Left analog stick when moved to the left also activates R2 button

I would spray some WD40 contact spray at the sides of all buttons and toggles once you have done this keep pressing all the buttons and moving the toggles so the spray seeps in. Make sure you turn power off to the console. DO NOT USE THE NORMAL WD40 it has to be the contact WD40 you can purchase this from Amazon or Euro car parts. If it doesn't work the first time, do it again. Make sure you spray it down the side of the buttons and around the round buttons
