Hey all,

I have a metallic whistle noise coming from my engine,(imagine The Terminator whistling lol). Its only noticable when revving in neutral and letting the revs drop. Is this normal? Like I said, its not a loud whistle, just noticeable when the CD players turned off and the revs drop.

Cheers!!

Sounds like it might be the alternator (sounds like Terminator!!) It tends to make a noise when its cold or when you are using the heated screen/s.
See if it persists but I would imagine its not too much of a problem, mine does it from time to time.
