DDJ 1000 Crossfader Issue

Hi all. I have had my DDJ 1000 for over a year, and with all the firmware updates etc, I am still experiencing an issue with my crossfader. With the crossfader in the centre, in RB it is maybe 10-15% to the left. I have yet to see a resolution to this on the Forums. It is a right PITA managing transitions, seeing inconsistent volume levels in the mix. PLEASE HELP!!!
