If you found this video use full 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.
Thx, PS : In other videos, people dont change it but just open it and clean it with electrical Contact spray. Please what key u use to open the special 2 big black bolts ?
@@WissQuattro The module was less than £25 from what I remember so I chose to just swap the part rather than spending time opening the unit up and hoping that it worked when it went back together. You will need an 8mm spline bit, sometimes called a 12 point or 4 square bit to remove the lock from the door.
The rear driver side handle on my A4 avant won't spring back when door is opened so the door won't close unless you push the handle back into position. What might the problem be and how do I fix it please?
It could be a couple of things but make sure the handle isnt sticking on anything and if not, open up the door and make sure the plastic cable that goes from the handle to the lock is properly located. At 11:00 in the video you can see this cable and how it is mounted. If the yellow part is not properly located the tension on the cable will be wrong and wont pull the handle back against the door.
Thanks so much my friend. Great easy to follow video. My door locks and unlocks good as new now. Just in time before I sell the car in a few days time 😁
Thanks a lot for the perfect video! It was an easy job after watching this. Replaced it with an Ridex piece, works perfect. Greetings from the Netherlands.
Clearly they haven't improved the reliability of the lock modules - but at least they've made an access panel so you don't take the window out. Turned a 2 hour job into a half hour one. Thanks for uploading the video.
I had to do 2 in one week. The one on the Audi shown here and the one on the 2002 Polo (there is a video of that on my channel as well). Had to dismantle the entire door on the Polo so was really happy when doing this one that I could get it out so easily.
Yes, I've seen the Polo video. I did the front lock on my 2003 Seat Leon at the start of lock down. That was the same having to take the window out. Only plus point was I did it while the door still opened.
Thank you for this very informative video! I fixed my door…but the car still doesn’t make a noise or flicker the lights when I lock it. It used to do that, not sure why it works but not completely.
Glad it now locks and the video helped. My car has never made a noise when I lock the doors but it does flash the indicators, dont know what would have changed the settings on your car by changing the lock. Maybe see if there is a setting in the MMI menu?
@@AstonishingGlasgow Thank you for that tip I’ll look into the MMI. I have a 2009 Audi A4 Avant. Yeah it’s weird how it doesn’t do those two things anymore. I decided to just leave it like that…as long as the door locks I am pleased haha
Very good video with quality image explanation. I have to replace 2 rear locking doors on mine so I believe now that it is not so complicated. Thanks you
i have to do this but for my model b8 2009 salloon there is 2,,,,,,,,,,, 8 pin chunk or 5 thin pin connecter ,, ,hopefully i can get he connector off with out taking the lock out and get a look at the pins :( then i can order the right one :)
Thank you for the video, it's very useful! What is the size (number) of the triple square bit you are using to unscrew the two bolts holding the actuator?
If repeatedly locking and unlocking the door while pulling and releasing the handle has no effect you will need to remove the door card from the inside while it is shut. It will be a major pain but may be the only way as seen in my Polo rear door lock video; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-X-uIu6KfoV4.html
Hello. Thank you for the tutorial. But I have a question. What is the tool you use to remove the screws from the lock? It isn't a torx key, because I tried and maybe that I have damaged the screw. Somebody told me that it was a XZN key. Is it? What number? Thank you for your help.
To remove the lock module from the door you will need what is called either a spline tool, a 12 point or a 3 square bit (I call it a spline bit but they are called other names). I cant remember right now what size it was (may have been an 8mm) but a set of spline bits is not expensive and great to have in your tool kit.
You may need to try and pry the door card off with the door shut in a similar fashion to my polo video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-X-uIu6KfoV4.html
Its most likely the lock modules which will need swapped out but also check the wiring loom as it runs from the car body into the door. As it gets old it gets brittle and can split the wires.
The boot wont be an MOT failure. The rear doors only recently became a failure for not opening so that in an emergency passengers can be released from the car.
