Audi B8 A4 Door Lock Repair

[@sootpig]

Drivers door has stared doing exactly the same thing! If you need anything explaining/covering in more detail let me know and i'll make a follow up video for the drivers side!

[@viperboych]

excellent video, my drivers door has just done the same, video of drivers side would be appreciated.

[@bvcxzgt5451]

Brilliantly done. Thanks.

[@peterparker8806]

My passenger rear door just started having these exact symptoms today. Hoping to tackle this on my own now thanks to your detailed walkthrough

[@Mopo151]

hi, nice video, i have this problem too, but i cant open right front door even from inside, once in a while it works but most of the time i cant open it at all, is it the same problem as there? will changing the actuaor fix it?

[@FredKhuram]

Man this helped so much. I wish your video also covered how to separate the two sections which actually gave me a heard time but nonetheless excellent video. I was about to buy a new actuator and then saw your video. Thank you

[@ds8448]

The best video I have found on this particular matter! Thanks for sharing.

[@sootpig]

Thank you :) i hope it was helpful!

[@ds8448]

Yep, fixed it. Exactly the same issue - dirty motor commutator.

[@gideonsison9221]

The video did not show how you broke the mechanical side to the electronic side! There are three hidden screw on the electronic side. Putting it back is tricky as well.

[@GregKublikowski]

Thank you for your video and instructions , had same problem , did exactly as per video including cleaning small motors. Worked perfect.

[@Juninholondon]

Thanks a lot for the priceless info, I own a repair shop here in Brazil and the tips you gave solved my problem, thanks and keep up the good work!

[@f1kwa399]

Thank you for doing this, just used your guide to refurbish my Audi A3 8P rear door, much better than buying inferior replacement, whilst not the same lock as yours, it’s very similar👍

[@andreiconstantinapopei5428]

If you still have problems after this very good fix, you can find the motors on AliExpress/eBay, just search 12v auto lock DC motor, I have a similar issue and will order the motors first just to be safe when I fix the lock.

[@ryanh3285]

Hi I'm looking at ordering the motor's did they take a long time to arrive?they all say from China.

[@saschapeter5882]

Thanks a lot, was very helpful. Instead of disassemble the motor, I was using an electronic cleaning spray 4-5 times. The white cover of the motor was deep dark before I was using the spray and afterwards it was light. I have also used light air pressure to get it faster dry inside. I was also waiting an hour to be more save, that it has been dry. Sure your way might get out more, but it is now working like a charm. So I hope it will last a while. Disassembling the ‘mechanicals’ from the ‘electronics’ has been the toughest part, but the result was worth it.

[@hrguilhg]

Your are the best. Thanks so much. I'm just finishing to repair 2 doors of my A4 Audi.

[@keithg4103]

Thank you for posting this! Three of my four doors were doing the exact same thing. To have all the latches replaces would be a fortune. Was able to fix them all in a weekend for free. 😊👍

[@georgeshaw6207]

Brill video. This guy I guess is an electrical engineer. fixed my actuator but just sprayed motors with WD40 and worked ok. Splitting mechanical and electrical parts was a bit of a nightmare though due to locating springs etc. Ended up using some dental floss to pull one side of spring into locator when closing. Worth considering just changing unit for about £40 off e bay but I guess you’ll make your own mind up if you end up with a box of bits. Thanks for the video !!!!

[@VoPo20]

Thanks, just solved my issue using your video after I used following link for video on how to get to the door lock actuator: kzbin.info/www/bejne/iXfHgJlog5aLiMU As I had opened the actuator, decided to clean both motors, only a bit of extra work.

[@BrainXTV]

Great Video and great yob. Have the same Problem and same work to do on an Audi A8 driver side. Regards from Germany

[@john37694452]

Heck yea I fixed mine thanks to you. Audi quoted 550 USD for just the actuator. I fixed it for free.

[@ak-zq3hp]

You can clean the motors just by using wd 40 and compressed air.

[@biobrainshock]

Absolutely amazing video and helped me find and fix the issue. Thank you. Took motor out, cleaned the commutator, put all back together and voila - it works! Car is Audi A5 3.0 quattro 2 door year 2008. Thank you again.

[@sootpig]

Happy it helped :)

[@paruscrisstatus2867]

Saved me a small fortune. Brilliant upload. Thank you.

