Hello guys I am curious if anyone here ever ran into issue on mark1 audi tt where the dash causes battery drain/draw? I have heard of various issues but never this. According to diagnostic work performed, found that the dash is causing battery draw. Curious if 2J47Y replacement is necessary or just reflash for HC12 Mcu? Anyone have any more information on this issue or how to repair?

Is a reflash enough to fix the issue or need to change 2J47Y?
