W211 Common Problem - Trunk Wiring Failure
HTML-код
- Опубликовано: 15 окт 2024
- In this video I show a very common issue with the W211. My 2008 Mercedes-Benz E350 is being used for demonstration.
Here you will see the issue, necessary disassembly and tools required to remedy the issue. It does require basic wiring repair knowledge which is not covered in this video.
Use of the material shown in this video is to be used at you own risk as I am not responsible for any damage done to your vehicle from use of this information. This procedure should only be done by trained and experienced automotive technicians.
Enjoy! Thanks for watching!
Oh man you saved me a lot of hassle and frustration that I couldn’t fix this problem for the last 6 months . I checked each and every fuse since that was my suspicion to be bad. Thanks thanks……thanks. 😊
You covered all areas of this job; I have no question in mind remaining. Excellently taught, thank you 👏
My brown wire just broke now and this video helped, thanks. It is amazing most other videos on this issue always were caused by the broken brown wire, not the other ones. I think there is a design fault here but Mercedes is not willing to do a recall to fix this common problem 😦
This was SUPER helpful. To remove the 12 volt outlet, unscrew it from the back side. To disconnect it you will need to cut the zip tie, open it up like a clam shell, and then pull the connectors out sideways. Also, my trunk would not open until I used a screw driver, to simulate latching it.
Well, you hit the nail on the head! The wire was broken exactly where you said it would be. Great tip, and thanks for saving us $$$$$$
Glad to hear the video fulfilled its purpose 😁🙌
Did you have a zip tie holding the wiring down, as well, like this guy? Take it off & leave it off. It doesn't need to be there & hence you shouldn't have had a problem.
Thank you. Great tips. 2 wires were broken in my case on my E280 2009 model. All the wires was housed in a black conduit cable sleeving tube. The problem is the conduit cable tube has been broken into 2 pieces and become the bending point to cause the wire to break over time.
My trunk just started doing this . THANK YOU 🙏🏾 FOR THIS VIDEO. I thought i was gonna have to throw the whole car away 🤦🏽♂️🤷🏾♂️😄😄💯👍🏾~ great job
Awesome! I’m glad it helped!
Thaaaank youuuu. It was the brown one, it was cut like it was done by a human. Everything works. Now im afraid i have a rat in my car. Thumbs up for you
No problem! Glad the video helped. They’re always broken flush like they were cut. It’s just from consistent bending in the exact same spot. Shouldn’t need to worry about a rodent, unless there is evidence of droppings in the car
Wow… exactly same thing. Both license plate lights, 3rd brake light and then the handle no longer worked. Thank you!
Thank You ! It was the Brown wire indeed and i fixed my light in the trunk as well !
Thank you so much, my brother car has the same problem, your video was very hopeful, truly appreciate it!
You’re definitely welcome! Glad it helped!
Thanks bro, I had the same problem, fixed it thanks to you 🤙🏻
Glad to be of service ✌️
Thank you for taking the time helping us.
You’re definitely welcome!
dzięki tobie zaoszczędziłem czas i pieniądze pęknięte 2 kable Dziękuję 😊🤜🤛
If Japanese cars are not having similar problem of insulation going brittle then Mercedes are using wiring having sub par plastic materials. It is possible they are blending in too much % recycle plastic when making their wiring?. This would be a consideration for class action lawsuit?.
Thank you saved money on lock motor .
Good stuff! ✊🏼 Anything on water intrusion in the trunk?
Thanks. I am having this exact issue on a 2005 wagon.
My 211 e200 facelift failing to comunicate with diagnostic machine, tried changing central gateway, changed CAN and computer box, we even changed lock system the problem still persists
Yes sir, if you have this car you for sure have broken cables in that area. I ones found several in that area missing insulation.
Same problem ill check the wires.Thanks
Cool, love watching those vidoes
Thanks! Glad you like them. 👌
Thanks alot, i had same issue with the same brown line, thnks for tour video
Hey I tried to do this then my driver headlight stopped working and changed my bulb but nothing
Have exactly the same problem no 3rd stop light, no lock, no registration light working and those inside as well
Just wanna add that thanks to your video I've managed to solve the problem with a plaster and some glue;) Thank you brother
Thanks mate!
BTW, you can join the wiring by simply twisting the two halves of the bared wire together & insulate with heat shrink, NOT electrical tape, as tape can start falling off with age! Simple fact!
Nice video my w212 have the same problem
Great video thanks! 👍
Any Links For The Butt-connector And Cover You Use?
