VW Polo 9n repairs. Episode 7, rear door lock module. 

If you found this video helpfull and it saved you spending a lot of money at a main dealer or garage then I would be really grateful if you could drop me a wee donation using the super thanks button and help me make more of these videos. Thank you all, Dave.

I worked through this with no car experience- and got it done thank you! People have asked for bolt sizes - here you go in order of undoing: Door handle t30 torx Door bolts - 10mm standard bolts Inside handle bolt - t20 torx Lock fixing bolts on side of door M8 Spline The bit I found fiddliest was getting the plastic washer back into the window - I couldn’t get the inner compression part in at all. I too avoided the drill part - the lock is fitted facing upwards - you can just prise the bolt off with a screwdriver- works fine.

You're a bloody hero. Rear right door had been deadlocked for a year and would have failed it's MOT today. 3 hours and some stress later I'm sorted. MY MAN

Really helpful video. Fixed lock, Thanks for no muisc, no annoying voice over. Love the cheers at 5:15! Could add info on screw tool sizes especially the hidden screw in the door

Completed thanks to your video, for anyone needing some dimensions for drilling the hole I hope this helps, 45mm down from the dead centre of the hole with the slot as shown at (4.50). I also found it easier to grind a taper on the two plastic dowels to put the window back in place, I used an 8mm bolt with a nut to exert equal pressure to tap the big dowel in using a centre punch in the middle of the bolt head, and exactly the same with a 5mm bolt for the smaller central dowel, whilst pulling the wire to one side, what a pig of a job, thank you VW.

Wow, thx for this awesome video!!! best tutorial around!

Watching your video removed any thought i had about replacing my self the lock, Bless you man!

Great video, helped a lot. I found that I didn't need to drill to get access to the screw. Once located, I prized the plate and it snapped off quite easily. Once off the door would open. The window dowel is frightening. I didn't dare hit harder so in the end I screwed a screw into it and pulled it out. Once the centre was out, the outer pushed through easy. Thanks again, without this vid I wouldn't have attempted the job.

VW should give you an award. Brilliant. Thank you 🚙🙂

I've watched a few of people fixing this, this fellow is the best, most clearest visuals, super instructions and very concise. I may have a go! Thanks to this video. Peace be unto you.

That is the best video for that common issue! Helps a lot if you want to save some money and do it yourself. Great job!

Thanks man! Now I have a well functioning door again thank to you!

great video. now i have to replace my locked backdoor vw polo 2005 9n because it works every other day. thank's for the video !!!

Thank you so much for this! Wouldn't have had a hope without your video - excellent! :)

Best video on doing the 9N Polo "dreaded rear door lock mechanism up the creek" by far - thank you!

Excellent funny and informative video with no annoying music. Yes, same happened with mine but caught it while its was in intermittent failure mode. This door lock failure is common across all VW's of this age. But the North American market VW's don't have deadlocks, so can be opened from the inside when they fail. VW don't like North American law suits, leaving the rest of the world potentially deadlocked within their cars.🔒😱🔒

Great vid. Just did this job myself at the weekend. The previous owner had already drilled out my lock so just had an unlockable door... I located a salvage lock from my local yard.. £6. To have made the job even easier, could have just removed the entire inner door panel and swapped them with locks still in place. When I was removing them from the salvage car I found the white plastic shroud the lock sits in is very very brittle, so avoids the risk of breaking it. Got away with it on putting it in my car but I broke the one in the scrap car.

Thanks so much for the video. I managed to change the rear left lock on my daughters car following this video. I would have had no clue on my own and garage would have charged a fortune.

Did the door lock on my Leon a couple of months ago, caught it before it was stuck shut. Good tip about drilling a hole and unscrewing. The other advice I've seen was to smash the lock apart.

Thanks for the video couldn't have done the job otherwise.!!

This just happened to me as well, rear left door. Fun times, your video will help a lot!

