Sorry, but I find this doubtful. Mine was purchased in March(newer than yours) and my dealer has replaced about 50 of the springs and washers, mine included. My dealer has been great about it and has replaced them with a smile, problems during BSR or not. If I were you, I'd push for the replacement. You shouldn't have to argue to get a free retrofit from Bernina! Worst case, fib and say you're still having issues and want the new spring. Period.
