Now who would think that your vid posted 10 years ago is legendary here we are in 2024 and boy did your vid help I have quite a rare 1998 B5 1.8t turbo sport had it nearly 20 years now still love it drives like a dream still not much has ever gone wrong with it until recently window regulator easy job but made a couple of schoolboy errors haha eg should have taken the module off when I had the regulator off but dohh I forgot so had to do the whole lot again respect to you your knowledge on VWs in fantastic 👍👍👍👍
I took a microswitch apart for a VW Beetle actuator, the spring inside and all the metal just fell to bits. :'( I bought another second hand actuator and it also had a duff microswitch. I might have a pop at fixing this one. Did you just use electronics cleaner like he did in the vid and is it all good now?
Thank you for time and commitment you have in contributing to the greater good. Tried the things you suggested above but was still operating intermittently. The solution in my case was to pry the motor retaining tabs apart (as there was carbon staining apparent through the translucent plastic end plate) blow out the deposit, gently clean up the tiny armature with a bit of fine emery paper, scrape the insulator with a fine blade, I only had brake cleaner available, so splashed a bit of that on, dried off with an airline and reassembled. Now it functions perfectly.
He knows what he's talking about. However, it is not necessary to remove all these parts to get that troublesome switch out. Just clip the wires and replace it without opening that delicate cover and separating all the mechanicals.
Your videos are great! Very informative, I've been wanting to do this repair for a long time on my MK4 Jetta but was a little wary, but watching you preform the repair has given me a better sense of what I need to take on the project. My only concern is that where the lock cylinder meets the module is broken as well as there is no resistance when I turn my key.
We have 2008 Tiguan, already changed the door lock module couple years ago, but here comes the problem again, that's how I came here. We've spent almost all our vacation in Italy searching for the VW services so we could lock our car because the lock broke at the beggining of the journey and the front door couldn't be locked automatically nor manually!!! And it is not the only lock problem that we've had. I think VW's have some s*itty door lock systems. Thanks for the video BMAC.
Yes and no. I bought my wife a cheap Honda Logo and its of so poor quality everywhere, that we're mentally prepared to "forgive" the flimsy design and always buy a new replacement, whereas the VW is expected to never fail AND be repairable without any doubt. Why? If spares (OEM, not Chinese knockoffs) cost about the same.
Thanks mate. I removed the lock with a microswitch for the Škoda Octavia A5. It's a different lock, but it's the same micro switch. It does not have to open a lock like in your video, because it's outside the lock. I did not have such an electric cleaner, but I cleaned the contacts with fine sandpaper. Now the micro switch works normally.
WOW, this was extremely helpful in getting my driver door fixed. The way you walked through and explained every single part step-by-step could not have been done any better, and thank you for using an HD camera to film this so we can see the small parts, especially when it came to re-seating the T-bit back in to the black clip. Definitely one of the best walkthroughs I've seen on here. My driver door doesn't recognize when it's open whatsoever and the old WD-40 trick didn't help at all, so my next step is taking it out and doing exactly this. Do you think it'd be best to re-solder all the contact points while it's open too, or is that not what causes the problem with the door not recognized as being open? My alarm has never gone off on me and and it locks and unlocks as well as arms the alarm using the key with no problems, but if I don't have to spend all that time and money on buying a solder gun for something that isn't the problem then would be a huge saver. Thanks again, keep up the great work!
BMAC VAGS You have produced an excellent in depth and clear tutorial on the subject . I only wish it had been around when I fixed my lock on a Touran. I bought a new lock at around £100.
I wish Id seen this 3 weeks ago, just bought a new doorlock barrel for $225 and the problem it seems is the micro switch.great video thanks for taking the time to put it up.
Thanks a million BMAC VAGS 100% i should have followed this DIY fix a year ago already but was just too lazy, now this was on a vw polo 2006 model. well i found the tiny 'T' shaped button on the micro switch broken into three pieces, but with a bit of Q-bond kit i managed to get it all together again. now my door is 100%
Planning on putting this to the test tomorrow. This video was very in-debth and i feel confident fixing this. Also glad i dont have to spend the $50 to replace it.
Great vid! I just bought a VW T5 multivan today got home and realised the drivers door opens with the key fob but doesn't lock with the key fob. Its not a big problem I just use the key to lock it but I will certainly have a bash at fixing it after watching this. Thanks for the vid
OMG, Thank you for making this video! I will be trying to do this with my Dub. I have had two dubs with this problem. It is too common! Thanks for taking the time to make the video. I will certainly try to buy the switch from you if I am in need of that switch.
Thank you, 1958, for the awesome video and very well detailed description on RENNLIST. I'm a visual guy, so I'd like to ask for a link to the video where you show how to remove the panel. You mentioned some wires get pulled, others you work around. Need to drill or grind rivets, then sheetmetal screws to keep things together. I'm confused. Mostly afraid to do it incorrectly and end up with a door with no panel. I know his is an old post but I'm hoping you have a link to a video for this... thanks, you rock. V.