I recommend this for pretty much any automotive wire repair. They’re solder butt connectors and heat shrink all in one. amzn.to/41jEGKc
Did you change the whole broken wire or only part of it? Since it is not easy to change the whole wire .
Just clipped off the stuff broken parts of each side and reattached with a small section of wire
@@MercedesTech Yes I got it . Many thanks!
Nice video thanks
Thank you for helping 🙏🙂
No problem!
With the broken wire, does it make a whirring noise? Mines makes a noise just doesn't open
That’s more likely an issue with the release mechanism. The broke. Ground wire as shown in the video is usually apparent when 3 things happen: License plate lights out message/ license plate lights not working, trunk doesnt open without key and interior trunk light (mounted to trunk lid) doesn’t work
@mercedestech9194 thank you very much. I'll open her up tomorrow
thank you men
Sir, my pass. rear window switches dosen't work, the rear windows can only be controlled from the driver's side. Need help on way out. Thnx.
Usually if the back windows are not working only it’s the driver door switch having an issue with its rear window lock switch. If it’s just one window, it would be that switch or regulator
Hi ! My 2008 W211 trunk cannot close completely, there is nearly 1 cm gap after closing.
Luckily, there is no leakage. Do you know how to fix it?
Is this a power trunk or manual?
@@MercedesTech
it's power trunk
Likely the cinch actuation within the latch isn’t working. Would recommend looking into how the cinch actuator works on that car. My E350 isn’t powered so I’m not to sure.
Thank you✊🏾
Is it necessary to disconnect the battery before repairing the broken wires?
It’s always a good idea but not necessary. Just want to be sure not to not let an exposed (stripped) power wire touch the metal body anywhere. Otherwise there could be sparks and you might pop a fuse
@@MercedesTech I fixed it. Thanks.
Tx! Really helped.
I haven’t looked at this yet but my third brake light and my power trunk doesn’t work and after reading on forums many others have had the same problem
This is very likely your issue
@@MercedesTech okay I found the broken brown wire but when I touch them together the alarm goes off and the lights come on will it cause a problem if I solder the wires together or is the alarm just part of a safety feature and should I just disconnect the battery solder the wire and reconnect it
Edit: I said whatever and taped it but now the only problem is the trunk is unlocked every time the car is unlock even if I don’t press the trunk unlock button, and the trunk unlock doesn’t do anything
Sounds like something else is going on. Be sure to check the same bundle of wires for more broken wires. There are often more than just 1 broken. Be sure of course you have the same color wires taped together and that you got them all.
@@altofant got any updates? I’m curious lol
Bro you’re fricken cool❤
😎
Ayye just wanna cosign. I sent buddy this video and he came over and we got it done in an hour or two. The wire was split in half under some electrical tape / zip ties. Thank you ! 😇@@MercedesTech
I think that’s the problem with my rh license plate light on a Wagon
Could be, very common on 211 sedans. But pretty much applies to any make or model door wiring. Sometimes they just break over time from opening and shutting and heating up and cooling down hundreds of times
@@MercedesTech wanted the wiring diagram for my W211 wagon but couldn’t get it anywhere.
Yea it’s hard to get without StarTek Info or a service like Alldata. Sometimes those things can be found online in forums and such
@@MercedesTech I checked my RH license plate and find out there is no power to the wire and that wire is coming from the module, so what I did was just eliminate the wire from the module and join together with LH side license plate light which was working. So I’ll just live with the RH side error warning ⛔️
@@mzee5533 Nice 👍 at least you got it working. Perhaps there is a break or short to ground in that wire somewhere in the car. Or something wrong with the module.
Your problem was the zip tie which actually tightens the sharp angle for the wiring to drop into the area intended by Mercedes, who never put a zip tie on the trunk bracket. I've got a 2003 W211 E320 which is 20 years old. It has no zip tie & the brown wire never looks like breaking. The zip tie can actually cut the wire over a number of years & this, my friend, is your problem. Mercedes actually have the wiring routed down the underside of the trunk bracket, held in place by clips pushed into holes in the bracket. This is NOT a common problem on the W211 if you don't interfere with the wiring. Take the zip tie off & leave the wiring alone, as Mercedes intended!!!!!
Uhh, ok?
@@MercedesTech Maybe Uhh,ok? to you pal, but I've owned Mercedes cars (3) off, for a number of years, all sedans, a W124, W203 & W211 & never a problem with "trunk wiring". Obviously somebody couldn't keep away from zip ties & the result is broken wiring. End of the argument!!!!!
