Just signed up to say thank you! This thread was the solution to my problem as well 😄
Same exact car as Scotty, and the same wire broken in the same spot:
I pulled it out, threaded a new one through the sleeve, reattached the ends with terminal blocks, and everything was fine.
Basic stuff for anyone who ends up here in the future:
- Yes, the sleeve can just be pulled out of its socket using enough force, and squeezed back in.
- You can open the boot mechanically using the key. The hole is right next to the boot button.
(The latter might seem obvious, but in another thread, the discussion revolved around crawling in through the back seat rests to troubleshoot.)
