13:42 - supplier issue with a pretty huge bill I bet cause the owner got a loaner too.
And now they will try to find the employee who had built the cable harness and who had checked it at the end of the assembly line of the supplier.
It is a pretty big issue if that happens again across europe from time to time or even does work in the beginning and might become loose 1,5 years later.
Then a lot of parts can be replaced before someone gets close to that error.
But why did the diagnosis throw out this weird error message (short via plus or so) cause you had not spoken about it and why it did not help at all or did I miss a part ?
8 out of 10 of those problems seem to somehow be down to human error.
Over thinking the job.
But sure, that's just it.😩👍
And I hope that you told the owner of this vehicle for this bill brought it to Volvo and had them pay the bill or at least pay them back you know that's not right
I notice that you stuggled a little with English. Spare a thought for those of us that don't have any alternative because it's the only language we know.
@@andyvitz Volvo??
The bloopers are always funny, BUT the big thing I get from it . . .
I really appreciate you taking the time to make the English videos!!!
I get so much from them.
Thanks Dan!
I never realized until now that Dan is in the Netherlands. I honestly thought he was in the UK, it does explain the Dutch language settings in most of the cars though.
@@Hybris51129 Dan speaks great english but could never be mistaken for a brit. Not even for a brit imitating a dutchman. I think thats a good thing.
Beautiful explanation and beautiful video👍
@@Hybris51129Not far from the UK😉
@@Hybris51129From the UK but with only left hand drive cars? 😅
Dan is now a VW field engineer. Next year he will be Senior VP of QA
Naaaah Dan knows what he's doing that's not what they are about.
Dan for president!
@@geroldvandegoor6481 I think Dan's country has a Monarch.
Wait...VW has a QA department?
@@rimmersbryggeri Indeed... King's day was celebrated a couple weeks ago. We get a day off from work, sooo.. long live the king!
When Dan uploads you know its going to be a good video. 👍
I wish he upload daily. 😁
@@petergrunendahl8799 Now that would be good as his videos are really informative.
I just wonder how fast he had to guess that the problem can be in some connector somewhere. I swear, there are lots of connectors. Maybe something was let out in the video, I mean the moment when he decided to check all relevant connectors, starting with the ones at the compressor.
Such a problem could be anywhere.
It's also important in such a case to understand what was tested at the factory. I don't think they can wait to see if the cabin cools down!
Everything can happen. I have myself assembled Volvo truck gearboxes long ago, and know that it's not possible to test every little detail when the gearbox is completed.
Thanks that is a great compliment.
@@leiflillandt1488you are right! Could have turned into a very long video. What if the loose pin was on the control panel side?
I started at the compressor because of the faultcode but it could have been anywhere really
The only problem with this channel is ? you don’t get enough blogs quite often but when it comes, you know it’s full of gold and diamonds.Thank you for sharing your skills and experience.
Its a pleasure, thanks for your great comment
Customer - " Hello, I was in before with an AC problem and you could not find the problem, it is still not working. When can I bring it back?"
Service writer to mechanic- " It's that guy with the AC problem, he wants to bring it back"
Mechanic-" Oh No- tell him we are booked up for months"
Almost all brand
Dealerships in the Netherlands are backup up for months. Its been like that for a while now
@@Vespastendert Same in Belgium. Three months to get a service appointment where I live. Crazy. I think it's because of the very low quality cars they pumped out in the covid period.
@@Vespastendert Same in Norway. 5 weeks if you want a service, up to 3 months if you need a technician for a diagnosis. But we try to prioritize AC and safety complaints.
Believe it or not same thing happened when I contacted Dan's garage. It had a problem no one could find, so I thought Dan will fox this for sure. But his colleague told me they can't help me and I had to wait like 2 or 3 months minimum.
@@RespectedDesperado Dan is probably backed up because dealers are too busy trying to figure out how to fix all those diesel cars with the tricked up software.
Dan is now the Head of quality control in Volkswagen
🤣🤣 No thanks! I'm busy enough as it is!
Dan is an inspiration to anyone who has an interest in fault diagnosis. I spent my career working on commercial heating systems and trouble shooting systems installed by others, its the most rewarding thing to do.