Thanks for my micro switch which arrived yesterday. All fitted and working great!! I need to get central locking switch working now. When I operate the close switch in vehicle all doors lock but the door I’ve recently fitted switch to locks and then re opens straight away??
Finally got round to removing the lock mechanism, I just hope I can take it apart, clean it and get the thing back together, I'll be studying your video. Thanks.
Brilliant description on how to repair the fault. We have tried once before but never checked the micro-switch. thanks I am sure this is going to rectify the problem
Great video. I'm surprised how easy you made that seem, as long as someone is willing to out the time into it. I just bought a very ragged 1999 golf and it has a lot of projects needed. This might be one of them.
Hi mate, great video. I have a question, my b6 passat when unlocked doesn't allow me to open the door from the outside, I have to pull interior handle and then I can open it from the outside
hi mate ive got a 2012 audi a3 that has a locking problem it unlocks via the key but will not lock off the key i can manually lock it on drivers door but only drivers door locks and boot does not open unless you do it through the boot manually .i would be very grateful of any advice as you are the top man on vw and audi on utube thanks
Wow, thank you so much for the great effort you put in this video. I do not understand how you got 21 unlike! !! Great video... keep up the good work man. Thanks again
Hi BMAC VAGS, very instructive and clear video. Like some others who have commented my door lock has the relevant microswitch riveted to the frame. What's your advice on how to take this one off for inspection (and where necessary repair or replacement) and more important put it back on in a way that it will function again?
Brilliant video. I've got this module on both my own 3-door VW Golf (2003) and my mother's 3-door VW Polo (2007) - on both passenger doors. The passenger sides puddle light doesn't come on, central locking affected on passenger doors, and a diagnostic scan comes back with an issue pointing to door module. It's a great video, and so is your other one - about actually accessing the module. I might give it a try. Thanks so much - you're the best.
Hi, my mk4 golf, drivers door only intermittently unlocks (I have to tap the door a few times for it to open. Would this be the micro sim for unlocking the door sticking and if so where would I source one thanks.
I i ow this is old, but if you see this - thank you. I didn't need to fix the door sensor, but I've been trying ti figure out a way to install a cheap relay-based remote locking kit in the VWs, becsuse my lock cylinder is busted. Installing such a kit is a proper PITA on these VWs because at least on the Passat B5, the driver door key and lock cylinder doesn't actually actuate the door lock in any mechanical way; it only rotates that plastic cam, which push on those two microswitches to trigger the door lock actuator. And if you can't make it do that, you're kinda screwed because the door locks circuit on these cars actually operate over can-bus. The only circuit in the car that does. Thanks to your video, I now see how I can hook this up: drill a small hole, hook the remote kit relay outputs to the pads on those microswitches.
sweet dude I will give this a try. I noticed a small piece of white plastic fly off when you opened the parts, what was that? did you break something? You also mentioned a rubber seal that was broken or cracked. You didn't mention replacing it. I think what happens is that people forget to close their windows and water gets inside the door and allows dirt to get in there like your video. I think that's what happened to mine.
Thanks a lot for the video, helped a lot! (1999 Passat 1.8t) The problem I found with one of my modules was neither the switches nor the solder connections, but the little motor was having trouble. I tested it with a 9-volt battery and found it would operate intermittently and would work once I gave it a nudge. I sprayed it with some all-purpose lubricant (need to buy some of your electronics cleaner, probably) and it seems to work much better. The problem I had was that I'd hear the whir and maybe see the lock move a little, but not make it. Sometimes helped by alternating lock & unlock until it would engage. Next door to do is driver's-side rear, which has some of the symptoms you mention... central unit never recognized that it is opened and lock actuator doesn't work.
sjkellogg I have the same Passat 1999. Drivers door not lock from the inside. It locks and unlocks immediately and all other locks (except 1 back) are locked. Did you find a solution?
Thanks for this video, really useful. I've got a Mk1 Octavia and it wouldn't sense if the drivers door was open, so no alarm sounded if you left the lights on when you opened the drivers door with the ignition key removed. I had to replace the microswitch, got one from Maplins for a couple of pounds, and with a slight modification to fit it, all is working perfectly.
Hi thanks for your video my golf passenger door is locked and won’t open I’ve managed to remove the door card with it locked shut and can get at the levers but it won’t open press the key to open and it clicks twice but won’t open I’m thinking the actuator inside is broke or stuck I’m at a loss how to open it so I can replace the lock just wondering if u have and ideas hope u can help regards Rich
Hi, great video. I change that switch with a new one. Problem is door don't open from outside when it stays 1 day ou more, but when you open from inside it works well. Any solution!!??🤔🤔 Thanks to much
Hi BMAC. I've got a mk4 golf gti 2 door. Both locking modules are playing up. On Both sides the puddle light aren't working and to top it up the buzzer is gone. Really tempted to give it a go. I live in London, whitechapel area. Can come and give you a visit if you live local and have time to spare. Thanks mate!
