This is the type of mechanic I like. He didn’t just throw the computer at it and go with what the computer says and leave it at that. He troubleshot and did process of elimination to get to the underling problem. Well done sir!!! 👏👏👏
Ricardo O'Connor Thank you!
Deo, you are an excellent mechanic and teacher. Your videos demonstrate a methodical approach to diagnosing problems, and your explanations are superb.
Peter Wells Thank you! I appreciate it!

Happy to see K Diagnostics doing another diagnostic and repair video. One of my favorite CZcams channels. May God bless this man with a long life and happiness. Great Video. Thumbs Up..
Richard 1 Thank you!! I appreciate you!
I have watched a few of your videos. and like the way you troubleshoot, diagnose and explain the problem, in an easy step by step method. You are one of the good ones on CZcams.
NIGEL HENRY Thank you!! I appreciate it!
You are the mechanic all people want!! nice.
WalterNut99 Thank you!
My wife has the 2013 VW Jetta 2.5 se, same issue. So far, thermostat and engine coolant sensor replaced, new fuse 50 added, new fans added but aftermarket part used (not OEM) I haven’t checked the other sensor you mention in this video. So far, when it runs all I’m doing is just removing the fuse to make the large fan stop once the car is backed to a parked spot, otherwise it will drain the battery. Your video is excellent! I don’t know where you are located but if you were close to me I would take my vehicles all day to you! Thank you for your expertise! God bless!

Thank you for an excellent video. I’ve been searching for knowledge on this problem, and you are clear, methodical, knowledgeable, and communicate well. Wish I would have found your video before all the other ones that were pretty confusing or useless…
lowstringc Thank you, I'm glad to hear that the video was helpful!
Would have been nice to see the signal wire reading with the fan plugged in.
I am binging your videos again 😂
Thankyou

Super informative video! Really great breakdown! A very good teacher. Thank you sir! I will be saving this to tackle my exact issue.
Tony Gomez My Pleasure!! Thanks!
Very very informative
I'm sitting with the same problem, and boy oh boy it's a pain in the neck...
I'm off to buy a new fan 👍
Jamarco Hull Thanks! Yes it is!
When the fan or any of the temp sensors are disconnected the Pcm can default to turning on the fan regardless. So disconnecting is not really the best way to test. Nevertheless you got it right and it’s generally a bad fan module.
Poway Imports Thank you for your feedback! this car was fixed after an OEM Fan assembly was installed!
Nice diag! you are a skilled tech!

Simplemente asombroso, puedo notar como logras aplicar muy bien los conocimientos de electrónica para diagnosticar este tipo de falla, tengo el mismo incidente en mi 2008 GTI, pero ahora tengo mucho mas claro que podría hacer para resolver mi problema, espero que eso me ayude. Thank you for your video!!!
Víctor Cabrera My Pleasure!!
Thanks for your video, very helpful. On my golf 5 TDI, I recently changed my fan that wasn't working, fuse 50A was broken. Replaced the fuse and the fan with new one that's not OEM and it's still not working. Checking voltage on the wires you show on your videos, all OK.. checking the yellow with multimeter and put it on Hz/Duty and there is signal about 5Hz. So, I suppose the new fan that is not OEM is the problem. I'm wondering why fan that's not OEM is a garbage like that
Ranto Nasoavina Raoelson Aftermarket components are not reliable sometimes, especially the electrical components!
Good one again!