Thats also interesting! I recently installed a Automated Pellet stove at my home. Nobody wanted to do it here because most people use gas heater and nobody is really experienced.
I can now heat my house with my heatpump, gas central heating or with a pellet stove😂
U are the KING when u want to buy a new car at the dealership, but when U want service....even under waranty....U are a simple peasant...and goodluck to you.
Yes sometimes thats the case, it's sad
I'm smiling all the time when you tell us: Let "US" diagnose it "TOGETHER".
Yeah, I was working real had ... watching you. 😂
Thank you for another diagnose lesson.
Regards from Belgium
I knew what the problem was going to be just not where it was.
Ha ha Peter, i really appreciated your help😂
Ik zou je een factuur zenden…😂😂😂
I saw that bad connector the first time you back probed and the system started working. I’ve seen those intermittent connector issues often, but rarely in a new vehicle. But it happens.
Good job Dan. As always, you fixed it again!
I also thought it might be that connector but don't forget that Murphy controls all intermittent faults.
I took me some time to realize that🤣
Back probing !!!, the best way to damage a waterproof connector.
@@jasoneldridge4738 Get yourself some needle probes (or make some with 30awg insulin syringes) and if you still can't sleep at night, smear a bit of silicone on the area.
Dan, you are the best mechanic here on RUclips. In my opinion, you are constantly solving any problem. I enjoy all your videos
Thank you very much but there are alot of very talented technicians here on RUclips!
When you know and understand how an electrical and mechanical circuit works, it makes it easier to troubleshoot.
Most intermitten problems, my last test is to shake, twist and gently pull on wires.
Good job Dan 👌we fixed it together again. 😁
You are right, dont forget temperature changes!
@@Diagnosedan Yes, expansion and contraction, I will remember that one. Thanks Dan. 👍
Dan you are genius, you can even find a hidden ghost in the car with your closed eyes,,,,well done
Thanks for watching!
About half a year ago I got a two year old Peugeot 5008 to fix an intermittant AC problem.
It was cooling the cabin just fine when driving but it wasnt working while the car is moving slowly in a congested city traffic.
The problem was, of course, that the radiator fan was not working.
But there were no faults on the fan, and no faults at all in ECU, BSI and AC modules. It was running the Fan test just fine, also the fan was working perfectly, when the engine coolant got too hot.
But when you turn on the AC, the compressor clutch engages, pressure valve gets controlled, pressure rises up and as the fan doesnt engage, it overheats, reaches overpressure and the clutch disengages until after a few minutes it cools down a bit, the pressure falls down to acceptable and the cycle continues.
The problem was found after a long and torturous diagnose to be in a software of a BSI module, which is a central control unit of a whole car (Peugeot/Citroen branded). It is not in any way responsible for the control of the fan, but it is responsible for gathering some of the information for AC module and it also kinda connects the AC module with the engine ECU, that controls the fan speed. Somewhere in between that request for the fan was being lost.
It was either:
1. Made this way and left the dealer completely new with a software or a module configuration bug.
2. I found in the module identification data, that the current software release date was newer than the manufacture date of the car. So the soft was probably updated at the dealer, when the owner went for oil/service/inspection. The date of the last diagnose in the diagnose history was a winter month, so it probably went unnoticed for a pretty long time, as the AC was not actually needed in winter and on spring it only helps to demist the windshield faster. So it may be unnoticed too.
It was fixed by updating the software of a ECU module and BSI module. Factually, I wasnt really sure it would help, I just tried it as it was kinda last resort as everything else was already tried.
Luckilly, PSA (Stellantis) still gives the ability for independent garages to access the software updates.
Problems that can be solved by a software update are nearly impossible to find! Great job 👍👍
Always remember to check the basic . Don't jump ahead. Thanks Dan this video help me to remind myself to always check the basic stuff first.
Thats right!
thanks for bringing us along and not giving up and trashing the footage, I know all too well how hard it is to try and keep going while creating something decent to share so others can learn and benefit. Thanks for the efforts once again and nice find!
Thank you very much!
