@@dans_Learning_Curve small insulation thickness, which dries with time and cracks, all pvc wiring does. Second, expose to moisture, freeze and road salt, remeber this is under the window wipers.
In my youth I had about a dozen water cooled vw’s , any with an mfa would become a problem. A wire or a bulb problem with the mfa and you’re walking home. Nice to see it’s still a problem. 😀
It becomes really interesting when the wire connector is intermittent and the act of of inserting a back-probe makes it a "good" connection! The back-probe takes out the slack between the pin and the cavity (female).
I feel like a failure sometimes when I constantly have problems with my 22 year old car and it's reoccurring ignition issues. I'm reasonably competent at fixing cars, as I've been doing it for friends and family since my mid teens. There's nothing like the kick in the jewls of spending an hour or more diagnosing an issue, only to find that it's a bad spark lead ONCE AGAIN. It's videos like this, where a serious seeming problem is traced back to a simple broken wire, that reminds me even the best out there still need to call for help sometimes.
Dan, I don't know how you can accept a vehicle that has been taken apart and messed -up and then you do the repair. I'm trying to learn some diagnosis myself. Thank you so much. Do you put the vehicle back together or return it as it came into the studio?
Another good one, Dan. But I'm still confused as to what caused the wire to break? I know you mentioned green crusties, but how did they get in there? Is this another example of the failure of the Euro obsession with "biodegradeable" insulation? I've worked on cars with 60 year-old insulation and the wiring is still solid (except at the ends, of course). On my 15 yo BMW the insulation has litterally fallen off of some wiring.

@@Diagnosedan "Easitronic= oxymoron". Car manufacturers are becoming absurd with thier infatuation with electronics. Its no wonder theres a car shortage. No one can fix these dammed complex things anymore, and dont really want to. Imagine all the cars getting into accidents where the hidden wiring gets trapped, cut, mutilated etc during the collision event. Just an unending nightmare for everyone involved A car with only 70000 km should not have these kinds of problems.
@@BertGraef I hate modern cars! This is what an electrical system of a car should look like! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FcGy17xPB3g.html
ICT sector calling: None of the equipment he uses (with the exception of a multimeter) is used in the industry I work in but the structured approach and common sense he uses to tackle these issues is something that should be taught in any industry/technology that uses troubleshooting processes. EDIT: This is what keeps me interested as a non-mechanic/electrical engineer ;)
Hi I’m in Canada 🇨🇦 and that green corrosion inside wires is very common on all VW/Audi cars and heard domestics have same concern. But Dan’s diagnosis can be applied to any car.
@@beluxauto5968 nthn in the video or the diagram suggest that fuse 14 & 21 are fed by the same source, beside he is saying “testing fuse 14, but he touches fuse 21 instead”.. im not picking up on the mistake, as the outcome was luckily good.
It's very refreshing to see Dan being fair and mentioning the two repairs are independent form each other and pure coincidence and bad luck. Usually you get the old :"they must have done something" etc. Props to you Dan, not just for being a great mechanic and diagnostician but also a great human being.
Well done Dan. I allways enjoy watching your fixes, but how would you have ever been able to track this without Autodata or OEM wiring diagrams? i used to enjoy tracking wiring / electrical faults but had to eventuly quit the industry, as the horrible costs of Autodata & OEM data made it all most impossible to make this viaable to me. I am just pleased to see someone like you suceed against these. Really good job. Keep up the good work Dan
Whatever car you are working on you can get a 1 month access to Alldata-diy, or 1 day access to OEM wiring diagrams for a few dollars. It really pays to use those resources.
@@mrfrenzy. can you please send me a link for this. I actually needed a wiring diagram for my personal car the other day to trouble shoot a intermittent shutdown. Eventually I found the problem by accident as there were a broken wire that made contact, but sometimes would loose that.
@@Bosbulls well it depends what country you're in and what brand car you have, if you have a car that exists on the American market just search for "alldata-diy". If you have a small European car you need to find the manufacturers website where they sell diagnostic info (which they are required to both by EU and USA laws). Some brands require that you have a company to get access but the price is usually reasonable.
I love how Dan has everything flowing logically. I have several electrical problems in my 2006 Golf V, and instead of logically flowing through troubleshoot, I get stumped at "Wait, what does this wire do again and why did I even follow it?" Your videos inspire me to try again!
