CTR weird engine noise...

[Animal]

Have noticed a weird noise coming from the front end (assume engine) that sounds like a light spring or similar vibrating very quickly (almost like a 'fizzing'). It only ever happens between 3,000 and 3,400 rpm irrespective of whether I'm accelerating, decelerating or on a constant throttle.

Car is only at 25k miles ('03 plate) so I would hope nothing serious...

Anyone else have similar experiences or am I the special one?!

Back to the dealers for a warranty job then!
