These tend to come off when opening door too quickly, the drum struggles to keep up throwing the cable off.

Reinstalled mine after looking at the other side which was still attached, your design maybe different though.

Not recommending you do this yourself if uncomfortable with overall operation, it takes some working out as to what does what.

Personally, I hate springs and go to great lengths covering up with safety goggles and so on, this weekend put a new aux belt drive on my 124 - releasing the spring on that stood well to the side lol.

Going back to the door mechanism, mine had no lube on, might go back and grease the wires unless not advised.