Love your work Dan. I hope you are as busy as you want to be and that you are getting rewarded well for it. As usual, well presented, clear, concise, linear, and well communicated. Really enjoyed this and watching you work the process.
@@Diagnosedan You're more than welcome!!!! (het beste wat autominnend Nederland is overkomen de laatste jaren, ja ik ben een fan, geen monteur maar een ex beroepschauffeur nat en int. nu een pensionado zonder al teveel kilometers, ha ha ha)
Thank you Danny. As always, it's a great pleasure experiencing your thought process as you take us along on the diagnosis and repair of a vehicle. Your efforts in producing these videos are greatly appreciated, thank you sir.
This is my first time watching your videos and I must say that I am impressed with your diagnostic reasoning to isolate and resolve the issue. Common sense, when used properly works wonders, as you have demonstrated.
great video. major respect for your skills and ability to explain it to others. also SO glad you showed your wire fix using solder and shrink tube! NO CRIMP SPLICES! You provided an example of the correct professional permanent repair. great job
Nice job!! In some cases, a broken wire can be very hard to find, especially when the wire in question looks okay, when it is not, because not all wire breaks result in the wire breaking completely. These cases are when the wire breaks without breaking the insulation.
In those cases, I just tend to replace the entire wire as best I can. Normally most wires can be fed through existing grommets etc. Yes it is a bit of a bodge but use high quality wiring, route it in a way that a mechanic taking apart something else won't break it and it'll last the life of a car. It's usually not economically viable to remove the entire loom to check!
I had exactly that on a ground wire on my outboard motor's Power Pack.....all the grounds LOOKED great, until I wiggled the wire at the terminal. Marine environment is rough. This car though...I would NOT have thought the wire would be broken there.
Geh, I had a similar no start problem on a Meriva with the same gearbox, due to the wire that controls the fuel pump being broken inside the ECM and *sometimes* not starting.
12:29 - how can u give ground to a power wire or what does that probe thing even do to the relay then? it might also be highly unlikely that the wire broke in just 1 day, so the old module might alos be ok, it just didnt function properly with half of the amperage or smth?
Well done on an other great repair. Exactly, using common sense and the wiring diagram you were able to find the fault. I have often used this exact method, start at one end of the circuit, normally the easiest to access part first and work your way along. This has served me well countless times. One thing I would like to point out is, that corrosion in the wire has been there for a while. There is a possibility that it was the cause of the original fault, or if the control module was faulty it may have been the cause. There would have been high resistance in that power feed to the module, and with the fact it completely failed the next day after getting a new TCM, I would bet it was more then likely the cause of the transmission shift problems. I would bet the circuit was having intermittent opens as the wires were only just making contact. It definitely looks like the previous person who tried to diagnose that lost their head!😄 stuff pulled out and disassembled that did not need to be. It is amazing how so many people on this industry can not diagnose electrical, I mean a broken wire is pritty simple. It is sad that the guys like me who are good at this don't get appreciated for that fact we can do what many in this industry cannot. Keep up the great videos Dan, I always enjoy following along and trying to think of the next step before to show it in the video.
@@Diagnosedan then I still think that wire may have contributed to the module failing. Either it was broken and touching slightly on and off causing voltage spikes. Or the excessive resistance and low voltage caused the TCM to fail.
This makes sense. I do not believe in coincidence when work was done shortly before. I am a software engineer and sometimes after a software update some other problem arrises. More than often the other problem has some (unexpected) relation with the work done before. I like this channel and always wondered why a garage cannot do proper diagnosis. Without analytical thinking and diagnosing I cannot do my work.
@@pcdispatch Has to do with a lot of things. Maybe they can but it takes a lot of time and a lot of equipment. And who's gonna pay for that? Most customers don't understand what it takes to find a problem.
Great repair! but I must ask where are you getting all these Euro cars? Also what insane engineer decided that the wiring must share space with the water drain?
Was het niet eerst een intermitterende storing Door dat draadje naar pin 1 nog niet helemaal Door was.en was er dan werkelijk iets mis met brein van bak
I'm not a car guy so I'm not sure why YT's algorithm suggested this video. LOL But I'm glad it did. I'm an Electronics guy and of course, following along with the logic flow was great. So well done. This video, as well as the one pinned, shows that this model of car has factory issues in that area. I'd bet that there's too much tension on the wiring harness that causes the wires to break over time. I mean, in both cases, the wires that broke were a clean break. Almost like they were cut. This is good to know and just might assist when troubleshooting any other vehicles. Job well done!
