The low speed noise when descelerating is CVT related however, as your SA told you also engine makes similar noise. If you drive very slowly, little throttle you have this whoewhoeeee noise, this is the Airco compressor. You can see if you switch of aircon during the noise. Those two are very similar. But as you say, it's not that bad, all gears make noise, some just isolate it better than other. For me it's not bothering. We take in into consideration however and it is one of the action point to further improve on this matter.
thanks...at least, it is not something abnormal. i will try other methods to insulate the noises from the engine bay.
for the second time, i felt the "jerking" issue. both incidents were during cold engine. i started the engine, and straight switched to "D" and drove forward. Seconds later when reached a turning, slow down, and without a full stop, i pressed the pedal and continue turning and driving forward. that was the time when i felt the car moved a bit, then a sudden loss of power(like the gear could not hold well, or the cluth open?) for a second, then the power came back (like the gear hold back, or cluth close?) and this caused the jerk. Normal?
