Hoping someone may have come across this. Z4m e85.
Have a wind blowing noise very faint behind the dash. Occurs from about 10mph onwards, does not get louder with speed. Like there's a hole somewhere on the bulkhead allowing air through to the dash.
Tried fans and ac on and off. Different fan blower positions but does not change.
Becomes very slightly louder when turning gently left or right at 10mph and above.
Any ideas?
Cheers