So you get charged for work carried out without the problem being fixed and what about your inconvenience. Somethings don't change and the customer is the loser. So the workshop could have replaced 99% of the car without success and billed you for their incompetence.
Dan your great!!!! I want to ask you about the oscilloscope. You was using a tiepie oscilloscope…… why now you use picoscope ? And thnx a lot for the great videos
Thank you very much colleague, I plan to buy a subscription for you TSB soon, I really appreciate you helping us first of all thank you again. Few people like you have lived.
You know if you weren't called Diagnose Dan, I would still be calling you Diagnose Dan! Great explanation and find as always Dan. You never fail to impress me in your videos!
I remember when my mon used to take the car to a different mech for electrical issues. now I see why it would be... not everyone can ready electric diagrams and go do such deep dives. This guy is the total mech package!
Great video again Dan. You always make it look so simple. Then again, with logic and common sense it is simple, but you just need to know where to start and good diagrams and stuff... Great fix! How long did this take you? About 2 hours with filming?
Filming actually takes alot of time. Its hard to get good pictures of what i'm doing and under the bonnet and insider the car the light isnt always great so i'm always trying to make sure you guys get to see as much as possible. This can make the job take three times longer than it normally would
Information is a key to diagnosing most faults. IE good wiring Charts and knowing how to read them. You made it look so easy Dan. Thank you for showing your technics
@@Diagnosedan true, I found one just 2km away. Even better he loves it if customers like to fix their own car in his shop. Will give you pointers, help and mostly doesn't charge anything for using his shop either. So as apriciation I will buy the parts and or oil from him. So both of us are happy.
Great video Dan! I used to own a MK3 Clio which had nearly identical problems in that area. Due to poor design the scuttle drains would frequently block with debris, leading to standing water and eventually it would make its way into the cabin and cause all sorts of electrical issues. Ended up needing an entire fuse board replacing due to corrosion.
We see plenty of these Corsa D 1.3 diesels with drowned ECU's. They sit on the 4 studs next to where your wiring fault was. When re-fitting, we remove the drain grommets and raise the ECU and wiring loom up on some M6 nuts. Its almost like they were designed to fail 🙄 At least you didn't have to deal with rodent droppings!
On some of the Opels they had the brilliant idea to move the ECU in front of the left wheel, guess what happens when it gets sprayed with mud and salt water for a few years :)
@@mrfrenzy. same story with a lot of fords. The ECUs are protected in a nice little box behind the arch liner, but the loom is just left to sit at the lowest possible point and soak up all that lovely road water
I appreciate how you go into so much detail and explain the thought process behind the diagnostic. People think our job is so simple and that we're all criminals for wanting to be compensated for our knowledge, tools, and OE information we PAY for. That 4425 alone costs a few thousand on the cheap end.
You are right, we are in a heated building, on a lift. with thousands worth of tools and we pay hundreds a month for subscriptions. I've got 25+ years of experience and all of that needs to be payed.
Tail me if you think this is fair they charged me $11.16 for washer fluid $505.27 for I drive $25.28 for shop supplies hazardous materials $747.39 for labor .TOTAL$14409
Hi Dan, I hope you and yours are all ok. Another interesting fault finding video, it's nice to see someone find a fault that is not related to a recent repair, it sends me nuts when I fix a machine and then something happens and it breaks down soon after with a completely non related fault. The customer is always insistent "You touched it last so you must gave done it". Its nice to see it happens to other people. Regards Richard 🇬🇧
Hi Dan, I recently purchase a 2014 Audi SQ5, it was running fine until the other day this message was on the dash “Ignition lock defective” after I parked the vehicle it did not start again. I scanned. Code 03305:006 Engine start request wire - Short circuit to B+ Any recommendations. Thanks in advance.
How is it possible that only ONE wire, in a wrapped bundle of 32 wires, gets water inside its plastic jacket to the point of corroding BOTH copper and plastic jacket,breaking the wire in two, how exactly does that happen any ideas? edit 16:09 i think leaves+ vw's lack of care, laying that loom in a (future) pool of water+ (!!??), because somehow that 1 plastic insulation was nicked at the factory, almost looks like factory sabotage..
Dan I have a problem on a 2000 Ford 5.4 liter . I have a spark plug that's strip in side the cylinder ... You can't tighten it and it will not back out... Have solutions to fix it without talon the Head off ... Any tips would be helpful .. thanks