1. Two months till an appt? I don’t need AC the dealer has already frosted me!
2. Intermittent is real world thanks for seeing it through!
3. Seeing no pressure change I would have mistakenly swapped the compressor. Great advice mechanical problems don’t fix themselves!
Mechanical parts usually dont fix themselves 🤣
I think i would probably have recommended a compressor too...
Yes! A new video. Man I would love to work for someone like you, Dan, you're a credit to tour field.
You could do all the work and i could watch for a change! 😂😂😂
@Diagnosedan honestly, I'd be more than happy to do that. That's a right deal to gain your knowledge!
Certanly the best diagnostician that I have ever seen on RUclips. It is a pleasure watching you chase these pesky problems. Cheers form Slovenia :)
There are alot of talented technicians on RUclips!
Thank you Dan. Im always learning something.
About 1 1/2 years ago, i ran into a similar situation with my sisters Sonata.
She was quoted $3,000.00 to fix the system.
Just like you did. I went step by step. I was stumped as to why the ac system was not working.
Just like the VW ac Kornpressor. The ac clutch was working. Until i found the regulating valve issues. I ordered a new One. Pumped the system down. Replaced the valve. Cost $25.00 plus shipping.
Plus the new refrigerant. System worked as it should. She drove it home and not anymore problems.
And another as ac system problems with my daughter Toyota sienna. Ac didnt have any issues. On the way to work, they had an accident. Car got fixed. Then ac system issues developed.
Since it was accident related, she took the car to a shop for diagnose and repairs.
Shop said, bad ac compressor. They replaced it. Ran good for a while then intermittent ac system. Got cool for a bit and then no ac. Off and on. The shop wouldn't warranty the work. They wanted to replace the ac compressor again.
So i took over the diagnosis. No codes at all.
I downloaded wiring diagrams and read the system description.
After i read the description, i asked my daughter, what does the temperature display for outside temp ??
She said its reading below freezing?
I got curious.
I found during the repairs. The shop had twisted the wires and just added black tape. And left it hanging. The sensor is located in front of the radiator.
I admit i did buy a radiator cooling fan module. This was out of haste because, this issue was in the middle of summer and my daughter was on a trip.
I ordered a new pigtail and repaired the connection using solder.
Note: If the ambient air temp starts to drop and goes below freezing. This will shut down the ac compressor.
Because of the bad previous repairs, the ambient air temp would work intermittently.
Then the compressor would work.
It's great you were able to fix those problems yourself! Most technicians get very limited time to diagnose problems, almost no time to study the system and do all the necessary checks.
Great vid, Dan :) I am a little disappointed that the dealer couldnt find a fairly common factory fault, that they didnt even have to dig for. Ive probably seen this more on VW/Audi than anything else, here in Canada. Thanks, again!
_"a fairly common factory fault"_
Is this a known issue on VW AC compressors wiring harnesses?
@@ferrumignis to be clear, im referring to backed out pins in connectors being a common fault in new warranty electrical repairs, any system really. And that this one didnt really take a lot of digging to find. Thanks!
In their defence.........it's hard to find a fault when its not acting up.
@@Diagnosedan Absolutely agree. However, I think we can expect more than average from a Manufacturer licensed Dealer, who then asked the Customer to wait until they didnt have more profitable work on the go, to attend to an issue that didnt end up being overly complex, and would have been found in the first handful of troubletree steps, had they bothered. Dont get me wrong, I appreciate the dealer service making us look like superheroes out here, but its just not right, its a new car.
Love your content, Dan :)
Would hate to think how much parts the dealer would have changed before they sent to an indy garage.😂😂.keep up the good work, Ted.👍
Dealer fix: replace ac compressor (3×times)hvac ecu, all ac lines and finally fixed by replacing entire engine wiring harness...😂😂😂
@@mrblonde2013 That sounds about right, and the vehicle would have numerous rattles and badly routed wires afterwards.
I know that Dealership technicians need to follow the testplan. If ODIS ( the VW factory tool) tells them they need to replace a component they have to do so it in order to claim waranty
Woow, with that clutch kicked in, I really thought the AC pump had an inner mechanical failure. Again a good lesson Dan, thanks!
