2018 e400 Cab top and headliner issues

I had my car in for regular service and with the above they replaced the strings and headliner.




This will be the 4th time in the shop for the same issue. My car has 20k miles, so every ~5k miles the cords fray. It was longer this time due to covid. Fortunately still under warranty. I'll probably sell the car after they're replaced the next time, because there will be a next time. It takes at least 3-4 full days for them to fix it each time the cords fray. It's a web of cords.
The part number is still the same for the headliner, so that's not encouraging. I tried using the part number from the guy in Shanghai for the replacement cords, but they said they can't get that part here in the US.
The instructions on fixing the issue posted upthread are complicated, so perhaps my dealer isn't doing something right? It just seems like a design issue to me. It's frustrating because I like the car otherwise.

Just picked it up 7/8/22. All my concerns including the fraying cords were covered by CPO warranty. These are what the repair cords look like in mid 2022. The ones bound by black tape I know were replaced.
It's a good day!

I'm going to be focused on making sure it doesn't enlarge the string enough to cause issues and be sure it can't come loose or the cord start to pop out. It should be pretty much invisible if it works.

Good news and bad news. First the bad - the wrap around the cords seemed to work really well at first, but after a few cycles, the cords started getting stuck in the eyes. The wrap just made them a little too thick. So now the good news. I went ahead and took the plunge, bought the needed parts, and did the full job this weekend. It went slowly but worked out very well. I'm pleased with the result. I took multiple videos in the process and am in the process of editing and adding notes in there for anyone else who wants to try it. All in all, this is a $100 job if I have to do it again. First time through I had to buy a couple of tools. It also took about 7 hours of garage time to complete. As suspected, this was not rocket science but was tedious and required some good basic car knowledge and experience. Not a job for a newbie or impatient person. Video to come soon!
