Mercedes Door Lock Repair - Bouncing Issue Fix

This was done on a 2002 Mercedes C230 Kompressor Sport Coupe. The issue of the door lock bouncing up and down affects the W203 C-class and W211 E-class models.
This is the repair kit I used. amzn.com/B00Z1OY30I

Still helping 7 years later in 2023! Much appreciation for your time to help us!

[@adogmcdizzle]

This video is still helping people in April 2024 - Thanks for the close up views, everywhere else the slot/hole distinction wasn't explained as I was in doubt I was doing it correctly.

[@timdee2981]

Thank you so much. You described the problem I am having with my car exactly. The local Mercedes dealer carries a sharp curved chisel in his pocket ... It's called a gouge and he uses it very freely to extract as much money as possible from unsuspecting customers.... You help us all to free ourselves from people like that. Thanks again. Tim

[@lawrencedunn]

You just saved me hours trying to figure out why it would unlock but not lock after the repair test . Can't thank you enough!!!! Also for anyone that still has a bouncing lock after swapping the spring. Don't lose hope, this just means that you stressed the spring too much getting it in, and you need to use a new one.

[@karenmargaryan7548]

I have the same problem)))

[@NazifNB]

good job unbelievable how you fixed it on the car,great video, and thanks

[@fernandolopez7029]

Great video. Don't worry if the camera moves a bit or the view is not optimal, but the advices are really good. Good job and thanks.

[@alexalexanberto3479]

Thank you very much, I forgot about this button and spent the whole day racking my brain while checking for functionality before installing the lock back, why it opens but does not close the lock. 😂And I couldn’t find a video with this tip anywhere on KZbin.

[@jefferykaighin7039]

Brother, your a God send! You have saved me a world of AT&T (animosity trouble & tension) and Time!!! Thank you again for this video especially since im working in the cold in Kansas! Great Video!👍👊😁

[@markholbrook7482]

You're a star. Just bought a C class and it's started doing it. On the test drive the auto door locking was turned off otherwise I would probably have noticed. I watched your video and my door lock nightmare just ebbed away. Now if only I can find a video on window Motors to my other C-Class

[@cango75]

I really wish I'd watched the whole video first! Fell right down the same hole as you, tested half way through and found it would not lock! Thanks for including that vital bit of info. You really helped me out!

[@mikenewbry]

Ah, someone knows my pain. Sorry dude.

[@cango75]

+Profectus Don't apologize, I only lost a fraction of the time you did because I watched the whole video after scratching my head for a bit :-) without your tutorial I'd have been stuffed. So thanks again :-)

[@markholbrook7482]

Your method works with the coupe as the doors are longer and the rear speakers are conveniently in the rear corner of the door. On the sedan, the rear speakers are in the parcel shelf so it would have to be your rivet replacement method instead. This clip is 5yrs old and still doing great service. 👍

[@mrmuhtish]

Not the model I have, but have the same issue. Wanted to say thank you for taking time to put this video together.

[@WineScrounger]

Same problem with my W169 A-class, one of those jobs that takes 2 hours the first time and 30mins the second time. Nice video, thanks.

[@WineScrounger]

Just thought I’d add that on the W169 the lock mechanism and window regulator is all mounted to a pressed steel skin that is riveted to the inside of the door. It’s a pig of a job if I’m honest. You’ll need to take out the window glass and everything.

[@WeeShoeyDugless]

Changed a few of these over the years, the W203 is more accessible. Got a rear door to do on my brothers W203 in a couple of days time. I find it easy now, just practice I suppose.

[@farzinghodsi622]

Thank you for your brilliant video. I have searched and found very few related videos. However yours is the best and very helpful. With Gratitude, FG

[@souprememc]

Thanks bro. G500 door locks are really a pain! I promise, every 6 months one breaks or malfunctions. My wife loves it cuz the passenger side won't open from the inside so I've become a perpetual gentleman walking around every time we park and letting her out from the inside 😣🤣🤣

[@Mr-sc8dq]

amazing, this happened to my dads CLS 320 ws19 , only drivers door though, this video is so straight forward and simple, even if the process isn't exactly the same on my dads car " makes me feel slightly" better that its a common issue" , awesome straight forward no messing about vid

[@LiamRoberts00]

What a fiddly job, once you've done one you can do it all day long, great video couldn't have done it without you!

[@littleand9250]

Thank you so much!! Just got a w211 and sometimes I give up and just leave the car unlocked at night. Wish me luck going to try this today!!

[@Casmige]

Got the kit! Follow the directions to a “T”. Get it all back together and in place and decided to test it. Everything worked sorta but the mechanism and what I mean by that is I could hear the little servo whining/whirling??...But the lock rod was not going up and down. Took it back all apart and found out that there’s a little intermediate gear Between the servo & the big white round gear.....That had broken and falling the fuck out!!!. Grrrrrrrrrrrrrrr!!!!!. What I found was if you get the mechanism down into the speaker hole and just be a little bit forceful with it you can pry it out of that entire speaker hole....Keep the unlocking dogleg metal piece that the outside door handle actions upon?, pointed down at 6 o’clock. Of course you do have to take the cable and the locking/unlocking rod off before attempting this.