[@gneagu86]

Thank you for this great video that actually gets to the very bottom of the issue! It would be great next time to include the steps that show how to take it apart and put everything back although much of it is common sense. And always fix it in the early stages, I've ignored it and I've ended up with the door not opening from either inside or outside. Painful!

[@mattjohnson4280]

Thank you!! I just performed this repair on my 2010 S4 rear left door latch. Not exactly the same symptoms... mine wouldn’t lock at all, but the fix you provided worked perfectly! Saved me 200 USD. Really appreciate you posting this!

[@jhappy82]

Thank you very much man, your video was so helpful, I just solved the same problem in my A6. Thanks a lot.

[@dalegreen9135]

Excellent just goes to show you don't have to throw away and buy new every time 👍

[@gavinanderson3319]

Excellent video, many thanks. I had the same symptoms on my mk2 TT passenger door - the lock is identical & your video helped me get it sorted today . Many thanks :)

[@corvetteshorts4670]

Great video. my issue was the microswitch!!!

[@pkuukas]

Thanks mate! Got my driver's door fixed thanks to this. Contact cleaner spray worked a treat for the motors, did not feel like taking them apart.

[@jpwilliams5264]

Great video! I would assume that due to the limited travel of the motor is the cause of the build up.

[@sootpig]

The motor will actually complete numerous complete revolutions. However the fixed gearing means the motor will always return to, and start from, the same position every operation. This is also the moment of peak current draw so that part of the commutator is going to get hammered compared to the rest of the motor

[@shadowhadz6781]

Just started to have the exact same problem. Left side drivers door. Car is LHD. I am going to do what you showed me on the video! Would rather fix the problem than pay 175 euros for a new one from an Audi dealer or order the part from Autodoc app and pay 83 euros. You don't know if the cheaper version is from China and not as good a quality. Hope I can fix mine like you have. Thanks for this as helps alot.

[@simonsaysfpv]

There is not so many of us left😂 On the first place🥳 People which want to rebuild thanks and don't buy new one On the second hand people would share with the knowledge and experience which is useful🤠 Heads down for that what you doing please continue to do so and I will try to follow you. Best Regards F****** find me some useful movie

[@lanettedutra2253]

This video is awesome. I did the same repair on my 2009 Audi A3 rear passenger actuator and it worked flawlessly! Thank you very much, saved me $$$

[@peterpowers4851]

Thank you so much for making this video. This was very helpful.

[@ryanh3285]

Same problem on my 2008 a5 has been doing this on and off on passenger side for ages and now the driver's door is doing it the colder weather seems to make it worse.Great video thanks for posting.

[@waynep4256]

Thank you so much for this video, helped me fix my wifes seat leon locking issue😊

[@ytmozak2438]

I need some help. My old actuator was locking the door only with the key and I replaced it with a new one, but still central locking is not working and I couldn't lock the car with the key, so I put back the old actuator, but now I can't lock it even with the key. Do I need to do some coding after the new actuator replacement? The garages are opening on Tuesday so I'm looking for help now. My car is Audi A5 B8.

[@-robster-robster-]

Great to get a disection of a common fault that seems is built in to design .... it amazes me the Heath Robinson approach to many plastic mechanical parts in a chain and electrical components on the edge of purpose the vag group engineer into thier cars ! anyway you have saved me time hoping to come to the same conclusion and/or ££££ in parts muchos grassyarse!

[@edayatunmnor6653]

excellent video.. help me a lot.. build such confident to fix it myself.. thanx lot bro!

[@simonherman7346]

Audi TTS MK2 8J 2008 Thank you buddy!! I found that the larger left hand motor had a broken connector. I prised out the motor and one connector stayed on its circuitry and the other stuck to the motor. I took the connector out of the motor and soldered it back to the circuitry, it slots into its plastic slits just like the other side does. Then solder its wire arm to the circuitry. Once the connectors are soldered to circuitry and straight, the motor should fit back onto it's connectors. Be careful not to bend or force as they should align up and click into place. I hope this helps as this did the trick for me. Thanks to the video from sootpig!! You gave me the confidence to delve deeper!! Thank you so much!!

[@RichMantaray]

so they used a cheap moto lol but made the door lock really well LOL

[@paulatbirstall]

Excellent, you just saved me some money, problem fixed at no cost. Many thanks.

[@buddhudd1054]

I fucked up! Now when I lock driver's door it unlocks and vice versa ((((((

[@c.y.p3242]

Thanx man!!! I finally managed to fix my door lock on Audi A6 C6 Allroad 2007. Everything was exactly, like in this video. Works perfectly now. Great thanx from Czech Republic!! You saved me a lot of money. Other locks are coming soon. Sometimes happen also the same thing.

