I think the TT stator is in order. I have the XC-W, with a fan, but my bike won't start with the button at all, even with a fresh battery. It is in the shop right now getting a new starter and possibly some kind of wrong way bearing. It kickstarts pretty easy though, But I still want my button to work. I ride with a guy who has an 08 530 XC-W. He had to upgrade to the TT to keep his battery charged. Running his lights seemed to kill his battery. He is good now with the TT stator. The dealer told me, in his opinion, that the charging system was adequate, but, slow, tight riding, fan running a lot, long term, will kill the battery. I say get the TT or ride faster to keep it charged.