[@kellyfarlow4285]

I don't care at all how long the video would or could be, because I would be in the fix way longer if it wasn't for your willingness to help us the do it urselfers! Thanks for your action on details!

[@jamesmanser6385]

Thank you for your time on this. Very helpful.

[@civotbree4900]

GOD BLESS YOU SIR

[@jasonhaug8653]

[@16wayno]

[@sandymclea]

Thanks, great video, you probably saved me hours, gonna give it a bash!

[@abdallahibnqassimibnabdull7270]

thanks man, it did. thanks for the video and time taken to help.

[@paulryltonfawcett9043]

Thanks for your video it was a great help.

[@tserevenad]

very helpful video. After trying to replace the spring, I gave up and am now installing a junkyard part (tested good). but after getting by every complex puzzle challenge this project has I am stumped with the plastic shield inside the panel that goes between the exterior handle and the lock/actuator. Can you comment on this? I can't find any info on this anywhere on Internet.

[@tserevenad]

oddly minutes after I posted this, I tried to install the actuator yet again and it slipped right into place. bizarre, but door all together now and works perfectly. What a challenging project.

[@javiercontreras1771]

Good video thanks very helpful.

[@mcdonellewen]

Excellent video. Thank you.

[@putianren]

Great tutorial. Thank you.

[@nelias7306]

oh man I remember doing this on my 03 w211 lol. it was a pita. I drilled out the rivets that held in the track and rerivetted it back in luckily

[@andrewwg94]

Can confirm this fixed it for me. Although the new spring was impossible for me to get in position without trimming the top side just a bit. Hope that helps someone

[@henrylong45]

"... Although the new spring was impossible for me to get in position without trimming the top side just a bit..." WHAT??? What are you talking about? Trimming the top side of WHAT?

[@yalincaglaroncel7893]

Great video mate, thanks a lot.

[@aldertboonstra4521]

You can simulate the spring by pushing a tie rip in the doorlock. Most effective and easy fix for this problem! Holds fo ever! Done in a minute!

[@tahael-hazzouri1225]

aldert boonstra what do you mean ??

[@Casmige]

Ordered the kit from Amazon but in the Mean-time?? Couldn't actually lock the car up..... Read the comments section &? Fucking Hell the Zip-Tie Hack??..... worked like a damn charm!!!!! Took a medium Zip-Tie...threaded it in-between the door-lock button & the collar it sits in & just inserted it all the way down with the zip-tie box-end facing outward away from the button. Hit the lock button, tried the door & Voila!! NO FUCKY OPEN WITH ALARM GOING OFF!! Thanks HEAPS Aldert!!

[@anastasijateodora3025]

how do you mean Tie rip in the doorlock? Please explain? Regards from Serbia.

[@smukkeanton5110]

Mucho Gracias.... you are a genius!

[@davewatt28]

Really appreciate your video thanks very much

[@Gabriel-lp2jv]

Perfect! Thank you,very much!

[@Johnson8.]

Love your video

[@junkspam9513]

Great video !

[@MikeIgartua]

Hi, I took mine apart today and there is this plastic piece behind the actuator with a hood, I had a lot of trouble lowering the actuator because of that. Then It was nearly impossible to put back in place because of that same plastic piece with a hook in the way. I cannot find a diagram anywhere on line how that piece goes. Under, behind or above the actuator? Do you have any insight on that? Thanks! God bless.

[@alternativlos12345]

Thanks from Germany :)

[@henrylong45]

Good video!

[@zanda677]

Dude, your brilliant I have the CL203 C220 with very low mileage and she is 14 years old, in mint condition, your the only video to have showing the coupe door and yep its a bitch I have been trying to work out how to do this job but with your help from across the Pond, yep im here in the UK you have just solved the problem for me, Thank you so much.......... :P

Great! Thank you so much! 😊

[@LudwigAmadeusVanDerMaas]

Thanks from Germany.

[@owneyme1024]

Enjoyed the video. I have a peugeot 206 year 2000 and i have the same bouncing issue...so is the spring the problem??

[@haroldmilerAmayor]

My door lock on the passenger side does not go up and down whatsoever so if I can find a video that shows how to fix that problem it doesn’t bounce it doesn’t do anything you can’t locket there or nothing it’s frozen unlocked

[@killerhertzmercedes]

great video thanks, can you confirm what springs you searched for on Amazon?

