MCSa 08, still running-in (300 miles),
intermitent, very short duration chirping noise when car goes thru bumpy road, the pitch of the noise seems to correlate to engine rpm, (i.e. when accelerate thru bumpy the chirps pitch is higher compare to when coasting)
anybody has this??
first I thot it was the belt but when the car is not moving, at any given rpm it doesn't make that chirp, just the "usual" click on idle (direct injector pump?)

no checked engine light, dont feel any loss of power (still brand new i guess).. just that annoying chirps that seems to relate to when engine shakes
