Hopefully posting this in the right area.
Just acquired this B6 w/ TMCC, and everything works fine except the sounds never come out of idle. When it starts to move I may (or may not) get one chuff, and it keeps playing all the normal idle sounds while running. The smoke is puffing in sync while running. I thought about the chuff switch (I've replace those before), but doesn't that sync the smoke too? Or is it a mechanical sync?
Thanks.