[@Lophkim]

excellent video, minor comment: first set of washers on first motor should be installed other way around (small one first).

[@robinharris1085]

I have the same intermitant lock fault on a A5 ¡ just hold open button On ,Window opens ,operate internal door handle .bing open door

[@charcoaldesign]

About to separate the electrical from the mechanical component - does not look easy! Thank you for the extremely detailed video. My lock is doing exactly what you've outlined in the first part of the vid so I'm hoping for success. Here goes… … Success. Thanks again!

[@sootpig]

Happy to have helped :)

[@jimmy-np6jy]

hello,how do I contact you privately?I have some question about the door lock motor.

[@desig1234]

Awesome video thank you , 3 of my doors have the same issue , both front and passenger rear , will try this hopefully sorts the issue. Is it a different process for the drivers door ?

[@Jora1987]

Thanks man, great video ! Just fixed both rear actuators on my A4 B8, now they are working fine, same problem with electromotors. Best regards

[@vampirtransilvania]

i see video it opens, but how does it close? i have not idea if after opening i put all good, it opens moving but cant see closing..

[@troublebrewing99]

Tried it on A5 door lock, mechanism is attached to electronics after removing 4 screws not going to seperate them.

[@ivancory7742]

Thank you for sharing... Fixed mine at the 2nd try. Your video was very helpfull. Enjoy.

[@davidthomas7032]

I take it this is why my door will open sometime and not other times it’s just what contact it’s getting?

I have a same lock and same problem in my 2010 Seat Altea XL. Thanks for help I fix it today👍

[@samstewart5956]

Thank you this is great! Fixed mine, always happy when it doesnt cost anything and learnt a few things too

[@simonconnell220]

Great video ..... Very helpful - used for the drivers and the passenger door.

[@andyverdin9418]

does anyone know if this will work on my 2009 audi a4?

[@franknutt1876]

Great video. My A4 has the same problem on the drivers door. I was going to take a look at it. This vid is such a help, thank you. I’ll let you know how it goes.

[@samielgo1]

Is it worth it just to get new once not from audi and just install them or this. Pressed for time and 3 of them need replacement!

[@rossn5186]

Aliexpress has the complete locking mechanism for around US$30.00, just make sure you order correct version based on your cars make/model/year.

[@SafeDriver18]

Thanks a lot man. Instead of cleaning motors I bought em cheap on eBay for $5 a piece from China and it works perfect. Finally can unlock my car with remote control. Just have to be careful with removing those arms. And I didn’t unscrew the lock from outside, I was able with both my hands to guide it inside that opening.

[@roxanneesp]

Hi there! Do you happen to still have the part you ordered? I broke mine while trying to take apart. Help please.

[@brianpage1462]

Hi do you have a video of where all the gearing gos thank you

[@eikkaheikkinen]

just finished doing this and yes.. i had the exact same problem. cleaned the motor and now it works just fine. thank you!!!!!!

[@sootpig]

Happy to help!

[@sulimangesur2138]

Worked for me Thanks!!! Good video!

Thanks for the video, i tried this but no luck for me, Quick question watts the yellow switch for? the one you can move sign a flat screw driver?. I think that my problem is with the handle latch. Because electrically and mechanically i can see it is working. If i close the lock and unlock the car with the fob I am able to open the door when i move the inside and outside mechanisms. I looked inside my car and i can see a bit of rust in the outside cable .

[@rossn5186]

It's a child lock, when turned the door will not be able to be opened from inside (via door handle)

[@GravyChap]

Thank you so much. After ordering a lock for my A3 (which turned out not to match, I have 8 pin, whereas 9 pin seems to be specced for my car). Anyway, this video, with extraordinary detail and great video work encouraged me to take the thing apart. I treated both motors in the lock. Rather tricky getting things back together, especially as the yellow pieces separated as did the spring in between. But thanks to your detailed videography I could just about see where things were supposed to go. tested fine, and now back in the car working well. My driver's door is the same, so might give that a go if I can convince myself that it wasn't a fluke getting it back together undamaged. I checked this morning with Audi, these locks are £182 each!

[@sootpig]

I'm glad you fixed it :) i keep putting off doing the drivers door but once the weather's nice i need to do mine too. Seems like a very common problem, and not hard to fix!