That crossed my mind 😉
Love the bloopers Dan ! ... but I always come 'a running when I see your videos post ! ... thanks for the great DIAG jon o in idaho
Thanks for your great comment its really appreciated 👍👍
Diagnose Dan did it again🙂 Those sort of faults can be infuriating to find, my wife's 2015 Subaru WRX had an intermittent AC fault and the dealer couldn't fix it after 3 separate visits, I did a Google search and found that there was a "known" fault with compressor clutches, too much air gap in the clutch fixed by undoing one 10mm bolt then removing the outer part of the clutch, remove a shim then refit, once the air gap was to spec the AC worked perfectly, it was a less than 10 min job requiring no parts yet the dealer couldn't fix it because they said that it always worked when they tested it.
I went thru this issue with a 90s Ford 4 cyl. Dealer wouldn't accept that was the issue with it🤷♂️
Your wife has a good taste when it comes to cars.
@@moestrei Unfortunately she broke her ankle so she couldn't push a heavy clutch anymore so she had to sell it, she did look at an auto WRX but didn't like the CVT trans.
If a fault is not present its quite hard to find, thats why i always start out be confirming the customer complaint.
@@Diagnosedan Agree but if the customer complains about a fault at least 3 times its reasonable to assume that there is a problem so it warrants looking a bit closer such as taking the car for an extended drive to confirm the fault. The dealers "testing" of the fault was inadequate.
I wish i was half as good as you with auto electrics Dan! Keep the videos coming. I love them all.And learning at the same time.👍🏻👍🏻👍🏻
Exactly
Thats great to hear!
Another car fixed! Thanks again for your knowledge sharing, Dan! On a VW Passat CC i had the auxiliary water pump connector swapped with the regulating valve connector of the AC compressor by the mechanic. Really hard to diagnose since both connectors were the same color. PWM measurements were very handy back then. Impressive job.
To be honest i've noticed especially on Volkswagen that some connectors are interchangeable. I've already diagnosed quite a few with swapped connectors. Sometimes shorting things out and resulting in damaged control units.
If i was in charge i would make sure thats wouldn't be possible!
People slate the mk8 platform having problems with assist and other electrical problems and haptic buttons. But I've had mine for 3 years now done 27k miles and I've had not one problem. I had an assist light come on once and that's whem it was -2 and covered in frost, soon as it thawed out it was fine . I love my mk8 and I've had every golf from mk3 to mk8

Thanks!
Typical V.W. low quality vehicles needs a non-typical car mechanic. Another outstanding diagnosis. You are the gem of the auto industry ! 👍
Right, because no other car brand has ever suffered an intermittent fault from the factory. 🙄
A high quality vehicle requires a highly overpaid Technician/ Certified to work on them. 😅😅😅
I know right. Ford at least ships their new trucks with oil pan leaks so rather easy to see their incompetent manufacturing.
I heard Teslas are fault free and their self driving mode never killed or even attempted kill anyone.
I heard Teslas are never broken nor panel gaps and perfect paint jobs. And in their self driving mode never even tried kill a person or attempted murder biker. Amazing.
Well done Dan. Nice diag. It goes to show you that the dealers these days are just interested in fast in & out jobs & could really care less. God Bless & stay safe, TMP from N.J.
Its all about the money 😉
Common sense isn't very common......! Always enjoyable and entertaining. Thank you for your patient, step by step analysis.
No need to ever bother going to the dealer. Having you explain these things is golden....! Professor Dan is the Man...
Thank you!
Interesting diagnosis and resolution of the fault. Thanks Dan as always.
And thank you again for watching!!!;
Great video; like watching your thought process and approach to fault finding.
Thank you!
Your videos are so therapeutic. Keep up the good work!
🤣👍
You deserve congratulations. I am an engineer from Corinth, Greece, for many years in the profession. I follow you and admire you. You have managed to manage the diagnosis part with a wonderful Way.also you definitely have deep knowledge of this difficult subject but also an extremely understandable way of presenting.I just admire you. be well, George engineer from Corinth Greece.
Thanks George!
