Hi guys,

I've had a Redline A5 '07 for 6 weeks now and my life has changed. I thought I was over my car liking days, but now I'm obsessed with driving again!

Anyway, when I start up my Z, the tacho sits on 2,000 rpm as it would for all of you. As the revs come down, a high pitched vibrating sound can be heard coming from the outside, or even at normal idle speeds.

Has anyone had this problem? What's causing it?

 

Any more specific information as to where the sounds seems to be coming from? Engine bay? Rear of car? Towards firewall, front bumper, under car, etc.

 

It seems to be coming from underneath the car, around where the rear axle is. Could it be a loose exhaust mount?
