Strange goings on with my scuf infinity! Help!

Hi guys,

I have a scuf infinity 4PS controller, that is acting up.
The R2 button is unresponsive. However, if I remove the scuf ribbon cable, then it works fine, but I obviously lose the use of my rear paddles.

Looking at the scuf ribbon cable, I can’t see any breaks in the traces or anything, it looks fine, but for some reason it is not detecting R2.

Can anyone help with this?
