Just checked mine, and the button stayed down. Mileage 1600 . Bike kept in garage and not used since the end of September. I used AC 50 and GT85 moving the button up and down with my fingers for about 30 minutes. It started to return little by little and eventually sprung back as it should, working perfectly. I'm certain that that's all a dealer would do; and the thought of the hassle to book it in and leave it there, when its a simple easy fix you can do yourself .