Brilliant solution thanks, worked on my 2003 Seat Ibiza Mk4 rear passenger door. So, thank you very much for putting it on RU-vid, would never have found that little screw, or dreamed of removing it to open the door that has been stuck shut for a year. It did take a few tries with a19mm hole saw to find the screw though!!! its a lot further back to the door edge than you think.

I have this exact problem with my polo, thank you !

Great video I too cheered at the right moment 😀 Amazingly fiddly , would have been stuffed without this .. thank you A LOT 👍👍

Thanks, brilliant video and saves loads in garage labour costs

MOT due in a month which it would have failed cause of this. Just spent the afternoon following your vid to fix it. Thank you! Was a great help!

Hey man, top video. Really helpful, I really wouldn't have had a clue how to fix this otherwise. Many thanks, have subscribed and will be back to fix more stuff on my wife's Polo no doubt. I'd also like to say that the presentation, camera angles etc. are spot on. No unnecessary chit-chat, no awful music, just a few helpful captions/warnings and get on with the job. Didn't have a spline drive to hand on a Sunday afternoon, so had to resort to the dreaded mole-grips. Worked a treat though, jobs a good 'un 👍

that "ooofff" at the end soo relatable xD great videos champ

Congratulations. Very Helpful.

brilliant saved me a fortune good vid

Good video super job, tanks

Thanks very much for this video, it helped me to repair mine. When reassembling, I pushed the plastic roll pins into the window before pushing the window down into the carrier, because I just couldn't get the pins back in place like you did.

A big thank you from France your video helped me a lot good job !!!!!!!!👍👍👍

thank you so much for this video, very helpful, just saved 300€ thanks to you!

Dankeschön. So ging es Prima. Super. Vielen Dank.

Fabby video. Helped me out brilliantly. Cheers

Super utile aceste filmulețe,multumim

thank you for the nice video, I managed to replace the lock with your guidance!

thank you so mush!! i have EXACTLY the same problem!!!!

Tolles Video 👍danke für die Hilfe

Thanks for your video it helps alot

Brilliant video. Very helpful. Only thing I didn't do was put the rubber grommet back for the window😂

Thank you guys!! :)

Thanks for making this very usefull video. The locking mechanism of my polo 9n3 passenger door has died and wont open. To make it really interesting the electric window on that side refuses to open 😮So far I managed to take off both panels but didnt get the door open. You showed which screw to use so im pretty confident ill be able to open it. Just gonna wait until my new lock is delivered because not being able to close the door would s*ck just about as much as not being able to open it. 👍

Il miglior video per riparare la serratura dello sportello posteriore

Un grand merci pour cette vidéo précise et parfaite. Elle m' a aidé à réparer les deux portes arrière de ma polo et réaliser une sacrée économie.

Great video

Super video!!! Thanks

@BTJustice Thanks very much for this, made my life soooo much easier swapping this out.

Awesome. We have a 9n polo. Same door problem. Driver rear. Will watch couple of times then attempt.

You helped me alot🎉 Thanks

Super, very helpfull. I fixed my door the same way🎉

Just finished both right and left rear doors , first door took 5 hrs and the second 1 1/2 hrs. The tricky parts for me , removal of the door card - expect to get brutal ! , and removing the window dowels, knowing now I would order new dowels before starting so I could drill out the centre dowel ( these are two expanding dowels ) , the rest was just fiddling

Just want to add my thanks here. Replaced the lock on my 9n3 on Saturday and it's all good now. £23 for the lock on eBay. Couple of issues I had where you had no problems - firstly the removal of the plastic tube wedges in the window lifter, this took quite a bit of persuasion but eventually they both went through (separately of course). Secondly releasing the door pull from the exterior handle - it was almost as if the plastic had bonded in some way. Eventually got this out using a small flat head screwdriver with a little damage to the plastic end. It went back together fine though. Cheers!

Thanks from France

I fixed my door alone !! Danke !

Good job

thank you very much!!! I have the same problem on my Polo! 🙂

Funktioniert super. Vielen Dank nach Glasgow 👌👍

Good job thanks

Great job

You beaut!! Exatcly what I'm on with now !!

