M135i
Went on the motorway today and as soon as i start to build speed up ( hitting 70) a whistle noise started asif air noise was getting inside the car (the noise you get from opening you window on the motorway)
The faster i went the louder it got, Both windows were 100% shut and both door were shut properly.
Any ideas what or where it could be coming in ?
Maybe a broken seal somewhere ?
