- This video shows you how to replace the decklid or trunk wiring harness on a 2013 and similar VW CC.
The part number for the wiring harness is 3C8-971-182-G. I got mine from ShopDAP.com for $91.57 in October 2020.
Ask any questions you may have in the comments section below, and thanks for watching!
Thank you for the video. Your video made it possible for me to fix the issue myself. My '14 CC had intermittent issues with the trunk not opening with the key fob, door, and rear hatch. The rear lights were working fine. I ordered the OEM wire harness from FCP Euro. Here are my suggestions:
1. Definitely wear cut proof gloves. This will keep your hands from being cut by the sharp/rigid plastics.
2. I highly recommend using Nylon Pry Bar set (Harbor Freight). Metal screw driver will destroy the tabs. These tools allowed me to unlatch the 4 connectors located in the driver's side rear fender. I used the nylon pry bar to remove the connectors from the chassis. I also used the nylon pry bar to push into the connector. This released the connection tab to release the male plug. Nylon pry bars were also used to remove the tabs located throughout the lid of the trunk and the carpeted wall.
3. I removed the trunk lid liner completely. Remember to take a picture of the manual trunk release for reference.
4. Instead of removing the wiring completely, I pulled through the disconnected wiring harness from the bottom to top (trunk lid). Once the wiring harness was out, I disconnected the old connectors from the trunk lid and plugged the new connectors as I went along.
5. I was able to feed the 4 connectors into the rear quarter by using a blue tape to wrap the wires together. The wires were strong enough to feed without issues.
I was able to put the panel pieces back without issues. Remember, do not force too much when working with the body panels. The metal clips for the trunk lid does move laterally, so be mindful when reinstalling them. I had to adjust few of my metal clips to line up with the slit/hole.
Good luck! Thank you again for the video.
Thanks so much for this! I was able (as a 30 something woman with no knowledge of car mechanics) to do this myself in under an hour. I even used my hair tie to feed the wires through and a cuticle pusher to help get all the clips apart hahaha. Problem solved!!
Thank you so much... the dealership was going to charge me $400 for labor and $189 for the part... ill take my chances with this video and repair it myself
Nice! I’m going to do the same, self repair. I appreciate the quote on the price.
how’d that work for you? easy?
@@othmanxNot sure if you have done yours yet or not but just finished mine and it took about an hour but not that hard. Just need to be careful not to break the plastic pieces in the trunk liner (broke both of mine).
Thank you so much for posting this video! I just got a ‘15 CC and had a latch problem that the selling dealership didn’t fix properly. I ordered the harness and changed it out today. It was an easy process thanks to your video and it works now!
What's the parts number pls, 2015 CC?
Thank you for this post. I saved paying the dealer for changing it out however I did pay them $$$ for the OEM harness for my 2010 cc. Your tips were on the mark.
Hey sorry to bother, I own a 2010 cc as well, I have the reverse light issue and also my trunk won't open. I think I also have this wiring harness problem. Were you just following along this video while replacing? And how much did you pay for the wiring?
Good job explaining and thanks for the good lighting. To fish the lines back down into the trunk, I used a tool to take the trunk lid off of the arm. It made fishing the lines a ton easier. I had no problems taking the old line out, where you said the little plastic pieces stuck, I just pulled the other way, no snags. All in all, a one hour fix. Cost about $100 for the cable. Who knows what it would’ve cost to get it fixed. Thanks again.
how did you take trunk lid off the arm? i'm stuck at this step. afraid to do anything hasty cuz the wiring harness is delicate.
with your nice detailed vid i got the courage to do this myself and saved a whole bunch of money. thanks so much!
Brilliantly explained and filmed, thanks a million.
Great talk through. Thanks from Scotland.
Thanks Chris! Just did this on my 2013 CC using your video. Very good walk-through of the process. I had some difficulty figuring out how to thread the new harness into the hinge pipe since it isn’t visible, but the socket on string idea helped a bit.
how did you thread the new harness into the hinge ?
Same problem happened to my 2015 cc. After 3 hours diagnosis by dealer ship and they pointed out the causes was due to trunk wire harness failure. Guess how much they gonna charge me.Up to 1500 bucks. And this not the end. That price is just for harness replacement. They say this is just the first step for the further inspection. Now I’ve picked up my car back trying to do this myself .
Thanks for the video. I have the same year, same color with one of my back up lights not working after replacing bulbs recently. Cheers!
Thanks for this Chris...my 2014 CC 4motion started giving me the check rear blub and my backup camera went out. Turns out its the wiring harness. My dealer wanted 520 just for labor,..... paid $98 for the harness (3c8971182J) it has 5 connectors one more connector (blue) next to the rear right side bulb connector for the camera. Again thanks for the walk through much appreciated.