Couple of observations/tips. Where Dave is wrenching off the main fabric door card I managed to get my lever under the edge of the metal inner door piece and bent it - so take care with that. The plugs where the main door card are fixed can be seen at 3.17 - as in the holes where the plastic fixers plug in. I found that some stayed on the door card and some stayed on the inner metal door piece - same happened in the video - you can see one that got left in the door frame at 3.17 near to the seat belt anchor. It is best to replace all of these plastic fixers, and it is easiest to remove them from the metal door piece once you have opened the door. You need some force and a flat item like a table knife to level them off. Second thing I found impossible was disconnecting the electric plug. I could not get my fingers round to the release point when the lock was in place. You don't need to. It can wait until you have unbolted the door unit. I'm still pinching myself that I managed to do this job - I have very limited experience in this sort of thing. Only successful because of the video

Ty vm it works now! I have to add a comment to 3:00. What you have to do here is to remove the two plastic clips. These clips holds the window. You can find the clips in the bottom of the door when you have knocked them out and when the metal panel isremoved. Dont worry about losing them when you knock on them. When everything is done just put them back in the hole when you are sliding the window back in place. Good luck. 😁👍 Btw. I thought that replacing right rear lock would fix the other doors as well but it seems that I have to replace the lock in each door.

Thank you so much for this video.

Thanks!!!! From Hungary.

Good vid thanks

I have the exact same problem on the drivers side rear door of a 2005 polo twist. It looks a fiddly job to fix this but thanks for the tutorial video which gives clear guidance. There do seem to be a lot of these reliability niggles with VWs from this era when they cheapened everything down to maximise profits. If only everything in life was as unreliable as a Volkswanken😁

Thanks a lot for the video. Fiddly job but I managed. Like others, my window pins (dowels?) did not come out easily at all. I had to squirt a small bit of WD40, and thread a 5mm bolt into the small inside pin. Even then it would not pull out with any reasonable amount of force (didn’t want to break the glass!) so I wiggled it and pulled the bolt gradually bit by bit and it eventually shifted. Once the centre one was out the outside one could be pushed out gently and carefully. I also reinstalled and centred the window dowels whilst I had the window taped up in the highest position and before I put everything back together. Then once the metal panel was back on I I removed the tape and slid it down into the plastic holder where it clicked into place no issue.

Vielen Dank. Genau die Anleitung, die ich brauchte. Es gibt wohl verschiedene Ersatz-Schlösser. Mein Ersatz hat keine Sicherung für den Schließbügel (Draht nach vorn). Der rutschte dann heraus. Habe ihn weggelassen.

Merci monsieur ! J’avais le même problème, grâce à votre vidéo j’ai pu réparer pour 36€ !

Dziękuję i pozdrawiam.

At least one door is locked -- An owner of similar Polo.

Thank you for this video. It’s really helpful. Could you also do key synchronization?

Planning to do this on the front door of my 2000 Golf SDi as the door no longer operates the cabin light. Thanks.

Thanks

just what i needed. i have a 9n3 and the left rear door is locked

Just got mine finished! I have drilled a cloverleaf of holes instead of one, HaHa! And three attempts to get the plastic spigot back into the window lifter! Top Tip, don't put all the screws back into the panel until the window spigot is refitted, if you just do the top two corners you can fish out the spigot when you push it through the glass.! Great video, saved loads of knuckle skin and swearing. Cheers!

Merci réparation ok good

Thanks heaps man! I was looking up and down youtube for a demonstration how to fix this, finally found it and can go to work! What part type did you order? Simply "rear right door lock"? *edit* never mind, you already answered it - door lock module. Noted and thanks again!

I have a polo 9n 2.0 but it has electric windows, the rear door was deadlocked for months but one day i punch it while trying to unlock it and opened lol

Can you show me how to fix my washer pipe at the rear it just leaks out the back when I try wash the back windshield thanks. Loved your cv joint video aswell really prepared me for what was to come

Any upload on opening up of the faulty actuator and cleaning / diagnose it?