Patience.....its so valuable.
I wasn't as patience when i was younger🤣🤣
Great Video. You spent time diagnosing the issue. As you said the dealer said nothing wrong but it was. You should get your client to send the bill for your time to VW. If the dealer had investigated they may well have replaced the Air-conditioning pump. Always know I will learn something when you post a video Dan. 😀👍👍
Unfortunately there are strict protocols to claim waranty.
“Now it’s new new.” Nice! Nice! Dan! Dan! (Love your work! Best wishes from Florida.
I love Florida! Just a little to hot in summer for me🤣 I couldn't get any work done🫣
Looking good Dan - and congrats on a difficult fix. You fooled me badly with this one - was betting the compressor was bad, which shows how little I really know about A/C stuff.
Thanks for watching!
I'm lucky. My 2016 VW Golf MK7 1.8t is almost 9 years old and I have had zero mechanical failures so far. I'm running a stage one tune and even the stock clutch is holding the increased power.
Thats awsome, of course the majority of cars are just fine and wont make it on to RUclips 😉
love those bloopers 😋...the video itself really has been an eye opener...."recognize the pattern" I would call it 👍
🤣🤣👍
Another great video, I hope the client can show this to the Stealership so VW may reimburse him/her for your refrigerant and labor.
Unfortunately they wont
Great video as always thank you for all the knowledge being shared with us. I was working on the golf8 project sometime ago and I wasn’t expecting to see that car in your videos anytime soon ha ha.😂
🤣🤣🤣
Brilliant fault finding! Thanks for all your patience doing this job & great video!!!
Thank you!
I've serviced medical equipment in the past, and have found similar intermittants. This is kinda scary, but the faults showed up very early in the equipment's usage. So, faulty pin fit/crimped connector flaws can and do happen in all types of electrical/electronic equipment. Good diagnosis Dan, excellent work!!
Thats an interesting line of work, i guess you ran into quite some strange faults!
Dan is an very secure person, for the bloopers are priceless.
Love it.
🤣👍
Nice video and great catch on the loose pin in the connector. I’m glad the A/C drain missed the scope and didn’t fill it up with water. That would have put a crimp in the diagnosis. 🤣🤣
Yea that nearly missed🤣
A simple little connection and no A/C. Good one Dan.
Yes it mostly is simple once you found it🤣🤣🤣🤣
Great detective like always, it took Dan to sniff out the problem.
Thanks for watching
Again great fix. When you back probed the connector and the AC started working for me the connector was suspect no1. You confirmed it.
Smart thinking! It took me some time to realize! 😂
Small things allways make the diffrence..good work Dan,you are an possitive example for us. Cheers
Thank you carlos
Nice episode Dan!!!! You developed my passion for auto repair! I changed three closing modules on the driver's door on my car, which after two or three months no longer indicated that the door was open! I changed the responsible connectors (pins 7 and 8) in the plug and everything was solved, thanks to Mr. Stuzman, who presented everything that the door closing module contains. Keep growing and good health!!!
Thats great to hear!
Fault code showed fault. A bright light in the plug face will show height of connectors. A lot of people miss the wiring and especially the plugs and connections. Vibration can cause mechanical wear on pins and plugs and give intermittent faults as well. I have heard “I replaced the Sensor then the ECU and it’s still broken what else could it be. It is the thing that causes most faults the wiring and connectors! Good diagnostics Dan once again. Brand new wiring can be incorrectly assembled and cause problems, I have found a few where the connectors where clamped on the insulation and not the wire, incorrect assembly of the loom and when assembled forcefully, push backs in connectors. Nice feeling when you find the culprit!
It sure was a nice casestudy! Thanks for leaving a comment
These kind of problems are hard to find sometimes, nice find because you stuck with it!
They can be very hard to find and realize that could have been a loose pine anywhere in the system. Even behind the control panel underneath the dashboard
Very patient and skilled 🥰
Thanks!
6:22 We have to admit that the fault description of the system was a very good hint
Yes indeed
yet another excellent bit of investigative diagnosis! Dan fixed it again!
Thanks for watching!
