I have the same problem as well , Full bolt on . It only happens when I'm in sport mode and manually shifting gears in higher rpm , it's almost like it starts bucking . No codes are thrown . When in auto it's fine , though sometimes when cruising I might feel a light surge but not sure if it's related . 09 335i msport , 50k miles