[@mikenewbry]

This is the kit amzn.com/B00Z1OY30I

[@killerhertzmercedes]

+Profectus cheers

[@HGHONDO]

THANKS!!!! I'll be working on this along with a check engine light that loves to come on every hundred and sixty miles

[@alancruickshank9981]

If it doing it on both off side door do that means got to do both door

[@WalterWeakley]

thanks, i have the same problem

[@brotom5398]

Hi Profectus, thanks for the great video. Please, the external door handle of my 2001 c240 (for the right side passenger (rear)) appears to be coming off. How do I fix it? Please, do you have a video that could help? I can't find the screw that attaches the handle to the car.

[@mikenewbry]

Sorry, I've never worked on a 4-door, but I would look for the same torx bolt behind the weather strip as you see in this video

[@DoXToRs]

THX I fix it just like You

[@minhly6387]

This was tough, the ml320 w163 has a large spring, some moron mechanic use this spring on my ml320 and it was a total failure, didnt work at all, make sure they use a large spring

[@LudwigAmadeusVanDerMaas]

Gute Erklärung.

[@tracywalker1446]

So is the "bouncing issue" only a cause from the spring in the actuator? I was also told to check the sensor behind the tire. Does that sound right?

[@mikenewbry]

If it's a fast bounce it's the broken spring. If it's a slow bounce it's an electrical issue.

[@KeeganTV]

Thats a speaker hole, wheres the speaker? in the door panel right?

[@JesusDisciple916]

You didn't show how to get the spring out. Can anyone help with that?

[@tigar0304]

My B class 2012 same issue. First front passenger door lock whole panel replace 350£ ,and then back door lock start to bounce . Spring replacement 80£ . Rubbish

[@walangbuhok1]

Known issue? Recall?

[@ruwannanayakkara2137]

Hi, Could you tell me the right spring to buy please.

[@mikenewbry]

Link is in the description

[@KeeganTV]

If I lived close to you Id pay you do to this for me. I know its not going to get done cheap around here...

[@Titanic19127]

I need to do this on the passenger side on my E350

[@kvEik]

Man, i knew it would be a hassle, but damn, got a man crying over here... and all that hassle for the worlds smallest spring in a molded plastic part... 🙃

[@sdmnchannel9738]

Thank you man, God bless you 💪🏼💪🏼this video helped me fix my fucking c Door 🤣

[@timwright3790]

Albert boonstra:: what is a "tie rip"??? Do you mean a zip tie?

[@aldertboonstra4521]

tie-rib, tie wrap

[@aldertboonstra4521]

see this link: www.lpgonderdelenshop.nl/Tie-rip-20cm-1

[@ioanardelean1936]

I am number 1000 (1k) like😂... Round number... Great job video.

[@ahchoen]

All because of that little spring? Haha

[@aldertboonstra4521]

You don't have to dismantle anything. Just push a small tie rip in the same hole as the button which goes up and down. Because of the resistance you have created, it will work exactly the same as the spring. Just try it.

[@jimmylai6022]

Hi aldert Im having issues with my door locking, cant you explain how to do what you are mentioning? that will save me alot of time and energy. Thank You!

[@aldertboonstra4521]

if you could sent me your emailadress i can sent you a pic

[@jimmylai6022]

[e-mail] thank you! :)

[@Elite1inamillion]

Jimmy Lai hey jimmy can you please lmk if it worked? if so foward me the pic, please. thanks

[@jimmylai6022]

it worked like a charm. a few mins that can save you countless hrs and probably hundreds, i have no issue doing the fix as im quite competent but with the lack of time this definately allowed me to lock and unlock. shoot me your email and ill foward a picture and descript to help you GL

[@deezynar]

Just face it, power locks are nothing but a failure waiting to happen.

[@azam9271]

hi mine have coolant in engine oil..how to fix it?

[@mikenewbry]

Push it off a cliff. It's done. At the very least you have a blown head gasket.

[@dawnnowland7300]

just happened with my bmw X5... All the radiator fluid in the pistons was causing it not to start / 5 minutes to start. (blown head-gasket)! USED some BARR's HEAD GASKET FIX - $30 from Oreilly's -- FIXED! (for 9-12 months, then should probably have to do it again).... A JOKE: A vacationing penguin is driving his car through Arizona when he notices that the oil pressure light is on. He gets out to look and sees oil dripping out of the motor. He drives to the nearest town and stops at the first gas station. After dropping the car off, the penguin goes for a walk around town. He sees an ice-cream shop and, being a penguin in Arizona, decides that something cold would really hit the spot. He gets a big dish of ice cream and sits down to eat. Having no hands he makes a real mess trying to eat with his flippers. After finishing his ice cream, he goes back to the gas station and asks the mechanic if he's found the problem. The mechanic looks up and says "It looks like you blew a seal." "No no," the penguin replies, "it's just ice cream."

[@icesystem7]

German engineering...

[@ickyyes]

The easiest fix is this. kzbin.info/www/bejne/fWKQp5uKd9SZm6c. No need to remove the door panel and all that.