Thank you for including the part number in your comment! I have the same vehicle (2014 cc 4motion) and I've been struggling to figure out which variation is the one I need. Super helpful! 👍
Thanks for this video. I replaced my trunk harness and my trunk started working again on my 2012 VW CC. Yet, the trunk lights are still not working, my dash still shows the trunk open when it's closed, and I'm unable to lock my doors from the inside of the car. Any advice you can give? Thanks
Just what l needed bro ; my rear camera wont work when slamming the boot lol
Thank you for this brilliant video. Quick question, can this cable be repaired? I had tried to repair it but it never work.
Thanks for posting this!
Where did you find the part number?
Thanks!
I need to do this exact same thing on a 2015 VW Polo hatchback, and curious if anyone knows where the connectors to the wiring harness are at the car end. Roof? C-pillar?
The wiring harness goes through to tailgate near the roof, but I don’t want to disassemble panels, and risk breaking something, where I don’t need to.
This is great and very helpful, thanks for it. Pls how can I get this this wire harness, can you help me with the parts number? Great job.
Thanks for this Chris!
Make sure you run it from the top to the bottom. The smaller plugs that end up inside the trunk have to be the ones fed thru the tube. If you try and feed the larger plugs thru the other way, they won’t fit. I even taped all of the smaller ones tightly around the harness wiring (using electrical tape) before fishing them thru, just so nothing got caught up while being fished thru.
Where do I buy the repair manual?
Hi my trunk is not opening my husband is going to fix it do u know what he need to buy? It's an electrical issue
I have a 2013 cc as well, with the same issue. Waiting on my harness to be delivered. I just recently replaced my mirror switch as the knob broke off. Did you notice while your wiring harness was broke if the rear mirror dimming worked or not? I wonder if its related or if its another problem.
I didn’t notice if the rear view mirror dimming worked or not, but I don’t think that’s related. There are only 4 connections on the harness (2 for the lights, 1 for the remote trunk release latch, and 1 for the VW logo decklid release latch), so not sure how the mirror/dimming would be related. I’ve already done the driver’s side door mirror switch and have a video on that one as well on TH-cam. Good luck with the rear view mirror.
@@chrismiller9776 ok thanks. Looks like I'll be replacing the mirror too 😐😐
chris, are you still active? I have had issues with my trunk and it doesn’t work on my key or the button on the driver door, is this the harness?
Thanks Chris. Assuming this part doesn’t include the backup camera correct?
There’s a different part number for the harness with 5 plugs, which is the one you need if you have a backup camera. I think that part number is already listed here in another comment.
what tools do i need for this
I have a 2014 3.6 engine. I suppose the harness would be the same? Does anyone have the part number?
What cable size require?
I have the same problem! The trunk latch won’t work at all! Can you tell me where you bought the harness please?
www.shopdap.com/make-model-year/volkswagen/cc/2013-current/electrical/wire-harness/3c8-971-182-g.html is the one you want if you don’t have a backup camera. If you do have a backup camera, you want this one instead: www.shopdap.com/catalog/product/view/id/502360/s/3c8-971-182-j/category/8986/
Mine is opening the trunk suddenly, could this be same issue?
Same thing, even when i shift in reverse. Did you fix it?
May i ask how you attached your rear view camera?
Our 2013 does not have a backup camera. For vehicles with a backup camera, there is a different wiring harness which has an extra connection/plug for the backup camera.
I have a 2010 cc. The older shape. Is yhe harnes the same for all models?
I have a 2010 as well will it work the same way?
Yes, the 2008-2012 model (VW Passat CC) is the same as the 2012-2018 model (called only VW CC)
I tried running my harness through the cylinder tune and the first connector seems to be stuck on something inside. This happen to anyone?
How do you replace the bulb for the rear light light of a 2013 VW CC
Can someone assist me with my question?
Depends on which bulb needs to be replaced but they’re all done similarly. Determine what bulb needs to be replaced, remove the old bulb, and replace with a new bulb. If it’s one of the bulbs on the outside edge of the CC, you’ll replace it thru the inside of the trunk rectangular opening. If it’s one of the bulbs on the trunk lid, you’ll replace it thru the rectangular opening on the inside of the trunk lid. Here’s a link to another video I found on YT for replacing a halogen bulb on a CC. th-cam.com/video/gOh_L-pWFAE/w-d-xo.html
If you have LED bulbs instead of halogen bulbs, it will be a similar process and done thru the same locations. Just the bulb housings will be different. Just turn/twist the bulb housing to remove it, then replace the bulb, then turn/twist the housing back into place.
Did yours have a back up camera on trunk logo?
No our car didn’t have the backup camera. Some of the CCs do, and that’s a different wiring harness & part number with 1 more connector than ours had.
1:36 Those are plastic screws. Remove them with a hex driver. Do not pry them. Or you'll end up destroying all of them like I did.
I pried all of them and had no issues. You only pry out the center/middle section and not the entire plastic clip.
And the dealer charges 700 bucks to do this job
Can someone send me a link where I could buy the wire harness for my volk 2013 volk cc

Hey Chris, thanks for the vid! I found the same part online, as I’m having to do the same thing to my 2012 cc. Is this the right part number? 3C8971182J
How did it go with the 2012 cc?
