Well I thought I solved this problem by disconnecting the 'support battery' in my V60. It worked great for a day. Today though even with the support battery disconnected, the car uses the Start'Stop for one or two cycles, then shows a message that the Start'Stop system needs service, then disables Start/Stop for the remainder of the trip. When the car is restarted, same thing. So it just "kind of" works, but not a clean solution. So, back to the drawing board..... oh well.