Thanks, this is an excellent video. I recently had my door module replaced because the alarm would go off at random, the dome light didn't work, the indicator signal for headlights left on didn't work, and the doors would lock when they shouldn't. Everything is now working fine, except the alarm has still randomly going off. Is there possibly a reset or something for the alarm that should have been completed? It was an expensive repair, and I'm at a loss. Appreciate any suggestion (s).
Nice video. What would your think the issue is when the door won't lock or unlock (electrically). I have to use the 'mechanical' key lock on the drivers side and then have to reach across the seat to unlock the passenger side with the handle. My passenger side door stopped first and then months later the driver's side also stopped 'electrically' locking/unlocking. I was going to purchase an entire module, but after watching your video very much feel I could repair them instead. I thought it might be either a solenoid or motor (not knowing how it really functions). Would be very interested to find any suggestions for repairing my issue. Thanks!
Thanks. Great vid. Hope I can do same. My drivers door lock on crafter stopped locking the door. Central locking hasn't worked for months. No damp in overhead console. I did drop coffee on the top (cup holder] the other day ! Oops
down to the point! good job keeping the video flowing....I come across a lot of videos of people talking about their video when they need to get on with it already. job well done. as for the instruction, I have yet to attempt it, but it sounds like the issue I am having. worth the shot before dropping $180
That is exactly the problem with my 2006 Jetta 2.5...No Chime, no buzzer when I leave headlights on, no door open indicator in the instrument cluster/dash, no bottom red light, no courtesy lights when I open driver door...looks a lot easier to replace the entire unit for 22.50 on eBay instead of messing with it...I can finally say that I KNOW what the problem is. Thank you!
Again, congratulations on another fantastic video. You are really gifted in explaining how everything works. I am looking forward to look at my door locks. Thanks, JC
Thanks for this video, it was seriously helpful. Its worth noting that my Australian delivered Bora 4Motion V6 was slightly different than in the video. The spring catch that you showed is different but not likely to cause a problem. The big difference is that the microswitch is permanently mounted. The silver housing to keep it in doesn't exist and the 2 locator pins at the bottom are welded in, so not made to pull it out. I broke the welds and super glued it back in. It works for the moment but if it goes again I'll buy a replacement. What "went" on mine is that the welds had probably stretched and the 'button' was sitting above the part it is pushed in by. Hard to explain. Switch wasnt being switched. I'm not sure if its worth doing the other doors as they've all gone. Might just buy replacements as I cant see my "Fix" lasting too long.
I had the little plastic pin that holds the spring to the housing break off it appears, when I took the switch apart the contactor and spring were just floating around. I'm going to try just removing those parts and leaving the circuit open, which I think will just tell the computer the door is always closed. Don't have time to order a new microswitch and I'm not doing this twice! :D Thanks for great video to confirm what my problem was!
I have almost the same kind of problem. ....I should never have taken the switch apart. ...it made a klicking noice, so I guess it was OK. But when I took it apart the super tiny spring and another small t shaped part came loose. Can't figure out how to mount them back correctly. ..Only 2 loose parts inside the switch right?
Super video mate! This may be a silly question, but, can i swap the module from drivers side to passenger side? As the central locking does not work from the Drivers door, but works from the passenger door.
The Golf V has the same locking system ? I have this intermitent problem with the driver's door... It stoped working from remote and it works only if i use the key ... All other doors respond to the remote imput ! thank you, NICE VIDEO ! SUBSCRIBED !
I have a 2004 Skoda Fabia. When I turn the key in the door the windows in the front doors go down. (The rear door windows are manual) Could this fix resolve my issue? Thanks for a great vid. I'm glad I found you. I will subscribe.
Nice video!! Can a VW Golf MK3 that uses a pneumatic door lock mechansim be converted to a solenoid type universal actuator? The pneumatic pump is either expensive or out of supply already. Your input would be highly appreciated. Thanks.
Great video mate. Having some issues with my Seat leon at the moment. I've put the new microswitch, the one in the locking part. The new problem is that the central locking doesn't work on that door now and the locking mechanism seems to work perfectly...hmm anyway great video and I'm going back to work.
Cheers for the video mate! 01 Porsche 911 Turbo (996 Model) has the same mechanism and cleaning out the plunger fixed the window dropping and the interior light switching issue I had. Thanks sir!
The micro switch you dismantled and cleaned.....would that prevent the doors from locking? My '09 TDI locks wont light up the actual lock rocker switch on each door. At least 2 wont anyway...and they dont lock. I also dont get the confirmation horn "beep" when I clock it. Exterior lights do flash though. Love the videos! Excellent job!!