Nice one Deo. You are my best diagnostician.
Ochuko Fryday W Thank you!! I appreciate you!
My polo had the same problem of fan running like this when the key is on after I unplugged the temperature sensor connected on the radiator. It stayed on even after i put the connector back in. But after I unplugged the fan connector, take the key out, put both the connectors back in, started the engine, the problem for some reason was gone😂
@bigbadwolf4392 oh really? that's odd!
Good job
Engineer Hussien Thank you!!
Hi Deo thank you for your insight and great video. I have a similar issue with my mk5 golf tdi 2005 model. The fans start running with key on. I checked both sensors and they checked out ok. Relay checks out as well. I had both fans replaced late 2021. Could you give me some light were to look. Thanks again.
lucky J13k check the wiring, if the wiring is good then the problem is most likely the fan module!
@@KITS_Auto_and_Truck_Repair I will look into it Deo. Thanks again
@@luckyj13k8 My Pleasure!
Thanks
Hassib This vehicle was fixed after an OEM Fan was installed in it!!
Thx

I think it’d be fun to work in your shop!
Che Kelley Thanks!! we do have fun in our shop fixing these vehicles, if you're not far from here, you should stop by and visit us!!
@@KITS_Auto_and_Truck_Repair I wish! I have a little one man shop in Arizona!
@@chekelley6861 Oh Cool! Sounds good!
Other demonstrated, that Fan turned on because of bad (AC) Fuse Nr1, located inside car, left side of front panel, under the cover. He putted a good fuse back, and fan stopped. Other demonstrated because of bad connection at Fan connector itself (Controller cable) he installed that cable, so it bypass connector, and fan stopped. Other told, without demonstration, that this can be caused because of AC pressure switch, some call it pressure sensor..
A.A Good!
Having a similar issues ...but I thought I read that if the temp sensors ..one or both wasn't sending a signal ...the computer defaulted the fan to on as a safety feature so the vehicle wouldn't overheat
Mr R. yeah! That's a possibility
I would never have replaced the cooling fan over that issue. There is other things that have to be checked first. With me if a load is on and working then why replace it?? Is the temperature sensor reading the correct temperature?? Is the relay stuck closed?? Is there a problem with the fan control module?? If the load works ok we have to go somewhere else. Thank you K
Richard 1 My Pleasure!! I like your thought Process!!
K, Great 👍 Diagnose but you fail to show Us the Fan Control Module I don't know if it integrated inside the fan or not but you failed to show us that Fan ControlModule how it works maybe next time !
svhebert The Fan Module is part of the first Fan
Thank very much, I'm from Vietnam. help me. wire from ecm sent to fan module, can the voltage be measured with a vom meter. If yes, what is the voltage when the key is turned on?
Dat Huynh it's gonna be difficult to check the command pulsed voltage on the fan control wire with a voltmeter, you should get a labscope!!
Hello, I'm writing on behalf of my friend
He thinks he has a similar problem:
He was driving his car (Golf VI 2.0 TDI) normally and it stopped working. At the repair shop they changed the alternator, but later on his battery heated very quickly so he needed to disconnect it. He also has the same problem with the fans draining the battery until completely dead. Do you maybe know what could be the problem?
As soon as the car starts it shuts off immediately and then the fans start working.
I already changed the alternator once and after 7 days the same thing happened.
@emin8107 the problem might be a temp sensor issue or wiring or etc.. it depends, I recommend you take it to a pro mechanic who can diagnose it properly!
Same issue ,my Fan gets direct on after the ignition, and ac doesn't work also.. can be the ac pressure switch faulty.. as soon as I clear the code . Blower Fan circuit 1. The ac clicks and run cold air.. what could be the issue.. coolant temp sensor reading is fine.. ambient temp sensor is also fine.
@iirohity Test your AC Pressure Sensors!
Ok thanks mate.
I have an 09 rabbit and mine was doing that
@LivingInRabbit this video should be helpful!
Hey .. I have a 08 VW Jetta . The cooling fans turn on the temp reads 190' degrees normal on gauges had code for coolant sensor ( replaced it ) is the radiator fan relay bad ? .. i know the coolant sensor sends signal to relay when car gets REAL hot to turn on fans .. where's the relay . Like your opinion ?
great cesars ghost these VWs have 2 temp sensors, did you check the other sensor?
