Exhaust Fumes..

[kace]

Hi,
 

During normal use, i smell exhaust fumes coming through the ventilatiors inside my cabin, moreso when I dont wind my windows down.  It is not potent, definately noticable though.  Any ideas what may be causing this.  I took her in for a service a few weeks back thinking that it will cure it, same problem though.

Thanks

Leaking exhaust manifold? what does the engine sound like when you rev it?