Hey Joey, I know that if the doors are 'seen' as open by the security system, it will not beep, just the lights will flash.. I found that my B5.5 wagon will do that if there is a door that isn't fully closed or the hatch or hood open.. once it's closed, it's sound the horn and flash again.. It sounds like your issue is either with the motors that drive the mechanism, or the micro-switch(es) that sense whether the module is in locked or unlocked status.. if you are able to open to the doors after locking them with the fob, my mechanical inclination says that it would either be the lock motor not turning (due to dirt or a lack of electricity) or a mechanical issue such as a component being broken.. If the door locks, but still doesn't sound the horn, I'd check to see if you have interior lights on, if so, it's the micro-switch cleaned in the video that would be the issue.. if the doors are sensed as closed, then it'd have to be one of the two micro-switches that sense if the module is in a locked or unlocked state.. (most likely the one that is activated when the module becomes "locked") Getting dirt or foreign objects in that sealed electrical area seems very unlikely though.. I'd bet money that it's mechanical.. all those plastic gears and parts are very easy to break if forced.. I found that out the hard way after playing that 'lock, unlock' game with someone in my 98 Volvo and they pulled the handle as the module was locking and broke it and I didn't know until someone opened my passenger door (that stopped locking electrically) and stole everything in my car.. damn.. lol Anyway, I hope that helps and solves your troubleshooting issue!
Thanks for the video. I have an issue with mine. Drivers door is in deadlock. Won't open from inside or outside. Carnt get the latch out the door as I carnt open it! Any ideas welcome👍
The actuator on my golf 2008 has a problem that the rear left door intermittently won’t unlock. When you press the button the lock makes a clunk - clunk lock/unlock sound. Sometimes it unlocks but not always. Any idea which micro switch to look at? At AUD 350 to replace the actuator I would rather just fix the micro switch. Hope the house renovation is going well. Thanks, great video
great tips and video. My 05 Passat has this problem. I am on my way to fixing it. I have repaired New Beetle switches by replacing them with one from Radio Shack, but this installation is much easier. Thanks much
great video man, the only question is that little pin you put in there to push the spring down. did you use the old one or got access to another one? Thank You
excelente. Gracias por el tutorial, he arreglado mi cerradura simplemente limpiando bien el microswitch y sobre todo metiendo svitol en la parte de la cerradura que va a presionar el microswitch
Hey again, thanks to your videos, not so long ago i repaired my vw bora driver side door switch, didn't light up the door light, the roof light, and i didn't knew that it had an alarm when you leave the lights on and pull the key out. :-)) Removed the door panel, removed the lock module and tried to fix it as the video showed. I couldn't split it in 2 to get the microswitch out, but i washed it with WD-40 how i could, and it worked exelent till a few weeks ago. now the lights go on when i open the door, the alarm beeps when i leave the lights, but when i want to close all the doors from inside with the remote, or the close button on the panel the driver side lock rod keeps popping out. is that the switch, or the weldings in the electrical side?
Hi any idea what the issue is on Mk5 golf's not unlocking/ locking? I assume the other microswitch may be the cause? Have you ever repaired this issue?
Hi, i have an other question. Did you have ever measured the resistance of the Microswitch inside of the lockmodule? E.g. from the switch which is sensing the locked/unlocked position? In my rear left doorlock i can only measure 60mega ohm or infinit. And for the SAFE/UNSAFE it is the same . Also the same resistances.
Hi. Great video. I have a 2006 passat and both drivers side doors won't open from the outside when I unlock them using the fob. I lower the windows and reach in to open them. Once opened they function fine until I lock, unlock them again and try opening from the outside again. Will this fix work for my passat? I hear the inner door card is a pig to remove. Any help appreciated. Thank you.
Sorry for the daft question...is this applicable to the mk5 golf? Got a ED30 and a 2007 Jetta with the same problem. Before I demolish the doors to get to it just making sure this is what I will find in there
Great video! Well done and instructional. BUT, had same problem on my 2001 Beetle driver side. Open door, no interior lights, alarm can go off, etc. The lock you have in video looks like an improved version, since my micro switch (with the wires) does NOT come off! It is hard riveted to the steel frame. I took the whole assembly apart like video shows, re-heated all solder joints on board, lubed, checked switches for good electrical functions...All ok. Re-assembled, and still had problem! Turns out that non removable switch fatigued and the plunger was not being pushed in enough to trip it! The fix is to force the body of the switch closer to the latch cam. I jammed a tiny screw under the switch and fixed it! Cheap cheap junk! Too much plastic! Grrrr. Thanks.
hello sir i really like your video and how you explane it my wife vw new beetle 2002 has a similar problem, the driver side door doesnt open for the outside any more..even with the key insert in the lock?..only from the inside i can open the door with the manuel handle do you think its a similar problem? thank gilles and tika
Good evening. Firstly congratulations on the video. I did the process on my Golf 2001 and now when I turn the alarm glasses are not closing. The rest was ok including the port light did not work and the headlights on audible alert back to work. If I trigger control I close the windows in the doors work. What can it be?