Thanks for the vid man! Do you remember what size is the torx used around 6:13 to release the locking from its place?

I have got stuck at '6.12' on your video - what is the bit that you are using - is it some sort of spline bit, what size is it? I tried using a star shape bit (size 40) but it slipping and im worried im going to round off the bolt.

Very helpful video, thanks. I'm halfway through the job. Unfortunately, when trying to tap the plastic dowel out of the window, the glass shattered. I have the replacement and will attempt to reassemble.

Really helpful video thanks very much - central locking replaced and working... magic! however, I stupidly unscrewed the small Torkx bolt that is used to remove the rear part of the door handle... and a semi circular piece of metal and the screw fell into the inside of the door - so I took the door card/insides off and retrieved them... the trouble is, I cannot find anything about how that part of the door lock goes back together... I assume that I have to take off all of the door liner/door lock etc to access the area.... an ideas?

I have the exact same issue on my 52 plate Polo 9N rear left door (car has central locking). How do I know which lock to get as there seem to be several different variations for the door?

Since in my country Toyota is the major selling car, I and many used to think German cars are best, but after owning VW polo and seeing many complains of people from other brands like bmw and audi I realize the value of toyota and their reliability. Nothing comes close to Japanese cars!

Does anyone know if a Polo 9n3 passenger door will fit onto a Polo 9n? (3 door)

Hello! Are those front mudflaps stock? My 9n (post-facelift) does not have it, of course the mud was accumulating behind the fender for 10 years, so it started to rust there. It is quite annoying, I'll have to repair the paint, remove rust, etc. On your car I do not see rust there, although on most of the polos, golfs I see the sill rusting due to this.

Hello, thank you very much for this explanatory video. After following your advice, I installed a new lock and the problem is still the same. Door blocked 🥴 do you think there is a problem with the electrical wiring harness located in the door??

Can anyone tell me whether it is 6 or 8 pin connector please. Mine is 2007 44kw 😊

Great video. Unfortunately I am no closer to resolution. I have followed your instructions carefully after originally trying the many 'solutions' available on the internet. My son and myself created much amusment in a local supermarket carpark as we practically destroyed the offside side of my Polo, clicking. snapping and kicking. NOTHING! Finally gave in and proceeded to nearly destroy the door card but suceeded with that. Fiddled around trying to move various levers, etc. NOTHING! Drilled hole as instructed and loosened screw which has disappeared somewhere. I'm left with a hand-full of screws, levers and various other bits and pieces. STILL DEADLOCKED and immovable. To beat it all I can't for the life of me get that electrical connection off. I'm on the point of cutting that off now. Do you suggest a jack hammer? I have no intention in spending £300 for some 'technician' to fiddle around with. Any ideas? Thanks

mate this video is great!!!! mine locks/unlocks sometimes but majority of the time stays manually pushed into locked position, can I fix it the same way?

Hi great video...please do you have some dimensions in mm for reference of where to drill a hole in the door ?

Hi' I'm following this video to repair my car, but when you hit something in the hole of the window, what is that? Because Mines a bit different to yours and I have a ball bearing holding the window from the panel. Do you know how to get this off?

Is there a problem with my mom's Polo 9n? When she turns the key in the ignition to the point before when it starts it goes: Bung, Which is normal but it then goes: Beeeeep, Which i have not heard on other polo 9ns, And then after that after a minute or so it goes: beeeeep beeeeep beeeeep, With no warning lights, If you know what it is, plsss let me know.

Hey When I lock my polo it makes a weird noise to tell me it's locked. It's really loud and Sound like it's coming from the door where you have changed the lock for. I'm guessing the central locking motor is there? If I was to change the lock would that also fix the noise. Hopefully that makes sense Great vid btw, along with other polo vids you have they have helped me a lot

11:15, where does this hook onto or fit into? Been trying to do it for ages and it keeps falling out... many thanks
