[v57]

about 2 or 3 days ago, i was driving in sport mode. i notice that in 4th and 2nd gear there is a noticeble noise in fornt of me, so i tird in other gears and listen very carefully . it seems that only happens in 2nd 4th and 6 when i hit 4000rpm up and let go the gas pedle during the rav drop in sport and s-sport mode. (same gear same rav in manual = no problem )

please give advice