Many thanks for the informative video, it gives me some place to start. All was well, then my battery went flat and the central locking has refused to work since, except on the driver's door. Other doors will open, but only by using the switch near the window switches on the driver's door handle. Any further ideas would be helpful. Many thanks, Emma
Great job to fix it, but if you don't have your own garage when taking the door out your time out there in the street is limited, so you need a ready new part to fit it as soon as as you can before night time fall.
Many thanks for this video - I just took my rear lock mechanism to pieces and fixed it by reflowing the solder on the circuit board - apparently this (dry solder joints) is a common fault. The symptom was that the rear lock would unlock a few seconds after it was locked, which was very annoying!

Now it functions perfectly.
You’ve helped me out immensely, time and time again. Still have my stateside 2004 Jetta AWP / 5 speed/ 231,000 miles. Running like a dream. Thank you!
This, I'm so thankful for all the MK4 videos 🥰👍🏽🙏🏽🍺🍻
He knows what he's talking about. However, it is not necessary to remove all these parts to get that troublesome switch out. Just clip the wires and replace it without opening that delicate cover and separating all the mechanicals.
Yep just remove the retaining clip if that microswitch (door open/closed sensor) is the problem.

The fact this video has 1 Million views just talks volumes about this poor door lock design!
We have 2008 Tiguan, already changed the door lock module couple years

i fixed mine by taking it apart as far as i could and putting a bunch of WD-40 all over it. Hope this helps!

The best write-up on these lock modules that I've seen. Thanks, BMAC VAGS.
Great video, Ive had to do this job on my Mk4 Golf and it worked great for about 12 months and has just started playing up again.
This was very helpful and I manged to fix my central locking system with this tutorial!
Fantastic write-up, thank you very much!
I can only imagine how much Audi would charge to fix something this simple.
Replace whole locking mechanism...
Thanks for my micro switch which arrived yesterday. All fitted and working great!! I need to get central locking switch working now. When I operate the close switch in vehicle all doors lock but the door I’ve recently fitted switch to locks and then re opens straight away??

Great video. I'm surprised how easy you made that seem, as long as someone is willing to out the time into it. I just bought a very ragged 1999 golf and it has a lot of projects needed. This might be one of them.
Hi mate, great video. I have a question, my b6 passat when unlocked doesn't allow me to open the door from the outside, I have to pull interior handle and then I can open it from the outside
hi mate ive got a 2012 audi a3 that has a locking problem it unlocks via the key but will not lock off the key i can manually lock it on drivers door but only drivers door locks and boot does not open unless you do it through the boot manually .i would be very grateful of any advice as you are the top man on vw and audi on utube thanks
Wow, thank you so much for the great effort you put in this video. I do not understand how you got 21 unlike! !! Great video... keep up the good work man. Thanks again
Hi BMAC VAGS, very instructive and clear video. Like some others who have commented my door lock has the relevant microswitch riveted to the frame. What's your advice on how to take this one off for inspection (and where necessary repair or replacement) and more important put it back on in a way that it will function again?
Brilliant video. I've got this module on both my own 3-door VW Golf (2003) and my mother's 3-door VW Polo (2007) - on both passenger doors. The passenger sides puddle light doesn't come on, central locking affected on passenger doors, and a diagnostic scan comes back with an issue pointing to door module. It's a great video, and so is your other one - about actually accessing the module. I might give it a try. Thanks so much - you're the best.
Hi, my mk4 golf, drivers door only intermittently unlocks (I have to tap the door a few times for it to open. Would this be the micro sim for unlocking the door sticking and if so where would I source one thanks.
I i ow this is old, but if you see this - thank you. I didn't need to fix the door sensor, but I've been trying ti figure out a way to install a cheap relay-based remote locking kit in the VWs, becsuse my lock cylinder is busted. Installing such a kit is a proper PITA on these VWs because at least on the Passat B5, the driver door key and lock cylinder doesn't actually actuate the door lock in any mechanical way; it only rotates that plastic cam, which push on those two microswitches to trigger the door lock actuator. And if you can't make it do that, you're kinda screwed because the door locks circuit on these cars actually operate over can-bus. The only circuit in the car that does.
Thanks to your video, I now see how I can hook this up: drill a small hole, hook the remote kit relay outputs to the pads on those microswitches.
Thanks bro👍👍👍👌👌,, from india🇮🇳
sweet dude I will give this a try. I noticed a small piece of white plastic fly off when you opened the parts, what was that? did you break something? You also mentioned a rubber seal that was broken or cracked. You didn't mention replacing it. I think what happens is that people forget to close their windows and water gets inside the door and allows dirt to get in there like your video. I think that's what happened to mine.
Thanks a lot for the video, helped a lot! (1999 Passat 1.8t)
The problem I found with one of my modules was neither the switches nor the solder connections, but the little motor was having trouble. I tested it with a 9-volt battery and found it would operate intermittently and would work once I gave it a nudge. I sprayed it with some all-purpose lubricant (need to buy some of your electronics cleaner, probably) and it seems to work much better.
The problem I had was that I'd hear the whir and maybe see the lock move a little, but not make it. Sometimes helped by alternating lock & unlock until it would engage.
