Simple replacement of the pogo pin battery connector board
The pogo pins that connect the battery to the derailleur are very fragile and will fail (mine have) - typically just after the warranty runs out. The pogo board is easily accessible but no end of googling can find the correct spec pogo pins to replace the failed pins, much less a complete mini board with a plug in connector so skill at soldering is required - even if you can find the right pins. Google also points out that this is a VERY common problem and SRAM are less than helpful once outside the warranty period. A simple plug in connector of the pogo pins is all that's needed, where is it ?

Hello jt27516@gmail.com,
Mr Google says SRAM will not repair (quite a few posts on reddit etc), and neither will most bike shops - they want to sell you a new one!
If you can solder then you can replace them yourself. Finding the same size pins is not easy though, I eventually found some from RS online (data sheet attached) which are pretty close. They are made by HARWIN manufacturer part number is: P70-2100045R
The link to RS online: https://uk.rs-online.com/web/p/pcb-sockets/2479187
Getting at the pins is pretty easy, the 2 screws on my XX1 AXS are Torx T5 and everything just pulls out after that.
I did think that since soldering skills are required then a good local electronic repairer or remote control car/plane builder would be able to do it. You may also find a mobile phone/computer repair shop that will do it for you.
To get mine going again quickly (before I found a pogo pin stockist) I used 2 pins from the battery charger. To get this apart, there is a T10 Torx screw under the label stuck on the bottom, on mine the screw is above the serial# at the left hand end. Eventually, (when all of my batteries were flat) I fitted the new pogo pins in the charger.
Good luck!

one of the pogo pins broke off in my GX Eagle rear derailleur and now no green light when the AXS button is pressed, no connection seen in the AXS mobile app and no shifting is possible on a bike that's only 26 months old. What are the repair or replace options ?

Oh, and even if the pins fail inside the warranty period, dealing with your lbs to get a replacement / repair under warranty will typically take 4 to 6 weeks - so you won't be able to ride your bike, which is totally unacceptable.

PS, if the solution is to buy a whole new derailleur for the sake of duff pogo pins then I'll be spending my money on Di2 instead.
