Time to kick this one into touch seeing as the Turbo Actuator rod RATTLE thread is all but dead. Since day 1, my car has made a weird noise on startup....and only on startup, when the STOP START kicks in later! the noise isn't there so I'm presuming its normal. I can only describe it as a kind of howl, like a cartoon cat yawning???? It doesn't sound mechanical but it is identical each and every time. Im sure there was a similar thread with a sound bite and they had an identical noise.....this happens regardless of outside temp or AC on or off.....thanks in advance!!!