Next door to do is driver's-side rear, which has some of the symptoms you mention... central unit never recognized that it is opened and lock actuator doesn't work.
sjkellogg I have the same Passat 1999. Drivers door not lock from the inside. It locks and unlocks immediately and all other locks (except 1 back) are locked. Did you find a solution?

Thanks for this video, really useful. I've got a Mk1 Octavia and it wouldn't sense if the drivers door was open, so no alarm sounded if you left the lights on when you opened the drivers door with the ignition key removed. I had to replace the microswitch, got one from Maplins for a couple of pounds, and with a slight modification to fit it, all is working perfectly.
You are THE BEST repairman I ever saw!!! Greetings from Serbia!
Thank you brother

Hi thanks for your video my golf passenger door is locked and won’t open I’ve managed to remove the door card with it locked shut and can get at the levers but it won’t open press the key to open and it clicks twice but won’t open I’m thinking the actuator inside is broke or stuck I’m at a loss how to open it so I can replace the lock just wondering if u have and ideas hope u can help regards Rich
great info, what do you know about the wiring to the vac pump in the boot on mk2 golf and how to test it,what is live earth for it
I would have checked to see if the micro-switch had continuity after cleaning and assembly. A multimeter would test it.
Lol, just said the exact same
Hi, great video. I change that switch with a new one. Problem is door don't open from outside when it stays 1 day ou more, but when you open from inside it works well. Any solution!!??🤔🤔 Thanks to much
Hi BMAC. I've got a mk4 golf gti 2 door. Both locking modules are playing up. On Both sides the puddle light aren't working and to top it up the buzzer is gone. Really tempted to give it a go. I live in London, whitechapel area. Can come and give you a visit if you live local and have time to spare. Thanks mate!
Thanks, this is an excellent video. I recently had my door module replaced because the alarm would go off at random, the dome light didn't work, the indicator signal for headlights left on didn't work, and the doors would lock when they shouldn't. Everything is now working fine, except the alarm has still randomly going off. Is there possibly a reset or something for the alarm that should have been completed? It was an expensive repair, and I'm at a loss. Appreciate any suggestion (s).
Nice video. What would your think the issue is when the door won't lock or unlock (electrically). I have to use the 'mechanical' key lock on the drivers side and then have to reach across the seat to unlock the passenger side with the handle. My passenger side door stopped first and then months later the driver's side also stopped 'electrically' locking/unlocking. I was going to purchase an entire module, but after watching your video very much feel I could repair them instead. I thought it might be either a solenoid or motor (not knowing how it really functions). Would be very interested to find any suggestions for repairing my issue. Thanks!
Thanks. Great vid. Hope I can do same. My drivers door lock on crafter stopped locking the door. Central locking hasn't worked for months. No damp in overhead console.
I did drop coffee on the top (cup holder] the other day ! Oops
down to the point! good job keeping the video flowing....I come across a lot of videos of people talking about their video when they need to get on with it already. job well done. as for the instruction, I have yet to attempt it, but it sounds like the issue I am having. worth the shot before dropping $180
+Jordan Gray I'm Glad you liked the video thanks for the support
That is exactly the problem with my 2006 Jetta 2.5...No Chime, no buzzer when I leave headlights on, no door open indicator in the instrument cluster/dash, no bottom red light, no courtesy lights when I open driver door...looks a lot easier to replace the entire unit for 22.50 on eBay instead of messing with it...I can finally say that I KNOW what the problem is. Thank you!
Thanks for the video. It helped me a lot to disassemble and reassemble the lock module.
Again, congratulations on another fantastic video. You are really gifted in explaining how everything works. I am looking forward to look at my door locks. Thanks, JC
Thanks for this video, it was seriously helpful.
Its worth noting that my Australian delivered Bora 4Motion V6 was slightly different than in the video.
The spring catch that you showed is different but not likely to cause a problem. The big difference is that the microswitch is permanently mounted. The silver housing to keep it in doesn't exist and the 2 locator pins at the bottom are welded in, so not made to pull it out. I broke the welds and super glued it back in. It works for the moment but if it goes again I'll buy a replacement. What "went" on mine is that the welds had probably stretched and the 'button' was sitting above the part it is pushed in by. Hard to explain. Switch wasnt being switched.
I'm not sure if its worth doing the other doors as they've all gone. Might just buy replacements as I cant see my "Fix" lasting too long.
Superb guide. Need to do just this to my Polo drivers door. Its just started not letting me open the door from the inside.
Good Luck
I had the little plastic pin that holds the spring to the housing break off it appears, when I took the switch apart the contactor and spring were just floating around. I'm going to try just removing those parts and leaving the circuit open, which I think will just tell the computer the door is always closed. Don't have time to order a new microswitch and I'm not doing this twice! :D Thanks for great video to confirm what my problem was!