Thank you very much for another wonderful video thank you for the insight knowledge of diagnosing a compressor problem. I guess this problem would also fall on all different types makes and models of all other vehicles even as well as North American vehicles thank you very much for your time and effort 10 out of 10.😊😊😊😊😊😊😊😊
Yes it could have happened on any brand👍
Thanks Dan I love it when you point out every aspect of the diagnosis and the fix do you ever think that the dealers really look or are capable of tracing faults Dan you are the man !👍🇬🇧
Thanks for your comment!
The wires for this regulating valve used to break near the transmission on older VW models. Funny to see the still use the exact same system on the newer models.
Thanks for leaving a comment! Its appreciated!
Dan, excellent diagnosis. Great job.
Thanks!
Brilliant video as always. Your overall knowledge is phenomenal, the way you are able to break down each problem into simple methodical steps that definitively rule out issues as you go along is brilliant. A joy to watch 👍🏻
Thank you very much!!!!
20c is chilling temperature in my country coz today is 45 outside. I like to work on my cars and somehow always avoid doing A/C work. I always thought that A/C work is complicated than all other work combined. This video of yours actually helps to understand how gauges work. I will try to diagnose problem myself. Thanks and a big fan.
Ac is simple most of the time.....btw 45 degrees? Where are you from? Living inside an oven?🤣🤣 That would be to hot for me to work
@@Diagnosedan Bro u just made my day. I am from Lahore Pakistan and today temperature is 47c..
Love the bloopers mate your work is exceptional great job 👍🦘🇦🇺
Thank you!!
The test plan in ODIS for this fault code starts with??? N280 (T2fi) connector check. If the VW service had gone through the guided fault finding (GFF) from Odis, this car would not have reached you😀
You could still easily have missed the issue even if you checked the connector it looks fine as long as you dont pull the wire
Dan I had no doubt that you would solve a problem and this is one of those frustrating problems, Dan you are a champion
Thank you!
I have learned a lot from Diagnosedan after i returnerd to work in this field like an electrician and Diagnostician
thank you so much DAN you are the number one.😀💪👍
Thank you colleague!!
Common sense Dan fixed it again! You the man!
😁😉
I've been a fan for a while. I have a 2004 Amerikkkan Golf 122 (2.0). The a/c compressor clutch will not come on. The dealer charged me $1,300 to find out the problem. They said the a/c module was bad and they wanted another $1,700 to replace it. I said forget that and hot wired it. I now turn on the clutch with a second defrost button on the dash.
😁👍 If it works for you!
What a 'cool' video. Nicely done - no parts required. Always look forward to your videos. Thank you for sharing with us.
It was cool in the end😂😂
Toujours d'excellentes vidéos et de la persévérance dans ta recherche de panne. Merci Dan pour la qualité de ton travail.
Merci beaucoup
Always enjoyable to watch! I have a car that had an intermittent fault. It turned out to be a partially fried wire. It took 50 hours in the shop to find it out 🙂
That is messed up!😬
🫣🫣🫣🫣🫣 did you pay for the full 50 hours?
I am always looking forward to see your videos. Very clever.
😁👍
Fantastic fix Dan, love the video 😊👍👌
Thank you
The vast majority of VW wiring harnesses were made (for decades) in the Ukraine. They had to move production and it takes a while for the replacement factories to achieve the same level of QA. EDIT: fixed minor typo.
Interesting!
Cool you fixed the problem. Fair quality control at Volkswagen plant. I hope the dealership mechanics will see your video and learn to check something small like a loose wire connection.
In most cases Dealership techs have to stick to a pre defined test plan, if they think outside the box they can't claim waranty. If ODIS ( the VW dealer tool) tells them to replace a part they have to or waranty is denied!
@@Diagnosedan l see. I knew a neighbor son that was a young mechanic at a local Ford dealership in the 1980s. He wanted to do a great job fixing customers cars. The other mechanics told him to do a poor job and didn't get along with them. He ended up working in the parts supply department. This was in Connecticut, USA.