For the rear left door (same as the video) the part number is 8K0839015. However, slapping this number into ebay can return 2 parts. The shape is slightly different and the electrical connection is either 6 or 8 pin. Search for the part number and pin config to get the right part.
Hi great video, I have a problem on my A4 b8 where I cant open the door from the handle and there seems to be no tension. Can only open door from inside. Have run carista OBD reader - no errors re actuator. Years ago I think I had same problem with my mk2 golf - could it the metal hanger part that goes into a plastic gromet has popped out? Thanks in advance
At 2:35 in the video you see me removing the cable that connects the handle to the lock. It might be the ball on the end of yours has worn off as it's only plastic. This may account for the lack of tension in your handle as it will no longer be operating the lock. Either way I think you will need to pull the door card off for a look.
@@AstonishingGlasgow hi thanks for the speedy reply.. I tried to think about this logically again the issue with white plastic grommet was from the inside on my mk2 golf. I did some more searching on RU-vid and my fix was this - unbelievable - keep door shut and hammer fist under neath the door handle repeatedly. This has fixed it. I will find the video and link it here if that's ok?.. I think it's due to the cold weather.
That sounds like the lock module is about to fail. If you look at my other videos you will see I had to replace a door lock module on my Mrs' Polo. This had a fault just like yours. It worked by banging the door or working the lock button repeatedly until the day that it refused to open no matter what. I think the brushes in the small electric motor start to fail and hitting the door vibrates them slightly until they work but this dosnt work forever. Its a lot harder to replace once it refuses to open.
@@AstonishingGlasgow thanks for this info. As others have said your videos are great, straight to the point . Please keep up the good work. Many thanks !
Thanks Mike. I am really glad people find them useful but for me its a double edged sword. I love making the videos but I need parts of my cars to break before I can. Hope you get your door lock working.
I would use a multi meter to make sure there is voltage getting to the module when you press the lock button. If there is, there is a good chance it's down to faulty modules. I think the one I bought was around £25 so not hugely expensive to change them. Hope you solve the problem.
I have a similar looking fault on my front passenger door, it feels like there’s no resistance on the handle when you pull. Mine will only open from the inside, although it did start working fine again for a short period. Does it sound like the same fault or is there any way the handle could have come disconnected from the internal workings?
Nothing prior to offering somebody a lift and they couldnt get in. I leaned over from the front seat and it opened so the next day I had a look and found that the door opened from outside once it had been opened from the inside.
The 2 bolts that hold the actuator to the door are spline bits. If I remember correctly they are 8mm spline bits, sometimes known as 12 point or 3 square bits.
Did you use an oem part or a third party part from like eBay or amazon? I read some things that said the third party door locks will not chirp and flash lights when locked.
Bonjours ma question es la suivante j’ai une Audi A4 b8 v6 et je voulais savoirs si l’opération que vous avez effectué servirai pour mon problème qui es le suivant la voiture une fois verrouillé les portières arrière ne se verrouille pas.
Je soupçonnerais que c'est la même pièce qui est défectueuse mais je ne peux pas garantir. Ce n'est pas une pièce chère, cela vaut donc la peine d'essayer. J'espère que cela fonctionne pour vous.
Does anyone know what causes the failure? It opens fine from either side but it will only lock on occasion. I'm wondering if there's a way I can fix the broken actuator rather than fully replacing it as it seems like it's likely a bad electronic connection to me.
I'm sure the module could be fixed, failure is usually down to the motor brushes in the module but for me it was easier to spend £25 and have the lock swapped out and working rather than the car be off the road while fixing a lock module.
I would go back through all the connectors and make sure they are fully together. Pull back the rubber grommit and check the wiring as it passes from the car to the door and make sure your carpet is dry as there are control modules in the floor. If these all seem fine, get hold of vag com/ vcds or a fault code reader to see if it brings up any codes.
For less than £30 for the new lock module it was easier to swap components. I is easier for me to complete the job so that the car is available for use then fix the old module whenever I want and have a spare.