I have almost the same kind of problem. ....I should never have taken the switch apart. ...it made a klicking noice, so I guess it was OK. But when I took it apart the super tiny spring and another small t shaped part came loose. Can't figure out how to mount them back correctly. ..Only 2 loose parts inside the switch right?
Does the drivers door lock module control the auto lock @25km p/h feature ? Thanks in advance.. excellent desc vid.
Your CCM controls the autolock setting, but the door lock module controls the function
Super video mate! This may be a silly question, but, can i swap the module from drivers side to passenger side? As the central locking does not work from the Drivers door, but works from the passenger door.
The Golf V has the same locking system ? I have this intermitent problem with the driver's door... It stoped working from remote and it works only if i use the key ... All other doors respond to the remote imput ! thank you, NICE VIDEO ! SUBSCRIBED !
I have a 2004 Skoda Fabia. When I turn the key in the door the windows in the front doors go down. (The rear door windows are manual) Could this fix resolve my issue? Thanks for a great vid. I'm glad I found you. I will subscribe.
Sounds like the lock micro switch is faulty/dirty. Give it a clean and see what happens
Will do. Thanks! :-)
Thankyou..greatly appreciated
Nice video!! Can a VW Golf MK3 that uses a pneumatic door lock mechansim be converted to a solenoid type universal actuator? The pneumatic pump is either expensive or out of supply already. Your input would be highly appreciated. Thanks.
Thank You for your excellent video!
Now I confident to open and work on my Polo 9n locks.
All the best! BMac rules!
Great video mate. Having some issues with my Seat leon at the moment. I've put the new microswitch, the one in the locking part. The new problem is that the central locking doesn't work on that door now and the locking mechanism seems to work perfectly...hmm anyway great video and I'm going back to work.
Cheers for the video mate! 01 Porsche 911 Turbo (996 Model) has the same mechanism and cleaning out the plunger fixed the window dropping and the interior light switching issue I had. Thanks sir!
Gotta apply this fix tomorrow. Thanks for the how to guide bmac!
Hi, nice tutorial!!! Only one question: What is the car model of this door lock??? Is this lock from a Jetta MK6 or similar???
The micro switch you dismantled and cleaned.....would that prevent the doors from locking? My '09 TDI locks wont light up the actual lock rocker switch on each door. At least 2 wont anyway...and they dont lock. I also dont get the confirmation horn "beep" when I clock it. Exterior lights do flash though. Love the videos! Excellent job!!
Hey Joey, I know that if the doors are 'seen' as open by the security system, it will not beep, just the lights will flash.. I found that my B5.5 wagon will do that if there is a door that isn't fully closed or the hatch or hood open.. once it's closed, it's sound the horn and flash again..
It sounds like your issue is either with the motors that drive the mechanism, or the micro-switch(es) that sense whether the module is in locked or unlocked status.. if you are able to open to the doors after locking them with the fob, my mechanical inclination says that it would either be the lock motor not turning (due to dirt or a lack of electricity) or a mechanical issue such as a component being broken..
If the door locks, but still doesn't sound the horn, I'd check to see if you have interior lights on, if so, it's the micro-switch cleaned in the video that would be the issue.. if the doors are sensed as closed, then it'd have to be one of the two micro-switches that sense if the module is in a locked or unlocked state.. (most likely the one that is activated when the module becomes "locked")
Getting dirt or foreign objects in that sealed electrical area seems very unlikely though.. I'd bet money that it's mechanical.. all those plastic gears and parts are very easy to break if forced.. I found that out the hard way after playing that 'lock, unlock' game with someone in my 98 Volvo and they pulled the handle as the module was locking and broke it and I didn't know until someone opened my passenger door (that stopped locking electrically) and stole everything in my car.. damn.. lol
Anyway, I hope that helps and solves your troubleshooting issue!
my99ferrari I appreciate the quick reply. I will probably take one out and just examine it like you do in the video. Thanks again for the guidance!
WTF with the music opening? "Ahhh" 😂😂😂 Love it
Thanks for the video. I have an issue with mine. Drivers door is in deadlock. Won't open from inside or outside. Carnt get the latch out the door as I carnt open it! Any ideas welcome👍
The actuator on my golf 2008 has a problem that the rear left door intermittently won’t unlock. When you press the button the lock makes a clunk - clunk lock/unlock sound. Sometimes it unlocks but not always. Any idea which micro switch to look at? At AUD 350 to replace the actuator I would rather just fix the micro switch. Hope the house renovation is going well. Thanks, great video
Great video 👍very well done and very much needed. Thank you 🙏
Audi TT Mk2 suffer from this too. Brother replace passenger side a year ago, come MOT time, it failed again 😤
great tips and video. My 05 Passat has this problem. I am on my way to fixing it. I have repaired New Beetle switches by replacing them with one from Radio Shack, but this installation is much easier. Thanks much
Excellent video my friend, its the same procedure for a MkV GLI 2006 ? , where can i buy the micro chip in USA in case its broken ?
