Wow this is just fantastic not only did you take the time to fault find but you made the huge effort to film it and edit it and then post it a big huge thankyou 👍
If you were used VCDS (comunication error with module) or just look at door wiring diagram, you probably find the faulty module in less than 5 minute. But it is interesting how you test all the possible points where the problem can be. Very nice video.
I cant believe you didnt mention the fact that after pulling the door and the lock to pieces that it turn out to be the issue. I diligently followed your video step by step pulling the car apart as i watched step by step. Grrrrrrr
Thanks for this, I have the exact problem on mine, I was wondering if the left module would work on the right side to test it, now I can try that to verify a bad one. Lots of useful info in this video 😃
An interesting repair =D Also looks like it was a nightmare tbh lol! I would take taking a car to pieces like that - knowing my luck it would start raining, or I would drop a part somewhere...
have the same problem with passenger door and i was thinking about the look as well , but the window is not working only from driver door , but now i know where to look 1st and test , cheers pal
Years ago a circuit had several transistors, resistors and capacitors placed on a PCB making up an entire product or component costing around $25, and not long after that an IC replaced umpteen transistors resistors and capacitors all in one package to make up a component doing a crap ton more stuff and yet still costing around $25, and here we are today with modules made up of several IC's and their supporting components and well the cost is still around $25 bucks.. Just goes to show how we have progressed.. APU I dropped a Like their mate..
Nice fix, brought Ivan at Pine Hollow Auto Diagnostics channel in my mind as he too often tries to repair cars with "no parts required" -method, aka. trying to fix the root cause instead of just replacing expensive parts :D
I'm a career flat rate mechanic. Live in New York worked at chevy Honda and Toyota. I wish all door skins were removable. Would have saved me a lot of blood sweat and tears in the past.
Excellent video Vince. Back in the 80's and 90's UK advertising convinced people these were good cars. Actually they aren't, the sound of a door closing is not a sign of quality 😐
Oh god, this brings back horrible memories of trying to get the door handle off mine to do this job. Didn't matter what I did it was stuck good and proper and ended up hack sawing it in half and getting another one. It just would not come off as I had seen in countless videos.
hi i suspect the 6 wires in the door are gnd, 12v, can hi, can low, speaker+ and speaker-. can you try diagnosing the can wires on the pcb eg not connecting to chip? it could be a bad solderjoint
Some VW make "accurate" use or the motor on the window mechanism, since it used as position encoder (by counting ripple pulses) and to measuring the current to trip the pinch protection system. Putting the new board with the other motor could (if this was the case) make this functions to missbehave (pinch protection triggers at different force of when the windows reach the end). Unsure of this would apply to the GOLF. Usually the system that have this features do the actuator learning each time the battery is reconnected to calibrate the windows.
My Audi A4 has similar problems with rear drivers door not unlocking , obv thought it was door lock or solenoid but now gonna check window works first and whether it recognises the door open on the lcd display so may save me some time , fingers crossed so this footage may be invaluable to me ..
Fiat stilo, headlight bulb change you need to take off the front wheel. Airco was giving hot air instead of cold. Cause bad servo motor. To fix it the whole dashboard must come out.
Thank you very much for your video! Mine door, just as same as this golf mk5, rare left, doesn’t lock too. But i can use the window. Could it still be the problem with window mechanism? I mean, maybe it will provide good signal to window but fault to the door? I had rewired all the wires, tried to change the locker, but the locker was working. Maybe this is solution for me too😅
Good luck with all the springs. As an auto electrician for 25 years, I've done my fair share of these on most cars. The German cars are by far the worst to work on. 💪
Front door does not have airbag there have sensors and use m8 spline bit or disconnect the battery to reset as my golf plus door did not want to open and found out has 9 fault code
Vince, you won't be the first or last person to make that mistake of taking the door completely apart, rest assured of that, the thing that you failed to do here was to check all the electrics in the door first it would have given you more of a clue. so you would have found the window wasn't working also, you done right to check the wires from the door pilar to the door itself, as is a common fail point. and it is common to run a cable to the shortest length possible, which would mean fusebox to the door, and the closest thing is the window winder as it is electrically powered. but also the window switch could be faulty so not 100% reliable unlike a mechanical winder, but then that wouldn't have the window as a fault either, so can be some out there that have a simular problem but with mechanical windows. so fault finding is never easy.
it is kind of like saying "my pc doesn't work, I changed out the power supply, as I believed it to be at fault" well what about the fuse in the plug?!!
i have VW gti 2008 2 door, i have the same probelm with the driver side door, the window goes up and down, but it wont lock or unlock with the remote. even if i press the lock button on the door itself it doesnt lock, but the unlock button works. i was working on the window the switch the other night and i found coffee all over the connector that goes to the window switch. when i press the lock or unlock on the remote the little light on the door flashes, please advice me what do you think the problem is ?
Would this also show that the door is open all the time when its closed? I have no working window, not locking and door shows open all the time. Its somewhat intermittent. MK5 schpertzvagen
That dangling door :( Was it hooked on something or was it literally hanging by the wire that powers it? Also why didnt you try to swap around the suspect chips, given that you had a "donor" (lender?) board.
I bloody HATE doing maintenance on car parts from the last 10-15 years. I wonder if the right to repair law will help with this too? Has to be better than Haynes 😂 Keep up the good work fella and stay safe.