@@KITS_Auto_and_Truck_Repair didn't know that ? I replaced the one next to where u put the oil ..where's the other one ??
@@greatcesarsghost the other one should be around the lower radiator or somewhere there in the engine bay! or you can look at the location of the second sensor!
@@KITS_Auto_and_Truck_Repair . What would the ambient temperature sensor have to do with the coolant temperature sensor ..
@@greatcesarsghost I didn't understand your question! what do you mean?
dang i found the cooling fan assembly on amazon for $80 but now im considering going with OEM. mind if i send you a link to get a second opinion? i would appreciate you looking.
just called vw dealership they want around $900 just for the parts..... im shocked at the price difference... if you have any reputable parts dealers recommendations i would appreciate your input, im nervous about buying the $80 part from china and i dont mind spending a little more staying in the states. thanks!!!
@9bytehub I would recommend you use an OEM fan!
@9bytehub I would recommend an oem part!
I’m having the same issue with my 2008 vw Rabbit! The check engine light came on showing Code P0480 as well, it’s saying coolant fan circuit one, which fuses should I check first before replacing both fans ?
Jason montez Follow the steps in the video, and make sure your temperature sensors are working well, or I would recommend having it diagnosed by a pro mechanic
hey did you get the code fixed? i have the same car same year same problem lol. any tips?
I had the same issue were the the big fan num(1) would stay on till battery dies , I replaced it with a Chinese aftermarket one it work fine for a week then i started doing the same thing ! Now i bought an oem fan and works good again I’m just worried it’s starts doing the same thing again
Btw I’m just replacing the big fan with the module not both
Any help ? Jetta mkv 2008
Hazem Elallaf I recommend replacing both of them because if the other one is shorted it could be killing that other one!
I have same problem in my 2014 jetta tdi wagon, I took it to the electrician, he told me computer motor has to be programed. the car has accidents from the front
Himide Hamada the fan module doesn't require programming, it probably needs to be replaced!
Awww man this is happening to my car as well i was worried my battery kept draining i was like wth! But my fan goes on and off on amd off on and off while the car is off so this does drain battery??
Alfonso Gonzalez Yes!
I have a 2007 2.5L Jetta. I bought the cooling sensor but cannot seem to find it on my vehicle
Danny G it should be around the thermostat housing!
Where are you located . Need to bring my rabbit to you.
Mole Man My Pleasure! I'm located in Dickerson MD, you can email me at Deo@calleva.org for shop info!
Hi,my Passat B8 2.0tdi 2016 when stop the engine the cooling fan stays on for 3 or 4 minutes and then stop is there any thing wrong with my car.? Thanks
Tahir Mahmood if it's not draining the battery, I would say don't worry about it!!
That's normal on those cars to cool off the engine.
I pressed thumbs down because I would've liked proof that the fix was a new fan because the computer was clearly sending a signal even though the fan wasn't connected and the car was off and temperature sensors disconnected which leads me to believe the computer is acting up and if you would've hooked up a new fan, it would do the same thing because the computer is still sending a signal
A Father To The Fatherless The activity that you see on the labscope screen is the computer trying to communicate with the fan module, which didn't communicate back, so the fan module was defective, this car came from another shop, my friend did the repair, after installing an OEM fan all was well...
I've had this problem for a while now. I'm so tired of disconnecting my battery 😩
@AudreysVortex I'm sorry to hear that, you should take your car to a pro mechanic who can fix for you!
@@KITS_Auto_and_Truck_Repair my appointment is on Tuesday 😁
@@AudreysVortex Ah Ok! Good Luck!

How to check on radiator fan on without vehicle
@Mohamed.Mustafa44 if the fan is out of the vehicle, you can send power and ground to it to see if it's gonna run!
Skoda rapid TDI outside fan not running how to check that fan controller type@@KITS_Auto_and_Truck_Repair
I have a Golf 6. The fan turns on immediately when the engine starts. Where is the problem?
@kokokoko-jr7sj get it scanned and see what trouble codes you have!
Pls where you are

Ecu ???.
@user-wb2pm1rf4r watch the whole video to find out!
My fan stays on only with key on
Lee Stewart that could be normal!