great video man, the only question is that little pin you put in there to push the spring down. did you use the old one or got access to another one? Thank You
excelente. Gracias por el tutorial, he arreglado mi cerradura simplemente limpiando bien el microswitch y sobre todo metiendo svitol en la parte de la cerradura que va a presionar el microswitch
The video was very interesting.Also I have a 2005 VW Tourrage and some time I have to bang the door for the doors to open any advise
Hey again, thanks to your videos, not so long ago i repaired my vw bora driver side door switch, didn't light up the door light, the roof light, and i didn't knew that it had an alarm when you leave the lights on and pull the key out. :-)) Removed the door panel, removed the lock module and tried to fix it as the video showed. I couldn't split it in 2 to get the microswitch out, but i washed it with WD-40 how i could, and it worked exelent till a few weeks ago. now the lights go on when i open the door, the alarm beeps when i leave the lights, but when i want to close all the doors from inside with the remote, or the close button on the panel the driver side lock rod keeps popping out. is that the switch, or the weldings in the electrical side?
Great tute. Thanks. Have you worked on Mercedes W163 (mine is 2001 ML320) door central locking ? My rears have failed.
Hi any idea what the issue is on Mk5 golf's not unlocking/ locking? I assume the other microswitch may be the cause? Have you ever repaired this issue?
Thanks for taking the time to make this. I'm going to be doing this to three.
Hi, i have an other question. Did you have ever measured the resistance
of the Microswitch inside of the lockmodule? E.g. from the switch which
is sensing the locked/unlocked position?
In my rear left doorlock i can only measure 60mega ohm or infinit. And for the SAFE/UNSAFE it is the same . Also the same resistances.
Excellent, with much thanks. Revealed my front doors micros are out. No doom light or warning on dash that doors are open not working.
Thanks nice video. Can you please help to show how we can unfit the back door to take the electric lock out?
Hi. Great video. I have a 2006 passat and both drivers side doors won't open from the outside when I unlock them using the fob. I lower the windows and reach in to open them. Once opened they function fine until I lock, unlock them again and try opening from the outside again. Will this fix work for my passat? I hear the inner door card is a pig to remove. Any help appreciated. Thank you.
Figers crossed this should work for your car. you will have to check all of the sensors and solder points as well.
Sorry for the daft question...is this applicable to the mk5 golf? Got a ED30 and a 2007 Jetta with the same problem. Before I demolish the doors to get to it just making sure this is what I will find in there
Is that a MK5 or MK4?
Excellent video! Lot's of patience and detail your efforts were definitely appreciated.
Thank you for watching
Great video! Well done and instructional. BUT, had same problem on my 2001 Beetle driver side. Open door, no interior lights, alarm can go off, etc. The lock you have in video looks like an improved version, since my micro switch (with the wires) does NOT come off! It is hard riveted to the steel frame. I took the whole assembly apart like video shows, re-heated all solder joints on board, lubed, checked switches for good electrical functions...All ok. Re-assembled, and still had problem! Turns out that non removable switch fatigued and the plunger was not being pushed in enough to trip it! The fix is to force the body of the switch closer to the latch cam. I jammed a tiny screw under the switch and fixed it! Cheap cheap junk! Too much plastic! Grrrr. Thanks.
Ingenious, love to hear testimonials like these. Excellent work!!
you are a proper legend. watched all your vids thanks for sharing your knowledge ☺
hello sir
i really like your video and how you explane it
my wife vw new beetle 2002 has a similar problem,
the driver side door doesnt open for the outside any more..even with the key insert in the lock?..only from the inside i can open the door with the manuel handle
do you think its a similar problem?
thank gilles and tika
Good vid I soaked my module overnight in WD40 which helped for 6/7 months then bought new ebay replacement for £25
Good evening. Firstly congratulations on the video. I did the process on my Golf 2001 and now when I turn the alarm glasses are not closing. The rest was ok including the port light did not work and the headlights on audible alert back to work. If I trigger control I close the windows in the doors work. What can it be?
Many thanks for the informative video, it gives me some place to start. All was well, then my battery went flat and the central locking has refused to work since, except on the driver's door. Other doors will open, but only by using the switch near the window switches on the driver's door handle. Any further ideas would be helpful. Many thanks, Emma
The central locking working on one door only may need to be put on the computer.
Your Videos are always very informative . Great Job.
Good video,best to test for power,signal and ground before you take the actuator out,check wiring diagram .
Great job to fix it, but if you don't have your own garage when taking the door out your time out there in the street is limited, so you need a ready new part to fit it as soon as as you can before night time fall.
Thanks for the reply and advice on c.c.m and door lock module.
You are welcome
Excellent video, thanks for taking the time to make it.....
Many thanks for this video - I just took my rear lock mechanism to pieces and fixed it by reflowing the solder on the circuit board - apparently this (dry solder joints) is a common fault. The symptom was that the rear lock would unlock a few seconds after it was locked, which was very annoying!
very clear video, thnx a lot ,you fixed my door alarm problem !
