I just purchased a 2001 Type-S and noticed what sounds like a vibration once I shift from reverse to drive and begin acceleration. The sound is similar to the side-view mirror motor, however, can confirm that it is not the side-view mirror.

The sound appears to be coming from the dash. It is replicable, and appears to sound once or twice, but that's all. This sound does not seem to appear when I am already in drive and accelerate after being at a stop light. It just appears to happen a few moments after I shift from Reverse to Drive and increasing my speed under light acceleration. Once my speed increases a little more, I have heard the same sound (vibration) again.

Any thoughts to what this may be?

 

VSA system running it's self check on the ABS pump. This test occurs once every drive cycle. Perfectly normal.

 

Appreciate the info! This is exactly what the noise is!