Never seen a proper door you can take the skin off my cars have mostly been Renault my twizy can do it buts its so you can change the colour of the car easily, last car I had to get the lock out it was through the holes on the inside of the door it was a nightmare
The module in the window regulator is the door control unit. It’s just integrated into the window regulator to keep the assembly process of the door simpler. The electronic modules in the MK5 Golf are pretty simple and easy to diagnose. Get a cheap 20€ knockoff vw scan tool, those save a lot of time and are able to diagnose a faulty or non-communicating door control unit. And: The side-airbags are integrated into the b-pillar.

I am not a mechanic by any means, but I have done my fair share of working on cars. I have never seen a car door that has a removable exterior panel. I learn something new every day!
Same here. I have worked on loads of cars new and old but no VW's. I have never seen an outer door skin that just unbolts. Recently I had to fix the central locking unit in the door on a friend's Hyundai and it was like performing keyhole surgery.
I've been working on cars for 25 years and I have never seen a door come apart like that. Normally for access to the lock you just pull the interior door card.
The Golf mk5 was overkill in engineering, I think it was during the Martin Winterkorn era so not really surprising. I read somewhere that the build time for one car of the mk5 golf was 3x longer than the equivalent size car from other brands, say a Focus for example. Bloody nuts.
I can feel your pain on this one, getting those door skins and cards off is not a fun job! Excellent diagnosis as always though, and I'm certain it will help others out with the same problem! 👍
this was great, and outside of your normal content, which I appreciate. I know my voice is only one out of your nearly 5k subs, but thank you for this, it was entertaining and informative.
Vince make sure you repaint any of the bolts that hold the door skin on if the paint is scraped off as they rust like there’s no tomorrow after removing them skins
I think you do yourself an injustice Vince, we watch your video's for the entire faultfinding experience and you didn't make a mistake in my opinion you learned how a door mechanism functions. Thanks for another great video.
That is a thing that has been around quite a while , lots of different scenarios, with head bolts and camshaft bolts , camshaft push rods and other engine related parts to keep them matched up . Its a fail safe that even experienced mechanics use
@@doslover I used to work on bikes and cars , the reason for keeping the parts like that is because they have worn to each other , think of it like disc pads and the disc, they all wear different on each wheel so you keep them matched to each other ,
Video has great value mate. Saves us all ages of time and really shows A. How to take door skins off and B (not being smart) To check first tings first. Overall a video to save for many reasons and honestly we all get a pass on having to do all you have done. You've added a saturday to everyone's life who watches this with the same head scratch. And all Mk5's seem to give this head scratch. Cheers
Made the mistake once putting the door bolts back in the wrong place (different sizes). Especially on my MKV/MK5 VW Jetta. That is a very common fail item, done a few myself. The door switches (windows & locks) are also a common fail. Typically the solder joints go bad on their small PCBs. This past year I ended up just replacing everything. Still love my MKV/MK5 though. A very reliable vehicle.
Yeah, I think there were 3 different sizes on the door bolts! Interesting to know the failures are not just on the VW Golf. Apart from the door issues, that car has been very reliable. Cheers Shawn 👍👍
Befors u do this try to take out that small rubber seal from inside the Door drill a small hole on top of locking actuator and put a squart of wd40 in that hole. That fixad the problem for me takes litterally 2 minutes:) Mine would get stuck in locket position now it works perfekt. If i did it with my few tools anyone can do it. That rubbear seal in the door is right om top of the actuator so it’s easily accessible for the drill and the hole is drilled right untop of the actuator so that wd40 runs down through the whole actuator that way and lubes it unstuck.
@@RWL2012 The sound is MMUUUUUUCCCHHHHH better. And the signal is a little bit stronger. But you have to make sure you have a 2008 Golf 5 or newer. In the older cars you have to change a gateway.
Great video thank you. Shame I removed the internal door card before learning accessing the lock is via the outer door skin! Never seen that before. Thanks again, much appreciated.
LMAO... I couldn't figure out why my Rabbit's rear door wasn't locking after removing the power window motor (Cables on the window regulator got messed up, did some damage to the gasket on the motor's output and I wanted it on hand for reference in case I was to get a replacement). This video made the issue obvious: I've removed the door's brain completely! Silly me, I hadn't even questioned why a window motor would need such a busy plug... Owning a VW has conditioned me to not bother myself questioning why the Germans design things the way they do.
My mk7 golf had a very similar issue however was a lot easier to fault find. Because the bad door was the drivers door, it means that the little module also controls things like the electric folding mirrors which should fold in when locking the car. However the drivers one didn’t and also the same issue as here where it wouldn’t lock and the window wouldn’t work. Easy mistake Vince not to worry
Excellent video. I’m great details. I have a similar issue with my golf mk5 where all the door la and windows work but my drivers door will not unlock or lock and the windows won’t work at the drivers door. So I am stuck with the door closed at the moment. Any ideas suggestions to get the door open? Oh and the previous owner for some reason blanked the door lock on the drivers door.
Thanks so much for this video, I succesfully diagnosed the right control unit of my mates golf 5 because of it! Didn´t have to bother with the outer shell either. Liked and subscribed!
I have same problem in my Jetta 2005 I change the look and still not working I order window motor I will fixit tomorrow I hope the problem will solve because every day I find the battery no electric
Hello , i have a issue wirh driver door , it lock and unlock with key but with thë remote not all the times ,the other doors are ok ,and windows all works. Can you help me?