Thanks Dan , Yet again enjoyed the process watching you resolving the problem. 👍👍
Thank you
Another great lesson from our sensei keep it up Dan 👏 top class workmanship
And thanks for watching again!😁😁😁😁
Great one as usual! Thanks for simplifying complicated things. And I'm super jealous of all your tools!! 😂
Thank you!
Haven’t seen this guy in forever
Happy to see me again? 😂
Good Job Dan 👍, it's been a while, I was also hoping that at the end of fixing the connector issue, you would have pulled out the connector again and see if we have same fault code or a different one to give us the confidence that the intermittent fault was only from the connector alone. Weldone
It was😉
This is exactly why I got in the habit of checking electrical connections when looking for faults and failures in car components,starting at the problematic component and working back to the control unit.
😁👍
I have owned several VWs over the years and none have had A/C systems that didn't require repair within the warranty period.
I have owned several other marques that I have driven for over a decade that only needed an occasional top-up of the refrigerant to remain ice cold.
Thats unfortunate to hear.
A real nice fix. These problems are always hard to track down. I never work on cars, but have had similar issues and worse, broken wires in the control wiring from a sensor on a packaging machine.
Thats an interesting line of work! I can imagine all that can go wrong. Our shop is next to a factory. One of the machines kept shutting down. It turned out for safety reasons nobody was allowed near that machine and this was monitored by a laser. If the laser beam was crossed the machine would shut down. It turned out it was because of flies flying through that laser beam😂
@@Diagnosedan Yes had problems with Sick (the manufacturer) safety curtains stopping machines due to being too sensitive to such things. Never saw the laser variants though. Been 15 years since I last worked with them, happily retired now.
Think this is the first video where you have described a fault as “challenging”! Brilliant stuff, although this time i had also concluded about 5 secs before you said it that it must be the connector. I thought it was because you were creating an Earth return with your probe and that the Earth wire was broken rather than a loose connection. Already looking forward to the next one 👌👌
Smart thinking! It took me some time to realize that🤣
@@Diagnosedan don’t think it’ll happen again - your job is definitely safe 😂
You are the best mechanic I've ever seen, I wish you lived in my city
Thank you very much! What city is that?
@@Diagnosedan Sydney, Australia 🦘
@@wickedwabbit7365 i was in Sydney last month, loved it!
You now have a truly hybrid system👍. I'm qualified to install and design ASHP but would never replace a natural gas boiler with one, there are some benefits in having the gas boiler and heat pump working together in a hybrid way, but there's a long payback period in the UK
😁👍
Always a pleasure to watch your videos. Take care
Thanks!!!!!!
Typical problem with electrical contact, yes. Bad cable termination, bad plug itself (broken plastic parts), wire snapped and so on. Goes on and off any moment.
My Crafter has problem with AC from the very start. It is working, but only on full power. Even if it is 20C outside, not 40C and bright Australian summer sun, in this condition it must freeze everything!
Its definitely not a compressor or refrigerant problem as pressure is ok and rear ac working good. Its something with temperature sensor/control for cab ac itself. Will investigate with dealer, anyway they have to do lot of work wich was simply forgotten on factory.
Wow thats unfortunate 😲
@@Diagnosedan this is Poland! 2nd gen was specially ordered, contracted, paid, waited for more than a year... and when van arrived from the other side of planet it appeared they did not installed it. Waiting for parts now, VW collected almost everything already except silly crankshaft pulley which does not present even in central warehouse.
Thank you very much for sharing these breakdowns. You are the best Dan.
Thanks thats really appreciated
That was a great diagnosis Dan well done !
Thanks!
Thx for a new video! I guessed on the connector right away when you back probed it the first time - had the same issues on old computers - the power connectors for the harddrives often had the same issue!
Thats interesting to hear! After editing the video i watched it and than it indeed was pretty obvious. But at the time it took me some time to realize 🤣
@@Diagnosedan it is much easier to get the clues when you are only watching - not filming and doing the work!

Moment dat je een werkende AC had met insteken verdacht ik ter plaatse de steker.
Oud VW monteur hier, ook mijzelf al eens de puistjes gezocht naar een soorgelijk probleem (losse pin in een steker)
Scherpe observatie! Het duurde bij mij even voordat ik het verband zag🤣