[@maksym3d]

Thanks man! Done the same to the back door of 2010 S4. So far so good. The washers on my motor seemed to be in a different order though, with the smallest closest to the windings.

[@wilkk7867]

7:40 - exactly! This is very important, ensure there is no graphite stucked between commutator contacts - it will cause a short. I had this exact problem (and missed it the first time I cleaned the commutator): although motor still worked, current increased to about 7amps peak (from, I think, 1amp nominal) and the door module started throwing various errors. In this case you can often hear a buzzing sound, because the driver (door module) is turning the motor on, then off (due to too high current) and then back on... and off... and on again... about 13 times in a row, in something like 200ms - so you get very short buzzing sound of about 60Hz.

[@ianrichardson4423]

Thanks, fantastically helpful video. Exact process fixed mine yesterday. Wouldn't have even thought of stripping the motor without your guidance. (Tip: dont activate the locking mechanism with the motors exposed, without the limit switches to stop them they chuck all the gears and the little spring out! All back together now though.

[@VISTATREKKER]

Thank you for this video. Just managed to apply your instructions to a 2013 A4 rear right door. Sure enough the motor was black with carbon. One tip though is that it’s possible to remove the motor without actually completely separating the black metal section from the plastic gear housing. If you remove all Philips and T8 screws you can see, and one that lies between the metal and the gear housing the various components can be loosely opened up and are flexible enough to pop the motor out without disconnecting gears from levers.

[@Rumdidam]

Couldn't open one door from inside, read manual, watched your vid, read Audi manual. Walked to my car and pushed the "close" button on my key 2 Times in row. Voilá it works again. I think it won't last long :D.

[@Drtorky]

Nice one mate! Are both motors the same? Already replaced 2 door locks on my A6 few years ago...... Still have the old "Broken" ones. Maybe I could use the working motors if another lock dies. 😂😂

Spot on advice mate. I had three doors that wouldn’t unlock with the remote. Just took all three apart and cleaned the motors out. They’re all working perfectly now. Thanks.

[@paulboakes6532]

Thank you for your informed video and has been a great help and have repaired the actual actuator and works great. However when I split the actuator away from the locking mechanism there was quite a bit of resistance parting the two modules. Finally was able to part but the spring on your yellow actuator arm sprung off and the top portion of the yellow actuator arm remained with the locking mechanism? The problem I have is that I cannot workout how the spring locates between the two portions of the actuator arm. Have you any still images of how this spring is relocated correctly holding the two parts of the yellow actuator arm ready to attach the actuator module to the locking mechanism. many thanks, Regards, Paul

[@MathiasMuller33]

Many thanks from France for the video !! will help me rebuild my A5 passenger door.

[@ryanh3285]

If anyone does this test it all with you're door card off. If pulling the exterior door handle when the door is locked resets the fault then you need to replace the exterior bowden cable as it isn't returning the actuator arm back to where it should be .It is likely to be the main cause of it failing . It's very easy to replace and reasonably cheap.

[@IndustrialRobots]

Great Video, have two doors that I have been putting off fixing for some time. anyone interested in getting the motors then search on Amazon for "AUDI Door Lock Actuator Motor" I have ordered 2 sets of motors :-)

[@DanShed79]

Excellent video. Worked perfectly on my passenger rear door mech. Thanks

[@Ricky3661]

Great video, lock is exactly the same on a VW Passat B6 with exactly the same problem.

[@CoenraadZ]

Thank you sootpig! Mine was doing the exact same on the driver side - sorted with the aid of this video which proved absolutely invaluable! Only issue on mine was that between the white and yellow clips, the yellow one separated from the spring rather than the lever it is attached to (causing the spring to come out). Trick was to put the spring back and wind it once using the yellow clip before before snapping it back on again. The other thing I found that made it easier was to remove the lock cylinder first. Just pop of the plastic cover (above the latch's top bolt) and then turn out the torx bolt (note it does not come out all the way). Then slide out the entire barrel. That way you can just attach the latch and slide the barrel back in afterwards instead of trying to line it up with each other inside the door.

[@Jfjs58-g]

They could have installed brushless motors right from the factory but if it doesn’t break later no extra cash for them.

[@carlwoollaston2068]

Followed your lead on a problem on my passenger door where neither the interior or exterior latch would release the door. Cleaned both motors, now working perfectly. Bit fiddly getting the electric portion back on the mechanical lock but with a bit of care it went back together ok. Thanks for the video.
