Problems ALREADY! (engine knocking at certain RPM - HR16DE - solved)

[AlphaMicra]

The A/C is very loud, as are other aspects of the engine. In the tradition of every other Micra that has come before, there is little to no sound deadening material. The compressor is startlingly loud when it comes on for the first time; I've tested this in other brand new Micra's on the lot, and it's exactly the same. I think what you might be hearing at startup are the injectors.

Personally, I enjoy hearing every aspect of the engine. While alarming at first, I have become accustomed to the various sounds and know what to expect, so now if something is not working right, I should be able to hear it before it becomes something major.

The clutch for the ac fan kicking in an out can be loud, but nothing to worry about. You can remedy this simply my turning off your AC until the car has warmed up.
