Hi everybody
Like all on this forum, I had the same issue that one of the pogo pins' small little spring inside collapsed (the + node, seems to fail in all cases carrying more load than -).
I can share a solution like another also found on this forum. I ordered these pins from above link at https://za.rs-online.com/web/p/pcb-sockets/2479187?gb=s per @guidodg (thanks for that). You get 5 and it cost about R100 for the strip plus courier so R250 total. You need a solder iron and some solder, pair of tweezers, a T6 Torx screwdriver, good eyes and a steady hand. Unscrew the little torx screws, lift the rubber plastic plate, be careful to not lose the little screws, when they fall it is impossible to find them they are so small. Unsolder the old pins from the little pc board, re-solder the new ones, make sure they are square, and that worked for me. A R250 fix. The bike shops weren't offering any solutions other than expensive ones. So I'm afraid this is a DIY job. It's a bit of a schlep, but worth it though. There is a video on this thread of someone harvesting pins from a charger which would also work and the workflow is the same, the charger is just much more expensive than the pins bought seperately.
Good luck
