the temperature sensor inside/attached to it. New vehicles are so complex with all the sensors. Good job Jimmy, I bet he very happy with you when it was sorted. If I ever had a DPF issue I'm pretty sure I'd come to you to sort it. 😄
I agree with you, too many sensors!!! I preferred a dumb diesel, that starts, runs and stops when I tell it to!!! Had a VW that ran for 260,000 miles, no probs, then a mechanic reckoned I had a diesel flow issue and fiddled something to make the fault go away. Then, after turning off the key and removing it, the engine continued to run!!!!! Outstanding fuck up!!!
Instead of changing a complete mirror you can dismantle mirror and replace temperature sensor with a generic citreon one of ebay for £9.99 just cut ends of the plug and wire 2 ends on to them. Doesn't matter which one is which. Worked for me!
The actual sensor component is probably available for pennies or little more from an electronic component supplier. It would be informative to investigate the actual resistance at various temperatures and check out what's available.
I was involved in the external temperature sensor at a vehicle manufacturer so I'm not even mildly surprised that it caused this error, but it's annoying that they couldn't figure it out.
Good job, I’d no idea the external air temp was used by so many systems in a modern car! To get a true reading it’s got to be external to the vehicle though which immediately makes it vulnerable to damage wherever you put it, putting it in the engine bay would make no sense. Ironic it’s in the mirror though, perhaps the customer should take the old one to the previous garages so they could take a long look at themselves for not sorting the issue themselves!
Wow this is eye opening I’ve watching your channel for awhile now and love the information you give I have a 2006 2.5 Vw crafter and it’s a minefield trying to work out what is going on with them Keep up the great work
Yes VW are an expensive PITA to fix. I gave up on them and brought a new MAXUS Deliver 9 and its been easy to work on with the rear wheel drive. 80.000 KM and goes awesome. I do change oil every 10.000 km NOT the 30.000 km dealer bullshit still with the high spec oil.
The reason why you have the back and forth is you didn’t explain the problem to the customer like you did to us. You just said “you need to replace the wing” mirror. Of course he was baffled! 😂
Seriously, who the hell goes to Halfords for that sort of repair??? I had a pre adblu and changed the mirror and it had exterior sensor but never affected it. Still going 298000 miles no problem
I've had a 2014 2.2 Boxer for almost a year now. The outside temp sensor is like the one in your video, clearly its broken but I've had no DPF issues. Is it maybe down to the older not needing it as much as this newer one?
Garages are there to make money With or without even fixing the problems They change this sensor and that bolt and what ever else clear the codes and your on your way not knowing they have had your pants down Well done Jimmy 👍 Keep em coming
I ran my boxer for a year with a faulty external temp sensor with no dpf faults,eventually replaced a few months back with one of ebay for around £10 and it works fine.
Well done shows that some dealerships don’t know what they are doing change this change that and they still don’t know my comment is electronics in any vehicles pain in the backside
My 2015 Ducato doesn't have a sensor fitted from factory as I've activated it in multiecuscan and it's blank. Maybe it's different on those than the boxer? Mine is gutted and mapped out so will never block 😂
There are so few mechanics around these days - all main dealers just employ 'parts fitters' now it seems. Fire the parts-cannon at a problem, charge the customer, and hope it goes away. Odd that they never refund when it turns out the parts weren't needed. It's the same in the bike world too unfortunately - they won't do diagnostics, they just change (expensive) parts & hope for the best.
Hello. I have a 2014 Citroen Relay X290. I’m having DPF issues and my temperature reading is also blank on the dash. Could this be my issue too, or does this only affect the Boxer? Thank you!
Must have been some find the first time you did it! Modern cars are complicated and many systems depend on each other.. Thankfully there are some of us who are interested and willing to scratch our heads a lot :D
This is a big problem with modern vehicles, basic workhorses are far too technical, electronic, and full of gadgets, I believe to keep people away from DIY and what we used to call "under the arches" mechanics, and force owners to literally waste fortunes with dealers, It's a sad state , I know my way round engines, but all the modern computerised techy stuff I just don't know about, and that is why I would never actually buy a new vehicle, I just lease hire. Well done Jimmy for being a decent honest guy, with a good knowledge. In my experience of modern garages and dealership garages there may be one guy who can actually read who is the "foreman" and a few under experienced grease monkeys who just do as they are told, and their hourly rates are eye watering, simply another case of ripping off the motoring public.
I remember this issue you found on my van,, which was stuttering in the morning when cold,,, I actually bought the sensor, separately amazon, perfect, no stuttering in the morning
We come across alot of dfp problems where garages just replace sensors and installing new dfp filters. Some even replace turbos and injectors to try to solve this. They never look at what the conditions have to be to get a filter to regenerate. We do alot of BMW and most of the times it is the thermostat that is stuck open, So the engine will not get hot enough to regenerate. Also the fuel level has to be high enough to activate DPF regeneration.
these days that makes perfect sense i used to joke that i could,nt start the engine cuz the ashtray was full that was back in the 80s who would have known it really can get that stupid for real well done dude for finding that fault seems like you knew already good job
£700 for a mirror. It’s a good it does not stick out the vehicle and easily smashed off. It’s also a good job it would not affect engine running. What a rip off. Nice diagnostics! Use of brain power instead of repairing the results fixing the problem. The sensors are all part of a maths problem to work out regen and other associated problems. In a cold climate it might have to run longer in a warm climate shorter. Take one of the required numbers away from a calculation it cannot be done so it does not. You get a power reduction eventually with blocked filter and a fault code what more to do than fix the sensor the causal part and then do regen.
He should claim his money back from these so called "professional garages" All he has to do is show them this video. If it took a guy in a van 2 mins to sus the fault and they have massive auto centers with tons of equipment then they should be ashamed of themselves . Why are they not using these diagnosic tools??? Main point though is that there is far too much shite on vehicles these days and the smallest thing can throw the whole system out of whack.
