Billy, do your blue light issues only appear when the pump is in the the docking station? The reason I ask is we have an infusomat here that after I did a P2 connector replacemant (one of many I hasten to add with no problems previous) seemed to work fine until it was placed in a docking station to charge the battery, when the blue light continually flashed. After speaking to Braun, apparently the station talks to the pump when it is first put in and gets its serial number. If it doesn't get the number it keeps trying. They suggested possible damage to the board during the P2 replacement and would require a maind board.
The joys of Braun.
